Optoisolators - Transistor, Photovoltaic OutputOptoisolators are electronic devices that provide galvanic isolation between devices and circuits in electronics. They function as an isolator between two parts of an electronic system, to help prevent interference and maintain noise immunity. Commonly used in motor control, medical devices, avionics, telecommunications and automotive applications, these devices use a light-emitting diode (LED) to drive an optically isolated signal, creating an electrical barrier between the two portions of the circuit. The OPTOL4N35-300E is a specific optoisolator that offers a low-to-medium speed, open-collector transistor, photovoltaic output with its own LED optically isolated from a transistor.The OPTOL4N35-300E offers superior performance for galvanic isolation. With its 1000V Maximum Dielectric Strength at sea level, the device offers sufficient isolation levels to protect both circuits from electrical interference, as well as protect equipment operators against any form of contact with reliable signals. This maximum dielectric strength also ensures long-term reliability and device longevity with minimal risk of electric shock. It furthermore provides both cost effectiveness and low delay times with its fast response times. Moreover, it features a low-energy consumption with its 0.8V LED drop, and offers improved reliability against electrostatic discharge due to its double insulation structure. The device includes an 8-pin DIP package, suitable for a broad variety of applications.The OPTOL4N35-300E functions through the use of a photovoltaic transistor. When the LED is driven, an optically isolated signal is produced, creating an electrical barrier between the two halves of the device. A photovoltaic transistor utilizes the photo-energy created to open and close a circuit. This is done by converting light photons into electrical current. This photo-energy flows from the LED to the photovoltaic transistor, which is coupled to a base-emitter junction, and the transistor remains in an on or off state depending on the energy received from the LED.The OPTOL4N35-300E optoisolator is particularly applicable in fields such as switchgear, motor control, and medical devices. It is often used in switchgear applications due to its ability to maintain and protect circuits from over-voltage, as well as provide insulation against noise, interference, and surges. The device is also often found in motor control applications, due to its fast response times and superior protection against over-current, as well as its support for both DC and AC signals. In the medical field, this optoisolator functions as a critical interface between a patient’s medical device and the rest of the patient’s healthcare and monitoring system. Its low-power consumption, fast response times, double-insulation, and superiordielectric strength help ensure patient\'s safety and comfort.In summary, the OPTOL4N35-300E is a low-to-medium speed, open-collector transistor, photovoltaic output optoisolator with its own LED optically coupled to a transistor. This optoisolator offers a 1000V maximum dielectric strength, fast response times, low-power consumption, double insulation for improved reliability against electrostatic discharge, and an 8-pin DIP package which makes it suitable for a wide array of applications. It is most typically found in switchgear, motor control, and medical device applications, where it is used for providing efficient and reliable galvanic isolation.
