AH49HSC

PJSEMI · Hall Sensor · SOT-23

AH49HSC from PJSEMI, 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. Recommended operating range 3 V to 8 V (absolute max 10 V DC, 50 V instantaneous). Typical supply current ~2 mA at VCC=3.3 V.
2 OUT output Analog linear Hall-effect output. Described as 'Open Drain Output' in the pin table but functions as an analog current-source-driven voltage output (internal 65 µA current source, ~50 Ω output resistance). Quiescent voltage ~1.7 V at VCC=3.3 V (B=0 Gauss); swings ~0.85 V to ~2.6 V across ±3000 Gauss with sensitivity ~0.33 mV/Gauss.
3 GND power_in Ground / device return.

Ordering variants

  • AH49HSC

CAD (KiCad official)

  • Symbol: AH49HSC
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ah49hsc-etched.step / ah49hsc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ah49hsc.step / ah49hsc.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ah49hsc.step 59 KB You want the bare part, or you mark your own boards.
ah49hsc-etched.step 1.3 MB You want the part with AH49HSC already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 320 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: PJSEMI datasheet (6 pp, sha256 982f64b0a4f5da07, 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).
