Procurement Notes

Verify the specific suffix DH against official Powerex documentation to confirm exact pinout and mechanical tolerances. Ensure the procurement channel provides traceable source data matching the manufacturer's original specifications. Cross-reference the part number with the latest datasheet to confirm availability status and any recent product change notices that may affect form or fit dimensions.

Selection Notes

Select this component when system requirements demand a 900 V blocking voltage and continuous current handling near 1413 A. The T82 package offers a standardized footprint for mounting on compatible heatsinks. Consider the 150 mA gate trigger requirement for driver circuit design. Verify thermal management capabilities align with the device's dissipation characteristics under expected load conditions.

Part Context

This device belongs to the Powerex T82 series of silicon controlled rectifiers. The series is characterized by robust construction and high current ratings. These components are typically used in scenarios where reliable high-power switching is critical. The T82 package style is common in industrial power electronics for its efficient heat transfer properties.

Replacement Considerations

Direct substitutes must match the 900 V rating, 1413 A current capacity, and T82 package type. Verify gate trigger current compatibility to ensure proper drive signal levels. Confirm mechanical dimensions and terminal configurations for direct replacement without PCB modifications.
