ROHM has developed automotive-grade AEC-Q101 qualified 4th Generation 1200V IGBTs that combine class-leading low loss characteristics with high short-circuit resistance. This makes the devices ideal for vehicle electric compressors and HV heaters as well as industrial inverters.
The current lineup includes RGA80TRX2HR / RGA80TRX2EHR / RGA80TSX2HR / RGA80TSX2EHR – in two discrete package types (TO-247-4L and TO-247N), along with 11 bare chip variants – SG84xxWN – with plans to further expand the lineup in the future.
The increasing use of higher voltages in automotive systems and industrial equipment has led to a growing demand for power devices capable of handling high voltages in applications such as vehicle electric compressors, HV heaters, and inverters for industrial equipment.
At the same time, there is a strong push for high efficiency power devices to improve energy conservation, simplified cooling mechanisms, and smaller form factors for a decarbonized society. Automotive electrical components must also comply with automotive reliability standards, while power devices for inverter and heater circuits are required to provide current interruption capabilities during short circuits, necessitating high short-circuit tolerance.
In response, ROHM redesigned the device structure and adopted an appropriate package to develop new 4th Generation IGBTs suitable for high voltage by delivering industry-low loss characteristics with superior short-circuit tolerance.
These devices achieve an industry-leading short-circuit withstand time of 10µs (Tj=25°C) together with low switching and conduction losses while maintaining a high withstand voltage of 1200V and meeting automotive standards by reviewing the device structure, including the peripheral design. At the same time, the new TO-247-4L package products, which feature 4 terminals, can accommodate an effective voltage of 1100V in a ‘Pollution Degree 2 environment’ by ensuring adequate creepage distance between pins. This enables support for higher voltage applications than conventional products.
Implementing creepage distance measures on the device side alleviates the design burden for manufacturers. On top, the TO-247-4L package achieves high-speed switching by including a Kelvin emitter terminal, resulting in even lower losses. In fact, when comparing the efficiency of the new TO-247-4L packages with conventional and standard products in a 3-phase inverter, loss is reduced by about 24% compared to standard products and by 35% over conventional products – contributing to higher efficiency in drive applications.
ROHM will continue to expand its lineup of high-performance IGBTs that contribute to greater miniaturization and high efficiency drive in automotive and industrial equipment applications.

Efficient Power Conversion (EPC) announced that the Full Commission of the U.S. International Trade Commission (ITC) has affirmed the ITC’s initial determination that Innoscience infringed EPC’s foundational patent for GaN technology, which is core to applications involving artificial intelligence, satellites, rapid chargers, humanoid robots, and autonomous driving, among others. The decision imposes a ban on Innoscience (Zhuhai) Technology Co., Ltd. and its affiliates (Innoscience) from importing GaN-related products into the United States without a license from EPC.
This milestone decision marks the first successfully litigated U.S. patent dispute involving GaN-based wide bandgap semiconductors and solidifies EPC’s position as a leading developer of these next-generation devices, which are significantly more efficient, faster, and smaller than traditional, silicon-based technology. The decision also paves the way for EPC to expand access to its IP through licensing agreements with potential partners and customers around the world.
“After pouring nearly two decades and immense resources into developing our uniquely valuable intellectual property portfolio, this is a tremendous victory for EPC and a major win for fair competition globally, which is critical to the success of next-generation technological advances. We are grateful to the ITC for their diligent work in recognizing the validity of our patents and Innoscience’s infringement,” said Alex Lidow, CEO and Co-Founder of EPC. “EPC will continue to vigorously defend our IP against unfair use to ensure that we can continue to innovate and provide our customers with the cutting-edge technologies needed to help power our future.”
The ITC’s most recent decision is the fourth time that EPC’s IP rights have been affirmed against Innoscience in the past six months. EPC initially filed the infringement claim against Innoscience in the ITC in May 2023. In response, Innoscience challenged the validity of the EPC patents at issue in the U.S., as well as EPC’s counterpart patents in China.
The China National Intellectual Property Administration upheld the validity of EPC’s counterpart patents in April and May 2024. The ITC’s initial determination in July 2024 similarly confirmed the validity of the challenged patents, and also found that Innoscience infringed EPC’s foundational patent, U.S. Patent No. 8,350,294. The ITC’s final determination is subject to a 60-day Presidential review period, expiring on January 6, 2025.

LATEST NEWS / PRODUCT & TECHNOLOGY / SiC / WBGSTMicroelectronics Released an Advanced Galvanically Isolated Gate Drivers for IGBTs and SiC MOSFETs
November 7, 2024
2 Min ReadSTMicroelectronics’ STGAP3S family of gate drivers for silicon-carbide (SiC) and IGBT power switches combines ST’s latest robust galvanic isolation technology with optimized desaturation protection and flexible Miller-clamp architecture.
Featuring reinforced capacitive galvanic isolation between the gate-driving channel and the low-voltage control and interface circuitry, the STGAP3S withstands 9.6kV transient isolation voltage (VIOTM) with 200V/ns common-mode transient immunity (CMTI). With its state-of-the-art isolation, the STGAP3S enhances reliability in motor drives for industrial applications such as air conditioning, factory automation, and home appliances. The new drivers are also used in power and energy applications including charging stations, energy storage systems, power-factor correction (PFC), DC/DC converters, and solar inverters.
The STGAP3S product family includes different options with 10A and 6A current capability, each of them available with differentiated Under Voltage Lock-Out (UVLO) and desaturation intervention thresholds. This helps designers select the best device to match the performance of their chosen SiC MOSFET or IGBT power switches.
The Desaturation protection implements an overload and short-circuit protection for the external power switch providing the possibility to adjust the turn-off strategy using an external resistor to maximize the protection turn-off speed while avoiding excessive overvoltage spikes. The undervoltage-lockout protection prevents turn-on with insufficient drive voltage.
The driver’s integrated Miller Clamp architecture provides a pre-driver for an external N-channel MOSFET. Designers can thus leverage flexibility to select a suitable intervention speed that prevents induced turn-on and avoids cross conduction.
The available device variants allow a choice of 10A sink/source and 6A sink/source drive-current capability for optimum performance with the chosen power switch with desaturation-detection and UVLO thresholds optimized for IGBT or SiC technology. The fault conditions of desaturation, UVLO and overtemperature protection are notified with two dedicated open drain diagnostic pins.

ROHM Co., Ltd.’s financial report for the six months ending September 30, 2024, reveals a challenging period characterized by a decline in net sales and profitability. The company’s net sales dropped by 3.0% year-over-year to ¥232,022 million. This decline reflects a mix of robust demand in certain markets, such as automotive electronics, which increased sales in SiC power devices, and growth in the computer and storage sectors. However, these gains were offset by significant sales declines in the industrial equipment market.
Key financial metrics deteriorated, with ROHM reporting an operating loss of ¥974 million, a reversal from a profit of ¥29,833 million in the prior year. Factors influencing this loss include lower sales volumes, reduced production due to inventory adjustments, and higher costs associated with expanding SiC device production and adopting eight-inch wafers. The ordinary profit also declined to a loss of ¥129 million, impacted by foreign exchange losses. Profit attributable to shareholders dropped by 94.5% to ¥2,068 million, primarily due to reduced gains on securities sales.
ROHM’s EBITDA also saw a decrease, down 35.8% to ¥39,344 million. Segment-wise, integrated circuits and discrete semiconductor devices faced declines, with IC sales down 2.9% and segment profit down 54.8%. Power devices in the automotive sector performed well, but broader semiconductor device sales suffered from subdued demand in the industrial equipment sector. In contrast, modules and resistors segments showed marginal growth, supported by increased demand for smartphone sensor modules and high-power resistors for automotive applications.
Looking forward, ROHM expects continuing economic and industry challenges, such as slowing EV market growth, prolonged inventory adjustments in industrial equipment, and fluctuating consumer demand. As a result, ROHM has revised its forecast, projecting full-year sales to decrease by 3.8% to ¥450,000 million, alongside anticipated losses in operating profit and ordinary profit. The company plans to proceed with production adjustments, aiming for future alignment with customer demand, particularly in energy-efficient solutions and advanced power devices.
