Now in this post you will learn about this amazing BJT device which is called Darlington Transistor. It got this name after genius engineer Sidney Darlington who first gave this idea, so we remember him. What Is Inside Darlington Transistor Basically this device is like special combo of two normal NPN or PNP bipolar junction […]

How MOSFET Works like a Switch
Now in our earlier talks we saw that the N-channel Enhancement-mode MOSFET or e-MOSFET works nicely when we supply it with positive input voltage, so this is very important to remember. This type of MOSFET has very high input resistance, almost close to infinity, and because of that we can use it easily like a […]
SCR/Thyristor Circuit Configurations
Now in this article we will try to understand step by step how we can use this thyristor in practical work. That can be for controlling heavy loads like electric lamps, heaters, or motors and so on. So this part is more about real application and not only about theory. How We Trigger The Thyristor […]
Understanding Bipolar Junction Transistors (BJTs)
If we look at the diodes, their internal construction look very simple. They are made by joining two pieces of semiconductor material, and this is called a pn-junction. But when we talk about bipolar junction transistor or bjt, then things get little more complicated. It needs adding one more layer of semiconductor material, and that […]
