# GH43F

**GoChip Elec Tech Shanghai** · Hall Switches · TO-92S

GH43F 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 | VCC | power_in | Supply voltage pin, operating range 3.8V to 30V (absolute maximum -30V to +40V), decoupled with CIN=0.1µF in the typical application. |
| 2 | GND | power_in | Ground pin, connected to circuit ground in the typical application circuit. |
| 3 | OUT | output | Open-collector digital output that needs a pull-up resistor RL of 820Ω to 100kΩ, sinks up to 50mA (VOL 150mV typ at 25mA) and withstands 30V in the off state. |

## CAD (KiCad official)

- Symbol: `GH43F`
- Footprint: `Package_TO_SOT_THT:TO-92_Inline`
- 3D model: TO-92S (KiCad packages3D, STEP)
- 3D model files: `gh43f-etched.step` / `gh43f-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `gh43f.step` / `gh43f.glb` are the bare package body.
