There are two types of basics of bipolar transistor construction. The ability or we can say that the capacity of the transistor’s to change between these two states that are n and p enables it to have two basic functions: that is “switching” to digital electronics or the “amplification” that is analogue in electronics. The diodes which are two in number fusion produce a three layer of the two junction and a three-terminal device which forms the basis of a Bipolar Junction Transistor or we can say BJT for short. This will result in providing us with two PN-junctions which are connected in series that are shared with a common N and P terminal.

Joining the individuals together which are of two signal diodes back-to-back. We already know that the diodes which are simple diodes are made up from two pieces of semiconductor material to form a simple pn-junction here, and we will also learn about their characteristics and properties.
