SS54A

Public Made by Adom

by adom

Guangdong Hottech Schottky Barrier Diodes (SBD), SMA(DO-214AC). Unpolarised two-terminal part: the datasheet prints no pin numbers, so pins 1 and 2 follow the library convention, KiCad symbol/footprint/3D.

CAD (KiCad official)

  • Symbol: SS54A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: ss54a-etched.step / ss54a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ss54a.step / ss54a.glb are the bare package body.

Provenance

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