KUU · MOSFETs · SOT-723
KM3139K from KUU, in a SOT-723. 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 limited to ±12 V, threshold VGS(th) -0.35 to -0.8 V at ID = -250 µA, and ESD protected up to 2 kV (HBM). |
| 2 | S | passive | Source of the P-channel MOSFET; continuous drain current ID is -0.66 A (pulsed -1.2 A). |
| 3 | D | passive | Drain of the P-channel MOSFET; drain-source voltage VDS is rated -20 V and the body diode is connected between drain and source. |
