A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect transistor, uses only one kind of charge carrier. A bipolar transistor allows a small current injected at one of its terminals to control a much larger current flowing between the terminals, making the device capable of amplificat… WebMay 22, 2024 · This page titled 4.3: BJT Collector Curves is shared under a CC BY-NC-SA 4.0 license and was authored, remixed, and/or curated by James M.

WebBJT can handle a lot more current than MOSFETs. One of the reason why they are still in use is BiCMOS applications where basically CMOS part is used as the logic and BJTs are used to drive very high capacitance nodes. Other than that, they have very nice properties regarding their PN junction nature.
