P0102DA 1AA3 ST Thyristors - SCRs
The P0102DA 1AA3 is a 400V, 0.8A sensitive-gate SCR in a classic TO-92 through-hole package, ideal for low-cost AC control circuits where direct logic-level triggering is essential. Select this thyristor when your design requires reliable latching with an ultra-low 200µA gate trigger current, allowing direct drive from microcontroller GPIOs without buffer transistors. Its 5mA holding current ensures stable operation in low-load conditions. Key applications include home appliance controls (lamp dimmers, fan regulators), ground fault circuit interrupters (GFCI), gas igniters, and small solid-state relays. It also suits industrial safety circuits, overvoltage crowbar protection, and low-power motor speed controllers with -40°C to +125°C operation.
