ESD3B3CM

MDD Microdiode Semiconductor · ESD And Surge Protection (TVS/ESD) · SOD-323

ESD3B3CM from MDD Microdiode Semiconductor, 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 1 passive One terminal of the bidirectional TVS/ESD protection diode, which the datasheet rates for a 3.3 V reverse working voltage and ±30 kV IEC 61000-4-2 air and contact ESD; the datasheet does not name this pin or assign it a separate function.
2 2 passive The other terminal of the bidirectional TVS/ESD protection diode, which the datasheet rates for a 3.3 V reverse working voltage and ±30 kV IEC 61000-4-2 air and contact ESD; the datasheet does not name this pin or assign it a separate function.

CAD (KiCad official)

  • Symbol: ESD3B3CM
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: esd3b3cm-etched.step / esd3b3cm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd3b3cm.step / esd3b3cm.glb are the bare package body.
