An optocoupler, also known as an optoisolator or photocoupler, is an electronic device made up of an LED emitter combined with a photodetector, separated from each other in proximity. There are many types of photodetectors, most of which are variations on a photodiode or phototransistor.

Current-sensing techniques are intrusive, meaning that somehow they will affect the system performance. It’s usually necessary to insert “something” in the middle of the path that goes from the power source to the load through which the current that we need to monitor flows.

This article reports the results obtained from an electrical characterization under high temperatures (25°C and 100°C), where forward voltage and reserve current were monitored for a set of 130 devices. The optimization process for these devices reflects an excellent behavior in on mode and a right compromise in a reverse way for the chosen application.
