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

PESD1442U005 from Leiditech, 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 connected to the protected signal line (or GND); rated voltage 14 V max, 15 kV contact / 25 kV air discharge per IEC 61000-4-2.
2 2 passive Second terminal of the bidirectional ESD diode, connected to the protected signal line or GND; the device is symmetric, with typical capacitance 0.05 pF at VR = 0 V, 1 MHz.

CAD (KiCad official)

  • Symbol: PESD1442U005
  • 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: pesd1442u005-etched.step / pesd1442u005-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pesd1442u005.step / pesd1442u005.glb are the bare package body.
