The 4N35-060E is a Transistor Photovoltaic Output optoisolator, or optocoupler, which is a type of electrical component responsible for providing electrical isolation between two circuits. An optoisolator combines a source of light, typically an infrared LED, with a photosensitive device such as a photodiode, transistor or thyristor. The LED emits light, and the photosensitive device then detects the light energy and creates an electrical signal in the other circuit. Using an optoisolator allows for voltage isolation between two circuits, preventing overvoltage and ground loop problems.

Application Field

The 4N35-060E optoisolator is typically used in industrial process control, motor control, digital logic systems, lighting control, and power conversion applications. It is ideal for systems which need to isolate signals at low power and/or low voltage. It is also suitable for applications with sensitive electronics and/or systems which require a high level of accuracy. Additionally, this optoisolator can be used for analog and digital interfaces that require a fast switching speed and/or high stability.

Working Principle

The 4N35-060E optoisolator operates on the principle of photovoltaic isolation. A photovoltaic cell, or photodiode, acts as a photosensor and is used to detect light. The photodiode is connected to a transistor, which switches on and off at different light intensities. This switching action causes a voltage drop across the transistor, producing a signal in the secondary circuit. This signal can then be used to control other circuitry or devices.

The 4N35-060E optoisolator is designed to detect light at very low power levels, making it ideal for systems that are operating in a low-power environment. It is also optimized to provide very reliable optical performance, ensuring that signals are detected accurately and at the correct intensity. Additionally, the optoisolator is designed to provide excellent insulation between the two circuits and can withstand high levels of transients and/or power surges.

The 4N35-060E optoisolator is a versatile and reliable component that can be used in a variety of applications. Its small size and high performance make it a suitable choice for many projects.
