EL817(D)-G

Optoisolators are an important category of electronic components, especially for applications with high power or hazardous environment. The EL817(D)-G optoisolator is one such component, and is commonly used for applications such as equipment switching, motor control, and automatic switching.

The EL817(D)-G optoisolator is a transistor, photovoltaic output device, which provides electrical isolation between input and output circuits, and allows high input voltage signals to be optically coupled to low power outputs. It contains a photocoupler inside its protective package, and the package is available in either surface mount or through-hole designs. The device consists of an infrared emitting diode optically coupled to a phototransistor.

When an input signal is applied to the input pin of the optoisolator, the emitting diode is switched on. This causes the LED to emit infrared light which is detected by the phototransistor, which in turn switches on its output transistor. This in turn drives the output voltage of the optoisolator, making it ideal for many low power applications. The absence of a direct electrical connection between the input and output provides the necessary isolation for the device to function, and makes it suitable for applications which otherwise would require a large amount of energy or hazardous conditions.

In addition, the EL817(D)-G optoisolator is capable of operating in high temperature (up to 125°C) and is load current immune, meaning that even with light load current applied, the optoisolator will still operate without affecting performance. The device is highly reliable, long-lasting, and has a high withstand voltage rating, making it applicable for many different industrial applications.

The EL817(D)-G optoisolator offers a range of applications in the industrial sector. It is suitable for motor control systems, on-off or PWM switching in a variety of environments, lighting control, air conditioning systems, humidity control systems, etc. Due to its high temperature and load current immunity, it can also serve as a low power driver for general-purpose thyristor loads.

The EL817(D)-G optoisolator is a versatile component, and provides an excellent combination of performance and cost for many applications in the industrial sector. Its features such as insulation, high temperature tolerance, and immunity to light load currents make it ideal for use in many environments.
