The excess heat produced at the collector base junction may even burn and destroy the transistor.This situation is called thermal runaway.

What is minority charge carrier?
In semiconductor devices there are two types of charge carriers: electrons and holes. In N-type doped semiconductor the majority charge carriers are electrons and the minority charge carriers are holes. In P-type doped semiconductor the majority charge carriers are holes and the minority charge carriers are electrons.Some kinds of semiconductor devices operate using minority charge carriers in part(s) of their structure. The common bipolar junction transistor is one of these, they are sensitive to a phenomenon called thermal runaway because additional minority carriers are produced as temperature increases. (field effect transistors however operate using only majority carriers and are thus not sensitive to thermal runaway)
How many transistors are on a Phenom II 965?
758 Million transistors.
What are transistors used for?
Transistors have two basic functions: # an electrically controlled electric switch # an electrically controlled "proportional valve" which can alter currents and voltages, or can amplify electric signals. Transistors can also be configured as Oscillators which provide an AC signal with constant frequency. Either an amplifier circuit or a switching circuit can be wired as an oscillator. Transistors can be used to form logic gates: And, Or, and Invert. Computers are made from logic gates, so computers can be made entirely from transistors. Transistors are in use in virtually all electronic devices. PC processors are composed of millions of tiny transistors. A transistor radio may have had only 6-10 transistors to enable operation. A late model car may have 10 to 15 computers comprised of thousands of transistors to perform all manner of operations in the vehicle.
What are the laws in Maine concerning harboring a runaway. What will happen to the person harboring a runaway?
There is no law in the state of Maine, That will have you arrested for harboring a runaway.
What is btj transistors?
They are NPN and PNP. BJT mean bipolar junction transistors. there are two P-N junctions in BJT transisters.
What is stability of transistor?
Transistors need thermal stabilization because the operating point of a transistor junction, similar to a diode, is affected by temperature. In fact, this can cause thermal runaway, and device destruction, if the circuit design does not compensate for this. Answer mostly correct but the operating point of a transistor must remain fixed as temperature varies whether going low or higher. that is mainly the concern about. not runaway that is caused by bad design.
What is thermal stability of transistor?
The thermal stability is the ability of the transistor to withstand changes in temperature without the transistor's parameters changing. Transistors generally have poor thermal stability and in particular the Beta parameter increases with temperaure, which can cause thermal runaway in a badly designed circuit. This is well known and the bias current in transistors is normally stabilised by the application of negative feedback in proper circuit design.
