About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

Automotive-Qualified Qspeed Silicon Diodes Feature Lowest Qrr for Efficient, High-Switching-Speed Designs

600 V 12 A diodes can replace SiC parts in automotive applications

Power Integrations (Nasdaq: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today announced its 600 V 12 A Qspeed diode, delivering the industry’s lowest reverse recovery charge (Qrr) for a silicon diode. With a Qrr of just 14 nC at 25 °C, it improves efficiency of the PFC stage of on-board chargers and significantly reduces the thermals of the PFC MOSFETs. The AEC-Q101-qualified QH12TZ600Q offers the same low-switching loss performance of a silicon carbide (SiC) device without the disadvantages of moving to more expensive technology.

Edward Ong, senior product marketing manager at Power Integrations said: “The Qrr of these new Qspeed diodes is half that of the next best ultra-fast silicon diodes, resulting in very high system efficiency. This is particularly important for automotive on-board charger applications that require higher switching frequency to reduce volume and weight, and enables the Qspeed diodes to replace SiC devices.”

The QH12TZ600Q uses merged PiN and Schottky diode technology to achieve high performance. Its smooth reverse recovery current transition characteristics not only increase efficiency, but also reduce EMI and peak reverse voltage stress, eliminating the need for snubbers when used as output rectifiers in on-board chargers. Devices are available in the compact, 2.5 kV isolated TO-220 package which enables direct mounting to metal heat sinking, facilitating excellent thermal performance.

Availability & Resources

The new 600 V 12 A Qspeed diodes are priced at $1.17 in 10,000-piece quantities. For further inquiries contact a Power Integrations sales representative or one of the company’s authorized worldwide distributors: Digikey, Farnell, Mouser, and RS Components.
