SM353RT

Honeywell · Hall Switches · SOT-23

SM353RT 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 VCC power_in Supply voltage input, specified at 3 V to 24 V (12 V typical) referenced to ground, with absolute maximum supply voltage of -26 V to 26 V.
2 OUTPUT output Open-collector output that sinks up to 40 mA maximum, with output saturation voltage of 500 mV maximum at 20 mA load and output leakage current of 10 µA maximum when off.
3 GND power_in Ground (-) reference for the supply voltage and all electrical specifications.

CAD (KiCad official)

  • Symbol: SM353RT
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: sm353rt-etched.step / sm353rt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sm353rt.step / sm353rt.glb are the bare package body.
