TVS Arrays with Sub-picoFarad Capacitance for High-Speed Interfaces

July 31, 2017 by Paul Shepard

ProTek Devices™ has introduced two new steering diode / transient voltage suppressor arrays (TVS array) designed for electrostatic discharge (ESD) circuit protection in various popular high-speed interfaces. Such interfaces include USB, DVI and HDMI, Gigabit Ethernet, IEEE 1394 FireWire, and SATA and PCIe.

The first new combo steering diode TVS array is the PLR0502-6, which has an ultra-low capacitance of 0.7pF typical (max I/O to I/O). It meets IEC standards 61000-4-2 (ESD), air ±15kV, contact ±8kV; 61000-4-4 (EFT), and 61000-4-5 (surge): 3A, 50W, 8/20 micro seconds. The component has a low clamping voltage and low leakage current. It provides unidirectional configuration and protects two I/O ports and a power supply. The PLR0502-6 is also RoHS and REACH compliant.

The PLR0506LP is also an ultra-low capacitance – 0.4pF typical (I/O to I/O) – combo steering diode TVS array.  It also meets various IEC standards requirements, such as 61000-4-2 (ESD): air - 15kV, contact - 8kV; 61000-4-4 (EFT): 40A - 5/50ns; and 61000-4-5 (lightning): 4A - 8/20 micro seconds. It provides ESD protection of > 25 kilovolts.  Like the PLR0502-6, the PLR0506LP is also RoHS and REACH compliant. This device, in conjunction with passive components integrated into a TVS / filter network, can also be used for electromagnetic interference / radio frequency interference (EMI / RFI) protection.

The PLR0502-6 is provided in a molded JEDEC SC-89 package and has an approximate weight of only 3.05mg.  The PLR0506LP is provided in a molded JEDEC DFN-8 package and has an approximate weight of only seven milligrams.

Other key mechanical characteristics for these circuit protection components include lead-free pure-tin plating (annealed) with a solder reflow temperature, pure-tin, of Sn, 100: 260-270 degrees Celsius.  They also both have a flammability rating of UL 94V-0.

The devices are offered on 8mm tape and reel, per EIA standard 481, in minimum quantities of 3,000.
