# OH413

**Nanjing Ouzhuo Tech** · Linear Hall Sensors · TO-92S

OH413 from Nanjing Ouzhuo Tech, 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 4 to 30 V (absolute rating 3.8-30 V). |
| 2 | GND | power_in | Ground pin. |
| 3 | VOUT | output | Open-collector output that needs a pull-up resistor RL to VCC (1 kΩ in the test circuit); max output low current 50 mA. |

## CAD (KiCad official)

- Symbol: `OH413`
- Footprint: `Package_TO_SOT_THT:TO-92_Inline`
- 3D model: TO-92S (KiCad packages3D, STEP)
- 3D model files: `oh413-etched.step` / `oh413-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `oh413.step` / `oh413.glb` are the bare package body.
