UESD3.3DT5G

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

UESD3.3DT5G 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 Cathode terminal of the ESD protection diode; the datasheet gives no separate electrical limit for this pin beyond the device maximum ratings (ESD ±30 kV IEC 61000-4-2 contact/air, 16 kV HBM, 400 V MM, 40 A IEC 61000-4-4).
2 CATHODE passive Second cathode terminal of the ESD protection diode, connected internally with pin 1 as stated in the pin assignment; no separate limit is given for this pin.
3 ANODE passive Anode terminal of the ESD protection diode, which clamps ESD transients to the cathode pins; the datasheet gives no separate electrical limit for this pin.

CAD (KiCad official)

  • Symbol: UESD3.3DT5G
  • 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: uesd3-3dt5g-etched.step / uesd3-3dt5g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); uesd3-3dt5g.step / uesd3-3dt5g.glb are the bare package body.
