Optoisolators, sometimes referred to as optocouplers, are devices that use light for the purpose of isolation of an electronic signal, often from a high voltage signal, from an otherwise electrically noisy environment. The TLP183(GRL,E is part of a family of optoisolators and specific to transistor, photovoltaic output applications. In this article, the properties and working principle of the TLP183(GRL,E are discussed and explained.

Features of the TLP183(GRL,E

The TLP183(GRL,E is a general-purpose trans-photovoltaic optocoupler, and popular for its wide range of applications. It has several features, which help it to be a reliable optocoupler:

• Isolation voltage rating of up to 7.0kV.
• High input-output current transfer ratio up to 100mA.
• Operating temperature ranges between -55°C and 105°C.
• Wide range of input-output voltage combinations.

Circuit Construction

The working principle of the TLP183(GRL,E is based on its construction. The optocoupler consists of two main components, the emitter and the photodiode. The emitter consists of an LED and an NPN transistor mounted on a single package. The photodiode is a photovoltaic component, which changes the optical energy into electrical energy.

The LED in the optoisolator emits light when its electrode is energized. This light is then captured by the photodiode and is converted into electrical energy. This electrical energy is passed to the NPN transistor which amplifies the current and sends it to an output.

Applications

The TLP183(GRL,E can be used in many different applications. It can be used as isolation amplifiers to prevent the electrical noise of external sources from affecting the signal. It can be used as a voltage or even current regulator, to control the output voltage to the required level. It can also be used in safety circuits to monitor the position of switches, safety relays, and other high voltage components. As the device is basically a DC-DC converter, it can be used to supply power to extra circuits.

Advantages and Drawbacks

The major advantage of optoisolators is their capability of electrical isolation, they can provide electrical insulation between different circuits, even if they are not far apart. This major advantage of the optoisolator reduces the risk of conducting electric shock and sparks. Major drawback of optoisolators is limited current transfer ratio. The higher the current transfer ratio, the more efficient the optoisolator is.

Conclusion

The TLP183(GRL,E optoisolator is a popular way of providing electrical isolation from an electrically noisy environment. It consists of an LED and a photodiode, with an NPN transistor to amplify the current. The features of the optoisolator such as its high input-output current transfer ratio, and wide range of input-output voltage combinations, make it ideal for use in a wide range of applications, such as isolation amplifiers, voltage and current regulators, and safety circuits.
