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 you need over voltage protection in dc motor?
Provide thermal stability by keeping winding I2 R losses within design limits and also extend brush life
How do monolithic ICs provide good thermal stability?
all the parts in the IC were made together so they have nearly identical characteristicsthe parts are close together in the IC so are probably at nearly the same temperature
Thermal runaway is not possible in FET because of?
Thermal runaway is not possible in FET because of?
If bandwidth of amplifier reduced then thermal noise in amplifier?
thermal noise willbe reduce
What are the disadvantages of PVC ceiling?
limited thermal stability
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.
How do you check transformer oil thermal stability?
An Oil Dielectric Strength Tester is the standard for qualifying Transformer Oil. Thermal Stability would involve heating and then testing. I do not know of a product which controls heat and applies the HV test.

Why Thermal stability increases when going down the group?
Thermal stability increases down a group because the atomic size increases, leading to weaker intermolecular forces and greater distance between atoms, making it harder for the atoms to come together and react. Additionally, the lower electronegativity of larger atoms down the group makes them less likely to form covalent bonds with other atoms, enhancing their thermal stability.
Is thermal system stable or unstable?
Thermal systems can exhibit both stable and unstable behavior. The stability of a thermal system depends on factors such as the design, operating conditions, and control mechanisms in place. Proper design and control can help maintain stability in thermal systems, while deviations from optimum conditions or factors like inadequate insulation or poor heat transfer can lead to instabilities.
