BTA203-800CTEP from WeEn Semiconductors, 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 | T2 | passive | Main terminal 2 of the triac; the device triggers only in the T2+ G+, T2+ G- and T2- G- quadrants, with gate trigger current limited to 30 mA maximum at Tj = 25 °C. |
| 2 | G | input | Gate, which controls triac turn-on; the datasheet specifies a peak gate current limit of 2 A and a peak gate power of 5 W, with average gate power of 0.3 W over any 20 ms period. |
| 3 | T1 | passive | Main terminal 1 of the triac, the reference terminal for the 800 V repetitive peak off-state voltage (VDRM) and the 3 A RMS on-state current rating. |
