WebA Bipolar Junction Transistor (BJT) is a bipolar device because its current is comprised of both electrons and holes. The parameter β is not often found in a data sheet. Instead, the forward DC value of β is listed as hFE, which is the large-signal current gain. A related parameter, hfe, is the small-signal current gain. WebIn the case of BJT, the base-emitter region is connected in the forward bias, and the base-collector region is connected in the reverse bias. Types of BJT. There are two types of Bipolar Junction Transistor, NPN transistor and PNP transistor. NPN Transistor. The NPN transistor consists of one P-doped region between the two N-doped regions.
