GP1S194HCZ0F from Sharp Microelectronics, in a DIP-4. 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	A	passive	Anode of the infrared LED emitter (GaAs, 950nm). Forward voltage VF = 1.2V typ / 1.4V max at IF=20mA; absolute maximum forward current IF = 30mA; reverse voltage VR = 6V max. Drive through a current-limiting resistor from VCC.
2	K	passive	Cathode of the infrared LED emitter. Typically tied to ground (through the LED path). Package outline notes this pad is at 'same voltage with Anode' on the substrate marking side.
3	C	passive	Collector of the NPN silicon phototransistor detector. Pull to VCC through a load resistor (test condition uses RL=1kΩ). Absolute maximum VCEO = 35V; collector current Ic max = 20mA; typical Ic = 150-600μA at IF=5mA, VCE=5V.
4	E	passive	Emitter of the NPN silicon phototransistor detector. Typically connected to ground; the collector-to-emitter output is taken across the load resistor. VCE(sat) = 0.4V max at IF=10mA, Ic=40μA.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`gp1s194hcz0f.step`	158 KB	You want the bare part, or you mark your own boards.
`gp1s194hcz0f-etched.step`	2.1 MB	You want the part with `GP1S194HCZ0F` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 514 faces against 80 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.
