New TVS Array Protects High-Speed Interfaces

Protection from transients for FireWire, USB1.1/2.0, 10/100/1000 BaseT Ethernet, and other high-speed interfaces is available with the ET723, a new, low-capacitance, 6-line steering diode array. With a capacitance of less than 5 pF, the TVS array is said to have little effect on signal integrity while protecting the circuitry from transients. The device is able to protect up to six I/O lines by clamping the transient voltage to the power source lines or ground. Designed to meet IEC 61000-4-2 (ESD), 61000-4-4 (EFT) and 61000-4-5 (lightning surge) transient specs, the diodes can be connected in parallel for increased transient current protection. Price is $0.78 each/5,000. For more details, contact Dave Hutchins at PROTEK DEVICES, Tempe, AZ. (602) 431-8101.
