So when the emitter-base junction is forward biased, the variation of I E with V EB is … WebDec 26, 2024 · What about PNP transistors? PNP’s work a lot like the NPN’s — they have the same four modes — but everything is turned around. To find out which mode a PNP transistor is in, reverse all of the and > signs. For example, to put a PNP into saturation V C and V E must be higher than V B. You pull the base low to turn the PNP on, and make it ...
WebMay 31, 2024 · α = Output current/Input current = DC current gain for base circuit. In a common base NPN transistor, collector current (IC) is output current, and emitter current is input current (IE). \alpha =I_ {C}/I_ {E} The value of the current gain (α) is very close to unity and a bit less than the unity.
Class-B amplifiers uses Complementary or Matched Pair (that is one PNP and one NPN connected together) transistors in its output stage or in reversible H-Bridge motor control circuits where we want to control the flow of current evenly through the motor in both directions at different times for forward and … See more Basically, in this type of transistor construction the two diodes are reversed with respect to the NPN type giving a Positive-Negative … See more Also, all the polarities for a PNP transistor are reversed which means that it sinks current into its Base as opposed to the NPN transistor which … See more The construction and terminal voltages for an NPN transistor are shown above.
