SMBJ5355B

Slkor(SLKORMICRO Elec.) · Zener Diodes · SMB(DO-214AA)

SMBJ5355B from Slkor(SLKORMICRO Elec.), in a SMB(DO-214AA). 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, marked by the color band on the body; the 5 W zener (SMBJ5355B, 5% tolerance) regulates with this terminal positive relative to the anode.
2 A passive Anode, the terminal opposite the color band; forward voltage is max 1.2 V at IF=1.0A.

CAD (KiCad official)

  • Symbol: SMBJ5355B
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
  • 3D model files: smbj5355b-etched.step / smbj5355b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smbj5355b.step / smbj5355b.glb are the bare package body.
