Introduction to BJT (Bipolar Junction Transistor)

WebThe BJT die, a piece of a sliced and diced semiconductor wafer, is mounted collector down to a metal case for power transistors. That is, the metal case is electrically connected to the collector. A small signal die may be encapsulated in epoxy. In power transistors, aluminum bonding wires connect the base and emitter to package leads. WebThus, the BJT transistor consists of two pn junctions, connected back-to-back. These are called the emitter-base junction (EBJ) and the collector-base junction (CBJ). The circuit symbols for both kinds of BITs are shown in Figure 1. BJTs are asymmetrical devices, i.e. the collector and emitter regions are dissimilar. phn swslhdWeb• For a BJT to be biased in the active or linear operating region the following must be true: a. The base-emitter junction must be forward biased, with a resulting forward biased voltage of about 0.7v. b. The base-collector junction must be reverse-bias voltage being any value within the maximum limits of the device. phn sws mental health referral
