VS-ST650C20L1

Scrs Overview

The VS-ST650C20L1 is a high-power Silicon Controlled Rectifier (SCR) manufactured by Vishay General Semiconductor. It features a clamp-on mounting style within the TO-200AC, B-PUK package. The device supports a rated repetitive off-state voltage of 2 kV and an RMS on-state current of 1557 A. It operates with a maximum on-state voltage of 2.18 V and maintains a holding current of 600 mA. The component functions reliably across a junction temperature range of -40°C to +125°C.

Scrs Feature Summary

High-current capability for heavy-duty power conversion
Robust mechanical design utilizing clamp-on mounting
Standard recovery characteristics for industrial switching

Scrs Applications

Industrial motor drives
High-power rectification systems
Resistive heating control applications

Scrs Procurement Notes

Verify the specific suffix L1 against official datasheets to confirm pinout and thermal interface compatibility. Ensure that the procurement channel provides original manufacturer documentation. Confirm that the TO-200AC B-PUK package matches the required mechanical constraints of the target assembly before finalizing orders.

Scrs Selection Notes

Select this component when designs require high RMS current handling exceeding standard discrete packages. The clamp-on configuration necessitates compatible hardware for secure installation. Evaluate thermal management requirements carefully due to the significant power dissipation associated with 1557 A operation at the specified on-state voltage.

Scrs Part Context

This SCR belongs to Vishay's high-power thyristor portfolio designed for demanding industrial environments. It complements other large-frame devices like the VS-ST300C20L1 but offers significantly higher current capacity. The TO-200AC form factor distinguishes it from smaller surface-mount or through-hole alternatives in the same product family.
