Two New Components Guard Against Damaging Electrical Events in Useful Computing Interfaces, Such as Gigabit Ethernet, HDMI, USB, and More
Steering Diode/TVS Arrays Deliver Electrical, ESD Circuit Protection for Popular Computing Interfaces
ProTek Devices has introduced two new steering diode / transient voltage suppressor arrays for electrical circuit protection in various computing interfaces, such as Gigabit Ethernet, HDMI and USB. The two new parts, in conjunction with passive components integrated into a TVS / filter network, can also be used for electromagnetic / radio frequency interference protection.
The new components are the PLR0504PLCN, with a 5.0 volt rated standoff voltage, and the PLR3304PLCN, with a 3.3 volt rated standoff voltage. Other suitable applications include DVI interfaces, high-speed data line ESD protection, FireWire, SATA and PCIe interfaces, and IEEE 1394 to 3.2Gbps.
The new TVS arrays provide ultra-low capacitance of 1.5pF max (I/O to GND) and 1.37pF typical for 0Vdc. They are rated at 250 Watts peak pulse power per line for an 8/20 micro second waveshape. Both components meet or exceed IEC standards requirements for 61000-4-2 (ESD), 61000-4-4 (EFT) and 61000-4-5 (surge). ESD protection is > 25 kilovolts and low-leakage current is < 0.5 microampere. They protect four lines and are also RoHS and REACH compliant. The parts also have a flammability rating of UL 94V-0
Mechanical, Packaging and Availability Information
The PLR0504PLCN and PLR3304PLCN TVS arrays are now available and are provided in a molded DFN-10 package with an approximate weight of only seven milligrams. Other key mechanical characteristics include lead-free pure-tin plating (annealed) and a solder reflow temperature of (pure-tin - Sn, 100) 260 to 270 degrees Celsius. The GBLCxxCIDFN series has a flammability rating of UL 94V-0. It is delivered on 8mm tape and reel, per EIA standard 481, in minimum quantities of 3,000.
