ProTek Devices has introduced an ultra-low capacitance steering diode / TVS array for circuit protection against electrostatic discharge and surge transient voltages in Gigabit Ethernet, HDMI, USB, and other computing interfaces. The new component provides protection for six rail-to-rail data lines, making it optimal for applications with minimal board space.

The PLR0506LC is specifically suited to protect high-speed data port like USB Type-C, but is also applicable for Gigabit Ethernet, FireWire, HDMI 1.4 and HDMI 2.0, SATA, and other PCIe interfaces. It is compatible with IEC standards 61000-4-2 (ESD): air ±15kV, contact ±8kV; with 61000-4-4 (EFT): 40A - 5/50ns; and with 61000-4-5 (lightning): 4A - 8/20 microseconds.

The typical capacitance I/O to ground is 0.4pF and I/O to I/O is 0.25pF at 0Vdcc, 1MHz. The PLR0506LC delivers ESD protection up to 25 kilovolts and has a low clamping voltage of 22V at 4A. Its ultra-low capacitance is 0.25pF typical, I/O to I/O. The PLR0506LC is also RoHS and REACH compliant.

ProTek Devices’ PLR0506LC is provided in a molded JEDEC DFN-8 package with an approximate weight of just seven milligrams. Other mechanical and packaging characteristics include lead-free pure-tin annealed plating and a solder reflow temperature (pure-tin - Sn, 100) of 260 to 270oC. Operating and storage temperatures are -55 to 150oC. And the flammability rating is UL 94V-0.

This steering diode / TVS arrays is provided on 8mm tape and reel, per EIA Standard 481, in quantities starting at 3,000 units. Pricing information and purchasing details can be obtained by contacting any authorized worldwide distributor, representative, or directly with ProTek Devices. These sales sources are available throughout Europe, North America, Asia, South America, and more. Full contact information for all regions can be found at the company website.

ProTek Devices’ components are used worldwide in a variety of applications to guard against various electrical transients that can damage electronics. This includes in aerospace subsystems, automotive subsystems, computing interfaces, consumer electronics, industrial and instrumentation equipment, medical devices, military subsystems, and in networking and communications equipment.
