Changjing · Bridge Rectifiers · KBL
KBL402 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 (cathodes of the diodes), the leftmost and longer lead in the KBL outline, for a 4A average rectified output (Tc=40℃). |
| 2 | 2 | passive | AC input terminal of the bridge, rated for repetitive peak reverse voltage up to 1000V depending on grade (KBL404 = 400V). |
| 3 | 3 | passive | Second AC input terminal of the bridge, rated for repetitive peak reverse voltage up to 1000V depending on grade (KBL404 = 400V). |
| 4 | - | passive | Negative DC output of the bridge (anodes of the diodes), the rightmost lead, with 125A non-repetitive surge forward current (60Hz, 1 cycle). |
