Scrs Procurement Notes

Verify the specific datasheet revision and mechanical drawing dimensions against your design requirements before finalizing procurement. Confirm that the thermal management solution aligns with the component's junction-to-case thermal resistance specifications to ensure safe operating temperatures under load conditions.

Scrs Selection Notes

Select this component when designing circuits requiring moderate voltage blocking up to 400 V combined with substantial continuous current capacity around 110 A. Ensure the gate drive circuitry provides sufficient trigger current to reliably turn on the SCR within the specified timeframes while maintaining adequate noise immunity during off-states.

Scrs Part Context

This part belongs to Vishay's general-purpose SCR lineup, typically housed in standardized modules like the MT-K or similar base-mounted packages. These devices are engineered for durability in demanding environments, offering consistent performance characteristics across varying temperature ranges typical of industrial electronics manufacturing.

Scrs Replacement Considerations

Consult official Vishay substitution guides for compatible alternatives. Verify that any substitute matches the 400 V voltage rating and 110 A current capacity while maintaining identical pinout configurations and mounting hole patterns to avoid redesigning the PCB or heatsink assembly.
