ProTek Devices 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 and more. The series consists of five components with rated stand-off voltages between 5-24 volts. The components are also packaged in an ideal low-profile miniature DFN-2 package.
It’s possible other voltages can be provided upon request. Such a request can be made directly with ProTek Devices. 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. This series gracefully aids design engineers in addressing this concern.
ProTek Devices’ GBLCxxCDN series is ideal for use as a replacement for multilayer varistors (MLV ). It protects one power or I/O port and offers ESD protection at > 25kV. It also provides a low clamping voltage and is RoHS and REACH compliant. In addition to the low-profile miniature JEDEC DFN-2 package, the series components have an approximate weight of only 0.8 milligrams. Other important mechanical characteristics include lead-free pure-tin plating (annealed) and a solder reflow temperature of (pure-tin – Sn, 100) 260 to 270 degrees Celsius. The flammability rating is UL 94V-0. Operating and storage temperature is -55 to 150 degrees Celsius.
Pricing and Availability
ProTek Devices’ GBLCxxCDN series of circuit protection components is now available in mass quantities. Pricing varies by amounts. Interested parties should inquire with a local authorized distributor/representative or directly with ProTek Devices. The series is provided in 5,000 minimum quantities via eight millimeter tape and reel, per EIA standard 481. A data sheet for the GBLCxxCDN series can be download from the ProTek Devices website.
