Bjt operated as switch
WebOct 6, 2016 · So, from the above explanation, we can conclude that bipolar junction transistor behaves as a switch only when it is operated in the cutoff and saturation region of its characteristic. In switching application, … WebSep 7, 2024 · The circuit is similar to that of the Common Emitter circuit. The difference is that we need to turn the transistor fully ON (saturated) or fully OFF (cut-off) to be able to operate it as a switch. An ideal transistor switch has infinite resistance between the Emitter and the Collector when it is turned fully-OFF leading to 0 current flow ...

WebWhen is a MOSFET more appropriate as a switch than a BJT? Answer: 1) a MOSFET is better than a BJT when: When you need really low power. MOSFETs are voltage-controlled. So, you can just charge their Gate once and now … WebJul 19, 2024 · Explanation: If BJT is to act as a switch with negligible power dissipation, then BJT is operated in the cut-off and saturation region, as in the TTL family. When BJT has to be operated as a fast switch, then it is operated in the active and cut-off region, as in the ECL family. What is a BJT circuit? What is a Bipolar Junction Transistor (BJT)?
WebThe control of the Drain current by a negative Gate potential makes the Junction Field Effect Transistor useful as a switch and it is essential that the Gate voltage is never positive for an N-channel JFET as the channel current will flow to the Gate and not the Drain resulting in damage to the JFET.
