"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. " - Bjt emitter collector

WebThe BJT is a bipolar junction transistor whereas MOSFET is a metal oxide semiconductor field-effect transistor. A BJT has three terminals namely base, emitter, and collector, while a MOSFET has three terminals namely source, drain, and gate. BJT’s are used for low current applications, whereas MOSFET is used for high power applications. WebAn emitter-to-ground “feedback” resistor is usually found in common-emitter circuits as a preventative measure against thermal runaway. Negative feedback also has the advantage of making amplifier voltage gain more dependent on resistor values and less dependent on the transistor’s characteristics.

WebSep 8, 2024 · FIGURE 1. An NPN transistor looks like a pair of diodes back-to-back. The base-emitter diode is forward-biased while the base-collector diode is reverse biased. Note that the collector current does not flow to the emitter through the reverse-biased base-collector diode. Instead, it flows direct to the emitter via “transistor action”. WebMar 19, 2024 · The bipolar junction transistor shown in Figure below (a) is an NPN three layer semiconductor sandwich with an emitter and collector at the ends, and a base in between. It is as if a third layer were added to a two layer diode. If this were the only requirement, we would have no more than a pair of back-to-back diodes.
