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

Common-mode ElectroMagnetic Interference (EMI) filters with integrated bidirectional ElectroStatic Discharge (ESD) protection for one, 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. Table 1. Product overview
