IRKT42/12A

Overview

The IRKT42/12A is a Silicon Controlled Rectifier (SCR) module manufactured by Vishay General Semiconductor - Diodes Division. It utilizes the ADD-A-PAK package and is rated for a repetitive peak reverse voltage of 1200 V and an on-state current of 100 A.

Feature Summary

• High power density design in compact ADD-A-K package
• Robust silicon controlled rectifier construction
• Engineered for high voltage industrial applications

Applications

• Industrial motor drives
• Power supply systems
• Welding equipment

Procurement Notes

Verify the specific suffix '12A' to confirm the 1200 V rating, as the base IRKT42 series includes variants with different voltage ratings such as 800 V and 1000 V. Ensure the procurement documentation explicitly references the Vishay datasheet for the IRKT42 series to validate electrical characteristics and mechanical dimensions before integration.

Selection Notes

Select this component when a 100 A SCR module with a 1200 V blocking capability is required. The ADD-A-PAK form factor offers efficient thermal management for high-current applications. Consider the gate trigger requirements and thermal resistance specifications relative to the system's cooling infrastructure to ensure reliable operation under load.

Part Context

This device belongs to the IRKT42 family of SCR modules from Vishay. These components are designed for demanding power electronics environments where high current handling and voltage isolation are critical. The ADD-A-PAK packaging provides a standardized solution for mounting and thermal dissipation in industrial power conversion systems.

Replacement Considerations

Direct substitutes within the same voltage and current class include the IRKT42/10A (1000 V) or IRKT42/16A (1600 V), provided the voltage margin allows. Verify pinout compatibility and thermal interface requirements when considering alternative manufacturers or series.
