High-current-rated MOSFETs target EV apps
Diodes Incorporated has introduced a portfolio of automotive MOSFETs packaged in the space-saving, thermally-efficient TOLL (PowerDI1012-8) package. Capable of operating to 175°C, the 100V-rated DMTH10H1M7STLWQ, and DMTH10H2M5STLWQ, plus the 80V-rated DMTH8001STLWQ MOSFETs occupy 20% less PCB area than the TO263. These devices feature an off-board profile of just 2.4mm. This makes them ideal for use in high-reliability power […]
Thermal fuse trip temperature exceeds 175 °C
SCHURTER’S Reflowable Thermal Switch, RTS, now includes a version designed to trip at >175°C, in addition to the existing variant set to trip at >210°C. The compact thermal SMD fuse protects power semiconductors by reliably and precisely interrupting a circuit at a pre-defined temperature. Highly integrated power semiconductors used in dense circuits can lead to overheating […]
UV-C LEDs kill viruses and bacteria for disinfection systems
Würth Elektronik offers UV LEDs with emission wavelength of 275nm. This wavelength kills germs, by destroying the RNA structure of Viruses and Bacteria. Therefore, those types of LEDs are suitable for disinfection in areas where chemical components are not suitable to use. These can be devices for germicide cleaning of different surfaces, or also for […]
Inverters for green energy systems
Inverters are a key component in green energy systems ranging from solar energy systems to wind turbines. Depending on the size and sophistication of the application, inverters can produce various forms of a square wave, modified sine wave, or true sine wave outputs. Some only invert DC to AC while others are integrated with battery […]
