ProTek Devices' SRV05-4-A Offers Circuit Protection in Smartphones, Computing Interfaces and More

ProTek Devices introduced a new ultra-low capacitance steering diode / transient voltage suppressor array (TVS array) targeting circuit protection in a variety of applications that include Gigabit Ethernet; smartphones and other portable electronics; and video card, USB and DVI interfaces. The SRV05-4-A is designed for electrostatic discharge (ESD) protection of > 25 kilovolts and offers protection for up to four lines.

ProTek Devices' SRV05-4-A meets several IEC standards including: 61000-4-2 (ESD): air 15kV, contact 8kV; 61000-4-4 (EFT): 40A, 5/50ns; and 61000-4-5 (surge): 12A, 8/20 micro seconds - level 2 (line-GND) and level 3 (line-line). The component can clamp the effects of electrical fast transients (EFT) on the power bus. It combines eight low-capacitance steering diodes for up to four individual data or transmission lines and one TVS diode for power bus protection. The SRV05-4-A features 200 watts peak pulse power per line, (typical = 8/20 micro seconds) and a low clamping Voltage. It has a rated stand-off voltage of 5.0 volts and minimum breakdown voltage of 6.0 volts. Its ultra-low capacitance (typical) is 3.5pF I/O to GND, 2.0pF I/O to I/O. The new part is RoHS and REACH compliant.

Mechanical features include a space-saving molded JEDEC SOT-23-6 package configuration that minimizes lead inductance to prevent overshoot voltages during high ESD current events. The approximate weight is 16 milligrams. Other mechanical characteristics of interest include lead-free nickel palladium gold plating, a solder reflow temperature of 260 to 270 degrees Celsius, and a flammability rating of UL 94V-0.

Pricing and Availability
ProTek Devices' SRV05-4-A is now available in mass quantities. Pricing varies by amounts starting at a minimum quantity of 3,000 components provided in 8mm tape and reel, per EIA standard 481. Interested parties should inquire with a local authorized distributor or directly with ProTek Devices for pricing details. These full contact details and a data sheet for the SRV05-4-A can be found on the ProTek Devices website.
