ESD9R3.3ST5G

onsemi · TVS · SOD-923

ESD9R3.3ST5G from onsemi, in a SOD-923. 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 of the ESD protection diode, identified by the polarity band on the package (Style 1), and the diode clamps ESD events to a safe level for the IC.
2 ANODE passive Anode of the ESD protection diode (Style 1), which connects to the signal or ground side of the line being protected.

CAD (KiCad official)

  • Symbol: ESD9R3.3ST5G
  • Footprint: Diode_SMD:D_SOD-923
  • 3D model: SOD-923 (KiCad packages3D, STEP)
  • 3D model files: esd9r3-3st5g-etched.step / esd9r3-3st5g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd9r3-3st5g.step / esd9r3-3st5g.glb are the bare package body.
