KYOTO, Japan<\/span>, Sept. 16, 2026<\/span> \/PRNewswire\/ — ROHM Co., Ltd. has developed the RS4P063BPHZG, a 100V MOSFET optimized for automotive safety functions and protection circuits. The new product achieves a Wide-SOA (Safe Operating Area) across a broad voltage range in the standard HPLF5060 (5060-size) package widely used in automotive applications. By incorporating a design that effectively suppresses secondary breakdown, it delivers approximately five times the SOA tolerance of standard equivalent-sized products under VDS=100V and PW=100 microseconds. This contributes to greater reliability in automotive applications subject to momentary high-power loads, including airbag inflator ignition circuits and seat belt pretensioner drive circuits.<\/p>\n

Adopting the standard 5060-size package also simplifies replacement evaluation with existing layouts, helping reduce the workload and costs associated with design changes.<\/p>\n

Recent advances in vehicle electrification are increasing demand for automotive systems that support higher voltages and currents. In particular, safety functions and protection circuits may experience momentary high-power loads during abnormal or emergency conditions, requiring the MOSFETs that drive them to provide high SOA capability.<\/p>\n

ROHM has established a strong track record of providing Wide-SOA products for AI servers and industrial power supplies, including products that have been selected as recommended components by a global cloud platform provider. The RS4P063BPHZG brings the same technologies and expertise to the automotive field.<\/p>\n

ROHM is developing automotive Wide-SOA MOSFETs in the HPLF8080 (8.0 x 8.0 mm) and TOLG (TO-Leaded with Gullwing, 9.9 x 11.7 mm) packages as well. Going forward, ROHM will continue expanding its portfolio for automotive safety functions and protection circuits.<\/p>\n

Application examples
– Airbag inflator ignition circuits
– Seat belt pretensioner drive circuits
– Pyro-fuse drive circuits for battery cutoff
– Other automotive safety functions and protection circuits exposed to short-duration high-current and high-voltage stress<\/p>\n
