DF5A6.2LJE

TOSHIBA · ESD And Surge Protection (TVS/ESD) · SOT-553

DF5A6.2LJE from TOSHIBA, in a SOT-553. 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 CATHODE1 passive Cathode of ESD protection diode 1 (Zener VZ 5.9 to 6.5 V at IZ = 5 mA), connected to the line to be protected.
2 ANODE passive Common anode of all four diodes, normally connected to ground.
3 CATHODE2 passive Cathode of ESD protection diode 2 (Zener VZ 5.9 to 6.5 V at IZ = 5 mA), connected to the line to be protected.
4 CATHODE3 passive Cathode of ESD protection diode 3 (Zener VZ 5.9 to 6.5 V at IZ = 5 mA), connected to the line to be protected.
5 CATHODE4 passive Cathode of ESD protection diode 4 (Zener VZ 5.9 to 6.5 V at IZ = 5 mA), connected to the line to be protected.

CAD (KiCad official)

  • Symbol: DF5A6.2LJE
  • Footprint: Package_TO_SOT_SMD:SOT-553
  • 3D model: SOT-553 (KiCad packages3D, STEP)
  • 3D model files: df5a6-2lje-etched.step / df5a6-2lje-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); df5a6-2lje.step / df5a6-2lje.glb are the bare package body.
