Web• 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. WebDec 26, 2024 · Open-collector is a type of switched load driver circuit, along with open-emitter and push-pull. The terms 'open-collector' and 'open-emitter' are used when the switching component is a bipolar junction transistor (BJT), as collector and emitter are BJT terminals. If the switches are FETs, 'open-drain' and 'open-source' are used. green asia agri ventures inc

"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. " - Bjt collector emitter
