Steering diode/arrays deliver ESD circuit protection for popular computing interfaces

08-05-2018 | Protek | Semiconductors

ProTek Devices has introduced two new steering diode/transient voltage suppressor arrays for electrical circuit protection in multiple computing interfaces, such as Gigabit Ethernet, HDMI and USB. The two new parts, together 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 5V-rated standoff voltage, and the PLR3304PLCN, with a 3.3V-rated standoff voltage. Other ideal applications include DVI interfaces, FireWire, SATA and PCIe interfaces, high-speed data line ESD protection, and IEEE 1394 to 3.2Gbps.

The new TVS arrays provide an ultra-low capacitance of 1.5pF max (I/O to GND) and 1.37pF typical for 0Vdc. They are rated at 250W 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 >25kV and low-leakage current is <0uA. They protect four lines and are also RoHS and REACH compliant. The parts also have a flammability rating of UL 94V-0.
