KESD5311X

KUU · ESD And Surge Protection (TVS/ESD) · 0402

KESD5311X from KUU, in a 0402. 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 1 passive Bidirectional ESD protection terminal 1 of the single-line suppressor, rated for 5.0 V max continuous operating voltage and IEC 61000-4-2 8 kV contact / 15 kV air discharge.
2 2 passive Bidirectional ESD protection terminal 2 of the single-line suppressor, interchangeable with pin 1, with 0.05 pF typical capacitance and 100 nA max leakage at 5 V.

CAD (KiCad official)

  • Symbol: KESD5311X
  • Footprint: Diode_SMD:D_0402_1005Metric
  • 3D model: 0402, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.4 mm nominal 0402 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: kesd5311x-etched.step / kesd5311x-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); kesd5311x.step / kesd5311x.glb are the bare package body.
