KB340B-13-F

KUU · Schottky Barrier Diodes (SBD) · SMB

KB340B-13-F from KUU, in a SMB. 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 K passive Cathode, the end marked by the color band on the JEDEC SMB body; device blocks up to 40 V DC and passes 3.0 A average forward current.
2 A passive Anode, the end opposite the color band; forward voltage is 0.55 V maximum at 3.0 A.

CAD (KiCad official)

  • Symbol: KB340B-13-F
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: kb340b-13-f-etched.step / kb340b-13-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); kb340b-13-f.step / kb340b-13-f.glb are the bare package body.
