S4004DS2TP

Overview

The Littelfuse S4004DS2TP is a silicon-controlled rectifier (SCR) from the Sxx04xSx series, designed for surface-mount applications in the DPAK-2 (TO-252-2) package. It features a rated repetitive off-state voltage of 400 V and an RMS on-state current of 4 A. The device has a maximum gate trigger current of 200 uA and a forward voltage of 1.6 V. Operating temperatures range from -40 C to +110 C, with a non-repetitive peak on-state current of 30 A.

Feature Summary

Surface-mount construction in a compact DPAK-2 package for automated PCB assembly
Low gate sensitivity requiring minimal trigger current for reliable activation
High thermal stability supporting operation up to 110 C

Applications

General purpose power control circuits
Lighting dimmer applications
Solid-state relay inputs

Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm package type and tape/reel specifications. Ensure the ordering part number matches the required mounting style and packaging format for your production line. Cross-reference the datasheet revision date to confirm parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when a 4 A RMS SCR is required in a surface-mount form factor. Compare the 400 V blocking capability and low gate trigger requirements against circuit demands. Verify that the DPAK-2 thermal dissipation characteristics meet the system's junction temperature limits under expected load conditions.

Part Context

This SCR belongs to the Sxx04xSx family of high-sensitivity devices. The series offers various voltage ratings while maintaining consistent current handling and package options. This specific model provides a balance of moderate current capacity and standard voltage blocking suitable for general industrial and consumer electronics power control tasks.

Replacement Considerations

Direct replacements within the same series include S4004DS2RP. Verify pinout compatibility and thermal resistance differences between tube and reel packaging variants before substituting.
