HT03AM-12 from HTCSEMI, in a TO-92-3. 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 | Cathode | passive | Cathode (K) of the thyristor; main current return terminal, with IT(AV) 0.3 A and IT(RMS) 0.47 A rated on-state current. |
| 2 | Anode | passive | Anode (A) of the thyristor; main terminal with VDRM/VRRM of 600 V repetitive peak off-state/reverse voltage. |
| 3 | Gate | input | Gate trigger input; IGT 1 to 100 µA and VGT max 0.8 V at Tj = 25°C, VD = 6 V, with RGK = 1 kΩ gate-to-cathode resistance specified for ratings. |
