T-Filter with TVS Diode Array For EMI Filtering and ESD Protection PROTECTION PRODUCTS Description 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 device has very low insertion loss in the pass band (to approximately 10MHz) and good attenuation at high frequencies (approximately 100MHz to 1GHz). Each line Features two stages of TVS diode protection. The TVS diodes provide effective suppression of ESD voltages in excess of 15k V (air .. discharge) and 8k V (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 of the STF701 minimizes required board space and increases system reliability. The STF701 is suitable for use in portable munications devices such as cellular handsets and accessory kits.
