SYSD03C

SY(顺烨) · IC · SOD-323

SYSD03C from SY(顺烨), in a SOD-323. 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 A1 passive Bidirectional TVS terminal 1 (I/O line to be protected, interchangeable with the other terminal), 3.3V max working voltage (VRWM), 4.0V min breakdown at 1mA.
2 A2 passive Bidirectional TVS terminal 2 (interchangeable with the other terminal, typically ground/return), 350W peak pulse power (8/20μs), ±30kV ESD contact and air.

CAD (KiCad official)

  • Symbol: SYSD03C
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: sysd03c-etched.step / sysd03c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sysd03c.step / sysd03c.glb are the bare package body.
