KBL408
Yangzhou Yangjie Elec Tech · Bridge Rectifiers · KBL
KBL408 from Yangzhou Yangjie Elec Tech, in a KBL. 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 | Positive DC output of the bridge rectifier, shown as the first lead (+) in the schematic and marked on the body; average rectified output current is 4 A at Ta=40°C. |
| 2 | 2 | passive | AC input terminal; VRRM is 800 V for KBL408 and forward voltage is 1.05 V per diode at IFM=2A. |
| 3 | 3 | passive | Second AC input terminal; peak non-repetitive surge forward current is 120 A (60 Hz half-sine, 1 cycle, Ta=25°C). |
| 4 | - | power_in | Negative DC output (return) of the bridge rectifier, shown as the last lead (-) in the schematic and marked on the body. |
