New Toshiba Low Voltage MOSFETs

14.11.2014

Toshiba Electronics Europe (TEE) announced that its high efficiency low voltage MOSFETs are now also available in ultra-compact DSOP Advance packages. The new cases support dual-sided cooling for significantly improved heat dissipation. This enables high-density device designers to minimize PCB temperatures and improve device performance without increasing board footprint.

The DSOP Advance package occupies 5mm x 6mm of PCB space, just like devices with the SOP Advance package. In comparative tests, operating temperatures of 30 V MOSFETs (with appropriate heatsinks) at currents above 30 A decreased by more than 34%. Moreover, in a number of designs, the reduced thermal resistance of the DSOP Advance case allows you to abandon the heatsink.

Toshiba intends to use DSOP Advance packages for its existing (UMOS VIII-H) and new (UMOS IX-H) MOSFET families. These transistors combine an industry-leading RDS(ON) rating with low output capacitance for ultra-high switching efficiency. Initially, a range of MOSFETs with voltage ratings from 30V to 100V will be available in DSOP Advance packages.

Intended applications for MOSFETs in the new DSOP Advance packages include high-density, high-performance power switches, including synchronous power supply converters for servers and telecommunications equipment, and power tools.

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Recyclable printed circuit boards 03.05.2024

Electronics play a key role in today's world, but the accompanying rise in e-waste is putting the environment at risk. In response to this problem, researchers at the University of Washington have developed an innovative technology that could change conventional wisdom about circuit board recycling. A team led by scientists from the University of Washington has created a vitrimer printed circuit board that has the unique ability to be recycled multiple times. Using advanced environmentally friendly polymers, the researchers developed a material that can be turned into a jelly-like substance using a special solvent. This opens the way for PCBs to be reused and recycled without significant loss of quality. Vitrimer printed circuit boards (vPCBs) represent significant advances in environmental sustainability. Unlike conventional plastics, which are susceptible to degradation during repeated recycling, jelly-like vitrimer retains its ... >>

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Color monitor with electronic ink 05.08.2023

Dasung Technology from China has introduced an innovative monitor that combines a color matrix with electronic ink (E-Ink) technology.

This monitor becomes the first in the world to embody the color gamut based on E-Ink technology. The device incorporates a 25,3-inch Kaleido RGB panel inside a slim body.

The display resolution of the monitor is 3200 x 1800 pixels, capable of transmitting 4096 shades of colors.

The unique Dasung X-Color Filter technology implemented in the device improves the contrast and brightness of the image, and also provides the ability to adjust the level of darkening of the text. This monitor is based on the same typical matrix as e-books.

The enjoyment of this Dasung Technology Super Low Power Display promises to attract many users. However, it should be noted that this device has some limitations compared to traditional monitors: the absence of a backlight, which makes the image on the screen less saturated and more blurry.
