1.2 kV SCR for automotive power stages
The Vishay VS-50TPS12LHM3 is a standard-recovery SCR rated for 1.2 kV off-state voltage and 50 A average (79 A RMS) on-state current, housed in a TO-247AD through-hole package.
Surge capability and gate drive margin
Non-repetitive surge current is rated 630 A at 50 Hz, which covers the inrush from a capacitor bank or motor start without additional snubber derating. Gate trigger is specified at 100 mA max (1.5 V max), so a standard 5 V logic-level drive through a series resistor will fire it reliably across temperature. Hold current of 300 mA means the SCR stays latched once triggered under normal load; if the load current dips below that threshold during a fault, the device will commutate off.
ROHS3 compliant.
