Procurement Notes
Verify the manufacturer designation carefully, as the model prefix may vary between Vishay General Semiconductor and International Rectifier (Infineon). Confirm that the specific datasheet aligns with the required electrical ratings and mechanical dimensions before finalizing procurement specifications.
Selection Notes
Select this component for applications requiring high current handling in a compact form factor. Ensure the cooling system design accommodates the thermal resistance of the flange mount package. Verify that the gate drive circuitry can supply the necessary trigger current to ensure reliable switching under all operating conditions.
Part Context
This component belongs to the family of high-power silicon controlled rectifiers designed for industrial power conversion. These modules are engineered to handle significant electrical loads while maintaining stability in demanding environments. They serve as critical switching elements in systems where robust performance and efficient heat dissipation are essential requirements.
Replacement Considerations
Cross-reference part numbers such as VS-VSKH136/08PBF or IRKK136-08CKNPBF for potential substitutes. Verify that any replacement matches the original voltage, current, and mounting specifications exactly.
