ProTek Devices today introduced a new series of ultra-low capacitance transient voltage suppressor arrays (TVS arrays) for overvoltage circuit protection in applications that include smartphones, Ethernet, USB, sensor nodes, and more. The series consists of five components with rated stand-off voltages between 5-24 Volts. The components are also packaged in a low-profile miniature DFN-2 package.

Other voltages can be provided upon request. The GBLCxxCDN series’ capacitance is rated at 3pF (typical). Components from the series are available in a bidirectional configuration. They are rated at 350 Watts peaks pulse power per line for an 8/20 microseconds wave shape. The series is also compatible with IEC standard 61000-4-2 for electrostatic discharge (ESD): air – 15kV, contact – 8kV. It actually exceeds level four by handling 10kV contact and 25kV air discharges. It’s also compatible with IEC 61000-4-4 for electrical fast transients (EFT): 40A – 5/50ns, and with IEC 61000-4-5 (surge). Design engineers are aware that at higher operating frequencies or faster edge rates, insertion loss and signal integrity are a major concern.

ProTek Devices’ GBLCxxCDN series of circuit protection components is now available in mass quantities. Pricing varies by amounts. The series is provided in 5,000 minimum quantities via eight millimeter tape and reel, per EIA standard 481.
