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.
Why do we not use point-contact transistors?
Point-contact transistors are largely obsolete due to their limited performance and reliability compared to modern bipolar junction transistors (BJTs) and field-effect transistors (FETs). They are more susceptible to thermal instability and noise, which can affect their operation in electronic circuits. Additionally, advancements in semiconductor technology have led to the development of more efficient and compact devices that offer better performance, making point-contact transistors less viable for contemporary applications.
Why are npn transistors used more often than pnp transistors?
The primary reason that NPN transistors are used more often than PNP transistors is that they usually operate faster (at higher frequencies) because the mobility of the current carriers in NPN transistors (electrons) is much higher than that of the current carriers in PNP transistors (holes).
What disadvantage of transistor did the circuit eliminate?
One significant disadvantage of transistors is their susceptibility to thermal instability, which can lead to fluctuations in performance as temperature changes. The circuit design may incorporate feedback mechanisms or temperature compensation techniques to stabilize the transistor's operation, thus mitigating issues like thermal runaway. Additionally, certain circuits may use complementary pairs of transistors to balance performance and improve efficiency, further addressing the inherent limitations of individual transistor components.
Where can I find output transistors to repair and amplifier?
You need to know the specifications for the transistors and search for them on the internet.
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.
What is thermal runaway in transistors?
The excess heat produced at the collector base junction may even burn and destroy the transistor.This situation is called thermal runaway.

What can perform the same functions as transistors but they are larger give off more thermal energy don't last as long and are tube shaped?
Vacuum tubes
What are power transistors?
Power transistors are transistors that are used in high-power amplifiers and power supplies.
Are transistors semiconductors?
Transistors are made out of semiconductors, yes.
Why Silicon transistor are preferred to germanium transistors?
Silicon transistors are preferred to germanium transistors because they exhibit higher thermal stability and are less prone to temperature variations. Silicon transistors also have a higher maximum operating temperature, improved frequency response, and are more reliable in terms of long-term performance. Additionally, silicon is more abundant and easier to work with in manufacturing processes compared to germanium.
