NP2305MR

NATLINEAR · MOSFETs · SOT-23-3L

NP2305MR from NATLINEAR, in a SOT-23-3L. 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 of the P-channel MOSFET, with gate-source voltage limited to ±12 V and operation stated down to 1.8 V gate drive.
2 S passive Source of the P-channel MOSFET; the source diode forward current Is is rated at -1.25 A.
3 D passive Drain of the P-channel MOSFET, with drain-source voltage limited to -20 V and continuous drain current rated at -4 A.
