ESD7C5.0DT5G

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

ESD7C5.0DT5G from onsemi, 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 CATHODE passive Diode cathode terminal of the unidirectional ESD protection diode, rated for a 5.0 V stand-off voltage and an IEC 61000-4-2 contact ESD rating of ±8.0 kV.
2 CATHODE passive Second cathode terminal, designated CATHODE alongside pin 1 in the pin assignment; the datasheet does not describe any internal connection between pins 1 and 2.
3 ANODE passive Diode anode terminal of the ESD protection diode, connected to the signal or line to be protected against ESD transients.

CAD (KiCad official)

  • Symbol: ESD7C5.0DT5G
  • 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: esd7c5-0dt5g-etched.step / esd7c5-0dt5g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd7c5-0dt5g.step / esd7c5-0dt5g.glb are the bare package body.
