BT151S-500R from WEIDA, in a TO-252. 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, labelled K(1) in the symbol and pin 1 on the TO-252-4R drawing; the datasheet gives no further limits for this pin. |
| 2 | A | passive | Anode, labelled A(2) in the symbol and pin 2 on the TO-252-4R drawing; the datasheet gives no further limits for this pin. |
| 3 | G | input | Gate, labelled G(3) in the symbol and pin 3 on the TO-252-4R drawing; IGT is 15 mA max at VD=12V, RL=33Ω, VGT is 1.5 V max, IGM is 2 A and PGM is 5 W. |
