EC103DAP

Overview

The Littelfuse EC103DAP is a sensitive gate silicon-controlled rectifier (SCR) rated for 400V repetitive off-state voltage and 800mA RMS on-state current. It features a maximum gate trigger current of 500µA and a gate trigger voltage of 800mV. The device operates within a temperature range of -40°C to 110°C, with a maximum junction temperature of 150°C. It utilizes a TO-92-3 package with formed leads.

Feature Summary

Sensitive gate design enabling easy triggering with low gate current
Unidirectional switching capability for phase control applications
Robust thermal performance suitable for industrial environments

Applications

Heating control systems
Motor speed controls
Phase control circuits

Procurement Notes

Verify the specific suffix 'DAP' against the manufacturer's official datasheet to confirm pinout configuration and lead form. Ensure the selected component matches the required 400V blocking voltage and 800mA current rating for the target application circuit.

Selection Notes

Select this component for low-power phase control applications requiring sensitive gate triggering. Confirm that the TO-92 package fits the PCB layout constraints. Verify that the 500µA gate trigger current aligns with the driving circuit capabilities.

Part Context

This part belongs to the EC103xx series of low-power SCRs from Littelfuse. The series offers various voltage ratings up to 1200V and is designed for unidirectional switching in consumer and industrial electronics.

Replacement Considerations

Consult the Littelfuse official cross-reference guide for verified substitutes. Generic replacements must match the 400V VDRM, 800mA IT(RMS), and TO-92 package specifications.
