SP2101CT3

Siliup · MOSFETs · SOT-323

SP2101CT3 from Siliup, 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 of the P-channel MOSFET; gate-source voltage limited to ±12 V absolute maximum, threshold -0.5 to -1.0 V at ID=-250µA.
2 S passive Source of the P-channel MOSFET; body diode forward voltage up to -1.2 V at IS=-1A.
3 D passive Drain of the P-channel MOSFET; drain-source voltage -20 V maximum and continuous drain current -1.2 A.
