KBU1510

MDD Microdiode Semiconductor · Bridge Rectifiers · KBU

KBU1510 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 + passive Positive DC output of the bridge, marked + in the pin-numbering symbol; the bridge is rated 15 A average output at TC=50°C.
2 AC1 passive AC input terminal (~) of the bridge; VRMS is 700 V maximum for KBU1510.
3 AC2 passive AC input terminal (~) of the bridge; VRMS is 700 V maximum for KBU1510.
4 - passive Negative DC output of the bridge, marked − in the pin-numbering symbol; VRRM is 1000 V for KBU1510.

CAD (KiCad official)

  • Symbol: KBU1510
  • Footprint: Diode_THT:Diode_Bridge_Vishay_KBU
  • 3D model: KBU (KiCad packages3D, STEP)
  • 3D model files: kbu1510-etched.step / kbu1510-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); kbu1510.step / kbu1510.glb are the bare package body.
