Last week 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. The original press release can be read here.
