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

TEMPE, Ariz. – Sept. 14, 2015 – ProTek Devices™ today 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.

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
