p-n junction diode circuit diagram working & curve

Earlier we have discussed the intrinsic and extrinsic types of semiconductor material. Semiconductor materials are used to develop many electronic devices. A p-n junction diode is one of those devices. In this article, we are going to discuss the formation, characteristics curves, depletion layer, potential barrier, bias circuit diagram, working principle and uses of a … Read more

Use of Zener Diode as Voltage Regulator

We have learned about the Semiconductor materials and some semiconductor devices like p-n junction diode, Bipolar junction Transistor (BJT) etc. There are variety of semiconductor diodes and they have different purpose. Sometime, we need a device which can give a constant output voltage at any value of input. This will protect the devices from the … Read more
