JSM501

JSMSEMI · Hall Sensor · SOT-23-3L

JSM501 from JSMSEMI, in a SOT-23-3L. 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 2.7 V to 30 V; absolute max 30 V continuous (34 V for t<96 h, 36 V for t<5 min); reverse voltage rated to -20 V. Typical supply current 2.5 mA (3.2 mA max).
2 GND power_in Ground reference for the device.
3 Vout output Open-drain Hall-switch output. Drives low when magnetic flux density exceeds Bop (typ. 9 Gs) and releases high (external pull-up required) when flux drops below Brp (typ. -9 Gs). VOL typ. 0.13 V @ 20 mA; sink current up to 25 mA recommended, 65 mA absolute max. Requires external pull-up resistor RL to Vcc.

CAD (KiCad official)

  • Symbol: JSM501
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3L (KiCad packages3D, STEP)
  • 3D model files: jsm501-etched.step / jsm501-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); jsm501.step / jsm501.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: JSMSEMI datasheet (9 pp, sha256 88607659b8b749c3, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
