KBU6B-E4 from Vishay Intertech, in a KBU. 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 | - | power_out | DC negative output of the bridge rectifier, marked '-' on the body, leftmost lead in the package drawing. |
| 2 | 2 | passive | AC input terminal of the bridge, marked '~' on the body; VRMS rating for KBU6B is 70 V. |
| 3 | 3 | passive | Second AC input terminal of the bridge, marked ' |
| 4 | + | power_out | DC positive output of the bridge rectifier, marked '+' on the body, longest lead in the drawing; average rectified current 6.0 A. |
