# MT8313ET

**Magn Tek** · Hall Switches · SOT-23

MT8313ET from Magn Tek, in a SOT-23. 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 pin; the datasheet specifies an operating supply range of 3.8 V to 60 V and a reverse battery voltage limit of -20 V (reverse-supply protection). |
| 2 | OUT | output | Open-drain output that sinks up to 40 mA continuous with a maximum output voltage of 65 V, is current-limited, and has a saturation voltage of at most 0.4 V at 15 mA. |
| 3 | GND | power_in | Ground reference pin for the device. |

## CAD (KiCad official)

- Symbol: `MT8313ET`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `mt8313et-etched.step` / `mt8313et-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mt8313et.step` / `mt8313et.glb` are the bare package body.
