SS495A1 from Honeywell, in a TO-92S. 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	Vs	power_in	Positive supply voltage (Vs+). Operating range 4.5 to 10.5 VDC; absolute maximum -0.5 to +11 VDC. Typical supply current 7 mA at 5 VDC, 25 C (max 8.7 mA).
2	V-	power_in	Ground / negative supply return (V-). Common reference for supply and ratiometric analog output.
3	OUTPUT	output	Ratiometric analog Hall output. Null 2.50 V ±0.075 at 0 gauss (Vs=5 V), sensitivity 3.125 mV/G ±0.094, span 0.2 V to (Vs-0.2 V) typical. Sink or source 1.5 mA typical, 10 mA absolute maximum. Responds to both positive and negative gauss over ±670 G typical.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ss495a1.step`	27 KB	You want the bare part, or you mark your own boards.
`ss495a1-etched.step`	1.3 MB	You want the part with `SS495A1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 321 faces against 19 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.
