I have a BC337 transistor
I followed the formulas to get the on-off mode but I do not see 0volts when I apply 5 volts in the base, how it cab be possible to get a deep cut-off.
IB>IC/HFE
HFE=100
IC=14.15mA
I double the result
IB=2*Ic/HFE =.3mA
Vin=5votls
then
Rx=Vin/IB =16.666K
I am using a 15 Kohms resistor
with this value I have a 30mV at the colector pin
Thanks in advanced
