P0102DA 1AA3 from STMicroelectronics, in a TO-92. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode of the SCR; the on-state current (IT(RMS) 0.8 A max) leaves the device here. |
| 2 | G | input | Gate trigger input; IGT max 200 µA and VGT max 0.8 V at VD = 12 V, RL = 33 Ω, with peak gate current IGM of 1 A for tp = 20 µs. |
| 3 | A | passive | Anode of the SCR; blocks a repetitive peak off-state voltage VDRM/VRRM of 400 V. |
