Optoisolators - Transistor, Photovoltaic Output

Optoisolators are a form of optical isolation, which uses light to isolate electrical circuits and separate two signals. K817P2 optoisolators are designed with an LED emitter and a photovoltaic transistor output. This combination offers the required flexibility, noise immunity and isolation for a variety of applications.

Application

K817P2 optoisolators are designed for use in a range of applications including industrial, motor control, and consumer products. The product is designed for applications requiring high-power logic-level signal isolation, such as powering motor drives and similar circuits. It can also be used in systems operating at high voltages and/or frequencies, such as DC-DC converters, AC motor drives, and switching regulators.

The K817P2 optoisolator is also suitable for a range of other applications such as power switching, lighting control, HVAC, audio signal processing, and data and control isolation. Its robust package design enables operation in high-temperature environments, including over-temperature monitoring and shutdown protection.

Relative Advantage

K817P2 optoisolators have several significant advantages over other optoisolators. First, its photovoltaic output offers superior signal isolation, which prevents ground loop and transversal interference. Second, the low voltage rating of the device makes it suitable for use in consumer and industrial products. Third, the high isolation voltage rating enables operation at high frequencies. Fourth, the low current rating makes the device suitable for use in devices with low power consumption. Finally, the wide operating temperature range allows the device to operate in extremely hot or cold environments.

Working Principle

The K817P2 optoisolator consists of an LED emitter and a photovoltaic transistor output. When the LED is energized, it emits light which is then converted to a voltage level by the photovoltaic transistor output. This voltage level is then used to control the circuit, providing signal isolation, ground loop elimination, and transversal interference prevention.

The optoisolator can be used in a number of different applications, depending on the requirements of the circuit. In motor control applications, for example, the optoisolator can be used to provide digital control over the speed of the motor. Similarly, in industrial applications, the optoisolator can be used to provide isolation for a system’s high voltage or high frequency signals.

The K817P2 optoisolator is a highly reliable and rugged device, making it ideal for a range of industrial applications. Its low voltage, current, and isolation ratings make it suitable for use in many consumer and industrial applications. Moreover, the optoisolator’s wide operating temperature range allows it to operate in extremely hot or cold environments.
