BT169EL-B-T92-B from UTC(Unisonic Tech), in a TO-92-2.54mm. 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 main terminal of the BT169E SCR, rated for repetitive peak off-state voltages VDRM/VRRM of 500 V on the BT169E. |
| 2 | G | input | Gate terminal, with peak gate voltage VGM 5 V, peak reverse gate voltage VRGM 5 V, peak gate current IGM 1 A, peak gate power PGM 2 W and average gate power PG(AV) 0.1 W (over any 20 ms period). |
| 3 | A | passive | Anode main terminal of the BT169E SCR, which carries the on-state current (IT(AV) 0.5 A, IT(RMS) 0.8 A) and blocks up to 500 V VDRM/VRRM. |
