SS19FA

onsemi · Schottky Diodes · SOD-123FL

SS19FA 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 terminal of the Schottky rectifier, marked by the band on the package; the SS19FA is rated for a repetitive peak reverse voltage (VRRM) of 90 V.
2 Anode passive Anode terminal of the Schottky rectifier, opposite the band-marked cathode; the SS19FA is rated for an average forward rectified current (IF(AV)) of 1 A.

CAD (KiCad official)

  • Symbol: SS19FA
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: ss19fa-etched.step / ss19fa-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ss19fa.step / ss19fa.glb are the bare package body.
