Best Answer

These types of transistors are power transistors and generate heat. The heat sink is used to dissipate the heat. If the transistor gets too hot it will fail.

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 are the advantages of collector to base biased?

it converts it to a diode. sometimes this is done for matching the characteristics of diodes and transistors in the circuit. standard diodes might not have similar enough curves to the transistors for the circuit to operate correctly.


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 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).


Can you see transistors?

Basically, in transistor, the signal is transferred from low resistance circuit to the high resistance circuit. So it is called transfer+resistor=Transistor.Transistors are widely used in different types of switching, amplifiers, oscillators and integrated circuits.Based on the applications, the types of the transistors are as given below:General purpose transistors, Low frequency transistors, High frequency transistors, Power transistors, Switching transistors, Field Effect Transistors, MOSFET, Uni-junction Transistors, Bi junction transistors, Photo transistor, High power transistors, Complementary pair, Darlington amplifier, Video and R.F. amplifier, Ultrahigh frequency and microwave, Insulated gate bipolar transistors, Static induction transistors.More their to know about transistors are as given below:History of invention, Time-line throughout, Basic construction, Bias arrangement, working, Various currents in transistors, Basic transistor amplifier, Configurations, Characteristics, Current gain and relation among them, D.C. load line, Operating point, Biasing of transistor, stability factor, specifications and ratings, testing, colour coding, identification of transistor using multimeter, h-parameter of transistor, particular applications etc...

What is the need to study transistors?

It is a need to study transistors because it concerns science and would help you find a work concerning technology more easily.But be careful of the effects of electricity as it will harm you.

What is the fullform of lfm in heatsink?

lfm in heatsink is "linear feet per minute" which is a unit for measuring airflow. Heatsinks are rated to work differently at different airflow which are measured in lfm or sometimes m/s (meters per sec)
