Changjing · Bridge Rectifiers · KBL
KBL401 from Changjing, 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 | + | passive | Positive DC output of the bridge (the longer lead on the drawing); the 4A average output current at Tc=40°C and VRRM up to 1000V (device-dependent) apply to the bridge. |
| 2 | 2 | passive | AC input terminal of the bridge rectifier; each diode is rated 1.1V max VFM at IFM=4.0A. |
| 3 | 3 | passive | Second AC input terminal of the bridge rectifier; the surge current rating is 125A (60Hz sine, 1 cycle, Tj=25°C). |
| 4 | - | passive | Negative DC output of the bridge rectifier, the return terminal for the rectified output. |
