MBR20100DY

Shandong Jingdao Microelectronics · Schottky Diodes · TO-252

MBR20100DY from Shandong Jingdao Microelectronics, in a TO-252. 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 A1 passive Anode input of the Schottky rectifier, shown tied with PIN3 to the diode anode in the page 1 symbol; part rated 100 V VRRM and 20 A average forward current.
2 K passive Cathode of the Schottky rectifier, also the exposed tab (PIN2 is labelled on both the tab and the centre lead); 100 V maximum DC blocking voltage.
3 A2 passive Anode input of the Schottky rectifier, shown tied with PIN1 to the diode anode in the page 1 symbol; part rated 100 V VRRM and 20 A average forward current.

CAD (KiCad official)

  • Symbol: MBR20100DY
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: mbr20100dy-etched.step / mbr20100dy-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mbr20100dy.step / mbr20100dy.glb are the bare package body.
