SIP32431DR3-T1GE3 from Vishay, in a SOT-363-6. 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	OUT	output	P-channel MOSFET drain connection; switched output to the load. Bypass to ground with a 0.1 µF capacitor. Supports up to 1 A continuous switch current (1.2 A max in SC70-6).
2	GND	power_in	Device ground reference. Pins 2 and 5 are both GND on the SC70-6 package and should be connected together to the ground plane.
3	ON/OFF	input	Enable input. Logic high turns the switch on, logic low turns it off. Low-voltage logic compatible: VIH ≥ 1.3 V (for VIN 1.5-2.7 V) up to 1.8 V (for VIN 4.2-5.5 V); input leakage typ. 0.014 nA at 3.3 V. Absolute max -0.3 V to +6 V.
4	IN	power_in	P-channel MOSFET source connection; supply input. Operating range 1.5 V to 5.5 V (abs max +6 V). Bypass to ground with a 1 µF capacitor.
5	GND	power_in	Device ground reference. Second GND pin on the SC70-6 package; tie together with pin 2 to the ground plane.
6	N/C	unconnected	No internal connection. Leave floating or tie to ground; do not use as a routing via.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sip32431dr3-t1ge3.step`	99 KB	You want the bare part, or you mark your own boards.
`sip32431dr3-t1ge3-etched.step`	3.2 MB	You want the part with `SIP32431DR3-T1GE3` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 784 faces against 117 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
