Optical isolation is the practice of fundamentally isolating electrical circuits by using light-transmitting media, such as fiber optic cables, for direct current voltage signals. The 4N36 optoisolator is one type of apparatus used to achieve this isolation. This article will discuss the application fields of the 4N36 optoisolator and explain the working principle behind it.

The 4N36 optoisolator is the most commonly used and widely accepted optoisolator as it is reliable and cost effective. This type of optoisolator features a transistor output, and can be used in a variety of applications. The most common application for the 4N36 is in the transmission of small signals, where it can be used as a transmitter-receiver system. It can also be used to protect sensitive circuits, achieve a digital input condition, or as part of a power switch.

The 4N36 optoisolator works in the following way: light leakage through the device’s photovoltaic junction will generate a current that is converted to a voltage. This voltage is then transferred to the internal transistor of the optoisolator, causing it to turn on and close the output line. This action serves to isolate the input and output of the circuit, allowing for significantly less interference from other signals and devices.

The optoisolator is also capable of protecting sensitive circuits from overloads, over currents, and reversed voltages. This protection is achieved by the internal circuitry of the optoisolator, which will shut off the device’s output in the event of such an occurrence. This makes the 4N36 a common go-to device for power supply and lighting applications, where sources of external interference must be controlled.

The 4N36 optoisolator is designed to operate with a wide range of input currents, allowing for simple short-range calculations for designing circuits. The device’s photovoltaic junction is also capable of operating over a wide range of temperatures, allowing for reliable and long-lasting operation. Finally, the device is designed to be immune from electrical noise and resistant to ESD (electrostatic discharge), making it a reliable and safe choice in the applications mentioned above.

In conclusion, the 4N36 optoisolator has a wide variety of application fields and provides excellent protection against interference and overloads. Its working principle is based on the photovoltaic junction, which enables reliable operation over a wide range of temperatures. As such, it is one of the most commonly used optoisolators and can be found in many application fields, from power supply to lighting.
