CNW138300

Optoisolators - Transistor, Photovoltaic Output

CNW138300 is a type of optoisolator, which uses a light-emitting diode and a phototransistor separated by an insulation gap to isolate the input and output circuits. The CNW138300 can be used for signal transmission, power transmission, protection, and optoelectric conversion, in applications such as signal detections, switching circuit relay and power conversion.

Application Field

Optoisolators such as the CNW138300 are ideal for signal transmission and power transmission, particularly in situations where isolation is required and where direct connections cannot be made. The CNW138300 is also suitable for situations in which there is a need for optical signal transmission, such as in communication systems. It is also suitable for use in areas such as industrial equipment, instrumentation, process control, medical equipment, and automotive applications.

Working Principle

The CNW138300 optoisolator consists of a light emitting diode (LED) and a phototransistor, connected by a gap of air. When an electrical signal is applied to the LED, it emits light and the phototransistor detects the light. This causes a current to flow in the phototransistor and an output signal is generated. This output is then relayed to the other circuit, without any electrical connection between the two.

The CNW138300 optoisolator is designed to achieve very high isolation levels, much higher than can be achieved with conventional electrical isolation methods. It has a maximum isolation voltage of 4.5kV and can operate in temperatures of -40°C to +125°C. The CNW138300 is also designed to be highly resistant to vibration and shock.

The efficiency of the CNW138300 optoisolator is very high, which means it is capable of transmitting more power than other types of optoisolators. It can withstand input currents of up to 5A and has a maximum output current of 500mA.

The CNW138300 is a popular optoisolator for a variety of applications. Its ability to provide high isolation and its high efficiency makes it the ideal choice for signal and power transmission in a wide range of applications.
