RB161M-20TR-FS

FUXINSEMI · Schottky Barrier Diodes (SBD) · SOD-123

RB161M-20TR-FS from FUXINSEMI, in a SOD-123. 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, identified by the color band on the package; the datasheet rates this Schottky rectifier for 40 V repetitive peak reverse voltage and 1.0 A average forward rectified current.
2 Anode passive Anode of the Schottky barrier rectifier; the datasheet gives 35 A peak forward surge current (8.3 ms single half sine-wave) and a maximum instantaneous forward voltage of 0.38 V at 1.0 A.

CAD (KiCad official)

  • Symbol: RB161M-20TR-FS
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: rb161m-20tr-fs-etched.step / rb161m-20tr-fs-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rb161m-20tr-fs.step / rb161m-20tr-fs.glb are the bare package body.
