TVS Array for Circuit Protection in Common Computing Interfaces


The New Steering Diode / TVS Array is Suited for ESD and EFT Circuit Protection in HDMI, USB, SATA, and PCIe

ProTek Devices has introduced a steering diode / transient voltage suppressor array (TVS array) for circuit protection in common computing interfaces like HDMI and DVI, USB, SATA and PCIe, and more. It provides an ultra-low capacitance of 0.3pF, typical for I/O to ground.

The new device part number is the PLR0504FN5. It is compatible with the IEC standards 61000-4-2 (ESD): air plus or minus 15kV and contact plus or minus 8kV, with 61000-4-4 (EFT): 40A, 5/50ns, and with 61000-4-5 (surge): 3A - 8/20 microseconds. The new component also offers ESD protection of > 25 kilovolts for four data lines. In addition, it offers low leakage current of < 0.1 microampere. ProTek Devices’ PLR0504FN5 is also RoHS and REACH compliant. Finally, at higher operating frequencies or faster edge rates, insertion loss and signal integrity are a major concern. This new device, in conjunction with passive components integrated into a TVS / filter network, can be used for EMI / RFI protection for such a scenario.

Mechanical Details and Availability Information

ProTek Devices’ PLR0504FN5 has an approximate weight of just five milligrams. The component comes in a molded DFN-5 package. Other mechanical and packaging characteristics include operating and storage temperatures of -55 to 150 degrees Celsius and lead-free pure-tin plating (annealed). The components perform with a solder reflow temperature (pure tin: Sn, 100) of 260 to 270 degrees Celsius. It also has a flammability rating of UL 94V-0.

The part is available on 8mm tape and reel, per EIA standard 481, in minimum quantities of 6,000. Pricing information and purchasing details can be obtained by contacting any authorized worldwide distributor, representative, or directly with ProTek Devices. These sales resources are available throughout North America, Europe, Asia, South America, and more. 

ProTek Devices’ circuit protection components include transient voltage suppressors, TVS diodes, steering diode TVS arrays, and other modules and components. They are used worldwide in numerous applications to guard against various electric transient surges and high voltage spikes that can damage electronics investments. 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.
