Scrs datasheet and documents for VS-22RIA40

VS-22RIA40

Scrs Overview

The VS-22RIA40 is a medium power thyristor manufactured by Vishay General Semiconductor - Diodes Division. It features a stud mount configuration with two pins and operates within a junction temperature range of -55°C to 175°C. Key electrical ratings include a maximum DC gate trigger current of 60 mA, a maximum DC gate trigger voltage of 2 V, and a maximum holding current of 130 mA. The device supports a typical average on-state current (IT(AV)) ranging from 10 A to 120 A depending on case temperature, with a corresponding RMS current of 140 A to 160 A. It exhibits a nominal circuit commutation turn-off time of 110 µs and can withstand a non-repetitive peak on-state current of 420 A.

Scrs Feature Summary

Improved glass passivation for high reliability and exceptional stability at high temperatures
High di/dt and dv/dt capabilities
Low thermal resistance design

Scrs Applications

Medium power switching
Phase control applications
Military, aerospace, and other high-reliability requirements

Scrs Procurement Notes

Verify the specific suffix or variant against official Vishay documentation to confirm exact current ratings and thread metrics. Ensure the procurement specification matches the required IT(AV) and V DRM/V RRM levels. Confirm compliance with any applicable military or aerospace standards if the application demands high-reliability certification. Cross-reference the package details to ensure compatibility with the intended mounting hardware.

Scrs Selection Notes

Select this component for applications requiring robust phase control or medium power switching with high thermal stability. Consider the stud mount package for efficient heat dissipation in high-current scenarios. Evaluate the 110 µs turn-off time against the circuit frequency requirements. Verify that the 420 A surge current capability meets the system's transient load demands.
