KBU8005

Changjing · Bridge Rectifiers · KBU

KBU8005 from Changjing, 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 - passive DC negative output of the bridge, with VRRM 50V to 1000V depending on suffix and Io 8A at Tc=100℃.
2 2 passive AC input of the bridge, with surge current IFSM 200A (60Hz sine, 1 cycle, Tj=25℃).
3 3 passive Second AC input of the bridge, with surge current IFSM 200A (60Hz sine, 1 cycle, Tj=25℃).
4 + passive DC positive output of the bridge, with Io 8A at Tc=100℃ and VFM max 1.0V per diode at IFM=4.0A.
