SMF48CA

Shandong Jingdao Microelectronics · TVS · SOD-123FL

SMF48CA from Shandong Jingdao Microelectronics, 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 terminal as listed in the PINNING table; the datasheet symbol shows both unipolar and bipolar forms, so this label applies to the unidirectional symbol.
2 Anode passive Anode terminal as listed in the PINNING table; the datasheet symbol shows both unipolar and bipolar forms, so this label applies to the unidirectional symbol.

CAD (KiCad official)

  • Symbol: SMF48CA
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: smf48ca-etched.step / smf48ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smf48ca.step / smf48ca.glb are the bare package body.
