IRKL56/04A

SCRs - Modules Overview

The IRKL56/04A is a high-voltage silicon controlled rectifier module manufactured by Vishay General Semiconductor - Diodes Division. It features a single thyristor element with an integrated freewheeling diode, housed in the ADD-A-PAK GEN V package. The device supports a maximum repetitive peak reverse voltage of 400V and provides a continuous on-state current rating of 60A. Designed for industrial applications, it utilizes a thick copper baseplate for thermal management and offers isolated case connection.

SCRs - Modules Feature Summary

SCRs - Modules Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact electrical ratings and pinout configuration. Ensure the procurement channel sources genuine components from authorized distributors to prevent counterfeit parts. Confirm that the ADD-A-PAK mounting requirements align with the intended heatsink interface before finalizing orders.

SCRs - Modules Selection Notes

Select this component when a combined switching and freewheeling function is required in a compact form factor. The 400V rating suits lower voltage industrial AC applications. Verify that the thermal resistance characteristics of the ADD-A-PAK package meet the system's cooling requirements for the expected load currents.

SCRs - Modules Part Context

This part belongs to the IRKL series of thyristor modules designed for robust industrial performance. The series is characterized by its compatibility with standard TO-240AA footprints while offering improved isolation and thermal properties through the ADD-A-PAK GEN V technology.

SCRs - Modules Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic replacements may differ in gate trigger characteristics or thermal resistance.
