ROHM Semiconductor Unveils High-Reliability MOSFET for Automotive Safety Systems
Event summary
- ROHM Semiconductor launched the RS4P063BPHZG, a 100V MOSFET with industry-leading Wide-SOA for automotive safety functions.
- The MOSFET achieves approximately 5 times the SOA tolerance of standard equivalent-sized products under VDS=100V and PW=100μs.
- Mass production began in June 2026, with the product available through distributors like DigiKey and Farnell.
- ROHM is developing additional automotive Wide-SOA MOSFETs in HPLF8080 and TOLG packages.
The big picture
ROHM Semiconductor's new MOSFET addresses the growing demand for high-reliability components in automotive safety systems, particularly as vehicle electrification increases the need for higher voltage and current capabilities. The product leverages ROHM's expertise in Wide-SOA technologies, previously applied in AI servers and industrial power supplies, to enhance safety in critical automotive functions. This launch positions ROHM as a key player in the automotive semiconductor market, with potential implications for safety standards and component design.
