WebMar 3, 2024 · Construction of Bipolar Junction Transistor. The BJT is formed by three layers of semiconductor materials, if it is a PNP transistor, it will have two P-type regions and one N-type region, likewise, if it is an NPN transistor, … WebNext, let’s consider the pnp transistor. Suppose that the collector potential is lower than the emitter potential and that the base potential is roughly 0.7 V lower than the emitter potential. In the case of the pnp transistor, electrons are injected into the n-doped base region. Therefore, holes are attracted from the emitter into the base ...
