EC103D2

Overview

The Littelfuse EC103D2 is a silicon controlled rectifier (SCR) from the EC103xx series, designed for phase control applications. It features a sensitive gate requiring only 12 uA of trigger current. The device supports a rated repetitive off-state voltage (VDRM) of 400 V and an RMS on-state current (ITRMS) of 800 mA. Key electrical parameters include a maximum holding current of 5 mA, a forward voltage of 1.7 V, and a non-repetitive peak on-state current of 20 A. It operates within a temperature range of -40 C to +110 C and is housed in a TO-92 through-hole package.

Feature Summary

Sensitive gate architecture enables triggering with microampere currents from sense coils or microprocessors
Robust unidirectional switching capability suitable for heating and motor speed control circuits

Applications

Phase control systems for electric heating elements
Motor speed control circuits
Lighting dimmer applications

Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact voltage ratings and pinout configurations. Ensure compatibility with existing PCB footprints and thermal management requirements before integration into production designs.

Selection Notes

Select this component when low gate drive current is required for sensitive control interfaces. Confirm that the 400 V blocking voltage meets circuit demands and that the TO-92 package accommodates available board space and thermal dissipation needs.

Part Context

This part belongs to the EC103xx series of sensitive gate SCRs manufactured by Littelfuse. The series provides reliable switching solutions for AC power control applications where minimal gate drive power is necessary for efficient operation.

Replacement Considerations

Consult Littelfuse datasheets for direct equivalents within the EC103xx family or cross-reference with other manufacturers offering 400V 0.8A sensitive gate SCRs in TO-92 packages.
