Product data sheet
1. General description
Planar passivated SCR with sensitive gate in a SOT223 surface mountable plastic package. This
SCR is designed to be interfaced directly to microcontrollers, logic integrated circuits and other low
power gate trigger circuits.
2. Features and benefits
Sensitive gate
High surge current capability
High voltage capability
Planar passivated for voltage ruggedness and reliability
Direct triggering from low power drivers and logic ICs
Surface mountable package
3. Applications
Ground Fault Circuit Interrupter (GFCI)
GFCI Socket
Residual Current Circuit Breaker with Overcurrent Protection (RCBO)
Arc Fault Circuit Interrupter (AFCI)
