BT151 from WEIDA, in a TO-252. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode; main current output terminal, rated IT(RMS) = 12 A, VRRM = 650 V repetitive peak reverse voltage. |
| 2 | A | passive | Anode; main current input terminal, rated IT(RMS) = 12 A, VDRM = 650 V repetitive peak off-state voltage; exposed metal tab is also connected to this pin (Rth(j-c) = 1.4 °C/W). |
| 3 | G | input | Gate; trigger input for SCR turn-on, IGT = 15 mA max, VGT = 1.5 V max at VD = 12 V, RL = 33 Ω. |
