Optoisolators, also known as optocouplers or photocouplers, are a type of electronic component that allows a light-emitting diode (LED) to be coupled with a photovoltaic cell for electrical isolation. The CNX38UW is a part of this type of optoisolator family, capable of providing electrical isolation between different circuits using light to transmit the signals. This article will provide a detailed overview of the CNX38UW application field and working principle.

The CNX38UW is an optoisolator with transistor output. It is suitable for applications that require a maximum transistor collector-emitter voltage of 30V. This voltage can be further increased up to 60V if the LED current is reduced. The CNX38UW also features a high input current transfer ratio of 750%. Additionally, it has a high input switching speed of 0.1s and a high off-state output voltage of 200V.

The CNX38UW can be used in a wide range of applications, such as electrical power protection, instrumentation, medical applications, military, safety systems, traction control systems, and automotive applications. In most cases, this optocoupler can be used as an electrical isolation barrier that prevents high-voltage hazards from occurring.

For example, the CNX38UW can be used to protect equipment from power surges, spikes, noise, and other disturbances. Additionally, it can be used to isolate relays, transistors, and other devices from high voltage or humidity. It can also be used in motor control circuits to protect the motor from excessive voltage.

The working principle of CNX38UW is based on the principle of light transmission. It consists of an LED and a photovoltaic cell which are electrically separated from each other. When the LED is triggered with an external signal, it emits light which is absorbed by the photovoltaic cell. As a result, the photovoltaic cell generates an output voltage which is then used to control the transistor.

The CNX38UW has three terminals – the anode, the cathode, and the output signal. The anode and cathode terminals are connected to the LED and the photovoltaic cell respectively. The output signal is connected to the transistor. When an external signal is applied to the anode of the LED, it emits light which is then absorbed by the photovoltaic cell. The photovoltaic cell then generates an output voltage which is used to control the transistor. This causes the transistor to either switch on or off.

To sum up, the CNX38UW is a type of optoisolator with transistor output and is suitable for a variety of applications such as power protection, instrumentation, motor control, and automotive. The working principle of the optoisolator is based on the principle of light transmission. It consists of an LED and a photovoltaic cell which are electrically separated from each other. When an external signal is applied to the LED, it emits light which is then absorbed by the photovoltaic cell.
