Procurement Notes

Verify the specific suffix codes against official Powerex documentation to confirm exact electrical tolerances and packaging variations. Ensure compatibility with existing thermal management solutions due to the high current rating. Cross-reference the T82 package dimensions with PCB layout requirements before finalizing procurement orders to prevent assembly issues.

Selection Notes

Select this component when applications demand high RMS current capacity alongside a 900 V blocking voltage. The T82 package offers a balance of thermal dissipation and mounting simplicity for industrial enclosures. Consider the 120 mA gate trigger requirement when designing the driving circuitry to ensure reliable turn-on under all operating conditions.

Part Context

This SCR belongs to the Powerex T82 series, which provides standardized disk button packages for high-power thyristor applications. The series is widely recognized in industrial sectors for its reliability and consistent performance under extreme electrical stress.
