VS-ST230C20C1

Scrs Overview

The VS-ST230C20C1 is a silicon controlled rectifier (SCR) manufactured by Vishay General Semiconductor - Diodes Division. It features a standard recovery type design housed in a TO-200AB package with A-PUK mounting configuration. The device supports a repetitive peak off-state voltage of 2 kV and an on-state RMS current rating of 780 A. Key electrical parameters include a maximum average on-state current of 410 A, a non-repetitive surge current of 4800 A at 50 Hz and 5000 A at 60 Hz, and a maximum on-state voltage of 1.69 V. Gate triggering requirements specify a maximum voltage of 3 V and a maximum current of 150 mA. The component operates within a temperature range of -40°C to 125°C.

Scrs Feature Summary

• High-voltage capability with a 2 kV repetitive peak off-state voltage rating for robust blocking performance.
• High-current handling capacity supporting 780 A RMS and significant non-repetitive surge currents up to 5000 A.
• Standard recovery characteristics suitable for general-purpose high-power switching applications.
• Clamp mount installation style utilizing the TO-200AB (A-PUK) package for secure mechanical attachment.

Scrs Applications

• Industrial motor drives requiring high voltage isolation and current handling.
• Power supply systems utilizing thyristor-based rectification or inversion.
• Static power switching circuits in heavy machinery or industrial automation.
• Resistive load control applications in high-power heating or lighting systems.

Scrs Procurement Notes

Verify part authenticity through authorized Vishay channels due to potential counterfeiting risks. Confirm package variant matches the specified A-PUK clamp mount configuration. Check for obsolescence status as distribution availability may be limited. Ensure thermal management solutions align with the 125°C maximum junction temperature rating. Validate gate drive circuitry compatibility with the 3 V / 150 mA maximum trigger specifications.

Scrs Selection Notes

Select this component when a 2 kV blocking voltage and 780 A RMS current capacity are required. Compare against lower voltage variants like the ST230C12C0 if system voltage permits reduction. Consider the TO-200AB form factor for existing clamp-mount infrastructure. Evaluate thermal resistance requirements based on the 410 A average current rating. Ensure the standard recovery speed meets the frequency constraints of the target application.
