WebIn cut off region, both emitter to base and base to collector junction is in the reverse bias and no current flows through the transistor. The transistor acts as an open switch. In the … WebThe region to the left of the knee is the saturation region. For switching applications, the BJT is most like a closed switch when it is in the saturation region, where VCE is small. It is most like an open switch when it is in cutoff, with iC = 0. A BJT is often used as a current-controlled switch, as illustrated in figure 3. can cheap credit explain the housing boom https://paulmgoltz.com

Why is saturation region called so in BJT characteristics?

Web• In order to prevent the BJT from entering very deeply into saturation, the collector voltage must not fall below the base voltage by more than 400 mV. V CC I C R C (V BE 400mV) A linear relationship can be derived for VCC and RC and an acceptable region can be chosen. Deep Saturation WebExplain Common Emitter characteristics of a BJT. THEORY. Structure of Bipolar Junction Transistor; A bipolar junction transistor, BJT, is a single piece of silicon with two back-to-back P-N junctions .BJTs can be made either as PNP or as NPN. ...

By increasing the V CE beyond 0.7v, the collector current remains constant for a given value of base current I B. Increasing the V CE can cause a very slight increase in I C because of the widening of the base-collector depletion region. fishing with paste tips

The break-over point is fairly small at just a few tenths of a volt. This can be found on a data sheet as \(V_{CE(sat)}\). The saturation region is used in transistor switching applications. At the extreme right is another region where the collector current rises rapidly. This is called the breakdown region.

Webmore.
