KBU608
Yangzhou Yangjie Elec Tech · Bridge Rectifiers · KBU
KBU608 from Yangzhou Yangjie Elec Tech, 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, marked '-' on the body at the left-most lead in the outline drawing. |
| 2 | AC1 | passive | AC input terminal, marked AC on the body; the two AC leads are interchangeable, and the rated VRRM is 800 V for KBU608. |
| 3 | AC2 | passive | Second AC input terminal, marked AC on the body; the two AC leads are interchangeable, and the rated VRRM is 800 V for KBU608. |
| 4 | + | power_out | DC positive output of the bridge, marked '+' on the body at the right-most lead; average rectified output is 6 A with heatsink (Tc=105℃) or 2.5 A without heatsink (Ta=25℃). |
