Overview
The Littelfuse S4010VS2 is a silicon-controlled rectifier (SCR) designed for high-power switching applications. It features a 400V repetitive peak off-state voltage and a 10A average on-state current rating. The device utilizes a TO-220AB flange mount package, facilitating efficient thermal management through direct heatsink attachment. Key electrical characteristics include a maximum DC gate trigger current of 200µA and a holding current of 6mA. The component supports a non-repetitive peak on-state current of 100A and offers a critical rate of rise of off-state voltage of 250V/µs. Operating temperatures range from -40°C to +125°C junction temperature.
Feature Summary
- Robust thermal performance enabled by the TO-220AB flange mount package design for direct heatsinking
- High surge current capability suitable for demanding industrial power control loads
- Low gate trigger current requirement for efficient drive circuit integration
Applications
- Industrial motor speed control systems
- Solid-state relay output stages
- AC power regulation circuits
Procurement Notes
Verify the specific suffix 'VS2' against the manufacturer's official datasheet to confirm pinout configuration and thermal interface specifications. Ensure the ordering documentation explicitly references Littelfuse as the source to avoid counterfeit components. Cross-reference the part number with the latest product change notifications to verify material compliance and manufacturing origin details prior to procurement.
Selection Notes
Select this component when a 400V blocking voltage and 10A continuous current capacity are required in a standard TO-220 form factor. Evaluate the thermal resistance requirements of the application to ensure adequate heatsinking for the flange mount package. Confirm that the gate trigger characteristics align with the available drive voltage and current limits of the control circuitry.
Part Context
This SCR belongs to the Sxx10xSx series, which provides standardized power switching solutions for general industrial use. The series is characterized by reliable thyristor technology optimized for cost-effective power control. The S4010VS2 variant specifically addresses applications requiring moderate voltage ratings with robust current handling capabilities in a widely used through-hole package format.
Replacement Considerations
Consult the Littelfuse replacement guide for equivalent SCRs with matching voltage and current ratings. Verify that alternative packages maintain compatible mounting dimensions and thermal dissipation characteristics. Ensure gate trigger parameters of substitute parts fall within the acceptable range of the existing drive circuit design.
