A1126LUA-T

Allegro MicroSystems, LLC · Magnetic Sensors · TO-92S

A1126LUA-T from Allegro MicroSystems, LLC, in a TO-92S. 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 Connects the power supply to the chip; operating supply voltage is 3 to 24 V with TJ below 165°C, and forward supply voltage is rated to 28 V.
2 GND power_in Ground connection for the device.
3 VOUT output Open-drain output that switches low when the operate point is reached, sinking up to the output current limit IOM of 30 to 60 mA, with output off voltage rated to 28 V.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts tin UA is a three-lead ultra-mini SIP for through-hole mounting. Each package is lead (Pb) free, with 100% matte-tin-plated leadframe. 2

CAD (KiCad official)

  • Symbol: A1126LUA-T
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92S (KiCad packages3D, STEP)
  • 3D model files: a1126lua-t-etched.step / a1126lua-t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); a1126lua-t.step / a1126lua-t.glb are the bare package body.
