Product details

Fast recovery characteristics for high-frequency switching

The STTH12004TV1 is a dual-diode module in the ISOTOP package, configured as two independent 60 A diodes with a 400 V reverse voltage rating. The forward voltage drop is 1.2 V at 60 A per diode, a typical figure for a 400 V silicon fast-recovery diode at this current level.

ISOTOP chassis-mount package — mechanical fit

The ISOTOP package (ST's ISOTOP® variant) is a bolted, chassis-mount module designed for high-current, high-dissipation applications. It does not solder to a PCB; instead it mounts directly to a heatsink with M4 or M5 screws, and the power terminals accept ring lugs or bus bars. Reverse leakage is 50 µA at 400 V, which is typical for a 400 V fast-recovery diode at room temperature.
