Overview
The Littelfuse S4004DS1TP is a silicon-controlled rectifier (SCR) designed for surface-mount applications in the TO-252AA (DPAK) package. It features a rated repetitive peak off-state voltage of 400 V and an RMS on-state current of 4 A. The device supports a non-repetitive surge current of 30 A and operates within a junction temperature range of -40°C to +110°C. Key electrical characteristics include a gate trigger voltage of 800 mV, a gate trigger current of 200 µA, and a holding current maximum of 6 mA. The component exhibits a forward voltage drop of 1.6 V at rated current and maintains a low off-state leakage current of 2 µA under blocking conditions.
Feature Summary
- Logic-level gate sensitivity enabling direct drive from microcontrollers or logic circuits without additional amplification stages.
- Surface-mount DPAK packaging optimized for automated PCB assembly and compact power control designs.
- High thermal stability supporting reliable operation across extended industrial temperature ranges.
Applications
- Solid-state relays requiring compact switching elements
- General-purpose AC power control circuits
- Lighting dimmer modules
Procurement Notes
Verify the specific suffix against manufacturer documentation to confirm exact pinout and electrical tolerances. Ensure the procurement channel provides original manufacturer traceability. Confirm RoHS compliance status through official datasheets prior to integration into regulated assemblies.
Selection Notes
Select this component when a surface-mount SCR with 4 A continuous current capability is required. The 400 V rating suits low-voltage AC systems. Verify that the 200 µA gate trigger current aligns with the driving circuit's output capabilities to ensure reliable turn-on.
Part Context
This part belongs to Littelfuse’s Sxx04xSx series of surface-mount SCRs. The series provides standardized performance for general-purpose power switching. The TO-252AA form factor allows for efficient heat dissipation relative to its small footprint compared to through-hole alternatives.
Replacement Considerations
Direct replacements must match the 400 V / 4 A rating and DPAK package. Verify gate trigger parameters closely, as logic-level variants differ significantly from standard SCRs. Consult Littelfuse cross-reference guides for verified equivalents.
