# RB051L-40

**Shikues** · Schottky Barrier Diodes (SBD) · SMA

RB051L-40 from Shikues, 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 | K | passive | Cathode, marked by the color band on the DO-214AC body; the device is rated for 40 V VRRM, 2.0 A average forward current and 0.55 V forward voltage at 2.0 A. |
| 2 | A | passive | Anode terminal, the end opposite the color band; the device is rated for 40 V VRRM and 50.0 A peak forward surge current (8.3 ms half sine). |

## CAD (KiCad official)

- Symbol: `RB051L-40`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA (KiCad packages3D, STEP)
- 3D model files: `rb051l-40-etched.step` / `rb051l-40-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `rb051l-40.step` / `rb051l-40.glb` are the bare package body.
