BT169-MS from MSKSEMI, in a SOT-89. 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 | G | input | Gate of the thyristor; peak gate current IGM is rated at 1.0 A and average gate power PG(AV) at 0.1 W, with gate trigger current IGT of 10 to 200 µA and gate trigger voltage VGT of 0.8 V (typ) at VD=12 V, IT=0.1 A. |
| 2 | A | passive | Anode of the thyristor; the repetitive peak off-state voltages VDRM/VRRM are rated 600 V for the BT169-MS, and the peak forward on-state voltage VTM is 1.8 V at IT=1.0 A, IG=50 mA. |
| 3 | K | passive | Cathode of the thyristor; the average on-state current IT(AV) is rated 0.5 A, RMS on-state current IT(RMS) 0.8 A, and non-repetitive peak on-state current ITSM 8 A. |
