S2010LS2

Overview

The Littelfuse S2010LS2 is a sensitive silicon-controlled rectifier (SCR) designed for half-wave unidirectional gate-controlled rectification. It features a TO-220 isolated package with an electrically isolated mounting tab, enabling low-cost assembly and convenient packaging techniques. The device provides overcurrent protection and switching capabilities in power control applications. Key electrical specifications include a maximum on-state current of 10 A, a repetitive peak off-state voltage rating of 200 V, and a DC gate trigger current of 200 µA. The component utilizes glass-passivated junctions to ensure long-term reliability and parameter stability against junction contamination.

Procurement Notes

Verify the specific part number S2010LS2 against official Littelfuse documentation to confirm the exact voltage and current ratings before procurement. Ensure that the required isolation voltage and thermal management capabilities align with the design specifications. Confirm compliance with RoHS standards if environmental regulations apply to the final assembly. Cross-reference the datasheet test conditions with actual operating environments to validate performance margins.

Selection Notes

Select this component when a high-current SCR with electrical isolation is required for sensitive circuitry. The 200 V rating suits lower voltage AC applications, while the 200 µA gate sensitivity allows for efficient triggering from low-power control signals. Consider the thermal resistance and maximum allowable case temperature curves for heat dissipation planning. Verify that the peak surge current capacity meets the system's fault requirements.

Part Context

This device belongs to the Teccor line of sensitive SCRs, which complement Littelfuse's broader power SCR portfolio. The product range covers ratings from 0.8 A to 10 A with voltages up to 600 V. The S2010LS2 specifically represents the 10 A class within the isolated TO-220 family, offering a robust solution for industrial and commercial power control needs where galvanic isolation between the gate drive and the load is necessary.

Replacement Considerations

Direct replacements must match the 10 A current rating, 200 V blocking voltage, and TO-220 isolated package form factor. Verify that any substitute maintains equivalent gate trigger current characteristics and thermal performance. Check for compatible lead configurations and isolation voltage ratings to ensure seamless integration into existing PCB layouts without redesign.
