MT9105ET

Magn Tek · Position Sensor · SOT-23

MT9105ET from Magn Tek, 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 Vcc power_in Supply voltage input, 3.0V to 5.5V operating range (30V absolute max). Typical supply current ~6.7 mA at Vcc=5V.
2 Out output Ratiometric rail-to-rail analog output. Idles at Vcc/2 (2.5V at Vcc=5V) with no magnetic field; swings 0.3V..Vcc-0.3V linearly with perpendicular magnetic flux density. Source/sink capability +/-1.5 mA typical.
3 GND power_in Ground reference for the device.

CAD (KiCad official)

  • Symbol: MT9105ET
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mt9105et-etched.step / mt9105et-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mt9105et.step / mt9105et.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
mt9105et.step 59 KB You want the bare part, or you mark your own boards.
mt9105et-etched.step 1.3 MB You want the part with MT9105ET already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 331 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: Magn Tek datasheet (12 pp, sha256 a002ba99c385ccb1, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
