DF3A6.2LFV

TOSHIBA · ESD And Surge Protection (TVS/ESD) · SOT-723

DF3A6.2LFV from TOSHIBA, in a SOT-723. 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 the first ESD protection Zener diode, with VZ = 5.9 to 6.5 V at IZ = 5 mA and CT = 6.5 pF (typ.) to the anode.
2 CATHODE2 passive Cathode of the second ESD protection Zener diode, with VZ = 5.9 to 6.5 V at IZ = 5 mA and CT = 6.5 pF (typ.) to the anode.
3 ANODE passive Common anode of both ESD protection diodes, which handles IEC61000-4-2 contact discharge of ±8 kV.

CAD (KiCad official)

  • Symbol: DF3A6.2LFV
  • Footprint: Package_TO_SOT_SMD:SOT-723
  • 3D model: SOT-723, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal SOT-723 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: df3a6-2lfv-etched.step / df3a6-2lfv-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); df3a6-2lfv.step / df3a6-2lfv.glb are the bare package body.
