1200 V IGBT S series

Optimized for use in low-frequency (up to 8 kHz), hard-switching topologies, ST’s S series of 1200 V IGBTs feature the industry’s lowest V CE(sat) among 1200 V IGBTs currently on the market. Based on ST’s third-generation of trench-gate field-stop technology, they increase the efficiency of power supplies, welders and industrial motor drive applications thanks to the optimal trade-off between conduction and switching performance combined with outstanding robustness and EMI characteristics. Available in 15 A, 25 A and 40 A current ratings, they feature a 175°C maximum operating junction temperature, a 10 µs min short-circuit withstand time and a wide safe operating area (SOA).
