Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to ensure correct voltage and current ratings. Confirm RoHS compliance status if required by project specifications. Check for alternate part numbers such as VSKH136/08PBF which may share similar characteristics but differ in exact parameter tolerances or packaging details. Ensure sourcing channels provide genuine factory-sealed units with valid date codes to guarantee performance reliability.

Selection Notes

Select this component when an 800V rating and 135A continuous current capacity are required in a compact form factor. The INT-A-PAK package offers a balance between thermal performance and mounting simplicity via screw terminals. Consider the operating temperature range and gate trigger requirements to ensure compatibility with the control circuitry. Evaluate space constraints and heat dissipation needs relative to the module's physical dimensions and weight.

Part Context

This SCR module belongs to Vishay's high-current discrete semiconductor line, often utilized in demanding power conversion environments. It is part of a family that includes variants with different voltage ratings, such as the IRKL136/14 for 1400V applications. The series is characterized by robust construction and reliable switching performance for industrial-grade equipment.

Replacement Considerations

The VSKH136/08PBF is a documented alternative with similar 800V and 135A specifications. Verify pinout compatibility and thermal resistance values before substitution. Other variants in the IRKL series offer different voltage ratings and should be evaluated based on specific circuit requirements.
