AH3040

Nanjing AH Elec S & T · Hall Sensor · TO-92

AH3040 from Nanjing AH Elec S & T, in a TO-92. 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 for the Hall switch; the datasheet gives an operating supply range of 4.5 V to 24 V and an absolute maximum supply voltage of 24 V.
2 GND power_in Ground pin for the Hall switch circuit.
3 Vo output Open-collector output that delivers the digital switching signal; the datasheet limits the output low-level current IOL to 25 mA maximum and the output reverse breakdown voltage Vce to 40 V.

CAD (KiCad official)

  • Symbol: AH3040
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92 (KiCad packages3D, STEP)
  • 3D model files: ah3040-etched.step / ah3040-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ah3040.step / ah3040.glb are the bare package body.
