Optoisolators - Transistor, Photovoltaic Output

IL300-EF Application Field and Working Principle

Optoisolators are devices that offer electrical isolation between input and output circuits with the help of an optical link. Among the different optoisolator types, the most common is the one with transistor output. The IL300-EF is a photovoltaic optoisolator that uses an LED (light emitting diode) to transmit the input signal to a phototransistor to provide isolation between circuits. The IL300-EF optoisolator has a maximum on-state voltage of 50V and offers a wide range of applications such as switching, barrier protection, power and load driving.

The working of IL300-EF optoisolator is based on the following principle. The input side of optoisolator consists of a LED that offers input signal across the anode and cathode. The LED then emits light that is projected across an internal incandescent barrier to the phototransistor. When the LED is ON, the phototransistor is exposed to the light. This in turn activates the phototransistor that is connected to the output terminal. The output terminal then obtains the required voltage or current depending upon the input signal.

The IL300-EF optoisolator is available in an industry standard three leaded package. It has a rated power dissipation of 300mW and can be used in industrial and medical applications to provide opto-coupled isolation assistance. It also meets international safety standards as specified by the IEC standards. The phototransistor portion is bidirectional, meaning that it couples the LED light in both directions. The typical collector-emitter you’ll find on other optoisolators.

The IL300-EF has a wide range of applications and is suitable for a variety of industries. It is used for data transfer processes in industrial applications as well as in machinery to prevent contamination of circuit or component failure. It also finds applications in medical equipment as it is able to electrically isolate components. It is also used to isolate any power or signals that need to be electrically isolated.

In summary, the IL300-EF is a photocoupler that is suitable for bidirectional data transmission. It offers excellent isolation performance and has been designed to meet international safety standards. It is widely used in data transfer process and other industries to provide electrical isolation between circuits.
