SK1816G-AE3-R

UTC Unisonic Tech · Hall Sensor · SOT-23

SK1816G-AE3-R from UTC Unisonic Tech, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT output Open-collector Hall latch output. Sinks up to ~20 mA (VOL <= 0.7 V at 12 mA); latches LOW when magnetic flux exceeds BOP (5 mT) and latches HIGH when flux drops below BRP (-5 mT). Requires an external pull-up resistor (e.g. 10 kOhm) to VCC.
2 VCC power_in Supply voltage input, 2.5 V to 20 V. Typical supply current ~6 mA at 16 V, ~5.5 mA at 3.6 V; absolute max ICC 10 mA. Built-in protection diode is present on this pin.
3 GND power_in Ground reference for the device.

CAD (KiCad official)

  • Symbol: SK1816G-AE3-R
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: sk1816g-ae3-r-etched.step / sk1816g-ae3-r-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sk1816g-ae3-r.step / sk1816g-ae3-r.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
sk1816g-ae3-r.step 59 KB You want the bare part, or you mark your own boards.
sk1816g-ae3-r-etched.step 2.1 MB You want the part with SK1816G-AE3-R already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 521 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: UTC Unisonic Tech datasheet (8 pp, sha256 45430608d678b140, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
