GP1S094HCZ0F 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	Anode	passive	Anode of the infrared emitting diode (IRED) on the emitter side. Drive with forward current IF up to 50mA max (VF typ 1.2V, max 1.4V at IF=20mA). Use a series current-limit resistor to set IF (typical operating IF=5mA at VCE=5V).
2	Collector	passive	Collector of the NPN phototransistor on the detector side. VCEO max 35V, IC max 20mA. Typical output collector current IC = 40-400uA at VCE=5V, IF=5mA. Connect through a load resistor RL to VCC to develop the output voltage.
3	Emitter	passive	Emitter of the NPN phototransistor on the detector side. Typically tied to GND. VECO max 6V. Collector-emitter saturation voltage VCE(sat) max 0.4V at IF=10mA, IC=40uA.
4	Cathode	passive	Cathode of the infrared emitting diode (IRED) on the emitter side. Typically tied to GND (or the low side of the current-limit resistor). Peak emission wavelength 950nm (GaAs, non-coherent).

3D model: DIP-4 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`gp1s094hcz0f.step`	158 KB	You want the bare part, or you mark your own boards.
`gp1s094hcz0f-etched.step`	2.3 MB	You want the part with `GP1S094HCZ0F` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 544 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.
