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.
