HESDALD08BCX

Public Made by Adom

by adom

HXY MOSFET Electrostatic And Surge Protection (TVS/ESD), SOD-323. Unpolarised two-terminal part: the datasheet prints no pin numbers, so pins 1 and 2 follow the library convention, KiCad symbol/footprint/3D.

  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: hesdald08bcx-etched.step / hesdald08bcx-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hesdald08bcx.step / hesdald08bcx.glb are the bare package body.

Provenance

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

  • Datasheet: HXY MOSFET datasheet (4 pp, sha256 0d203232191d0ecd, retrieved 2026-11-05, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins, primary two-terminal convention (convention), consensus off (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
