ProTek Devices™ has introduced two new steering diode / transient voltage suppressor arrays (TVS array) designed for electrostatic discharge (ESD) circuit protection in various popular high-speed interfaces. Such interfaces include USB, DVI and HDMI, Gigabit Ethernet, IEEE 1394 FireWire, and SATA and PCIe.
The first new combo steering diode TVS array is the PLR0502-6, which has an ultra-low capacitance of 0.7pF typical (max I/O to I/O). It meets IEC standards 61000-4-2 (ESD), air ±15kV, contact ±8kV; 61000-4-4 (EFT), and 61000-4-5 (surge): 3A, 50W, 8/20 micro seconds. The component has a low clamping voltage and low leakage current. It provides unidirectional configuration and protects two I/O ports and a power supply. The PLR0502-6 is also RoHS and REACH compliant.
The PLR0506LP is also an ultra-low capacitance - 0.4pF typical (I/O to I/O) - combo steering diode TVS array. It also meets various IEC standards requirements, such as 61000-4-2 (ESD): air – 15kV, contact – 8kV; 61000-4-4 (EFT): 40A – 5/50ns; and 61000-4-5 (lightning): 4A – 8/20 micro seconds. It provides ESD protection of > 25 kilovolts. Like the PLR0502-6, the PLR0506LP is also RoHS and REACH compliant. This device, in conjunction with passive components integrated into a TVS / filter network, can also be used for electromagnetic interference / radio frequency interference (EMI / RFI) protection.
The PLR0502-6 is provided in a molded JEDEC SC-89 package and has an approximate weight of only 3.05mg. The PLR0506LP is provided in a molded JEDEC DFN-8 package and has an approximate weight of only seven milligrams.
Other key mechanical characteristics for these circuit protection components include lead-free pure-tin plating (annealed) with a solder reflow temperature, pure-tin, of Sn, 100: 260-270 degrees Celsius. They also both have a flammability rating of UL 94V-0.
The devices are offered on 8mm tape and reel, per EIA standard 481, in minimum quantities of 3,000.
