New ultra low-capacitance steering diode / transient voltage suppressor array

Designed to deliver circuit protection in Gigabit Ethernet applications, smartphones, video card interfaces and more - ProTek Devices has introduced a new ultra low--capacitance (0.9pF) steering diode / transient voltage suppressor array (TVS array). The PAZC099 is rated for 5V applications with 100 watts peak pulse power per line (8/20 micro seconds). It is also ideal for circuit protection in USB 1.0, 2.0 and 3.0 applications, DVI interfaces and other portable electronics, says the company. The PAZC099 provides surge suppression and electrostatic discharge (ESD) protection in such high-speed data line applications. ESD protection is > 25kV. It combines eight ultra-low capacitance steering diodes for up to four individual data or transmission lines. The device has one TVS diode for the power bus and meets or exceeds various IEC standards: 61000-4-2 (ESD): air 15kV, contact 8kV; 61000-4-4 for electrical fast transients (EFT): 40A, 5/50ns; and 61000-4-5 (surge). In addition, the PAZC099 provides a low clamping voltage and is RoHS and REACH compliant. The part is offered in a space-saving SOT-23-6 package configuration. The small package size minimizes lead inductance, preventing overshoot voltages during high ESD current events. ProTek Devices recommends the PAZC099 be mounted near the connector on the PCB. The approximate weight of the component is just 16 milligrams. Other key mechanical characteristics include lead-free nickel palladium gold plating and a UL 94V-0 flammability rating. The solder reflow temperature (nickel-palladium-gold: Ni/Pd/Au, 96/3.5/0.5) is 260C to 270C. Operating and storage temperature is -55C to 150C.
