JY809ES3-SX

Shenzhen JingYang · Supervisor and Reset ICs · SOT-23

JY809ES3-SX from Shenzhen JingYang, 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 GND power_in Ground reference for the supervisor.
2 RESET output Active-low reset output (open with internal drive). Remains low while VCC is below the factory reset threshold and for 250ms (typ., 140ms min.) after VCC rises above the threshold. Guaranteed valid for VCC >= 1.1V; a 100kΩ pull-down is recommended if logic must be defined below 1.1V. VOL <= 0.1V (R/S/T, ISINK=1.2mA) / 0.2V (L/M/J, ISINK=3.2mA); VOH >= 0.9*VCC (R/S/T) / VCC-1.5 (L/M/J).
3 VCC power_in Supply voltage. Operating range 1.1V (TA=0..70°C) or 1.2V (TA=-40..105°C) up to 5.5V. Absolute max -0.3V to 6.0V.

CAD (KiCad official)

  • Symbol: JY809ES3-SX
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: jy809es3-sx-etched.step / jy809es3-sx-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); jy809es3-sx.step / jy809es3-sx.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
jy809es3-sx.step 59 KB You want the bare part, or you mark your own boards.
jy809es3-sx-etched.step 2.2 MB You want the part with JY809ES3-SX already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 525 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: Shenzhen JingYang datasheet (5 pp, sha256 1826e8500c36d006, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
