P0102DA 1AA3 ST SCRs

The P0102DA 1AA3 is a sensitive gate SCR (silicon controlled rectifier) from STMicroelectronics in TO-92 through-hole package, featuring 400V repetitive peak off-state voltage and 0.8A RMS on-state current, suitable for applications where available gate current is limited . For selection, verify gate trigger current of 0.2mA (200µA) typical, on-state current of 0.8A, maximum junction temperature of 125°C, and ECOPACK2 compliance . Features include highly sensitive triggering levels for direct drive from low-power circuits, planar technology for high reliability, and through-hole TO-92 package for easy prototyping. Ideal for ground fault circuit interrupters (GFCI), overvoltage crowbar protection in low power supplies, capacitive ignition circuits, and any application requiring 0.8A current handling with 400V voltage rating where gate current is limited.
