Electrical characteristics

Limits as printed in the datasheet (page.json metadata.characteristics carries them as data).

Parameter Symbol Min Typ Max Unit Conditions Page
Breakdown voltage (VBR) at test current IT 6.67 7.37 V IT = 10 (test current column of the same row) 2
Reverse leakage current (ID) at working voltage VWM 400 µA VWM = 6.0 V (same row) 2
Clamping voltage (VC) at peak pulse current 10.3 V IPP = 38.8 A (same row) 2
Reverse stand-off voltage (VWM) 6 V 2

CAD (KiCad official)

  • Symbol: SMF4L6.0A
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: smf4l6-0a-etched.step / smf4l6-0a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smf4l6-0a.step / smf4l6-0a.glb are the bare package body.

Provenance

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

  • Datasheet: FUXINSEMI datasheet (6 pp, sha256 bed6daae099f2680, retrieved 2026-11-04, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins, primary cathode-band 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).
