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

PESD0402-240 from Littelfuse, 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 One terminal of the bi-directional ESD protector, rated 24 VDC continuous maximum operating voltage with 0.25 pF typical capacitance; connect to the protected signal line, with the opposite terminal to ground.
2 2 passive Second terminal of the bi-directional ESD protector, interchangeable with the other terminal because the part has no polarity mark; 10 µA maximum leakage at 24 VDC.

CAD (KiCad official)

  • Symbol: PESD0402-240
  • 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: pesd0402-240-etched.step / pesd0402-240-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pesd0402-240.step / pesd0402-240.glb are the bare package body.
