Power transistor can conduct large amount of currents through it, more than small signal transistor. power transistor has a vertical structure and small signal transistor has horizontal structure.In power transistor quasi saturation region is present which is absent in the small signal transistor. In power transistor there is a inculsion of drift layer which is not there in the small signal transistor. Power dissipation is less in power transistor and it is more in small signal transistor. b.v.polytechnic,vasai pushkar vaity.
Photo transistor always work with solar power
what is the power rating of a transister
This question makes no sense. Please clarify.
in bc107 transistor b stands for the material i.e,silicon here and c stands for af low power signal
