S4008DS2TP

Overview

The S4008DS2TP is a silicon-controlled rectifier (SCR) manufactured by Littelfuse Inc. It belongs to the Sxx10xSx series and features a DPAK-2 (TO-252-2) surface-mount package. The device has a rated repetitive off-state voltage of 400 V and an on-state RMS current of 8 A. Key electrical parameters include a maximum gate trigger voltage of 800 mV, a gate trigger current of 200 uA, and a forward voltage of 1.6 V. It operates within a temperature range of -40 C to +110 C.

Feature Summary

Sensitive gate triggering for low-power control applications
Surface-mount construction for automated PCB assembly
High thermal stability for demanding environments

Applications

AC power control circuits
Lighting dimmer systems
Motor speed control

Procurement Notes

Verify the specific suffix 'TP' against the manufacturer's official datasheet to confirm packaging details and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the Littelfuse part number with authorized distributor catalogs to confirm availability and authenticity before procurement.

Selection Notes

Select this SCR based on its 400 V blocking capability and 8 A RMS current rating. Verify that the gate trigger characteristics align with the driving circuit's output capabilities. Consider the DPAK-2 package size for space-constrained designs requiring surface-mount technology.

Part Context

This component is part of Littelfuse's Sxx10xSx series of sensitive gate SCRs. These devices are designed for general-purpose AC switching applications where low gate drive power is required. The series offers various voltage and current ratings in standardized packages.

Replacement Considerations

Consult Littelfuse documentation for direct replacements or pin-compatible alternatives within the same series. Verify electrical parameters such as holding current and surge current when substituting with components from other manufacturers.
