BMS2301

BORN · MOSFETs · SOT-323

BMS2301 from BORN, in a SOT-323. 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 P-channel MOSFET, with VGS rated ±10 V maximum and threshold VGS(th) specified at VDS = VGS, ID = -250 µA.
2 S passive Source; body-diode anode side of the P-channel MOSFET, with drain-source voltage rated -20 V and continuous drain current -1.7 A.
3 D passive Drain; the single top-side lead of the P-channel MOSFET, with BVDS of -20 V and pulsed drain current of -3.0 A (tp=10 µs).
