IRKT142/14

Overview

The IRKT142/14 is a silicon controlled rectifier (SCR) module manufactured by Vishay General Semiconductor - Diodes Division. It features a rated repetitive off-state voltage of 1400 V and an RMS on-state current of 140 A. The device utilizes the INT-A-PAK package for screw mounting, supporting a non-repetitive peak on-state current of 4.5 kA. Operating within a junction temperature range of -40°C to +125°C, it includes specific gate trigger requirements with a maximum holding current of 200 mA.

Feature Summary

• High-power SCR module design utilizing INT-A-PAK packaging for robust thermal management and mechanical stability in industrial applications.

Applications

• Industrial motor control systems
• Power supply circuits requiring high voltage blocking
• General purpose thyristor applications

Procurement Notes

Verify the exact part number against official Vishay documentation, as datasheets may list equivalent or superseded part numbers such as VS-VSKT142/14PBF. Confirm that the INT-A-PAK package dimensions and mounting hole patterns match your mechanical design constraints before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring a 1400 V blocking capability and 140 A continuous current handling in a compact screw-mount form factor. Ensure the gate drive circuitry can provide sufficient trigger current and voltage while respecting the specified holding current limits for reliable latching operation.
