EC103B2

Overview

The Littelfuse EC103B2 is a sensitive silicon-controlled rectifier (SCR) designed for half-wave unidirectional gate-controlled rectification. It features a maximum on-state current of 0.8 A and a repetitive peak off-state voltage rating of 200 V. The device utilizes glass-passivated junctions to ensure parameter stability and long-term reliability. Key electrical characteristics include a DC gate trigger current of 50 µA, a peak on-state voltage of 1.7 V, and a non-repetitive surge current capability of 50 A. It operates within a junction temperature range of -65 °C to +110 °C.

Feature Summary

Glass-passivated junction construction for enhanced environmental protection
High sensitivity gate control requiring minimal trigger current
Robust thermal performance with defined derating curves

Applications

Half-wave rectification circuits
Gate control applications for power SCRs
Lighting control systems
