The junction temperature is limited by the relationship between temperature and life, and the characteristics of the materials composing the transistor. Furthermore, transistors use minority carriers and thus are easily affected by temperature. In particular , if the temperature rises in a reverse-biased collector-base junction, carriers are generated without relation to the signal, the operating point shifts, and in the worst case thermal runaway occurs and the transistor becomes damaged. For this reason, the circuit must be designed so as to prevent the junction temperature from rising. Transistor deterioration occurs quickly when the junction temperature rises.

Is junction transistor and bipolar junction transistor are same?
Yes, the are different names for the same thing.
Why high noise in bipolar junction transistor?
In the case of Bipolar Junction Transistor current conduction is due to both holes and electrons. That's why noise is high in Bipolar Junction Transistor

A transistor is in active region when?
a transistor in active region when emitter junction is forward biased nd collector junction is reverse biased
How do you know if a transistor is a PNP or an NPN?
To know if a transistor is PNP or an NPN,the following should be verified:For a PNP transistor, the base-collector junction is forward biased while the base-emitter junction is reversed biased.For an NPN transistor, the base-emitter junction is forward biased while the base -collector junction is reversed biased.
