650 V, 75 A IGBT in TO-247 advanced isolation package Hard-switching 650 V, 75 A TRENCHSTOP™ 5 S5 IGBT discrete in TO247 advanced isolation package. This IGBT technology addresses applications switching between 10 kHz and 40 kHz. This package eliminates the need of isolation material and enables high power density, the best thermal performance and the lowest cooling effort thanks to an effective and reliable thermal path from the IGBT die to the heatsink.
