IRKT91/04A

Overview

The IRKT91/04A is a silicon controlled rectifier (SCR) module manufactured by Vishay General Semiconductor. It features a TO-240AA (ADD-A-PAK) flange mount package with three terminals and an isolated case connection. The device is rated for a maximum repetitive peak reverse voltage of 400 V and a continuous on-state current of 95 A. It supports a non-repetitive peak forward surge current of 2094 A. The component operates within a junction temperature range of -40 °C to +125 °C.

Feature Summary

High-power SCR configuration in an insulated flange-mount package
Robust surge current handling capability for industrial loads
Isolated case design for simplified thermal management

Applications

Industrial motor drives
Resistive heating control systems
Power supply circuits

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact electrical ratings and compliance status. Ensure the procurement channel provides valid traceability for the ADD-A-PAK package type. Confirm that the requested units match the specified 400V and 95A parameters before finalizing acquisition.

Selection Notes

Select this component when a high-current, low-voltage SCR is required in an insulated module format. The TO-240AA package facilitates direct heatsink mounting. Verify that the 400V rating aligns with the system's peak reverse voltage requirements and that the 95A continuous current meets the load demands under expected thermal conditions.

Part Context

This part belongs to the Vishay IRKT series of power SCRs. These modules are designed for general-purpose industrial applications requiring reliable phase control. The ADD-A-PAK packaging standardizes thermal interface dimensions for common heatsink compatibility within power electronics assemblies.

Replacement Considerations

Consult official Vishay cross-reference lists for verified substitutes. Ensure any replacement maintains the TO-240AA footprint, 400V rating, and 95A current capacity without altering the isolation characteristics.
