SI2301

YONGYUTAI · MOSFETs · SOT-23

SI2301 from YONGYUTAI, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	G	input	Gate. Controls the channel; VGS(th) typ -0.62 V, absolute max VGS = ±10 V. Drive to a negative VGS (relative to source) to enhance the P-channel.
2	S	passive	Source. Typically tied to the higher potential (e.g. VBUS) in a high-side P-channel switch topology.
3	D	passive	Drain. Channel current path to the load; ID = -2.2 A continuous, -8 A pulsed. BVDSS = -20 V. Body diode (drain-to-source) VSD max -1.5 V at IS = -0.75 A.
