The 6N136M-V optoisolator is an advanced isolator that combines a transistor and a photovoltaic output in one device. Its application field and working principle can be split into several parts.

Optoisolator Application Fields

• Logic isolator - used to isolate logic signals from each other, to protect the logic circuitry.
• Signal isolator - used to isolate analog signals, such as voltage and current signals.
• Power isolator - used to isolate HV (High Voltage) electrical loads from the main control power circuit.

Transistor Inside the Optoisolator

Inside the optoisolator, the transistor is used to act as a switch between the input signal and output, allowing the optoisolator to provide electrical isolation. The transistor can be of the PNP or NPN type, depending on the design of the optoisolator. It is used to control the flow of current, and works by using electronic base current to control the output current.

Photovoltaic Output

The photovoltaic output of the optoisolator is the result of light energy being converted into electrical energy. When the light beam hits the photodiode inside the optoisolator, the electric field of the photo-diode generates a voltage that is proportional to the light intensity. This generated voltage is then used to power the optoisolator.

Working Principle

The optoisolator works by using the transistor to act as a switch between the input signal and output. The input signal is sent to the transistor, which switches it on or off based on the current passing through it. When the transistor is activated, the voltage generated by the photovoltaic output is used to control the output signal. This output signal can then be used for logic control, signal transfer, or other applications.

The 6N136M-V optoisolator combines the advantages of transistor and photovoltaic output in one device. This makes it an ideal choice for applications such as logic isolators, signal isolators, and power isolators. Its compact size also makes it convenient to install and use.
