TVS/Filter Combination Network

Thu, 08/30/2001 - 9:28am
ProTek Devices has introduced the STF701, a TVS/filter combination network designed to reduce EMI/RFI noise on data I/O ports and provide transient voltage protection for handheld electronic systems such as PDAs, notebooks and pagers. Ideal for both protection and noise suppression on transceivers operating up to 100 MHz this device is designed for use on digital circuits less than 5 volts.

The STF701 is packaged in an industry So-8 package with a common ground pin for both TVS/filter networks. Each package consists of two networks, each to be used to common mode protection against electro-static discharge (ESD) in accordance to IEC 61000-4-2.

Regardless of the source of the transient threat, the STF701 has equal input and output protection capabilities. The individual TVS components will protect against an ESD pulse of greater than 25 kV, SPICE model and parameters are available for circuit simulation.
