GH1104 from GoChip Elec Tech Shanghai, in a TO-92S. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Supply voltage pin; the datasheet gives an operating range of 4.5 V to 24 V for the E grade and 3.8 V to 30 V for the L grade, with an absolute maximum supply of -30 V to +40 V. |
| 2 | GND | power_in | Ground reference pin. |
| 3 | VOUT | output | Open-collector output that requires an external pull-up resistor; the datasheet limits output low current IOL to 50 mA and output reverse breakdown voltage VCE to -40 V. |
