TVS arrays guard against ESD strikes in high-speed interfaces

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

The company’s distributor and representative channels are available worldwide across the USA, Europe, Asia, Latin America and more. This contact information can be found at the company website.
