    Common Application of Optocoupler in Today’s Electronic Circuits

    The most common application of Optocoupler is signal isolation. It provides complete isolation because its input side is not electrically connected to the output side. Its input side is a light source which is commonly a LED, while the secondary side is a photo transistor. A photo transistor is also a transistor but without a base current. The absence of

    Disadvantage of using Optocoupler with Low CTR for Switch Operation

    In optocoupler, CTR stands for current transfer ratio. This is comparable to the current gain beta in BJT. This is the most important parameters of an optocoupler to function normally. There are several factors that affect the CTR, read here. In this article we are going to focus what is the disadvantage of using Optocoupler with low CTR particularly in
