New series of ultra-low capacitance transient voltage suppressor arrays

ProTek Devices has introduced a new series of ultra-low capacitance transient voltage suppressor arrays (TVS arrays) for over-voltage circuit protection in applications such as smartphones, Ethernet, USB and more. The series consists of five components with rated stand-off voltages between 5-24V. Other voltages are available on request. The components are also packaged in a low-profile miniature DFN-2 package. The GBLCxxCDN series' capacitance is rated at 3pF (typical). Components from the series are available in a bidirectional configuration. They are rated at 350W 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. The device exceeds level four by handling 10kV contact and 25kV air discharges. It is 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 aids design engineers in addressing this concern, says the company. The GBLCxxCDN series is seen as ideal for use as a replacement for multilayer varistors (MLV [0805]). 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 mechanical characteristics include lead-free pure-tin plating (annealed) and a solder reflow temperature of (pure-tin - Sn, 100) 260C to 270C. The flammability rating is UL 94V-0. Operating and storage temperature is -55C to 150C.
