S4008VS2TP

Overview

The S4008VS2TP is a silicon-controlled rectifier (SCR) manufactured by Littelfuse, designed for through-hole mounting in the TO-251 package. It features a rated repetitive off-state voltage of 400 V and an on-state RMS current of 8 A. The device has a gate trigger current of 200 uA and a holding current maximum of 6 mA. Non-repetitive peak on-state current reaches 100 A. Operating temperature ranges from -40 C to +110 C.

Feature Summary

Sensitive gate structure enabling reliable triggering with low gate current requirements.

Applications

General purpose power control circuits
AC switching applications
Solid state relay implementations

Procurement Notes

Verify component authenticity against Littelfuse official documentation. Confirm package type matches TO-251 specifications. Ensure operating conditions remain within the specified thermal limits. Check datasheet for detailed handling precautions.

Selection Notes

Select this SCR when a 400 V rating and 8 A continuous current capacity are required. Compare gate sensitivity against alternative thyristors if drive circuit constraints exist. Verify thermal management capabilities for the intended application environment.

Part Context

This component belongs to the Sxx08xSx series of sensitive gate SCRs. It shares design characteristics with other devices in the family, offering consistent performance metrics for industrial power control solutions.

Replacement Considerations

Consult Littelfuse official substitution guides for verified equivalents. Generic replacements may differ in gate sensitivity or thermal resistance parameters.
