Z0103MA 1AA2 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 | A1 | passive | Main terminal 1 (anode 1); carries on-state rms current IT(RMS) up to 1 A at TL = 50 °C; gate trigger voltage and threshold voltage are referenced to A1; VDRM/VRRM 600 V (M-voltage variant). |
| 2 | A2 | passive | Main terminal 2 (anode 2); carries on-state rms current IT(RMS) up to 1 A at TL = 50 °C; peak on-state voltage VTM max 1.6 V at ITM = 1.4 A, tp = 380 µs, Tj = 25 °C. |
| 3 | G | input | Gate trigger input; triggers conduction in quadrants I-IV; IGT max 3 mA (Q1-Q3, VD = 12 V, RL = 30 Ω), VGT max 1.3 V, peak gate current IGM = 1 A (tp = 20 µs, Tj = 125 °C), average gate power PG(AV) max 1 W. |
