For overvoltage crowbar protection (triggers SCR to blow fuse on OVP), alarm bell driving, small solenoid control, and low-power lamp dimming.","working_principle":"PNPN four-layer structure latches on when gate current exceeds 200uA. The ultra-sensitive gate allows direct connection to CMOS microcontroller outputs (4mA sink\/source >> 200uA gate trigger). Once latched, the SCR conducts until anode current drops below 5mA holding current. In AC circuits, self-commutation occurs at zero crossing. The crowbar application connects the SCR across the supply; on overvoltage, the gate is triggered, the SCR shorts the supply rail, and the fuse blows, protecting the load.","pin_description":"
