P0102BL5AA4 from STMicroelectronics, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode terminal of the sensitive SCR; current-carrying terminal, on-state rms current up to 0.25 A in the SOT23-3L package. |
| 2 | G | input | Gate terminal used to trigger the SCR into conduction; triggering gate current (IGT) up to 200 µA max (VD = 12 V, RL = 140 Ω). |
| 3 | A | passive | Anode terminal of the sensitive SCR; blocks repetitive peak off-state voltage (VDRM/VRRM) according to the device voltage grade. |
