BML6402

BORN · MOSFETs · SOT-23

BML6402 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; the datasheet shows it at the bottom-left of the SOT-23 diagram, with gate-source voltage limited to ±12 V and threshold VGS(th) of -0.4 to -1.2 V.
2 S passive Source of the P-channel MOSFET, shown at the bottom-right of the SOT-23 diagram, with continuous drain current of -3.7 A.
3 D passive Drain, the single pin on the top side of the SOT-23 diagram, with drain-source voltage of -20 V max and pulsed drain current of -15 A.
