Surface Mount Transistor in Mobile Cell Phone and Their Function
Surface Mount Transistor or SMT Transistor is an SMD electronic component made up of semiconductor material like silicon or germanium. There are 2 types of Surface Mount Transistors:
NPN Type
PNP Type
There are three terminals of a transistor:
Ammeter (E) – Flows current on receipt of forward bias. Electrons are emitted in NPN transistors whereas PNP transistors emit ‘holes’.
Collector (C)– The…
