P0102AL 5AA4 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 | A | passive | Anode terminal of the SCR; forms the main current path with the cathode, rated IT(RMS) 0.25 A and VDRM/VRRM 100 V. |
| 2 | G | input | Gate trigger input; typical/max trigger current IGT 200 µA, max VGT 0.8 V, peak gate current IGM 0.5 A, average gate power dissipation PG(AV) 0.02 W. |
| 3 | K | passive | Cathode terminal, the reference/return terminal for anode and gate currents; holding current IH max 6 mA at IT = 50 mA. |
