CNW84S

The CNW84S optoisolator is an optocoupler that isolates the control circuit from the driving circuit, and is a semiconductor device with transistor and photoconductive output. It is commonly used in automated process control, telecom, instrumentation, motor control, and other applications that require a high level of insulation between two circuits. With its high speed, high reliability, and acceptability in noisy environments, the CNW84S is an excellent optoisolator choice.

The CNW84S optoisolator consists of two parts, the LED and the transistor. The LED is the optical emitter, and the transistor is the detector. The LED emits a band of visible light, which is then converted into a photocurrent, triggering the transistor. The transistor utilizes this current to drive a voltage to the output circuit.

The CNW84S optoisolator offers excellent electrical characteristics. Its high-speed response time of 1µs ensures the proper operation in fast-moving applications. It also provides an isolation voltage of 500V, allowing for safe operations in noisy electrical environments. In addition, it provides power dissipation of up to 0.7W, allowing it to easily meet the needs of high-powered applications.

In terms of working principle, the CNW84S optoisolator is designed to prevent energy from the control circuit from entering the driving circuit. This is accomplished by means of a LED and a transistor. The LED emits a band of visible light, which is then converted into a photocurrent. This photocurrent is then used to drive the transistor, triggering a voltage to the output circuit. The output circuit is thus prevented from being affected by energy from the control circuit.

The CNW84S optoisolator is designed to provide high noise immunity and reliable operation in various electrical applications. It also features high speed, high isolation voltage, and power dissipation suitable for high power applications. Its excellent electrical characteristics make it an excellent choice for automated process control, telecom, instrumentation, motor control, and other applications that require isolated circuits.
