Not exactly but base current raises exponentially with Vbe. I think it is 
possible to burn trannies by exceeding their base current if theres no
emmiter resistor, or base resistor.

Btw. For what purpose do you want to burn them ;-)

Actually in a switch application Vbe might exeed Vc which is about 0.1-0.2V
for the 
switch fully on.
