S4010VTP

Overview

The S4010VTP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse, designed for high-power switching applications. It features a 400 V repetitive peak off-state voltage and a 10 A RMS on-state current rating. The device utilizes a sensing gate structure to optimize triggering characteristics while maintaining robust performance under varying load conditions. Packaged in an isolated TO-220AB flange mount configuration, it provides efficient thermal dissipation through the case. This component belongs to the Sxx10xSx series, offering reliable operation in industrial power control circuits where precise gating and high voltage blocking are required.

Feature Summary

• Isolated TO-220AB flange mount package for secure mounting and effective heat sinking
• Sensing gate architecture for optimized trigger sensitivity and noise immunity
• High repetitive peak off-state voltage capability for robust blocking performance

Applications

• Industrial motor speed control systems
• AC power regulation and solid-state relays
• Lighting dimmer circuits for commercial fixtures

Procurement Notes

Verify the exact suffix against the manufacturer's official datasheet to confirm pinout orientation and specific electrical tolerances. Ensure the ordering part number matches the required voltage and current ratings for the target circuit design. Cross-reference with Littelfuse documentation to validate compliance with RoHS and REACH standards before finalizing procurement specifications.

Selection Notes

Select this SCR based on the requirement for a 400V blocking voltage and 10A continuous current handling capacity. The TO-220AB package necessitates adequate heatsinking infrastructure to manage thermal resistance during conduction. Evaluate the gate trigger current requirements against the driving circuit capabilities to ensure reliable turn-on without excessive gate power dissipation.

Part Context

This component is part of Littelfuse's Thyristors subcategory within the broader Power Control portfolio. It serves as a fundamental switching element in the Sxx10xSx family, which focuses on medium-power AC control solutions. The device complements other thyristor products by providing a standardized form factor for integration into modular power electronics assemblies.

Replacement Considerations

Consult Littelfuse substitution guides for equivalent SCRs with matching voltage and current ratings. Verify that alternative devices offer compatible gate trigger characteristics and thermal resistance values to maintain system performance without redesigning the cooling or drive circuitry.
