GBU4005G 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 | DC negative output of the bridge rectifier (leftmost lead in the schematic, marked "-"). |
| 2 | 2 | passive | AC input terminal of the bridge; rated for 35 V RMS maximum on GBU4005G (VRMS), with 4.0 A average forward current with heatsink. |
| 3 | 3 | passive | Second AC input terminal of the bridge; rated for 35 V RMS maximum on GBU4005G (VRMS). |
| 4 | + | passive | DC positive output of the bridge rectifier (rightmost lead in the schematic, marked "+"); GBU4005G is rated for 50 V VRRM and 4.0 A average forward current with heatsink. |
