OCP-PCT124/A

Optoisolators are electronic components that use a light source, typically an infrared LED, to move electrical signals between two isolated electrical circuits. The OC PCT124/A owns to a family of optoisolators recognized as “Transistor, Photovoltaic Output”.As a Transistor, Photovoltaic Output optoisolator, the OC PCT124/A provides an electrical isolation barrier between the input LED light source and output transistor. It works by using the LED transmissivity to create an internal current just at the transistor’s base, when an external voltage is applied to the device. This internal current is used as the triggering signal for the output device, activating it and allowing an electrical connection between the two isolated circuits. The OC PCT124/A optoisolator is available in a number of package options and comes with several advantages over other optoisolators, including low cost, low power consumption, and high isolation voltage. Due to its low cost, the OC PCT124/A is becoming increasingly popular in a variety of electronic applications. ApplicationsThe OC PCT124/A optoisolator is used in a wide range of industrial and consumer applications. It is commonly used for digital logic control in industrial equipment, such as testing and measurement equipment or motor controls. It is also used for space-saving, low-cost circuit protection and isolation in I/O structures. In consumer applications, the OC PCT124/A is used in video game controllers, remote mouse systems, remote-control toys, and robotics. It is also widely used in automotive applications for controlling electronic accessories such as door locks, alarm systems, signals, and lights. Working principleAt the heart of the OC PCT124/A optical isolator is the light-sensitive photodiode which produces a photocurrent when exposed to light. The photocurrent is then amplified by a high-gain amplifier and applied to the base of an output transistor, activating it and forming an electrical path between the two isolated circuits. When a voltage is applied to the diode, the LED inside the optoisolator will emit light in a narrow spectral range. This light is then focused onto the photodiode which produces a photocurrent proportional to the light intensity. The amplitude of this photocurrent is then amplified and applied to the base of the output transistor, activating it and allowing an electrical path to be formed between the two isolated circuits. The key benefit of the OC PCT124/A device is its high isolation voltage, allowing the device to be used in high-voltage applications. It is also designed with an integrated transient voltage suppressor (TVS) which provides protection from electrostatic discharge (ESD), further increasing its protective capabilities.In conclusion, the OC PCT124/A optoisolator is an affordable and reliable device that provides electrical isolation between two isolated electrical circuits. It is widely used in industrial and consumer applications, as well as in automotive applications, thanks to its low cost, low power consumption, and high isolation voltage.
