S1DFL

onsemi · Diodes - General Purpose · SOD-123F

S1DFL from onsemi, in a SOD-123F. 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 terminal, identified by the band on the package; for the S1DFL the VRRM is 200 V and the average forward current IF(AV) is 1 A.
2 Anode passive Anode terminal of the rectifier, opposite the banded cathode; the datasheet gives no separate pin limit for this terminal beyond the device ratings.

CAD (KiCad official)

  • Symbol: S1DFL
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123F (KiCad packages3D, STEP)
  • 3D model files: s1dfl-etched.step / s1dfl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); s1dfl.step / s1dfl.glb are the bare package body.
