Optoisolators are electrical components that enable electrical isolation between two circuits. They make it possible to transmit information between circuits while maintaining electrical insulation between them. The 6N135-300E is a type of optoisolator, specifically a transistor photovoltaic output, from the Sharp Corporation. This optoisolator has the ability to offer a high-level output current and fast switching speeds, making it suitable for application in a range of markets. In this article, we\'ll explore the application field and working principle of the 6N135-300E.

Application Field

The 6N135-300E belongs to Sharp\'s 6N135/2/3 family of transistor photovoltaic output optoisolators. These components feature a photocoupler, featuring a gallium arsenide infrared-emitting diode and an integrated photo transistor (PT) detector. The 6N135-300E has an adjustable collector-emitter voltage rating that ranges from 5 to 35 V and a maximum output of 100 mA. Furthermore, the 6N135-300E has fast switching speeds of up to capabilities of 300 ns, which makes it suitable for response to fast signal frequencies.

Due to its adjustable voltage rating and fast switching speeds, the 6N135-300E is suitable for use in applications requiring electrical isolation and fast response times. One example of this is its use in computer keyboards. Because the USB connection needs to be electrically isolated from the keyboard, an optoisolator is used to enable data transmission while keeping the USB port safe from any potential undesired electrical current.

The 6N135-300E is also suitable for use in applications that require optically isolated low power signals. This includes telecommunications equipment using optical fibers for data transfer, as well as a range of industrial control systems. These type of applications are highly demanding because the optoisolator needs to be able to switch the signal from the input device to the optical output device at very fast speeds.

Working Principle

The working principle of the 6N135-300E is very simple. The optoisolator consists of two electrodes separated by an insulating material, usually silicon dioxide. When an electrical signal is applied to one of the electrodes, it excites an electron in the other electrode, which in turn emits a photon of light. This light is then detected by the photodiode, which raises the output voltage, allowing the signal to be sent to a different circuit.

Once the signal is transmitted to the other circuit, the voltage on the output side is brought down, allowing the circuit to be isolated from the other one. The 6N135-300E operates at very high speeds because it has a transit time of just 6 ns. This makes it suitable for applications that require fast response times.

The 6N135-300E optoisolator can be used to enhance the reliability of many types of systems. Its adjustable voltage rating, high output current, and fast switching speeds make it suitable for use in a variety of applications. The optoisolator is used to provide electrical isolation between two circuits while ensuring data transmission between them.
