VS-ST180C18C1

Scrs Overview

The VS-ST180C18C1 is a silicon SCR module rated for 1.8 kV repetitive off-state voltage and 350 A average on-state current. It supports an RMS current of 660 A and a non-repetitive surge current of 5 kA at 50 Hz. The device features a maximum on-state voltage of 1.96 V, a gate trigger voltage of 3 V, and a holding current of 600 mA. Designed for clamp mount installation in TO-200AB (A-PUK) packages, it operates within a junction temperature range of -40°C to +125°C.

Scrs Feature Summary

• High-power thyristor construction utilizing silicon technology for robust industrial performance.
• Capable of handling significant non-repetitive surge currents up to 5 kA for fault tolerance.
• Engineered for secure mechanical attachment via clamp mounting style.

Scrs Applications

• Industrial motor drives requiring high current switching
• Resistive load control systems
• Inverter circuits in power conversion equipment

Scrs Procurement Notes

Verify the specific package variant and thermal interface requirements against your heatsink design before ordering. Confirm that the clamp mounting hardware matches the TO-200AB form factor. Check for any obsolescence notices or lifecycle changes directly with Vishay, as availability may vary. Ensure the gate drive circuitry can supply the required 3 V trigger voltage and 150 mA current. Validate that the system's peak reverse voltage does not exceed the 1.8 kV rating under all operating conditions.

Scrs Selection Notes

Select this component when applications demand high voltage blocking capability combined with substantial continuous current handling. The 1.8 kV rating suits medium-voltage AC control scenarios. Consider the 660 A RMS rating for sustained load operations. The TO-200AB package facilitates efficient heat dissipation through direct chassis mounting. Evaluate the 1.96 V on-state voltage impact on overall system efficiency and thermal management needs.
