Optoisolators - Transistor, Photovoltaic Output

Optoisolators are electronic components designed to pass signals from a certain source to another without having physical contact between the two. This could be essential in multiple scenarios in order to prevent damage caused by electric shock, protect from high voltages, and reduce noise, just to list a few.Specifically speaking, the 6N135-000E optoisolator is an integrated circuit consisting of a phototransistor and a photovoltaic cell. It is a very versatile optoisolator, commonly used to drive electronic and electrical circuits due to its high input-output isolation and high-current operation.Let’s now discuss the application fields and working principle of the 6N135-000E optoisolator.

Application Field

Various applications are found for the 6N135-000E optoisolator. Such designs are commonly used as outputs to drive relays, motors, and solenoids, as well as programmable logic controllers (PLCs).Optoisolator designs like the 6N135-000E are also used in push-button switches, in order to provide direct driving of optocoupler LED outputs and power transistors without having to use additional buffering stages and components.The 6N135-000E optoisolator is usually wired to a current or voltage source, for which the voltage regulation and current limit features make it a great choice for such applications.

Working Principle

The 6N135-000E optoisolator works analogous to an electric switch (SPST) and goes against the traditional bipolar transistor. Its operation is based on two essential components: a phototransistor and a photovoltaic cell.The phototransistor works in the same fashion as a regular transistor: by applying a voltage to its base it can be switched on and off. The photovoltaic cell (photodiode) is used to activate the phototransistor and it is powered by a light source.When the light source is blocked, the phototransistor is cut off and the output is turned off. However, when the photodiode is exposed to light, the phototransistor is switched on, and the output will be energized. This is the crux of the 6N135-000E optoisolator’s operation.This optoisolator has a DC isolation voltage rating between input and output of >2.5kVdc, with a working voltage of 4.5Vdc. Its collector-emitter voltages vary from 25Vdc with a current of 25mA (at which the device is considered an open circuit), upwards to 50Vdc with a current of 50mA.

Conclusion

The 6N135-000E optoisolator is an integrated circuit consisting of a phototransistor and a photovoltaic cell, and is commonly used to drive electronic and electrical circuits due to its high input-output isolation and high-current operation. Its applications include driving relays, motors, and solenoids, as well as in push-button switches, providing direct driving of optocoupler LED outputs and power transistors. The working principle of the 6N135-000E optoisolator is based on two essential components: a phototransistor and a photovoltaic cell. When exposed to light, the phototransistor is switched on, and the output will be energized; when the light source is blocked, it is turned off.
