</div>Santa Clara, CA and Kyoto, Japan, Sept. 15, 2026 <a href="https://www.globenewswire.com" target="_blank">(GLOBE NEWSWIRE)</a> -- <a href="https://www.globenewswire.com/Tracker?data=UvQruuH5mhF_LgzeDpWMvIW9T2SWJSWB20N48x_2UaPOhBuoorNpoEsFhbR-e92nMAGnZ4ID3bpV8UDC9zbFuaQdKMccAg6a1493ZgnZH4w=" rel="nofollow" target="_blank" title="ROHM Semiconductor">ROHM Semiconductor</a> today announced it has developed the<a href="https://www.globenewswire.com/Tracker?data=bG_zUJKY7innl08N_2mvcy2jvMqwlDeCEbKFhTRC7MZqAHHVu96Siy7Tl0rimcQlOUa9luwo6CO8GJUzsMMBBppchNR5sykZKQNLEDbiSOKfffTi1U7512yZgf4Y_OEvrHvsL8bc1hUfSe9m51vlUhDD5b-CZiza6Ogti9SfP3Y=" rel="nofollow" target="_blank" title="RS4P063BPHZG"> RS4P063BPHZG</a>, a 100V MOSFET optimized for automotive safety functions and protection circuits. The new product achieves industry-leading* 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 5 times the SOA tolerance of standard equivalent-sized products under VDS=100V and PW=100μs. This contributes to greater reliability in automotive applications subject to momentary high-power loads, including airbag inflator ignition circuits and seatbelt pretensioner drive circuits. Adopting the standard 5060-size package also simplifies replacement evaluation with existing layouts, helping reduce the workload and costs associated with design changes. Recent advances in vehicle electrification are increasing the 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. 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. Mass production began in June 2026. The product is available for purchase through online distributors such as <a href="https://www.globenewswire.com/Tracker?data=ae_kcYXO9A-c7Xb6w4slf5n00OR76NOXLGN7DwE8W7hX8azEguSC1s4khzRM1ogiYtEbizCCK19EjGwR61lBuCrApUDtkLfMFkG39VZhEP_OFRCks9o9AdZgLIYdriDXYJ1e1LrgO1xqZQZgxX6WgHk7gpwJEnRzB48W5MeoPgQFAGZ2tdnHBN_vxH-U2p3wrqXuj2pN4Ku6R7EhcHBvfyHJPYQt_w4fhNUZbjAKgcg=" rel="nofollow" target="_blank" title="DigiKey">DigiKey</a> and <a href="https://www.globenewswire.com/Tracker?data=zfpoEwsUdDHVfGYpBdB0PdrPVOjxD1JjebZo7ssgSMeZhAcV3QxHeqhD6MnG7GGoGqJOe_mWy_xywKhlqXnj_cloZ1OONrcl2JovWwWl8eoHcnEE2PrrunMF9lZIJ0x2ZTCanUPN31GBUXrRqr0A1avAaJ3GKWbcW0O5ASFvSqie7IyfdT2yx9ZFkt-ZbnW2" rel="nofollow" target="_blank" title="Farnell">Farnell</a>. Design models and development tools are also offered on ROHM’s website to support rapid circuit evaluation. ROHM is developing automotive Wide-SOA MOSFETs in the HPLF8080 (8.0 × 8.0mm) and TOLG (TO-Leaded with Gullwing, 9.9 × 11.7mm) packages as well. Going forward, ROHM will continue expanding its portfolio for automotive safety functions and protection circuits.
