Nexperia introduced a 650 V Silicon Carbide (SiC) Schottky diode designed for power applications which require ultra-high performance, low loss, and high efficiency. The 10 A, 650 V SiC Schottky diode is an industrial-grade part that addresses the challenges of demanding high voltage and high current applications. These include switched-mode power supplies, AC-DC and DC-DC converters, battery-charging infrastructure, uninterruptible power supplies and photovoltaic inverters and allow for more sustainable operations. Data centers, for example, equipped with power supplies designed using Nexperia’s PSC1065K SiC Schottky diode will be better placed to meet rigorous energy efficiency standards than those using solely silicon-based solutions.
The PSC1065K delivers leading-edge performance with temperature-independent capacitive switching and zero recovery behavior culminating in an outstanding figure-of-merit (QC x VF). Its excellent switching performance is almost entirely independent of current and switching speed variations. The merged PiN Schottky (MPS) structure of the PSC1065K provides additional benefits, such as outstanding robustness against surge currents that eliminates the need for additional protection circuitry. These features significantly reduce system complexity and enable hardware designers to achieve higher efficiency with smaller form factors in rugged high-power applications. Designers can be further reassured by Nexperia’s proven reputation as a supplier of high-quality products in a range of semiconductor technologies.
This SiC Schottky diode is encapsulated in a Real-2-Pin (R2P) TO-220-2 through-hole power plastic package. Additional package options include the surface mount (DPAK R2P and D2PAK R2P) and through-hole (TO-247-2) with a real 2-pin configuration that enhances reliability in high-voltage applications at temperatures up to 175 °C.
Katrin Feurle, Senior Director of the Product Group SiC at Nexperia, adds: “We are proud to offer a high-performance SiC Schottky diode that ranks among the top tier of currently available solutions. In an increasingly energy-conscious world, we are bringing greater choice and availability to the market as demand for high-volume, high-efficiency applications increases significantly.”
Nexperia plans to continuously augment its portfolio of SiC diodes by including automotive-grade parts that operate at 650 V and 1200 V voltages with currents in the 6-20 A range. Samples and production quantities of the new SiC diodes are available now.

Power electronics technologies have undergone a radical transformation following the introduction of wide-bandgap (WBG) devices, such as silicon carbide (SiC) and gallium nitride (GaN). These materials, in fact, have characteristics that make them particularly suitable for applications that operate at high voltages and high switching frequencies. To fully exploit the potential offered by wide-bandgap semiconductors, designers must understand the challenges of these materials.
Power electronics design will continue to focus on reducing the size and complexity of devices while increasing their functionality. The design will increasingly incorporate AI and machine learning algorithms to improve performance, monitor system health, and optimize energy management. Future developments will be integrated not only in automotive, industrial, aerospace markets, but also with IoT technologies to create a more connected and automated energy system.
Semiconductor devices are used to drive motors and control power. As efficiency standards for these applications get better, cost-effective and energy-efficient control solutions, test and measurement solutions, and transducers/sensors make design easier and offer a high level of integration, as well as better safety features and certified isolation capabilities.
Moreover, using energy harvesting techniques and new power semiconductors to make electrical and electronic systems work as well as possible is an important part of engineering.

It’s been 6 months since CIL announced it’s newly created and UK based advanced semiconductor packaging facility. Contained within the 46,000sq ft facility is a 15,000sq ft ISO7 (Class 10,000) fully qualified cleanroom that is starting to come online and will be ready by late May 2023.
Since last announced, CIL has also taken the decision to segregate part of this cleanroom to add a separate wafer dicing area complete with DISCO DAD3361 dicing saw and all of the necessary ancillary equipment. This equipment is already installed, commissioned and currently running early engineering trials. This wafer dicing equipment and all of CIL’s current micro-electronics and power semiconductor device packaging equipment will then start to transfer out of CIL’s existing facilities in Andover UK from late May 2023 onwards. The equipment and facilities to be transferred are initially the following:
- 1 off DISCO DAD3361 die and device wafer saw system complete with wafer mounting equipment.
- 2 off DATACON 2200EVO Automatic die bonders for power die placement using both SiC & GaN

- 1 off Scheugenpflug VDS U1000 / LP804 VDU Auto epoxy fill system
- 1 off high power 2000W laser welding system for copper busbar welding
- 6 off 3D Printers
- 50 staff of which 30 are engineers
CIL believes this facility, process equipment and staff will create the largest semiconductor packaging facility in the UK. It is to support and grow its existing micro-electronics customers and to commercially exploit its WBG power semiconductor capability that has been generated from various “Net Zero” low carbon projects funded by APC / InnovateUK / DCMS / BEIS using the latest SiC and GaN devices as well as commercially funded projects.
By adding the wafer dicing capability to the facility, CIL will be able to process finished wafers to provide Dicing, Die attach, Wire bonding or power device copper clip attach, glob top, full plastic overmold or potting and back these processes up with inspection equipment that includes, X-Ray, CT-Scan, CSAM, VHX7000, and destructive and non-destructive testing using DAGE 4000 and DAGE PROSPECTOR test stations.
Over the last 3-4 years CIL has grown its engineering department from 8 persons to the 32 persons it has currently and also has a further 10 engineering vacancies. Starting in late May 2023, all of the staff involved in CIL’s semiconductor and power packaging activities will move from CIL’s two existing facilities into this new world class and state of the art semiconductor packaging facility. As with the cleanroom, the offices are nearing completion and will initially house around 30 semiconductor packaging engineers of all levels.
To compliment this semiconductor packaging facility, CIL has also upgraded its existing SMT PCBA equipment consisting of 5 SMT lines and associated 3D AOI, Flying probe test and IPC2 / 3 soldering at its CIL House facility also in Andover UK. This facility totalling 24,000sq ft is being steadily upgraded and added to.
In the last 2 years, CIL has seen its turnover increase from £15M to £27M and headcount increase from 135 persons to 187 persons it has today. Over the next 12 months, as well as bringing on line its advanced semiconductor packaging facility, it will also be adding new processes and equipment to its current PCBA service offering to further support both its customers development and production needs. So with the new packaging facility this will give CIL a total of 80,000sq ft of production space at its three Andover UK sites.

The technology group ZF will, from 2025, purchase silicon carbide devices from STMicroelectronics. Under the terms of the multi-year contract, ST will supply a volume of double-digit millions of silicon carbide devices to be integrated in ZF’s new modular inverter architecture going into series production in 2025. ZF will leverage ST’s vertically integrated silicon carbide manufacturing in Europe and Asia to secure customer orders in electromobility.
“With this strategically important step, we are strengthening our supply chain to be able to securely supply our customers. Our order book in electromobility until 2030 now amounts to more than thirty billion euros. For this volume, we need several reliable suppliers for silicon carbide devices,” says Stephan von Schuckmann, member of the ZF Board of Management responsible for electromobility as well as materials management. “In STMicroelectronics, we now have a supplier whose experience with complex systems meets our requirements and who, above all, can produce the devices in exceptionally high quality and at the required quantities.” With this agreement, ZF has gained a world-class supplier for silicon carbide technology, in addition to ZF’s existing partnership agreement on silicon carbide technology announced in February.
“As a vertically integrated company, we are investing heavily to expand capacity and develop our silicon carbide supply chain to support our global and European customers across automotive and industrial sectors, as they pursue electrification and decarbonization targets,” says Marco Monti, President Automotive and Discrete Group of STMicroelectronics. “The key to success in electric vehicle technology is greater scalability and modularity with increased efficiency, peak power, and affordability. Our silicon carbide technologies help deliver these benefits and we are proud to work with ZF, a leading automotive supplier for electrification, to help them differentiate and optimize the performance of their inverters.”
ST will manufacture the silicon carbide chips at its production fabs in Italy and Singapore with packaging of the chips into STPAK, an ST-developed advanced package, and testing at its back-end facilities in Morocco and China.
ST will supply ZF from 2025 with a volume of double-digit millions of third generation silicon carbide MOSFET devices. ZF can connect a variable number of such devices together to match customers’ performance requirements without changing the design of the inverter. Among others, ZF will use the technology in inverters for vehicles of a European car manufacturer whose production start is planned for 2025.
The inverter is the brain of electric drivetrains. It manages the flow of energy from battery to e-motor and vice versa. Inverters have become more efficient and more complex with every development step. The combination of the inverter design and the semiconductors, like silicon carbide, is the key to improving electric vehicle performance. Silicon carbide devices significantly reduce power losses in electric car inverters, as well as in wind turbine and photovoltaic inverters. Devices made with silicon carbide have decisive advantages over conventional silicon-based products, such as higher efficiency, power density and reliability. At the same time, they enable smaller and more cost-effective system designs. Simply put, an electric vehicle charges faster, drives further and has more space when equipped with silicon carbide-based semiconductors.

DENSO CORPORATION announced that it has developed its first-ever inverter with silicon carbide (SiC) semiconductors. This inverter, which is incorporated in the eAxle, an electric driving module developed by BluE Nexus Corporation, will be used in the new RZ, Lexus’ first dedicated battery electric vehicle (BEV) model has been released on March 30, 2023.
SiC power semiconductors consist of silicon and carbon that significantly reduce power loss compared with silicon (Si) power semiconductors. The verification of cruising test in a certain condition, which test was performed by BEV consisted of SiC semiconductor inverters, demonstrated inverters with SiC power semiconductor reduce power loss less than half of ones with Si semiconductor. As a result, the energy efficiency of BEVs is improved and cruising range is extended.
Key elements of developing the new inverter:
- SiC power semiconductors with DENSO’s unique trench-type metal-oxide-semiconductor (MOS) structure improve the output per chip due to reducing the power loss caused by heat generated. The unique structure achieved high voltage and low on-resistance operation.
Key elements of manufacturing the new inverter:
- Based on the high-quality technology jointly developed by DENSO and Toyota Central R&D Labs., Inc., we utilize SiC epitaxial wafers that incorporate the results of work commissioned by New Energy and Industrial Technology Development Organization (NEDO). As a result, we have halved the number of crystal defects that prevent the device from operating normally due to the disorder of the atomic arrangement of the crystal.
- By reducing crystal defects, the quality of SiC power semiconductor devices used in vehicles and their stable production are ensured.
DENSO calls its SiC technology “REVOSIC®,” and uses it to comprehensively develop technologies for products ranging from wafers to semiconductor devices and modules such as power cards.
DENSO will contribute to the realization of a carbon-neutral society through development aimed at more efficient energy management for vehicles, while also utilizing the grant from Green Innovation Fund (GI Fund), which was adopted in 2022.
