ProTek Devices has introduced two new steering diode/transient voltage suppressor (TVS) 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 and radio frequency interference protection.
The new components are the PLR0504PLCN, with a 5,0 V rated standoff voltage, and the PLR3304PLCN, with a 3,3 V rated standoff voltage. Other suitable applications include DVI interfaces, high-speed data line ESD protection, FireWire, SATA and PCIe interfaces, and IEEE 1394 to 3,2 Gbps.
The arrays provide ultra-low capacitance of 1,5 pF max (I/O to GND) and 1,37 pF typical for 0 V d.c. They are rated at 250 W peak pulse power per line for an 8/20 microsecond 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 kV and low-leakage current is less than 0,5 μA. They protect four lines and are also RoHS and REACH compliant.
