# VBUS05B1-SD0-G4-08

**Vishay Intertech** · ESD And Surge Protection (TVS/ESD) · 0201

VBUS05B1-SD0-G4-08 from Vishay Intertech, in a 0201. 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 | 1 | passive | One terminal of the bidirectional symmetrical ESD diode (pin 1 is marked by the open circle), connected to the protected signal/data line or to ground, clamping transients up to ±16 kV contact/air with a working range of ±5.5 V. |
| 2 | 2 | passive | Second terminal of the bidirectional symmetrical ESD diode, connected to ground or to the protected signal/data line; pin 1 to pin 2 peak pulse power is 45 W (8/20 µs) and peak pulse current is 2.5 A. |

## CAD (KiCad official)

- Symbol: `VBUS05B1-SD0-G4-08`
- Footprint: `Diode_SMD:D_0201_0603Metric`
- 3D model: 0201, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.3 mm nominal _01005_ height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `vbus05b1-sd0-g4-08-etched.step` / `vbus05b1-sd0-g4-08-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `vbus05b1-sd0-g4-08.step` / `vbus05b1-sd0-g4-08.glb` are the bare package body.
