Rohm launches automotive MOSFET with wide-SOA
Rohm has developed the RS4P063BPHZG, a 100V MOSFET optimised for automotive safety functions and protection circuits. The new product is claimed to achieve 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 five 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, according to Rohm.
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.
