How a bjt can be used as a switch

WebTransistors, used to amplify and switch signals, heralded the modern electronics era. Two predominate transistors today include Bipolar Junction Transistors (BJT) and Metal-Oxide-Semiconductor Field Effect Transistors (MOSFET). MOSFET offers advantages over BJT in modern electronics and computers. Web10 de jul. de 2024 · So for a BJT to act as an open switch, all you need to do is to make sure that its base-emitter junction is not forward-biased. Now, for a BJT to act as a closed switch, it needs to operate in the saturation region.
