transistor maximum voltage doubt?
if a a circuit with single transistor,which has the function of amplifying signals, input signal=5V. Circuit powered by 20V DC,
and the maximum Vcbo=36V,Vceo=16V,Vces=36V. ,Vebo=4V of the transistor.
then is there any chance of blowing up of the transistor.
actually i think "NO",because the supply voltage is less than the maximum voltages of the transistors.,but the doubt is the Vebo,which is 4V,but the input signal to the base will be 5V.
is there any any single chance of blowing up of the transistor

Vebo is not relevant, as that junction is rarely reverse biased. It is forward biased under normal operation and under those conditions the VBE never exceeds 1 volt.
But the 16 volt VCEO could be problem with a 20 volt supply. Considering the VCES spec is 36 volts, you are probably OK, but I can't guarantee it. It depends on the resistance value between base and emitter.
Actual breakdown will vary between BVCEO and BVCES depending on RBE.
I'd play it safe and use a higher voltage transistor or a lower supply voltage.

Of course... but it depends on what else is in the circuit. A traditional BJT amplifier uses some combination of resistors in the base, collector, and/or emitter and could be designed to perform adequately with these voltages.
