P0111MA 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 first lead labelled K on the TO-92 (P011xxA) drawing; IT(RMS) up to 0.8 A. |
| 2 | G | input | Gate trigger input, the middle lead of the TO-92; IGT is 4 µA min to 25 µA max at VD = 12 V, RL = 140 Ω, and VGT is 0.8 V max. |
| 3 | A | passive | Anode of the SCR, the third lead labelled A on the TO-92 drawing; VDRM/VRRM is 600 V for the P0111M. |
