VS-ST333C08LFM0

Scrs Overview

The VS-ST333C08LFM0 is a silicon controlled rectifier (SCR) from Vishay General Semiconductor. It features an 800 V off-state voltage rating and supports high current applications with a 1435 A RMS on-state current capability in clamp-on configurations. The device utilizes a TO-200AB (E-Puk) package designed for chassis mounting. Key electrical parameters include a maximum gate trigger voltage of 3 V and a maximum gate trigger current of 200 mA. This component is engineered for robust performance in industrial power control environments requiring reliable phase control.

Scrs Feature Summary

• High current handling capacity suitable for heavy-duty industrial power applications
• Robust mechanical design utilizing the TO-200AB E-Puk clamp-on package for secure chassis mounting
• Standard recovery characteristics optimized for reliable phase control operations

Scrs Applications

• Industrial motor speed control systems
• High-power heating element regulation
• Static VAR compensators

Scrs Procurement Notes

Verify the specific datasheet version to confirm exact thermal resistance values and detailed mechanical dimensions prior to integration. Ensure that the procurement channel provides official documentation matching the VS-ST333C08LFM0 designation. Confirm compatibility with existing cooling infrastructure due to the high current ratings associated with this component series.

Scrs Selection Notes

Select this component when an 800 V blocking voltage and high RMS current capacity are required for phase control circuits. The clamp-on mounting style necessitates compatible hardware for installation. Evaluate thermal management requirements carefully, as the TO-200AB package relies on effective heat dissipation through the chassis mount interface for sustained operation at rated currents.

Scrs Part Context

This SCR belongs to the VS-ST333C series, which focuses on high-current thyristor solutions. The series is characterized by its ability to handle significant power loads in discrete semiconductor form factors. The specific model integrates standard recovery properties, distinguishing it from ultra-fast variants, making it suitable for general-purpose industrial AC power control tasks rather than high-frequency switching applications.

Scrs Replacement Considerations

Cross-reference with other Vishay VS-ST333C series variants offering different voltage ratings or package options if system requirements change. Verify pinout and mounting hole patterns match when substituting with components from other manufacturers to ensure mechanical and electrical compatibility without redesigning the chassis interface.
