STF701 T-Filter

The STF701 is a low pass T-filter with integrated TVS diodes. It is designed to provide bi-directional unwanted EMI/RFI signals filtering and electrostatic discharge (ESD) protection in portable electronic equipment. Each device will provide filtering and protection for two I/O lines. The STF701 is constructed using thin-film-on-silicon technology. The devic.

Features

two stages of TVS diode protection. The TVS diodes provide effective suppression of ESD voltages in excess of 15kV (air www.DataSheet4U.com discharge) and 8kV (contact discharge) per IEC 610004-2, level 4. The clamping characteristics of the device are optimized by the use of two TVS diodes. The TVS diodes serve a dual purpose of protecting the internal capacitor and the sensitive IC connected to the line. The voltage divider action of the circuit means the voltage across the protected IC will be very close to the breakdown voltage (VBR) of the second TVS. The small size and integrated feature.
