BM3402 from BORN, 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; 3.3V logic-level drive with VGS(TH) 0.5 to 1.2 V and absolute maximum VGS of ±16 V. |
| 2 | S | passive | Source of the N-channel MOSFET; body diode continuous source current is 1.8 A max. |
| 3 | D | passive | Drain; V(BR)DSS is 30 V minimum and continuous drain current is 5.1 A at TA=25°C. |
