Both p and n are the basic semiconductors arrived from the concept of doping. Hence the basic difference between p and n-type is the way or the nature of the doping involved. Semiconductors can be differentiated as intrinsic and extrinsic as per the matter of purity concerned. P-type and N-type semiconductors come under extrinsic semiconductors. Although they are categorized under the same category of extrinsic there behaviors are extremely different based on its dopants. However, they have … [Read more...]

What is an P-type Semiconductor?
A crystal that has its conduction value in between conductor and insulator is termed as the semiconductor.It can be formed by the addition of impurities. It can be referred to as either p-type or n-type. Hence its conduction is based on the types and the amount of impurity added. These solids conduction value is proportional to the temperature value. As the temperature increases its conduction value increases as temperature degrades then the conduction of the semiconductor tends to … [Read more...]

BC558 Transistor : PinOut, Specifications, Circuit, Working, Datasheet & Its Applications
The transistor like PNP operates almost similarly to NPN but the current directions & voltage polarities will be reversed. The flow of current in NPN is from the collector terminal to the emitter whereas in PNP, it is from the emitter terminal to the collector. So, a PNP transistor is generally a type of transistor where n-type material can be doped using two p-type materials. A PNP transistor is an electronic component that is controlled simply through the current supply. So the small … [Read more...]
