Optoisolators - Transistor, Photovoltaic Output・OverviewOptoisolator, also known as optoelectronic isolator, photocoupler, or optical isolator, is an electronic component that transmits electrical signals between two isolated circuits by using light. Generally, it consists of an infrared LED that is optically coupled to a photodetector. The LED emits a light beam when current flows through it, which is detected by the photodetector and converted back into an electric current. The optoisolator technology provides isolation between input and output circuits, helps reduce electromagnetic interference (EMI), and is ideal for applications that require electrical noise suppression.・HMHA2801C Application FieldHMHA2801C is a type of optoisolator designed for use in industrial, automotive, and consumer applications. It provides electrical isolation between input and output circuits and is suitable for use in interface, feedback, and control circuits. HMHA2801C has an insulated non-concentrative gate and open-collector output, and features a wide voltage operation range from 2.7-24V. It also offers low distortion and high current carrying capacity, making it an ideal choice for high-power applications.・HMHA2801C Working PrincipleThe working principle of the HMHA2801C is based on the optoisolator technology. It is composed of a wide-junction media access control (MAST) transistor, an infrared LED, and a photodiode. When current passes through the LED, a beam of light is emitted which is detected by the photodiode. The photodiode then converts it into an electric current and passes it to the MAST transistor which is the output of the optoisolator. The MAST transistor then amplifies the input current and switches the signal. The output of the optoisolator is then available at the open-collector output.・HMHA2801C AdvantagesThe HMHA2801C has several advantages which make it suitable for a wide range of applications. It has a wide voltage operating range from 2.7-24V and a current carrying capacity up to 1.5A. It also provides high insulation barrier which is up to 4kV peak and 500MΩ@500V input-output isolation resistance. Furthermore, it is designed with low distortion which makes it ideal for use in feedback and control circuits. Lastly, the operating temperature range of the HMHA2801C is -40℃ to 80℃, making it suitable for use in extreme temperatures.・ConclusionThe HMHA2801C is an optoisolator which is designed for use in industrial, automotive, and consumer applications. It provides electrical isolation between input and output circuits and is suitable for use in interface, feedback, and control circuits. It features a wide voltage operation range from 2.7-24V, low distortion, high current carrying capacity, and a wide operating temperature range from -40℃ to 80℃.
