Photodiode, Phototransistor – Working and Application Circuits
Photodiodes and phototransistors are semiconductor devices which have their p-n semiconductor junction exposed to light through a transparent cover, so that external light can react and force an electrical conduction […]
Optocouplers – Working, Characteristics, Interfacing, Application Circuits
OPTOCOUPLERS OR OPTOISOLATORS are devices that enable efficient transmission of DC signal and other data across two circuit stages, and also simultaneously maintain an excellent level of electrical isolation between […]
Triacs – Working and Application Circuits
A triac can be compared to a latching relay. It will instantly switch ON and close as soon as it’s triggered, and will remain closed as long as the supply […]
