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.
Feature Summary
- Double LOSCR configuration with integrated freewheeling diode for reduced circuit complexity
- Flange mount construction with isolated case connection for efficient thermal management
- High surge current capability suitable for demanding power switching applications
Applications
- Industrial motor drives and control systems
- High-power AC/DC conversion circuits
- Static power switching and inverters
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.
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.
Part Context
This part belongs to Vishay's series of high-power SCR modules designed for industrial applications. The ADD-A-Pak packaging provides a standardized mechanical interface for easy integration into power electronics assemblies. These devices are engineered for reliability in environments requiring precise control of high currents and voltages.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Vishay technical support or authorized distributors for verified cross-reference data before attempting substitution.
