# SS30AT

**Honeywell** · Linear Hall Sensors · SOT-23

SS30AT from Honeywell, 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 | Vs | power_in | Supply voltage input; operates from 4.5 V to 24.0 V, absolute maximum +28 V / −28 V reverse polarity. |
| 2 | GND | power_in | Ground / negative supply reference; emitter of internal NPN current-sinking output transistor returned here. |
| 3 | OUTPUT | output | Open-collector NPN current-sinking output; pulls low when applied magnetic field exceeds operate threshold (max 110 Gauss at 25 °C); maximum output current 20 mA, output leakage max 10 µA. |

## CAD (KiCad official)

- Symbol: `SS30AT`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `ss30at-etched.step` / `ss30at-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ss30at.step` / `ss30at.glb` are the bare package body.
