KBL406

MDD（Microdiode Electronics） · Bridge Rectifiers · KBL

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.
