Collector Leakage Current
The collector current that takes place
when no base current is flowing is
referred to as Leakage Current.
Most modern transistor exhibit
extremely low values of leakage
current, often less than 1µA, even for
very high collector-emitter voltages.
Older Germanium types however can
suffer from significant collector leakage
current, particular at high temperatures
(leakage current can be very temperature
dependant).
If your transistor is a Silicon type, you should expect to see a leakage current of
close to 0.00mA unless the transistor is faulty.
