vsip10_pic

ProTek Devices has a revised data sheet for its VSIP® series of high powered multi-line transient voltage suppressor arrays (TVS arrays), which are ideal for overvoltage circuit protection in a variety of telecommunications applications. Such applications include RS-232 & RS-423 data lines; telecommunications T/R protection; ISDN, xDSL, V.34/V.90, HDLC, T1/E1 and T3/E3; low and high speed data lines such as Ethernet and Token Ring; and I/O port protection. Circuit protection covers the damaging effects of electrostatic discharges (ESD), electrical fast transients (EFT) and secondary transient threats.

The VSIP series “A” has a peak pulse power rating of 800 watts for an 8/20 microseconds waveshape. Meanwhile, the VSIP series “B” has a peak pulse power rating of 3400 Watts for an 8/20 microseconds waveshape. These devices are compatible with standards IEC 61000-4-2 (ESD): air – 15kV, contact – 8kV; with 61000-4-4 (EFT): 40A – 5/50ns; and with 61000-4-5 (surge): 24A, 8/20 microseconds – level 2 (line-gnd) and level 3 (line-line). ESD protection is > 25 kilovolts and the parts allow for a bidirectional configuration. They also boast a high surge capability and low capacitance option, all to protect 8 to 9 bidirectional lines. Some 20 components make up the series, covering rated stand-off voltages from 5.0 to 24.0 volts and minimum breakdown voltages from 6.0 to 26.7 volts. These components are RoHS and REACH compliant.

ProTek Devices’ VSIP TVS arrays are provided in a molded 10 pin plastic VSIP® package and have an approximate weight of just 1.5 grams. Other mechanical characteristics include lead-free pure-tin Plating (annealed) and a solder reflow temperature (pure-tin – Sn, 100) of 260 to 270 degrees Celsius. The flammability rating is UL 94V-0. The operating and storage temperature is -55 to 150 degrees Celsius.
