S4010L

Overview

The S4010L is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse, designed for high-current power control applications. It features a 400V repetitive peak reverse voltage and a 400V repetitive peak forward blocking voltage, ensuring reliable operation in demanding electrical environments. The device supports a maximum RMS on-state current of 10A and can handle surge currents up to 150A. Packaged in an isolated TO-220AB flange mount configuration with three pins, it facilitates efficient heat dissipation. Key electrical characteristics include a low holding current of 50mA and a gate trigger current of 200mA, providing stable latching performance.

Feature Summary

• Isolated flange mount construction for secure mounting and thermal management
• High surge current capability for robust transient handling
• Sensitive gate triggering for efficient control circuitry

Applications

• Industrial motor speed control systems
• AC power regulation circuits
• Lighting dimmer controls

Procurement Notes

Verify the specific suffix against the official Littelfuse datasheet to confirm exact electrical tolerances and package variations. Ensure the procurement channel provides authentic components with traceable documentation. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and technical specifications before finalizing orders.

Selection Notes

Select this component based on its 10A RMS current rating and 400V voltage blocking capabilities. Consider the TO-220AB package for adequate thermal dissipation in high-power designs. Evaluate the gate trigger requirements to ensure compatibility with the driving circuit's output current. Confirm that the isolated case connection meets the system's grounding and safety isolation needs.

Part Context

This SCR belongs to the Sxx10xSx series from Littelfuse, which focuses on general-purpose thyristors for power control. The series offers various voltage ratings while maintaining consistent current handling and packaging standards. This specific model represents a standard variant within the lineup, balancing performance and cost for widespread industrial use.

Replacement Considerations

Consult Littelfuse official substitution guides or equivalent manufacturer cross-reference lists for verified alternatives. Ensure any substitute matches the 10A current, 400V voltage, and TO-220AB package dimensions. Verify identical electrical parameters such as gate trigger current and holding current to maintain circuit functionality.
