ROHM Develops Four Types of 1200V Withstand Voltage IGBTs for Automotive Compliant with AEC-Q101 Automotive Reliability Standard
Published2019.05.13 15:42| Low conduction loss, contributes to application miniaturization
| Short-circuit withstand time guaranteed at 10μsec
ROHM announced on the 10th that it has newly developed four types of 1200V withstand voltage IGBTs, the 'RGS series,' that comply with the automotive reliability standard AEC-Q101.
The electrification of automobiles is accelerating. In conventional engine-powered vehicles, the compressor is powered by the engine, but with the increase in electric vehicles, the electrification of compressors is also being promoted. Furthermore, while engine heat has traditionally been used for vehicle heating, there is a growing demand for systems that utilize PTC heaters to circulate hot water for heating.
IGBTs are the mainstream semiconductors used in the inverter and switch circuits of these applications due to the low driving frequency. In particular, for electric vehicles, high efficiency is required because the power consumption of the compressor and heater affects the driving range.
Automakers are increasing the capacity of installed batteries to extend the driving range of electric vehicles. In particular, in Europe, as the number of cases equipped with high-voltage (800V) batteries increases, there is a growing need for power devices with even higher voltage resistance and lower loss. Consequently, in addition to existing 650V voltage resistance IGBTs, there is also a rising demand for 1200V voltage resistance IGBTs.
ROHM has developed a 1200V withstand voltage product compliant with the automotive reliability standard AEC-Q101, expanding its lineup along with the 650V withstand voltage product.
The RGS series achieves low conduction loss (Vce(sat.)) and contributes to the miniaturization and high efficiency of applications. In addition, the short-circuit withstand time of the 1200V withstand voltage product is guaranteed to be 10μsec (Tj=25℃), so it can be used with confidence even in automotive equipment where high reliability is required.
With the release of four 1200V withstand voltage products, ROHM now offers a total of 11 product types, including 650V withstand voltage products. Since ROHM offers both standalone IGBTs and types with integrated freewheeling diodes, customers can select the optimal device.
The RGS series began mass production in January 2019 with a production capacity of 1 million units per month.

ROHM Adds 10 SiC MOSFETs to its SCT3xxxxxHR Series, Compliant with Automotive Device Reliability Standards.
Recently, extending the short driving range of electric vehicles has emerged as one of the major challenges. To extend the driving range, battery capacity must be increased, which also requires shorter charging times. Rohm has newly added 10 products to its SiC MOSFET 'SCT3xxxxxHR series' that complies with the automotive equipment reliability standard AEC-Q101 for vehicle chargers and DC/DC converters. With this lineup expansion, Rohm has established a comprehensive lineup encompassing a total of 34 products combining SiC SBD and SiC MOSFET.

ROHM Launches 1700V SiC MOS Embedded AC/DC Converter IC Family for High-Power Industrial Equipment
Rohm has developed the BM2SCQ12xT-LBZ, an AC/DC converter IC with an embedded 1700V withstand voltage SiC MOSFET for industrial equipment such as high-power general-purpose inverters and AC servos, industrial air conditioners, and street lights. The BM2SCQ12xT-LBZ incorporates an embedded SiC MOSFET, enabling simple development of low-power AC/DC converters by resolving design challenges that arise when using discrete components. Through a control circuit optimized for auxiliary power supplies in industrial equipment and single-package integration of the SiC MOSFET, the product simultaneously achieves significant reduction in component count compared to conventional configurations, reduced risk of component failure, and reduced development effort required for SiC MOSFET adoption.
