ProTek Devices Intros Two Series of Circuit Protection Components for Computing Interfaces

Release Date: May 28 2019

ProTek Devices has introduced two new series of steering diode / TVS arrays for surge, electrostatic discharge and other circuit protection in computing applications such as Ethernet ports, set-top boxes, and other computing ports and interfaces.

The PSRDAxx-4A and PSRDAxx-6A series are low capacitance multi-line steering diode / transient voltage suppressor arrays. The PSRDAxx-4A is also suited to protect video card applications while the PSRDAxx-6A is also suited for industrial controls. They provide board-level circuit protection for standard TTL and CMOS bus line applications against the damaging effects of ESD, tertiary lightning and switching transients.

Both series have a peak pulse power rating of 500 Watts for an 8/20 micro second waveshape. They also are compatible with various IEC standards that include 61000-4-2 (ESD): air - 15kV, contact - 8kV; with 61000-4-4 (EFT): 40A - 5/50ns; with 61000-4-5 (surge): 24A, 8/20 micro seconds - level 2 (line / ground) and level 3 (line-line). The PSRDAxx-4A features unidirectional configuration and the PSRDAxx-6A features bidirectional configuration. Both series are available in multiple voltages. The PSRDAxx-4A series protects up to four I/O ports and the PSRDAxx-6A series protects up to six lines. Both series also offer low capacitance of 5pF and are RoHS and REACH compliant.

Mechanical, Packaging and Availability Information
These steering diode / TVS array series are now available in a molded JEDEC SO-8 package with an approximate weight of just 70 milligrams. Other key mechanical characteristics include lead-free pure-tin plating (annealed) and a solder reflow temperature (pure-tin - Sn, 100) of 260-270 degrees Celsius. The new steering diode / TVS array series also have a flammability rating of UL 94V-0. The steering diode / TVS array components are provided on 12mm tape and reel per EIA standard 481 in quantities starting at 1,000.

Pricing information and purchasing details can be had by contacting any authorized worldwide distributor, representative, or directly with ProTek Devices.
