S1JFL

onsemi · Diodes - General Purpose · SOD-123FL

S1JFL from onsemi, in a SOD-123FL. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Cathode passive Cathode of the general-purpose rectifier, marked by the band on the package; S1JFL blocks up to 600 V VRRM and carries 1 A average forward current.
2 Anode passive Anode of the general-purpose rectifier; S1JFL conducts 1 A average forward current with VF max 1.1 V at IF = 1 A.

CAD (KiCad official)

  • Symbol: S1JFL
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: s1jfl-etched.step / s1jfl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); s1jfl.step / s1jfl.glb are the bare package body.
