# GBU802

**Shandong Jingdao Microelectronics** · Bridge Rectifiers · GBU

GBU802 from Shandong Jingdao Microelectronics, 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 | Negative DC output of the bridge (leftmost lead in the datasheet symbol); the datasheet rates the GBU802 at 200 V VRRM and 8.0 A average forward current with heatsink. |
| 2 | 2 | passive | AC input of the bridge (second lead in the datasheet symbol); the GBU802 is rated 140 V RMS. |
| 3 | 3 | passive | AC input of the bridge (third lead in the datasheet symbol); the GBU802 is rated 140 V RMS. |
| 4 | + | passive | Positive DC output of the bridge (rightmost lead in the datasheet symbol); the datasheet rates peak forward surge current at 200 A. |

## CAD (KiCad official)

- Symbol: `GBU802`
- Footprint: `Diode_THT:Diode_Bridge_Vishay_GBU`
- 3D model: GBU (KiCad packages3D, STEP)
- 3D model files: `gbu802-etched.step` / `gbu802-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `gbu802.step` / `gbu802.glb` are the bare package body.
