Toshiba TLP250H optocoupler directly drives a power transistor

11.01.2013

Toshiba announced the release of an optocoupler in a DIP8 package capable of directly driving an IGBT or medium power FET. Designated as TLP250H, the peak output current is +2,5A and the input current is less than 5mA. The manufacturer considers a short signal propagation time of 500 ns and an uneven propagation time of no more than 150 ns to the advantages of the novelty. Such values of these parameters help to increase the efficiency of inverter circuits.

In addition, the use of a new optocoupler will help reduce the power consumption of electronic devices, since its operating voltage range has been extended to 10-30 V (the previous model operated at a voltage of at least 15 V).

The Toshiba TLP250H optocoupler is designed for operation in the temperature range from -40°C to 125°C. Among the areas of application of the novelty, the manufacturer names industrial electronics, solar-powered home power supplies, digital electronic devices, and measuring instruments.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Nanostructure based on the moth's eye 07.08.2020

Scientists from the Vietnamese Tan Trao University and the Tai Nguyen Pedagogical University made an interesting discovery. It turns out that there are nanoscale bulges in front of the eyes of moths, the study of which promises many interesting technological advances. These bulges have incredible anti-reflective properties that allow the eye to absorb almost all of the incoming light.

Such a nanostructure will enable the development of a host of devices, from efficient solar cells to advanced X-ray emitters and smartphone displays that reduce glare. However, in addition to the pronounced optical properties, the newly discovered structure has another unique property.

Scientists have managed to build a complex nanostructure out of quartz, modeled on the eyes of a moth. The resulting transparent structure was covered with paraffin in order to isolate it from the influence of cold and humid environment. Then we conducted a series of experiments, observing the operation of the nanostructure.

The unique properties of the material are explained by the presence of many air pockets inside the nanostructure. These pockets are filled with a layer of paraffin on the surface, creating higher freezing temperatures and therefore increasing the freezing time of water droplets on the surface.

One of the main applications of open unique materials is the processing of aircraft wings. As is known, the build-up of ice on the surface of an aircraft wing significantly limits the lifting force of an air liner, and also interferes with the moving parts of the aircraft.

The technology can also find application in power transmission systems. Vietnamese experts have also determined that the discovered unique nanostructure is ideal for optical applications such as eyeglasses. This is obvious given the high transparency and anti-reflective properties.
