| Package | TO-92 | Model Number | WCR03-12MEP |
The WCR03 Series SCR is a planar passivated SCR with a sensitive gate, available in both surface mountable (SOT223) and through-hole (TO92) plastic packages. Designed for direct interfacing with microcontrollers, logic integrated circuits, and other low-power gate trigger circuits, this SCR offers high surge current capability and voltage ruggedness. It is ideal for applications such as Ground Fault Circuit Interrupters (GFCI), Arc Fault Circuit Interrupters (AFCI), Residual Current Devices (RCD), and Residual Current Circuit Breakers with Overload Protection (RCBO).
