KBU606 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 | - | passive | DC negative output of the bridge rectifier, marked '-' on the body outline; the part is rated 6 A average output with heatsink (Tc=105°C) and 2.5 A without (Ta=25°C). |
| 2 | AC1 | passive | First AC input of the bridge, marked 'AC' on the body outline; KBU606 is rated VRRM 600 V. |
| 3 | AC2 | passive | Second AC input of the bridge, marked 'AC' on the body outline; KBU606 is rated VRRM 600 V. |
| 4 | + | passive | DC positive output of the bridge rectifier, marked '+' on the body outline; forward voltage is 1.0 V per diode at IFM=3 A. |
