Explanation / Answer

1. there are varies dc biasing in bipolar transistor. To limit on the allowable power dissipation of a transistor we should be SELF BIAS or UNIVERSAL BIAS (as name suggest widely used in positive for discreet transistor). In modern days CONSTANT CURRENT SOURCE BIAS is used as in IC,s . These will reduce the powere dissipation and definitely thermal runaway of BIPOLAR TRANSISTOR.
