Optoisolators are an important type of electrical isolation method which uses an optical link for transmitting digital signals between two separated circuits. As the name suggests, the isolation effect is accomplished through a photo or lightbeam. The isolation also prevents electrical noise from one circuit interfering with another. There are various types of optoisolators, such as transistor, photovoltaic output, which this article will focus on. This article looks at the CNW11AV3S application field and working principle.
CNW11AV3S Applications
The CNW11AV3S optoisolator, developed by Vishay, is a 4-pin device in a 4-pin SOT-23 package. It provides a low cost, low power isolation solution with a transfer current ratio of 1/50. This device is suitable in industrial control systems, alarm systems, personal computers and white goods.
The CNW11AV3S is also suitable for digital output signals in systems that require signal transmission from a low current to a higher current circuit. Another application of CNW11AV3S is to protect low power ICs from high voltage spikes or other transients generated in the same circuit. In addition, this optoisolator is used for controlling sensor devices like encoders, timers, counters, switches, valve actuators, etc. Thus, it is widely used for industrial automation and control applications.
CNW11AV3S Working Principle
The CNW11AV3S optoisolator contains an LED and a collector-base coupled phototransistor, both of which are mechanically sealed inside the same housing. When the LED of this device is energized, it produces light, which is absorbed by the phototransistor. This causes current to flow through the phototransistor, activating it. The activated phototransistor then acts as a switch, controlling the output current of the optoisolator.
In this way, the CNW11AV3S optoisolator can control the flow of current from the input to the output circuits without any direct electrical connection between them. This provides much higher levels of isolation, which ensures that the output signal will not be distorted by noise from the other circuit. Moreover, this optoisolator has a low off-state leakage current and a low diode saturation voltage.
The CNW11AV3S optoisolator is an ideal choice for applications where electrical isolation is critical. It provides a low-cost, low-power isolation solution with a high level of isolation performance. Furthermore, it can be used to control or switch low-power ICs from high-voltage transients, as well as to control various types of sensors in industrial automation applications.
