Optoisolators (optical couplers, opto-couplers, opto isolators or photocouplers) are devices used to electrically isolate two or more circuits with one physical connection. There are different types of optoisolators based on the output type, which can be either a transistor, a thyristor, a fan-out device, a diode, a photovoltaic device or an integrated circuit. Among these, ANPV1121SX belongs to the photovoltaic output type and is designed specifically for use in industrial applications. Let’s find out more about the application field and working principle of this device.

ANPV1121SX is a low-cost optoisolator with high efficiency and fast switching speed. It can be used in alternating voltage circuit with rated current up to 100mA, and is suitable for AC/DC supply voltage between 30V AC/DC and 300V AC/DC. It has high insulation voltage of 2500Vrms and low saturation voltage of 0.2V. It is also capable of withstanding surge voltages of up to 6kV. The device is RoHS compliant and is available in tube packaging with a pin spacing of 8mm.

This optoisolator works on the principle of photoelectric conversion. It has an input part, an output part and an intermediate isolator part. The input part has an LED embedded inside it, which produces a light when current is supplied to it. This light is detected by the optical isolator, such as silicon or light resistant resistor, which activates the output part. In the output part there is a transistor or a photovoltaic device which is responsible for switching signals. The output part may take the form of a transistor that switches on and off, a thyristor that can block and open high current or voltage circuits or photovoltaic cells that generate current when light is detected.

The ANPV1121SX is suitable for use in lighting, temperature controlling applications, embedded power supply circuitry and other industrial applications. Its working frequency is up to 2KHz and can be used with a wide range of active and passive components. It has low power consumption and provides excellent isolation protection against power supply and noise. The device features a wide range of response times ensuring accurate and reliable source switching.

ANPV1121SX is a reliable, high speed and cost-effective optocoupler for use in industrial applications. It is easy to use and is ideal for applications that require signal transfer between circuits with low voltage and high isolation requirements. The device is designed to provide a high degree of reliability and is compliant with different international safety standards making it suitable for a variety of industrial applications. It provides excellent signal integrity, low power consumption and fast response time making it a great choice for industrial applications.
