KBU806
MDD Microdiode Semiconductor · Bridge Rectifiers · KBU
KBU806 from MDD Microdiode Semiconductor, 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 | + | power_out | Positive DC output of the bridge rectifier (pin 1, marked + on the package drawing). |
| 2 | AC1 | passive | AC input terminal (marked ~ on the drawing); the bridge is rated for 600 V repetitive peak reverse voltage (VRRM) on the KBU806. |
| 3 | AC2 | passive | AC input terminal (marked ~ on the drawing); the bridge is rated for 420 V RMS (VRMS) on the KBU806. |
| 4 | - | power_in | Negative DC output of the bridge rectifier (pin 4, marked − on the package drawing), the DC return. |
