# 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.
