1200V IGBTs with lowest saturation voltage VCE(sat)

New S-series 1200V IGBTs from STMicroelectronics are optimized for the lowest combined conduction and turn-off losses at switching frequencies up to 8kHz, to increase the power-conversion efficiency of uninterruptible power supplies, solar generators, welders, industrial motor drives, and similar equipment. The S series has the lowest saturation voltage (VCE(sat)) among 1200V IGBTs currently on the market, which ensures a lower voltage drop and minimizes power dissipation thereby simplifying thermal management. In addition, the positive VCE(sat) temperature coefficient, with tight distribution of parameters, simplifies paralleling of multiple devices for higher power requirements. Very low voltage overshoot and zero oscillation at turn-off allows simpler external circuitry and fewer components. With 10µs minimum short-circuit withstand time (at 150°C starting junction temperature), latch-up free operation, extended maximum operating junction temperature of 175°C, and wide Safe Operating Area (SOA), the new devices are extremely rugged and reliable. Ideal for use in the frequency range up to 8kHz, hard-switching topologies, the new S series featuring the third-generation trench-gate field-stop technology complements ST’s M-series and H-series 1200V IGBTs, which are designed for optimum efficiency at up to 20kHz and over 20kHz respectively. Together, these three series ...
