Nexperia announced the launch of 16 new 80 V and 100 V power MOSFETs in the innovative copper-clip CCPAK1212 package, delivering industry-leading power density and outright performance. The innovative copper-clip design provides high current conduction, reduced parasitic inductance, and excellent thermal performance. These features make the devices ideal for motor control, power supplies, renewable energy systems, and other power-hungry applications.
The range also includes application-specific MOSFETs (ASFETs) designed for AI server hot-swap functions. With top-side and bottom-side cooling options, these MOSFETs in CCPAK provide high power density and reliable solutions. All devices are supported by JEDEC registration and Nexperia’s interactive datasheets for seamless integration.
The benchmark PSMN1R0-100ASF is a 0.99 mΩ 100 V power MOSFET capable of conducting 460 A and dissipating 1.55 KW of power, yet in a CCPAK1212 package footprint that occupies only 12mm x 12mm of board space. The PSMN1R0-100CSF offers similar statistics in a top-side cooled version.
The secret to this impressive performance is the internal construction of the devices. The “CC” in CCPAK1212 stands for copper clip, meaning that the power MOSFET silicon die is sandwiched between two pieces of copper, the drain tab on one side and the source clip on the other. With wire bonds entirely eliminated, such an optimized assembly offers a low on-resistance, reduced parasitic inductances, high maximum current ratings and excellent thermal performance.
CCPAK1212 NextPower 80/100 V MOSFETs are recommended for power-hungry industrial applications where high efficiency and high reliability are critical, including brushless DC (BLDC) motor control, switched-mode power supplies (SMPS), battery management systems (BMS) and renewable energy storage. The availability of such power-capable MOSFETs in a single package reduces the need for parallelism, simplifying designs and offering more compact, cost-effective solutions.
The Nexperia CCPAK1212 announcement also includes some new application specific MOSFETs (ASFETs) targeting the hot-swap function in increasingly powerful AI servers. These devices feature an enhanced safe operating area (SOA), providing superior thermal stability during linear mode transitions.
Across all these applications, the availability of top-side and bottom-side cooling options provides engineers a choice of thermal extraction techniques, especially helpful where dissipating heat through the PCB is impractical due to the sensitivity of other components.
“Despite offering market-leading performance, we know that some customers will be reticent to design-in a relatively new package”, stated Chris Boyce, Product Group General Manager at Nexperia. “For this reason, we have registered the CCPAK1212 with the JEDEC standards organization (reference MO-359). We followed a similar approach when we introduced the first LFPAK MOSFET package some years ago and as a result there are now many compatible devices available in the market. You are never on your own for long when your innovations offer genuine value to your customers”, concluded Boyce.
All the new CCPAK1212 MOSFET devices are supported with a range of advanced design-in tools, including thermally compensated simulation models. Traditional PDF datasheets are supplemented with Nexperia’s user-friendly interactive datasheets, which now incorporate a new “graph-to-csv” feature that allows engineers to download, analyze and interpret the data behind each device’s key characteristics. This not only streamlines the design process but enhances confidence in design choices.
Nexperia plans to extend CCPAK1212 packaging to power MOSFETs across all voltage ranges and also to its automotive qualified AEC-Q101 portfolios, addressing the evolving demands of next-generation systems with the highest current and thermal performance requirements.

To provide higher efficiency and power density for telecom, industrial, and computing applications, Vishay Intertechnology, Inc. introduced a new 150 V TrenchFET® Gen V n-channel power MOSFET in the PowerPAK® SO-8S (QFN 6×5) package.
Compared to previous-generation devices in the PowerPAK SO-8, the Vishay Siliconix SiRS5700DP slashes overall on-resistance by 68.3% and on-resistance times gate charge — a key figure of merit (FOM) for MOSFETs used in power conversion applications — by 15.4% while providing 62.5% lower RthJC and 179 % higher continuous drain current.
With the industry’s lowest on-resistance of 5.6 mΩ at 10 V and on-resistance times gate charge FOM of 336 mΩ*nC, the device released today minimizes power losses from conduction. This allows designers to boost efficiency to meet next-generation power supply requirements, such as 6 kW AI server power systems. In addition, the extremely low 0.45 °C/W RthJC of the PowerPAK SO-8S package enables continuous drain current up to 144 A to increase power density while providing robust SOA capability.
The SiRS5700DP is ideal for synchronous rectification, DC/DC converters, hot swap switching, and OR-ing functionality. Typical applications will include servers, edge computing, super computers, and data storage; telecom power supplies; solar inverters; motor drives and power tools; and battery management systems. RoHS-compliant and halogen-free, the MOSFET is 100 % Rg and UIS tested and complies with IPC-9701 criteria for more reliable temperature cycling. The device’s standard 6 mm by 5 mm footprint is fully compatible with the PowerPAK SO-8 package.

The safe hot-swap operation in AI servers and telecom requires MOSFETs with a robust linear operating mode as well as a low R DS(on). Infineon Technologies AG addresses this challenge with the new OptiMOS™ 5 Linear FET 2, a MOSFET designed to provide the ideal trade-off between the R DS(on) of a trench MOSFET and the wide safe operating area (SOA) of a classic planar MOSFET.
The device prevents damage to the load by limiting the high inrush current and ensures minimal losses during operation due to its low R DS(on). Compared to the previous generation (the OptiMOS Linear FET), the OptiMOS Linear FET 2 offers improved SOA at elevated temperatures and reduced gate leakage current, as well as a wider range of packages. This allows for more MOSFETs to be connected in parallel per controller, reducing bill-of-material (BOM) costs and offering more design flexibility due to the extended product portfolio.
The 100 V OptiMOS 5 Linear FET 2 is available in a TO-leadless package (TOLL) and offers a 12 times higher SOA at 54 V at 10 ms and 3.5 times higher SOA at 100 µs compared to a standard OptiMOS 5 with similar R DS(on). The latter improvement is particularly important for the battery protection performed inside the battery management system (BMS) in case of a short circuit event. During such events the current distribution between parallel MOSFETs is critical for the system design and reliability.
The OptiMOS 5 Linear FET 2 features an optimized transfer characteristic that allows for improved current sharing. Taking into account the wide SOA and improved current sharing, the number of components can be reduced by up to 60 percent in designs where the number of components is determined by the short-circuit current requirement. This enables high power density, efficiency, and reliability for battery protection which are used in a wide range of applications including power tools, e-bikes, e-scooters, forklifts, battery back-up units and battery-powered vehicles.
The new OptiMOS 5 Linear FET 2 MOSFET is now available. Further information can be found at www.infineon.com/optimos-linearfet and www.infineon.com/ipt023n10nm5lf2.

Toshiba Electronics Europe GmbH has developed new 1200V silicon carbide (SiC) MOSFETs with low on-resistance (RDS(ON)) and high levels of reliability. The devices are particularly suited to applications within automotive traction inverters. They are now available and shipping as early test samples in bare die format – allowing customers to customise them to meet the needs of their applications.
The new X5M007E120 uses a manufacturing process that reduces on-resistance per unit area by up to 30%. Unlike existing methods that utilise a striped-pattern construction, the new devices arrange the embedded Schottky barrier diodes (SBDs) in a check-pattern to achieve lower on-resistance.
Many SiC MOSFETs increase on-resistance as body diodes are energised during reverse conduction, which can lead to reliability issues. Toshiba SiC MOSFETs alleviate this issue by preventing body diodes from operating as SBDs are embedded into the MOSFETs. This approach maintains the reduction in on-resistance while ensuring reliability during reverse conduction.
With electric motors consuming over 40% of the world’s electrical energy, efficient operation is essential to sustainability. The re-arrangement of SBDs in this device has suppressed body diode energisation, and the upper limit of unipolar operation has increased to around double without increasing the SBD mounting area. Additionally, channel density is improved. These enhancements contribute to energy efficiency in applications, including motor control inverters.
Reducing RDS(ON) within a SiC MOSFET can cause excess current flow during short-circuit operations. By adopting a deep barrier structure, the X5M007E120 reduces excessive current within the MOSFET section and leakage current in the SBDs section during short-circuit operation. This enables durability during short-circuit conditions while maintaining high levels of reliability against reverse conduction operation.
The new X5M007E120 has a VDSS of 1200V and is rated for a drain current (ID) of 229A continuously, with 458A for pulsed operation (ID Pulse). RDS(ON) is as low as 7.2mΩ, and the device can operate with channel temperatures (Tch) as high as 175°C. The devices are AEC-Q100 qualified for automotive applications.
Engineering samples of the new X5M007E120 are expected to ship during 2025, with mass production samples scheduled to start in 2026.
Toshiba will continue to seek ways to further improve the characteristics of its products. The company will contribute to realising a decarbonised society by providing customers with power semiconductors for applications where energy efficiency is essential, such as inverters for motor control and power control systems for electrical vehicles.
