S402ES1AP

Overview

The Littelfuse S402ES1AP is a sensitive gate Silicon Controlled Rectifier (SCR) belonging to the Sx02xS series. It features a TO-92 through-hole package and supports an RMS on-state current of 1.5 A with a rated repetitive peak off-state voltage of 400 V. Key electrical parameters include a maximum holding current of 5 mA, a gate trigger voltage of 800 mV, and a gate trigger current of 200 uA. The device operates within a temperature range of -40 C to +125 C and exhibits a forward voltage drop of 1.7 V.

Feature Summary

Sensitive gate architecture enabling reliable triggering with low gate current requirements
Robust thermal performance supporting operation in high-temperature environments up to 125 C
Compact TO-92 through-hole form factor suitable for space-constrained circuit board layouts

Applications

Lighting control circuits requiring precise phase angle regulation
Solid-state relay designs utilizing low-power gate drive signals
General-purpose AC power switching applications

Procurement Notes

Verify the specific ordering suffix against official Littelfuse documentation to ensure correct packaging configuration. Confirm that the component meets all required environmental standards for the intended deployment environment before finalizing procurement orders.

Selection Notes

Select this component when a low-cost, sensitive-gate SCR is required for moderate current switching. Ensure the gate drive circuit can supply at least 200 uA to guarantee reliable turn-on. Verify that the 400 V voltage rating exceeds the peak line voltage plus transient spikes in the target application.

Part Context

This part belongs to the Sx02xS family of sensitive gate SCRs from Littelfuse. These devices are designed as cost-effective solutions for general-purpose power control. The family shares common packaging and basic electrical characteristics while varying in voltage ratings and current capacities to suit different load requirements.
