GBU406

MDD Microdiode Semiconductor · Bridge Rectifiers · GBU

GBU406 from MDD Microdiode Semiconductor, in a GBU. 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; GBU406 is rated 600 V VRRM and 4.0 A average rectified current.
2 2 passive AC input terminal; GBU406 is rated 420 V RMS maximum.
3 3 passive AC input terminal; GBU406 is rated 420 V RMS maximum.
4 - passive Negative DC output of the bridge; GBU406 is rated 600 V DC blocking voltage.

  • Symbol: GBU406
  • Footprint: Diode_THT:Diode_Bridge_Vishay_GBU
  • 3D model: GBU (KiCad packages3D, STEP)
  • 3D model files: gbu406-etched.step / gbu406-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gbu406.step / gbu406.glb are the bare package body.
