Overview
The Littelfuse S4010RS2 is a Silicon Controlled Rectifier (SCR) belonging to the Sxx10xSx series, designed for high-power switching applications. It features a TO-220AB flange mount package with three terminals and an anode-connected case configuration. The device supports a maximum repetitive peak off-state voltage of 400 V and handles a maximum RMS on-state current of 10 A. Key electrical characteristics include a maximum DC gate trigger current of 0.2 mA, a holding current of 6 mA, and a non-repetitive peak surge current capability of 100 A. The component operates within a temperature range of -40 °C to 100 °C.
Feature Summary
- Sensitive gate triggering requiring low control power
- Robust thermal management via flange mount design
- High surge current handling capacity
Applications
- Industrial motor speed control systems
- AC power regulation circuits
- Lighting dimmer controls
Procurement Notes
Verify the specific suffix against official Littelfuse documentation to confirm exact pinout and thermal interface specifications. Ensure the procurement channel provides valid RoHS compliance certificates. Confirm that the TO-220AB package dimensions match the target PCB footprint requirements before finalizing orders.
Selection Notes
Select this component when a 400 V blocking voltage and 10 A continuous current rating are required in a standard through-hole package. The sensitive gate characteristic simplifies drive circuit design by reducing the necessary trigger current. Evaluate thermal dissipation needs carefully, as the TO-220AB package requires adequate heatsinking for sustained operation at rated currents.
Part Context
This SCR is part of Littelfuse's general-purpose thyristor portfolio, specifically the Sxx10xSx family. These devices are engineered for reliable performance in industrial environments where robust switching and moderate voltage ratings are essential. The product line emphasizes durability and consistent electrical characteristics across varying operating temperatures.
Replacement Considerations
Consult Littelfuse cross-reference guides for verified equivalents. Ensure any substitute maintains identical voltage, current, and package specifications to guarantee mechanical and electrical compatibility.
