Common-mode EMI filter for differential channels with integrated ESD protection

The devices are common-mode ElectroMagnetic Interference (EMI) filters with integrated ElectroStatic Discharge (ESD) protection for two and three differential channels. The devices are designed to provide low insertion loss for differential high-speed signals on each channel while unwanted common-mode signals are attenuated.

Each differential channel incorporates two signal lines that are coupled by integrated coils. Diodes provide protection to downstream components from ESD voltages up to ±15 kV on each signal line.

PCMF2DFN1 protects and filters two differential channels and is encapsulated in a DFN2520-9 (SOT1333-1/XSON9) plastic package.

PCMF3DFN1 protects and filters three differential channels and is encapsulated in a DFN4020-14 (SOT1334-1/XSON14) plastic package.
