Optoisolators, sometimes called optronic isolators, are devices that are used to provide electrical isolation between two separate circuits. They have been used for a variety of applications, such as providing power to microprocessors, isolating analog and digital audio signals, and protecting against electrical surges or voltage transients. The PS9851-2-F3-AX optoisolator is part of the Logic Output family, offering an ideal isolation solution for low-power applications where input power is limited. This article will explain the application field and working principle of the PS9851-2-F3-AX optoisolator.

The PS9851-2-F3-AX optoisolator is suitable for use in a range of low-power applications. Its ability to provide noise-free, low-power electrical isolation serves several useful functions, such as protecting sensitive devices from power surges, isolating circuits to prevent crosstalk or interference, and providing a safe connection point between circuits. The PS9851-2-F3-AX optoisolator can be used in a variety of applications, such as low-power audio signal operations, powering small motors, and controlling light sources.

The PS9851-2-F3-AX optoisolator functions on the principle of optoelectronics. It consists of two parts: an LED (light-emitting diode) and a phototransistor. The LED is used to generate a beam of light, which is then detected by the phototransistor. The phototransistor then amplifies the signal and delivers it to the output, creating electrical isolation between the input and output circuits. The amount of current delivered to the output depends on the amount of light detected by the phototransistor, so the level of electrical isolation depends on how much light is being generated by the LED.

The PS9851-2-F3-AX optoisolator is designed to offer superior performance in low-power applications. It offers a high-stability current transfer ratio, ensuring reliable isolation between the input and output signals, and has a minimum input/output response time of 7µs. It has an input and output voltage range of 0-5V, and its operating temperature range is from -40°C to +85°C. The unit is ESD (electrostatic discharge) protected to prevent damage from static electricity.

The PS9851-2-F3-AX optoisolator can be used as a replacement for traditional mechanical relays or solid-state relays in a variety of low-power applications. Its low-power operation and fast response time make it an ideal isolation solution for these applications. In addition, its wide operating temperature range and ESD protection ensure reliable operation even in harsh environments. The PS9851-2-F3-AX optoisolator is a versatile solution that offers reliable electrical isolation between input and output circuits in low-power applications.
