Optoisolators protect electronic systems against ground loops and noise, allowing high voltage AC and DC signals to control low voltage outputs. This provides isolation between input and output circuitry with no direct electrical connection. One Optoisolator that gives this type of protection is the EL817S(D)(TA)-V.

The EL817S(D)(TA)-V is a compact, 4-pin, single channel, ultra-fast, and advanced optoisolator with transistor and photovoltaic output. It can detect AC or DC input signals from small to moderate power range with high efficiency. With its compact design, the EL817S(D)(TA)-V is an ideal solution for applications such as motor control, power measurement, digital communication links and data acquisition systems.

The EL817S(D)(TA)-V has a photo-coupled transistor photovoltaic output. The photo-coupled transistor is a commonly used output component and is used in many devices. This type of output is optimal for applications that require high speed with minimal noise. It has a fast switching speed and a low current transfer ratio to ensure high accuracy in data transmission. The photovoltaic output has a fast time delay of 0.9µs and a fast photovoltaic response time of 0.2µs.

The EL817S(D)(TA)-V consists of an internal bias voltage which determines the working voltage of the opto-isolator. This bias voltage is usually in the range of 6V-24V with a maximum voltage rating of 28V. The opto-coupler is equipped with an overload protection circuit which prevents the opto-coupler from operating in overload conditions. It also has an integrated temperature compensation system that ensures the circuit can work in the most extreme temperatures. The opto-isolator has a power dissipation of 0.3W, a maximum safe operating temperature of 85°C and an operating humidity range of 0 to 95%. This device is available in standard 4-pin single in-line package.

The EL817S(D)(TA)-V utilizes the principle of photo-induced electric charging. This principle utilizes the interaction between light and the properties of a semiconductor to transfer a signal. A light sensitive device, such as an LED, is used to generate light when an electric signal is received. This light is then absorbed by a light sensitive diode, such as a phototransistor or a photodiode. This light absorption then triggers a change in voltage across the diode, and the photovoltaic effect occurs. This voltage change is then amplified and transferred to the output of the opto-isolator.

The EL817S(D)(TA)-V is suitable for numerous applications, such as power trouble-shooting device, electric switch, switch mode power supply, sensing circuit, etc. With its high isolation voltage rating, fast response times and low power dissipation, the EL817S(D)(TA)-V is a cost effective solution for providing high isolation for various applications.
