Optoisolators - Transistor, Photovoltaic Output

The EL817(S)(A)(TD)-VG is a type of optoisolator, specifically a 6-pin phototransistor output device, designed to transfer electric signals through an optical barrier to isolate grounds and operate in high noise environments.

An optoisolator is a type of output device used to send and receive signals using light rather than electrical connections. It takes the form of a small, low-power device that can be easily and inexpensively integrated into a variety of electronic circuits. The EL817(S)(A)(TD)-VG is one such device, offering high performance by transferring electrical signals through an optical barrier to provide electrical isolation. This makes it ideal for applications where high electrical noise, such as generated by large industrial motors, is present, as well as for high voltage, low current applications.

The working principle of the EL817(S)(A)(TD)-VG is based on the use of a light-sensitive phototransistor output. A light source (LED) is connected to the input of the device, which is typically the case for optoisolators. The LED emits light which is detected by the output phototransistor, typically a bi-polar transistor. The output signal is proportional to the amount of light detected, allowing the EL817(S)(A)(TD)-VG to act as an analog-to-digital converter, taking an analog signal and converting it to a digital signal.

Apart from the high noise and high voltage applications, the EL817(S)(A)(TD)-VG offers many other features, making it suitable for a wide range of applications. It has low power consumption and its small form factor makes it suitable to be integrated into various types of circuits. The device is RoHS compliant and conforms to UL flammability standards. It is also available in many industry standard packages.

The EL817(S)(A)(TD)-VG is commonly used in control circuits, alarm systems, industrial automation, and medical systems. It can also be found in automotive applications such as airbag control systems, powertrain control systems, and climate control systems. Additionally, the EL817(S)(A)(TD)-VG can be used for signal and data transfer in computer networks and communication systems.

The EL817(S)(A)(TD)-VG optoisolator provides cost-effective, reliable and fast signal isolation and transfer in a variety of electronic applications. Its small form factor, low power consumption, and robust construction make it an ideal output device for those applications in which precision and accuracy is paramount.
