Overview
The Littelfuse S4004DS1RP is a silicon-controlled rectifier (SCR) designed for surface-mount applications. It features a rated repetitive off-state voltage of 400 V and an RMS on-state current of 4 A. The device operates with a gate trigger current of 200 uA and maintains a holding current maximum of 6 mA. It utilizes a DPAK-2 (TO-252-2) package, supporting installation via SMD/SMT methods. The component functions within a temperature range from -40 C to +110 C.
Feature Summary
- Surface-mount construction in a compact DPAK-2 package
- Low gate trigger current capability for efficient control
- High surge current handling capacity
Applications
- Solid state relays
- Industrial motor control
- Power switching circuits
Procurement Notes
Verify the specific suffix against manufacturer documentation to confirm exact electrical characteristics. Confirm RoHS compliance status through official datasheets before integration. Ensure the ordering quantity aligns with reel or cut tape availability constraints specified by authorized distributors.
Selection Notes
Select this component when a 400 V blocking voltage and 4 A continuous current rating are required in a surface-mount form factor. Evaluate thermal management requirements based on the DPAK-2 package limitations. Compare gate sensitivity specifications against drive circuit capabilities to ensure reliable triggering under all operating conditions.
Part Context
This part belongs to the Sxx04xSx series of SCRs manufactured by Littelfuse. These devices are engineered for general-purpose power control applications requiring robust performance in compact electronic assemblies. The series offers standardized ratings for common industrial and consumer power electronics designs.
Replacement Considerations
Consult Littelfuse official substitution guides for verified equivalents. Cross-reference pinout compatibility and thermal resistance values when considering alternative manufacturers. Verify that any substitute meets the same 400 V and 4 A specifications.
