FOD070LR1 Application Field and Working Principle

Optoisolators – Transistor, Photovoltaic Output are widely used in many different areas with its key function of isolating low-level signals from high-level signals in order to protect sensitive electronic equipment from surges, ground loops and electromagnetic interference (EMI). The FOD070LR1 is a new type of optoisolator from fodis that utilizes photovoltaic output technology to provide maximum isolation in a compact package. It is designed to provide enhanced voltage isolation and improved noise immunity without the need for additional filtering. It has the distinction of providing a high level of signal isolation that surpasses the performance of traditional optoisolators.

The FOD070LR1 is an optoisolator with photovoltaic output which utilizes a photocoupler IC, a photosensitive diode, and a photosensitive transistor. In its simplest configuration, a photovoltaic output optoisolator consists of an input side with two LEDs, an output side with a phototransistor, and a protection diode. When the input side LEDs are illuminated by an electric current, the current is converted to a photovoltaic (light) signal which is amplified by the photocoupler IC. This amplified signal is then used to switch the output side phototransistor which in turn produces a transistor output. The photovoltaic output optoisolator utilizes the current flowing through the phototransistor to provide electrical isolation between the two sides. The phototransistor also amplifies any weak signals from the input side LEDs, thereby allowing for better signal isolation in the optoisolator.

The FOD070LR1 is typically used in applications requiring features such as automatic overload protection, low EMI susceptibility, high voltage isolation, and/or low current leakage. It is suitable for a variety of applications, such as analog control panel, optical communications equipment, automotive applications, and industrial applications. It can provide electrical isolation between a computer and its peripheral devices, such as a printer, scanner, or other external devices. Additionally, the FOD070LR1 is ideal for motor control equipment, allowing external signals to be sent to the motor without physical connections. The optoisolator is also used to drive relays, and the low power consumption and large temperature range make it suitable for solar power applications.

The FOD070LR1 has several advantages compared to traditional optoisolators, as it provides consistent high level of isolation across a wide range of input frequencies. The phototransistor also provides a higher level of current handling capacity and ensures accurate tracking of the input signals. Additionally, the optoisolator provides long life operation due to its laser-transistor integrated construction. The optoisolator also produces less noise than other optoisolator solutions, leading to higher efficiency and reliability. Moreover, the optoisolator provides a low power consumption and fast response times make it suitable for a wide range of applications.

In conclusion, the FOD070LR1 is a new type of optoisolator that utilizes photovoltaic output technology in order to provide maximum isolation performance in a compact package. It provides a higher level of signal isolation than other optoisolator solutions, and the low power consumption and large temperature range make it suitable for a variety of applications. The optoisolator also provides long life operation due to its laser-transistor integrated construction and consistent high level of isolation across a wide range of input frequencies. Furthermore, the optoisolator produces less noise than other optoisolator solutions, leading to higher efficiency and reliability.
