Working Principles

The U641B-MFPG3Y is an optocoupler that utilizes a phototransistor to provide electrical isolation between input and output circuits. When an input current is applied to the LED inside the optocoupler, it emits light that activates the phototransistor. The activated phototransistor then allows current to flow from the collector to the emitter, effectively amplifying and switching the signal.
