![]() ![]() The High-frequency response of this diode gives good results It allows more current, so used in high power consumption applications It allows less current, so used in less power consumption applications The linear response is high, so used to measure the exact measurement of light It is not responsive more to incident light The main difference between photodiode and phototransistor includes the following. Difference between Photodiode and Phototransistor And also signifies the difference within the base current through the difference within the intensity of light. In the above graph, we can notice that the current increases through the light intensity when falls on the base terminal. The current within the collector region changes through the wavelength as well as the light intensity. The current within the collector terminal enhances through the intensity of light. From the following graph, we can notice how the current flow in the collector region changes with the incident light intensity. In the following graph, the x-axis signifies the applied voltage at the collector-emitter region of the transistor whereas the y-axis signifies the collector current supplies throughout the device in mA. The characteristics of a phototransistor are discussed below. The graph below shows the magnitude of current increases along with the intensity of light. The energy of light drops on the junction of the collector to base then it generates the majority charge carriers and adds the flow of current toward the reverse saturation current. Whenever no light ray drops on the transistor’s surface, then a little reverse saturation current will induce on top of the phototransistor due to the fewer minority charge carriers. The junction of the emitter-base is connected in forwarding bias whereas the collector-base region is connected in the reverse biased. ![]() Earlier, germanium and silicon materials are used for constructing this phototransistor. The construction of the phototransistor is quite similar to the ordinary transistor. *This information is for general informational purposes only, we will not be liable for any loss or damage caused by the above information.At last, the arrangement of a phototransistor can be done in a metallic box & a lens is placed at the top of the box to absorb the incident radiation. The company's legacy continues through its subsidiaries and its technology and products continue to be used around the world. ![]() Motorola was one of the pioneers of the mobile phone industry and has a rich history of innovation and technological advancements. The company provides a wide range of products including two-way radios, mobile computing devices, and network infrastructure equipment. Motorola Solutions focuses on public safety and commercial and industrial communication solutions. Motorola Mobility was later acquired by Google in 2012, and is now a subsidiary of Lenovo. In 2011, Motorola split into two separate companies: Motorola Mobility and Motorola Solutions. Throughout its history, Motorola was known for its innovation in the field of telecommunications, including the development of the world's first commercially available cellular telephone, the DynaTAC, and the world's first two-way pager, the Pageboy. It was headquartered in Schaumburg, Illinois and was one of the largest providers of mobile phones, telecommunication equipment, and semiconductors. was an American multinational telecommunications company that was founded in 1928. ![]()
