BORN · MOSFETs · SOT-323
BMSN3139 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; gate-source voltage limited to ±12 V, with threshold VGS(th) between -0.4 V and -1.1 V at ID=-250 µA. |
| 2 | S | passive | Source of the P-channel MOSFET; drain-source voltage rated -20 V and body diode forward voltage max -1.2 V at ISD=-0.7 A. |
| 3 | D | passive | Drain; continuous drain current -2.0 A, pulsed -10 A, with RDS(ON) max 135 mΩ at VGS=-4.5 V. |
