Optoisolators - Transistor, Photovoltaic Output, can be employed in a wide range of applications, including, but not limited to, data transmission and instrumentation. CNY117-3, one of the most popular optoisolators in this category, is widely used for a variety of purposes. As a high-performance and reliable optoisolator, CNY117-3 can effectively isolate circuits, offer voltage-stabilization, and provide extremely accurate data conversion and signal processing. In this article we will discuss the application field and working principle of CNY117-3 optoisolator.

CNY117-3 Application Field

CNY117-3 is notably applicable for digital data conversion and transmission between different circuits of varying voltages. In such an application, data can be converted between circuits through a numerical proportion. This requires the premise of a different voltage hierarchy between the two sections of the circuit. The current differential between the two circuits can be amplified or suppressed by controlling the base current of the output transistor.

In addition to its data conversion and transmission capability, CNY117-3 also provides excellent voltage-stabilization, and provides ultra-low power consumption. Furthermore, CNY117-3 can be used in AC/DC signal conditioning, frequency synthesizers, PLL circuits, and other circuits requiring high accuracy and excellent isolation capabilities.

CNY117-3 Working Principle

CNY117-3 optoisolator mainly consists of an infrared emitting diode and an infrared phototransistor. When the input signal is applied, the power diode converts it into an optical signal that passes through the phototransistor. The phototransistor then converts the optical signal into an electrical signal that is applied to the output terminal. Because the two circuits are isolated from each other by a light barrier, the CNY117-3 optoisolator offers excellent data transmission and circuit isolation capabilities.

The working principle of the CNY117-3 optoisolator is based on the electrical conduction of the detachable diode. The current is applied through the diode, which then supplies power to the Silicon NPN transistor. The base current of the transistor is then modulated according to the input signal, which can be used to modulate the current output of the transistor. The modulation of the base current can then be used to amplify or suppress the current differential between the two circuits, which is what makes CNY117-3 so useful for data conversion and transmission purposes.
