What do you
know about bipolar transistor leakage current
the whole of
output current is slightly less than the input current due to leakage current, for example in common
base transistor connection , the whole
of emitter current does not reach the collector . It is because a small percent
of it is lost, as a result of electron-hole
combinations occurring in the base area.
Also since
the collector to base region is reversed biased some leakage current flow due
to minority carriers, therefore the total collector/ output current
1) Part of emitter current which reach the collector terminal.
2)
The leakage current which is due to movement of minority carriers across
the base –collector junction account of being reversed biased.
Therefore
the bipolar transistor leakage current is the due to the effect of minority
carriers.
