SMBJ5346B

LGE · Zener Diodes · SMB(DO-214AA)

SMBJ5346B from LGE, 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, the end marked by the color band; the zener is reverse-biased here, with VZ of 9.1 V at 150 mA test current for the SMBJ5346B.
2 A passive Anode, the end opposite the color band; it is the lead-formed surface-mount terminal for a 5 W zener diode.

  • Symbol: SMBJ5346B
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
  • 3D model files: smbj5346b-etched.step / smbj5346b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smbj5346b.step / smbj5346b.glb are the bare package body.
