S402TSRP

Overview

The Littelfuse S402TSRP is a sensitive gate Silicon Controlled Rectifier (SCR) from the Sx02xS series, packaged in an SOT-223 surface-mount format. It features a rated repetitive off-state voltage of 400 V and an RMS on-state current of 1.5 A. The device has a maximum holding current of 5 mA, with a gate trigger voltage of 800 mV and a gate trigger current of 200 uA. Operating within a temperature range of -40 C to +125 C, it exhibits a forward voltage of 1.7 V and a maximum leakage current of 5 uA at VDRM.

Feature Summary

Sensitive gate architecture for low-power triggering applications
Surface-mount SOT-223 package design for automated assembly
High thermal stability supporting operation up to 125 C

Applications

General purpose AC power control circuits
Lighting dimmer implementations
Motor speed regulation systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm exact packaging configuration and compliance status. Ensure the component matches the required voltage and current ratings for the target circuit design before finalizing procurement orders.

Selection Notes

Select this SCR based on its 400 V blocking capability and 1.5 A continuous current rating. Consider the sensitive gate requirements which necessitate a low gate trigger current of 200 uA. Verify that the SOT-223 footprint aligns with the printed circuit board layout constraints.

Part Context

This component belongs to the Littelfuse Sx02xS series of SCRs. These devices are designed for general-purpose switching applications requiring reliable performance in compact surface-mount configurations. The series offers various voltage ratings to suit different power control needs.

Replacement Considerations

Consult official Littelfuse documentation for verified cross-reference part numbers. Do not substitute with generic equivalents without confirming matching electrical parameters and physical dimensions.
