Super Barrier Rectifier from Diodes Incorporated Optimized for Solid-State Retrofit MR16 LED Lamps

Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic, analog and mixed-signal semiconductor markets, today introduced the SBRT3M40P1. This Trench Super Barrier Rectifier (SBR®) has been optimized to deliver a low forward-voltage drop in a small form factor while maintaining low reverse-current leakage. This capability addresses requirements for input bridge rectifiers in solid-state lighting (SSL) applications focused on 12V AC LED retrofit lamps, which provide a more efficient and longer life alternative to popular MR16 halogen bulbs.

AVX Releases Upgraded Simulation Software For Its Advanced SMPS MLCCs

Featuring new products, updated links to the latest datasheets on the new AVX website, & product photographs designed to help engineers better visualize product selections, SpiCALCI 10 simulates performance characteristics & parameters for AVX’s advanced SMPS MLCCs

AVX Corporation, a leading manufacturer of passive components and interconnect solutions, has released a new version of its SpiCALCI simulation software, an engineering tool that calculates performance characteristics and parameters for its advanced switch mode power supply (SMPS) multilayer ceramic capacitors (MLCCs) to help electrical design engineers select the part that will best satisfy their application criteria. SpiCALCI 10, which replaces the previous version, features all of the new SMPS MLCCs that AVX has introduced over the past 18 months (many of which are sole-sourced), in addition to updated links to the latest datasheets on the new AVX website, and product photographs designed to help engineers better visualize product selections. Other new features include an enhanced part selection process that makes it easier to find a valid part, and the option to view and save the output information that is used to generate graphs.

New 600 V SiHJ8N60E and 650 V SiHJ6N65E and SiHJ7N65E E Series MOSFETs in PowerPAK® SO-8L Increase Reliability and Reduce Package Inductance

Advantages of Using Silicon Carbide in Power Electronics

The advantages of using SiC in power electronics is the focus of a large number of semiconductor news studies and reports.  These reports prove just how advantages using SiC can be when designing power electronics.

Although silicon offers numerous benefits and advantages in power MOSFETs, it also displays some limitations that are characteristic to silicon material properties.  Properties like low thermal conductivity, low bandgap energy, and limitations in switching frequencies.  Power semiconductor devices, however, that are made with silicon carbide (SiC), don’t possess those types of material limitations. 

Complete Power Conversion Platform from Analog Devices Offers Processing, Sensing, and Gate Driving Solutions
