ESD9C3.3ST5G

onsemi · ESD Protection Devices · SOD-923

ESD9C3.3ST5G 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, marked by the polarity band on the SOD-923 package; the datasheet specifies this device for a 3.3 V working peak reverse voltage (VRWM) with ESD protection rated at ±8.0 kV contact and ±15 kV air per IEC 61000-4-2.
2 ANODE passive Anode of the ESD protection diode; the datasheet gives no pin-specific limit, and the device ratings (±8.0 kV contact, ±15 kV air per IEC 61000-4-2, total power dissipation 150 mW at TA = 25°C, junction and storage temperature −55 to +150 °C) apply to the device.

CAD (KiCad official)

  • Symbol: ESD9C3.3ST5G
  • Footprint: Diode_SMD:D_SOD-923
  • 3D model: SOD-923 (KiCad packages3D, STEP)
  • 3D model files: esd9c3-3st5g-etched.step / esd9c3-3st5g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd9c3-3st5g.step / esd9c3-3st5g.glb are the bare package body.
