Optoisolators, which are sometimes called opto-isolator, optocoupler, photocoupler, photoelectric isolation method, photocoupler, optical coupler, or optically isolated input device, and are used in a variety of applications. The CNW135300 is an optoisolator designed for transistors with a photovoltaic output. In this article we will discuss the application field and working principle of the CNW135300.

The main application of the CNW135300 is in devices that need electrical isolation, such as motor control circuits or line isolation systems. It provides galvanic isolation between input and output, allowing the circuit to be connected and operated without any risk of short-circuiting or other hazardous conditions. The device also helps to reduce electromagnetic interference (EMI) emissions, which is an important consideration for any system where connection to highly sensitive electronic equipment may be required. The CNW135300 is also suitable for use in applications such as sensors and controllers, where isolation of an input signal is required.

The CNW135300 is a transistor optoisolator with a photovoltaic output. The device consists of an LED (light emitting diode), which emits optical energy in response to electrical energy, and a photovoltaic cell which converts the optical energy into an electrical signal. When the LED is turned on, the photovoltaic cell will generate a small signal, which is then amplified using a transistor. This amplified signal can then be used to drive external components, such as a relay or a motor. The advantage of using the CNW135300 in this application is that it provides electrical isolation between the input and output signals, which means that the system can be connected and operated without the risk of short-circuiting.

In addition to providing electrical isolation, the CNW135300 also provides advantages such as low power consumption, fast response time, and high reliability. The device can operate from a wide range of supply voltages, from 5V to 15V, and is available in a range of package styles including PDIP, SMD, and TO-220F. For high-temperature applications, the CNW135300 also features a temperature range of -40 to +85C.

The working principle of the CNW135300 is relatively straightforward. When the LED is turned on, photons are emitted from the LED’s active surface, and these photons are absorbed by the photovoltaic cell. The absorption of the photons causes a voltage to be generated in the photovoltaic cell, which is then amplified by the transistor. The amplified voltage is then used to drive external components, such as relays or motors. The electrical isolation provided by the CNW135300 ensures that the input and output signals remain separate, allowing the circuit to be connected and operated without any risk of short-circuiting or other hazardous conditions.

In conclusion, the CNW135300 is a versatile optoisolator designed for transistors with a photovoltaic output. It provides electrical isolation between the input and output signals, making it ideal for applications such as motor control circuits and line isolation systems. The device also features low power consumption, fast response time, and a wide temperature range, making it suitable for use in a variety of applications. The working principle of the CNW135300 is relatively simple, and involves the conversion of optical energy into electrical energy via a photovoltaic cell.
