TCS40DLR from TOSHIBA LF, 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	VCC	power_in	Positive supply voltage input. Operating range 2.3 V to 5.5 V (absolute max 6.0 V). A 0.47 uF decoupling capacitor should be connected near the device.
2	VOUT	output	Open-drain digital output. Pulls low (VOL <= 0.5 V at IOL = 1.0 mA) when magnetic flux density >= BON; goes to high impedance when flux density <= BOFF. Requires external pull-up resistor. Max output voltage 5.5 V, max output current 5 mA.
3	GND	power_in	Ground reference (0 V).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tcs40dlr.step`	59 KB	You want the bare part, or you mark your own boards.
`tcs40dlr-etched.step`	1.4 MB	You want the part with `TCS40DLR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 351 faces against 69 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.
