SM2301SRL

SPS · MOSFETs · SOT-23

SM2301SRL from SPS, 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 terminal of the P-channel enhancement-mode MOSFET, with gate-source voltage rated at ±12 V (VGS).
2 S passive Source terminal of the P-channel MOSFET, serving as the reference for VGS; the device is rated for a drain-source voltage of -20 V (VDSS).
3 D passive Drain terminal of the P-channel MOSFET, rated for -20 V VDS and -2.8 A continuous drain current (ID) at TA=25°C.
