**NH** · Bridge Rectifiers · GBU

RGBU1506 from NH, 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 | Output Cathode(-) | power_out | DC output negative terminal of the bridge rectifier, identified by the "-" polarity mark on the case. |
| 2 | Input Pin(AC1) | input | AC input terminal AC1 of the bridge rectifier, one of the two AC inputs to the internal diode bridge. |
| 3 | Input Pin(AC2) | input | AC input terminal AC2 of the bridge rectifier, the second of the two AC inputs to the internal diode bridge. |
| 4 | Output Anode(+) | power_out | DC output positive terminal of the bridge rectifier, identified by the "+" polarity mark on the case. |
