Because the transistor is made from a p-type semiconductor (P) and n (N), which brought the three pieces, causing the seam between joints or body substance 2 called junction (Junction) where the substance in the Middle will be a different type to compounds that are head and tail. There is a stand out for the continued deployment of 3 legs, so the transistor so it is divided into two types according to the structure of the substance used is: 1. PN p-type transistor (PNP) 2. n-type transistor (NPN) PN.
