# OH513

**Nanjing Ouzhuo Tech** · Linear Hall Sensors · SOT-89

OH513 from Nanjing Ouzhuo Tech, in a SOT-89. 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 | Power supply input; operating supply voltage 4 to 30 V, absolute maximum 3.8 to 30 V per the ratings table. |
| 2 | GND | power_in | Ground reference for the supply and the open-collector output. |
| 3 | VOUT | output | Open-collector (OC) output that needs a pull-up resistor RL to the supply; maximum load current 50 mA, output low voltage typically 200 mV (max 400 mV). |

## CAD (KiCad official)

- Symbol: `OH513`
- Footprint: `Package_TO_SOT_SMD:SOT-89-3`
- 3D model: SOT-89 (KiCad packages3D, STEP)
- 3D model files: `oh513-etched.step` / `oh513-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `oh513.step` / `oh513.glb` are the bare package body.
