# GBU108SF

**YFW** · Bridge Rectifiers · GBU

GBU108SF from YFW, in a GBU. 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 | + | passive | Output Anode (+), the positive DC output of the bridge rectifier; the part is rated for 10.0 A average forward current at TC=100°C. |
| 2 | 2 | passive | Input pin (~), AC input of the bridge; GBU108SF is rated for 600 V VRRM and 420 V VRMS. |
| 3 | 3 | passive | Input pin (~), second AC input of the bridge; GBU108SF is rated for 600 V VRRM and 420 V VRMS. |
| 4 | - | passive | Output Cathode (-), the negative DC output of the bridge rectifier. |

## CAD (KiCad official)

- Symbol: `GBU108SF`
- Footprint: `Diode_THT:Diode_Bridge_Vishay_GBU`
- 3D model: GBU (KiCad packages3D, STEP)
- 3D model files: `gbu108sf-etched.step` / `gbu108sf-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `gbu108sf.step` / `gbu108sf.glb` are the bare package body.
