Procurement Notes

Verify the specific suffix or variant code against the manufacturer's official datasheet to ensure compatibility with required voltage and current ratings. Confirm that the Int-A-Pak package dimensions match the intended heatsink and mounting hardware specifications. Check for any recent obsolescence notices or alternative part recommendations from Vishay before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring high voltage blocking capabilities combined with substantial continuous current handling. Ensure the thermal design accounts for the specified operating temperature range and on-state voltage drop. Verify that the gate drive circuitry can supply the necessary trigger current and voltage without exceeding maximum ratings during transient conditions.
