# R5000

**YFW** · Diodes - General Purpose · SMA

R5000 from YFW, in a SMA. 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 rectifier diode; the datasheet gives no pin-specific limits, only device ratings of 1200 to 5000 V reverse voltage and 0.5/0.2 A average forward current. |
| 2 | Anode | passive | Anode terminal of the rectifier diode; the datasheet gives no pin-specific limits, only device ratings of 1200 to 5000 V reverse voltage and 0.5/0.2 A average forward current. |

## CAD (KiCad official)

- Symbol: `R5000`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA (KiCad packages3D, STEP)
- 3D model files: `r5000-etched.step` / `r5000-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `r5000.step` / `r5000.glb` are the bare package body.
