# BB133

**Shikues** · Diodes - Variable Capacitance · SOD-323

BB133 from Shikues, in a SOD-323. 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 of the variable capacitance diode; continuous reverse voltage max 30 V, Cd 38 to 46 pF at VR = 0.5 V. |
| 2 | ANODE | passive | Anode of the variable capacitance diode; continuous forward current max 20 mA, Cd 2.2 to 2.6 pF at VR = 28 V. |

## CAD (KiCad official)

- Symbol: `BB133`
- Footprint: `Diode_SMD:D_SOD-323`
- 3D model: SOD-323 (KiCad packages3D, STEP)
- 3D model files: `bb133-etched.step` / `bb133-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bb133.step` / `bb133.glb` are the bare package body.
