BL3402 from GME(银河微电), in a SOT-23. 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; controls the channel, with VGS rated ±12 V maximum and a threshold of 0.6 V min to 1.4 V max at ID = 250 µA. |
| 2 | D | passive | Drain; rated 30 V VDSS, 4 A continuous drain current at TA = 25°C and 15 A pulsed. |
| 3 | S | passive | Source; the source terminal of the N-channel MOSFET, with the body diode forward voltage at 1.0 V max at IS = 2 A. |
