IRKH56/14A

SCRs - Modules Overview

The IRKH56/14A is a silicon controlled rectifier (SCR) module manufactured by Vishay General Semiconductor - Diodes Division. It features a Double Low Inductance SCR (LOSCR) configuration with a built-in diode, housed in an ADD-A-PAK flange mount package. The device has a maximum repetitive peak off-state voltage of 1400 V and a maximum on-state current of 60 A. Key electrical parameters include a maximum DC gate trigger current of 150 mA, a maximum DC gate trigger voltage of 4 V, and a maximum holding current of 200 mA. The component supports a non-repetitive peak on-state current of 1520 A and operates within a junction temperature range up to 150 °C.

SCRs - Modules Procurement Notes

Verify the specific suffix designation against official Vishay documentation to confirm exact voltage ratings and pinout configurations, as variations exist within the family. Ensure compatibility with mounting hardware for the ADD-A-Pak package. Confirm compliance requirements such as UL approval status if required for your specific end-use application before finalizing procurement.

SCRs - Modules Selection Notes

Select this component when high voltage blocking capability and robust surge handling are required in a compact flange-mount form factor. The integrated diode feature simplifies design by eliminating the need for external freewheeling components. Consider the thermal resistance characteristics of the ADD-A-Pak package for heatsink selection to maintain safe operating temperatures under continuous load conditions.
