Ultra-flat circuits could have unique properties
The old rules don't necessarily apply when building electronic components out of two-dimensional materials, according to scientists at Rice University.The Rice lab of theoretical physicist Boris Yakobson analysed hybrids that put 2D materials like graphene and boron nitride side by side to see what happens at the border. They found that the electronic characteristics of such "co-planar" hybrids differ from bulkier components.
Bus converter suits datacomms and server & storage systems
Ericsson Power Modules has announced the BMR458, a 3rd gen 3E quarter-brick advanced bus converter that delivers industry-leading performance to system architects developing equipment for ICT applications, including datacomms and server and storage systems.
Super barrier rectifier suits retrofit MR16 LED lamps
Designed to deliver a low forward-voltage drop in a small form factor while maintaining low reverse-current leakage, the SBRT3M40P1 Trench Super Barrier Rectifier (SBR) has been introduced by Diodes Incorporated. This capability addresses requirements for input bridge rectifiers in SSL applications focused on 12VAC LED retrofit lamps, which provide a more efficient and longer life alternative to popular MR16 halogen bulbs.
Graphene nano-device could increase energy efficiency
A graphene-based electrical nano-device has been created which could substantially increase the energy efficiency of fossil fuel-powered cars. The nano-device, known as a 'ballistic rectifier', is able to convert heat which would otherwise be wasted from the car exhaust and engine body into a useable electrical current. Parts of car exhausts can reach temperatures of 600 degrees Celsius. The recovered energy can then be used to power additional a...
SiC power devices accelerate automotive electrification
STMicroelectronics has announced advanced high-efficiency power semiconductors for EVs & HEVs with a timetable for qualification to the AEC-Q101 automotive standard. In EVs and HEVs, where better electrical efficiency means greater mileage, ST’s latest SiC technology enables auto makers to create vehicles that travel further, recharge faster and fit better into owners’ lives.
Low loss 3-phase suitable diode bridge rectifier reduces heat
Linear Technology Corporation announces the availability of a low loss 3-phase suitable diode bridge rectifier reference design, demonstrated on evaluation board DC2465. Conventional 3-phase rectifiers employ six diodes, but the diodes drop voltage and dissipate significant power at just a few amperes of load current. This requires costly heat sinking and active cooling solutions that complicate thermal design and increase solution size.
Rectifier diodes meet wide range of applications
An increased range of HY Electronics rectifier diodes and bridge rectifiers is now available to order from JPR Electronics. The extensive HY product range includes rectifier diodes, bridge rectifiers, Schottky barrier rectifiers, power mosfets, fast recovery Epitaxy diodes, 3-phase rectifiers, transient voltage suppressors, LED driver modules (CLD) and IGBT modules.
SMD schottky barrier rectifiers save space
Vishay Intertechnology has introduced six surface-mount Schottky barrier rectifiers in the low-profile DO-219AB (SMF) package. Providing space-saving alternatives to SMA and SOD123W packages, the Vishay Semiconductors SS1FL3, SS2FL3, SS1FL4, SS2FL4, SS1FH10 and SS2FH10 provide reverse voltages of 30, 40 and 100 V and offer high current ratings up to 2A for automotive and commercial applications and industrial applications such as freewheeling dio...
