IRKT71/08A

Overview

The IRKT71/08A is a Silicon Controlled Rectifier (SCR) module manufactured by Vishay General Semiconductor. It features a series-connected, center-tap configuration with two elements housed in an ADD-A-PAK-7 package compatible with TO-240AA standards. The device supports a maximum repetitive peak reverse voltage of 800V and an RMS on-state current of 117.75A. Key electrical characteristics include a maximum DC gate trigger current of 150 mA and a maximum holding current of 200 mA. It operates within a junction temperature range of -40°C to 125°C.

Feature Summary

Series-connected, center-tap configuration for high-voltage applications
Flange mount design with isolated case connection
Compliant with RoHS directives

Applications

High voltage power conversion systems
Industrial motor control drives
Static power switching circuits

Procurement Notes

Verify the specific suffix designation against official Vishay documentation to confirm lead-free status and exact pinout compatibility. Ensure the procurement source provides valid UL recognition evidence as specified in the component datasheet. Confirm that the ADD-A-PAK-7 mechanical dimensions match the target heatsink interface requirements before integration into the final assembly.

Selection Notes

Select this component for applications requiring robust high-current handling in a standard industrial package. The center-tap configuration facilitates specific bridge rectifier or phase-control topologies. Verify thermal management capabilities align with the 125°C maximum junction temperature limit. Ensure gate drive circuitry can supply the required 150 mA trigger current reliably under all operating conditions.

Part Context

This part belongs to the IRK series of thyristor modules from Vishay, designed for heavy-duty industrial use. The ADD-A-PAK family utilizes Direct Bonded Copper substrates for superior thermal performance. These modules are engineered for easy mounting on heatsinks while providing high surge capability and reliable operation in demanding power electronics environments.
