WeEn Semiconductors announced an expansion to its range of high-performance and rugged IGBTs. Offering voltage ratings of 650V and 1200V, the new devices incorporate a fast recovery anti-parallel diode and boast extremely low leakage currents and exceptional conduction and switching characteristics at both high and low junction temperatures.
Based on an advanced fine trench gate field-stop (FS) technology, the new IGBTs provide a more uniform electric field within the chip, support higher breakdown voltages and offer improved dynamic control. By offering the optimum trade-off between conduction and switching losses, as well as an enhanced EMI design, the devices will maximize efficiency in a wide variety of mid- to high-switching-frequency power conversion designs.
The new IGBTs offer ratings of 650V/75A, 1200V/40A and 1200V/75A and are supplied in TO247 or TO247-4L packages depending on the selected device. All of the devices will operate with a maximum junction temperature (Tj) of 175 °C and have undergone high-voltage H3TRB (high-humidity, high-temperature and high-voltage reverse bias) and 100%-biased HTRB (high-temperature reverse bias) tests up to this maximum.
Target applications for the new WeEn IGBTs include solar inverters, motor control systems, uninterruptible power supplies (UPS) and welding. A positive temperature coefficient simplifies parallel operation in applications where higher performance is required, while options for bare die, discrete and module product variants provide flexibility for a wide variety of target designs.

The latest onsemi 7th generation 1200V QDual3 Insulated Gate Bipolar Transistor (IGBT) power modules offer increased power density and deliver up to 10% more output power than other available competing products. Based on the latest Field Stop 7 (FS7) IGBT technology, the 800-amp (A) QDual3 module delivers industry-leading efficiency to reduce system costs and simplify designs.
In a 150KW inverter, the QDual3 module will dissipate 200 watts (W) less in losses compared to the closest competition, significantly reducing heatsink size. QDual3 is engineered to work under harsh conditions and is ideal for high-power electronics converters such as central inverters in solar farms, energy storage systems (ESS), commercial agricultural vehicles (CAVs) and industrial motor drives.
Currently, two products are available depending on the applications – NXH800H120L7QDSG and SNXH800H120L7QDSG.
Increasing renewable energy adoption amplifies the need for solutions that can manage peak demand and ensure continuous power supply. Peak shaving, the practice of reducing electricity use during peak hours, is essential for maintaining electric grid stability and reducing costs. Using the QDual3 modules, manufacturers can construct a solar inverter and ESS that output more power in the same system size, enabling more efficient energy management and storage capabilities, and allowing for a smoother integration of solar power into the grid.
The modules also mitigate the intermittency of solar energy by storing excess power in an ESS, ensuring a reliable and consistent energy flow. For large systems, the modules can be paralleled to increase the output power up to a couple of MWs and compared to traditional 600 A module solutions, the 800 A QDual3 significantly reduces the module quantity, greatly simplifying design complexity and cutting system costs.
The QDual3 IGBTs module features an 800 A half-bridge configuration that integrates the latest Gen7 trench Field Stop IGBT and diode technology using onsemi’s advanced packaging techniques to reduce switching and conduction losses.
With FS7 technology, the die size is reduced by 30%, allowing more die per module, increasing the power density to enable the maximum current capacity up to 800 A or higher. With an IGBT Vce(sat) as low as 1.75V (175°C) and low Eoff, the 800 A QDual3 module dissipates 10% lower energy losses than the next-best alternative. The modules also meet the stringent standards required of an automotive application.
“Increased electrification of commercial fleets such as trucks and busses and the need of renewable energy sources demand solutions that can generate, store and distribute power more efficiently. Transferring energy from renewable sources to the grid, storage systems and to downstream loads with the lowest power losses possible is increasingly critical,” said Sravan Vanaparthy, vice president, Industrial Power Division, Power Solutions Group, onsemi. “With its industry-standard pin-out and market-leading efficiencies, QDual3 enables power electronics designers to plug and play these modules for an immediate performance boost in their systems.”

To provide higher efficiency and power density for telecom, industrial, and computing applications, Vishay Intertechnology, Inc. introduced its first fourth-generation 600 V E Series power MOSFET in the new PowerPAK® 8 x 8LR package.
Compared to previous-generation devices, the Vishay Siliconix n-channel SiHR080N60E slashes on-resistance by 27 % and resistance times gate charge, a key figure of merit (FOM) for 600 V MOSFETs used in power conversion applications, by 60 % while providing higher current in a smaller footprint than devices in the D²PAK package.
Vishay offers a broad line of MOSFET technologies that support all stages of the power conversion process, from high voltage inputs to the low voltage outputs required to power the latest high tech equipment. With the SiHR080N60E and other devices in the fourth-generation 600 V E Series family, the company is addressing the need for efficiency and power density improvements in two of the first stages of the power system architecture — power factor correction (PFC) and subsequent DC/DC converter blocks.
Typical applications will include servers, edge computing, super computers, and data storage; UPS; high intensity discharge (HID) lamps and fluorescent ballast lighting; telecom SMPS; solar inverters; welding equipment; induction heating; motor drives; and battery chargers.
Measuring 10.42 mm by 8 mm by 1.65 mm, the SiHR080N60E’s compact PowerPAK 8 x 8LR package features a 50.8 % smaller footprint than the D²PAK while offering a 66 % lower height. Due to its top-side cooling, the package delivers excellent thermal capability, with an extremely low junction to case (drain) thermal resistance of 0.25 °C/W.
This allows for 46 % higher current than the D²PAK at the same on-resistance level, enabling dramatically higher power density. In addition, the package’s gullwing leads provide excellent temperature cycle capability.
Built on Vishay’s latest energy-efficient E Series superjunction technology, the SiHR080N60E features low typical on-resistance of 0.074 Ω at 10 V and ultra low gate charge down to 42 nC. The resulting FOM is an industry-low 3.1 Ω*nC, which translates into reduced conduction and switching losses to save energy and increase efficiency in power systems > 2 kW.
For improved switching performance in hard-switched topologies such as PFC, half-bridge, and two-switch forward designs, the MOSFET released today provides low typical effective output capacitances Co(er) and Co(tr) of 79 pF and 499 pF, respectively. The package also provides a Kelvin connection for improved switching efficiency.
The device is RoHS-compliant and halogen-free, and it is designed to withstand overvoltage transients in avalanche mode with guaranteed limits through 100 % UIS testing.
