KBL406 from MDD（Microdiode Electronics）, 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; rectified output rated 4.0 A average at TA=50°C. |
| 2 | AC1 | passive | AC input terminal (~); KBL406 is rated 600 V VRRM and 420 V VRMS. |
| 3 | AC2 | passive | AC input terminal (~); KBL406 is rated 600 V VRRM and 420 V VRMS. |
| 4 | - | power_out | Negative DC output of the bridge (return); peak forward surge current 200 A. |
