Low-profile two-color chip LEDs are ultra-compact
The industry’s smallest class (1608 size) of two-color chip LEDs, dubbed SML-D22MUW, features a special design that improves reliability along with a backside electrode configuration that supports high-resolution displays. Conventional numerical displays use a single color to indicate numbers, but there is a growing need to change the color to make it easier to recognize […]
SiC power modules carry 1,200-V 400/600-A ratings
New 1,200-V 400/600-A-rated full SiC power modules [BSM400D12P3G002/ BSM600D12P3G001] are optimized for inverters and converters in solar power conditioners, UPS, and power supplies for industrial equipment. Developed by Rohm, the BSM600D12P3G001 can handle 600 A by utilizing a new package featuring an original internal structure and optimized heat radiation design, enabling support for higher power […]
Gallery: APEC 2017 — Hot markets moving cool speed ahead
A considerable segment of the products and technology at the Applied Power Electronic Conference (APEC) 2017 would have fit right in or neatly alongside a 2017 auto and telecom show. Power electronics for EV on- and off-board chargers were making headlines, as well as electronics addressing the high-speed server markets. Silicon Carbide (SiC) and Gallium […]
Reference boards help evaluate high-voltage fan motor drivers
ROHM has recently announced the availability of reference boards designed to evaluate its high voltage fan motor drivers that achieve greater efficiency and simplify inverter configuration in home appliances such as ceiling fans and ACs. Of the total power consumed worldwide, it has been noted that close to 50% is used to drive motors, and […]
SiC Schottky barrier diodes feature low forward voltage, high surge resistance
ROHM has recently announced the availability of 3rd generation SiC Schottky Barrier Diodes (SBDs) optimized for power supply PFC circuits in servers and high-performance PCs. The SCS3 series adopts a new structure that improves upon the industry-low VF characteristics of ROHM’s 2nd Generation SiC SBDs (1.35V @ 25C) while providing increased surge resistance. This contributes […]
Formula E racers lighten up thanks to SiC inverter technology
The first race of the new 2016/2017 Formula E season in Hong Kong featured an inverter built with silicon-carbide power semiconductors. The inverter helps power a car raced by the Venturi Formula E team, sponsored by the Japanese semiconductor ROHM. Formula E, of course, is an open-cockpit race series styled after Formula 1 but using […]
