IRKT42/08A

Overview

The IRKT42/08A is a dual Silicon Controlled Rectifier (SCR) module manufactured by Vishay General Semiconductor - Diodes Division. It features an Add-A-Pak (3 + 4) package designed for base mounting applications. The device supports a maximum repetitive peak off-state voltage of 800 V and a maximum average on-state current of 60 A. The root mean square on-state current rating is specified at 95 A. The module operates within a junction temperature range of -40°C to 125°C.

Feature Summary

Dual SCR configuration with common cathode structure
Add-A-Pak (3 + 4) housing for efficient thermal management
High surge current capability for robust circuit protection

Applications

Industrial motor control systems
Power supply regulation circuits
AC power switching applications

Procurement Notes

Verify the specific suffix designation against official Vishay documentation, as variations may exist. Confirm that the Add-A-Pak pinout matches the target PCB layout requirements. Ensure the procurement channel provides valid traceability records for this discontinued component series. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit sources.

Selection Notes

Select this component when a dual SCR solution in a compact Add-A-Pak form factor is required. The 800 V rating suits medium-voltage AC applications. Evaluate the 95 A RMS current capacity against the load requirements. Consider the 125°C maximum junction temperature for high-thermal environments. Verify compatibility with existing gate drive circuits given the specified trigger parameters.

Part Context

This component belongs to the IRKU56 family of SCR modules from Vishay. These devices are engineered for high-power industrial applications requiring reliable phase control. The Add-A-Pak packaging facilitates direct mounting to heatsinks, simplifying thermal design in power electronics assemblies.
