FFM101-M

Changjing · Fast Recovery / High Efficiency Diodes · SOD-123FL

FFM101-M from Changjing, 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 K passive Cathode, identified by the color band on the package; the cathode side of the rectifier diode (VRRM 50V for FFM101-M, IF(AV) 1A).
2 A passive Anode of the rectifier diode, the end opposite the cathode band (IF(AV) 1A, peak forward voltage 1.3V at IF=1.0A).

CAD (KiCad official)

  • Symbol: FFM101-M
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: ffm101-m-etched.step / ffm101-m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ffm101-m.step / ffm101-m.glb are the bare package body.
