TVS Array for Circuit Protection in Popular Data Interfaces


The PLR0521U TVS Array Provides Circuit Protection Against ESD and EFT for Gigabit Ethernet, USB, HDMI and More

TEMPE, Ariz. – ProTek Devices introduced an ultra-low-capacitance transient voltage suppressor array (TVS array) for circuit protection in popular data interface connections such as Gigabit Ethernet, FireWire, USB 2.0 and 3.0, and HDMI 1.4 and 2.0. The very low capacitance for the new PLR0521U TVS array is 0.8 pF max (typical).

The PLR0521U protects these interfaces from the damaging effects of electrostatic discharge (ESD) and electrical fast transients (EFT). It meets or exceeds several IEC standards. The standards are 61000-4-2 (ESD): air ±15kV, contact ±8kV; 61000-4-4 (EFT); and 61000-4-5 (surge): 4A, 80W, 8/20 micro seconds.  The TVS array also boasts a low clamping voltage and protects one unidirectional line. Peak pulse power is 80 watts (typical at 8/20 micro seconds). The rated standoff voltage is 5.0. It is also RoHS and REACH compliant.

Mechanical, Packaging and Availability Information

The PLR0521U TVS array is now available and is provided in a molded DFN-2 package with an approximate weight of only 2 milligrams. Other key mechanical characteristics include lead-free Ni/Pd/A plating and a solder reflow temperature of (pure-tin - Sn, 100) 260 to 270 degrees Celsius. It has a flammability rating of UL 94V-0. It is delivered on 8mm tape and reel, per EIA standard 481, in minimum quantities of 10,000.
