S4008DS3TP

Overview

The Littelfuse S4008DS3TP is a silicon-controlled rectifier (SCR) from the Sxx08xSx series, designed for surface-mount applications in the DPAK-2 (TO-252-2) package. It features an 8 A RMS on-state current and a 400 V rated repetitive off-state voltage. The device requires a gate trigger current of 500 uA and has a holding current maximum of 8 mA. It operates within a temperature range of -40 C to +110 C, with a non-repetitive peak on-state current capability of 100 A.

Feature Summary

Surface-mount construction in a DPAK-2 package for automated PCB assembly
High sensitivity gate triggering requiring only 500 uA
Robust thermal performance supporting operation up to +110 C

Applications

AC power control circuits
Lighting dimmer applications
Motor speed control systems

Procurement Notes

Verify the specific suffix 'TP' against official Littelfuse documentation to confirm tape-and-reel packaging details. Ensure the component matches the required DPAK-2 footprint and pinout configuration for your design. Cross-reference the datasheet for any updates regarding RoHS compliance or REACH SVHC status before finalizing procurement.

Selection Notes

Select this SCR when a low gate drive current is necessary to simplify control circuitry. The 400 V rating suits general-purpose AC applications, while the 8 A RMS current handles moderate loads. Verify that the DPAK-2 package provides adequate thermal dissipation for your specific ambient conditions and heat sinking strategy.

Part Context

This component belongs to the Littelfuse Sxx08xSx family of thyristors. These devices are engineered for reliable switching in power control environments. The S4008DS3TP variant specifically integrates the 8 A current handling and 400 V blocking capabilities into a compact surface-mount form factor suitable for modern electronics manufacturing.

Replacement Considerations

Consult Littelfuse substitution guides for compatible SCRs within the same current and voltage ratings. Verify pin compatibility and thermal characteristics before replacing with alternative manufacturers' parts.
