Optoisolators - Transistor, Photovoltaic Output

The TIL117S(TB)-V is a type of optoisolator, which is an electronic component that utilises light to provide electrical isolation between two circuits. It has a photovoltaic output, meaning it has a single phototransistor output. As a result, the TIL117S(TB)-V optoisolator enables the transmission of signals between two circuits in a secure, safe, and high-powered manner, without allowing any energy to transfer between circuits physically.

Application Fields and Working Principles of TIL117S(TB)-V Optoisolators

Optoisolators, such as the TIL117S(TB)-V, are used in many applications from industrial and commercial ones to hobbyist projects. These include digital logic input and output interfaces, power supply regulator feedback loops, waveform monitoring, and safety circuits. As optoisolators provide electrical isolation, they also help protect sensitive devices from surges, voltage spikes, and other electrical interference.

The working principle of the TIL117S(TB)-V optoisolator is based around a light-emitting diode (LED) and phototransistor. The LED emits light when the device receives a electrical current, and the phototransistor will react to this light, activating the electric current when it receives enough light. As the LED and transistor are separate from each other, they are galvanically isolated, preventing the current from transferring across to the other circuit.

The TIL117S(TB)-V is particularly suited for low power applications as the phototransistor can handle a maximum of only 400 mA while the LED can control 75 mA. The device also has a high isolation voltage, allowing it to manage alternating current of up to 6000 Vrms. It is also compact and easy to install, measuring only 4.6mm x 4.7mm x 15.6mm. Additionally, the TIL117S(TB)-V contains a built-in shield that makes it even more effective at avoiding radio interference.

In summary, the TIL117S(TB)-V optoisolator is an ideal way to enable communication and transmission of signals between two circuits without allowing them to be electrically coupled. This device can handle moderate current and high voltage, and its compact size makes it easy to install. The built-in shield provides extra protection against radio interference. All this makes the TIL117S(TB)-V an ideal choice for a variety of industrial, commercial, and hobbyist applications.
