Transistors were shortly thereafter replaced by integrated circuits, which further minimized size and lessened power requirements.
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).
You need to know the specifications for the transistors and search for them on the internet.
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.
No. The PNP and NPN transistors are exactly opposite each other in polarity. You cannot just replace one for the other without redesigning the circuit.
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...
Integrated circuits (in many microprocessor integrated circuits) containing many billions of transistors each.
vacuum tubes
Silicon chips replaced individual transistors and before that vacuum tubes (valves).
discrete transistors
Vacuum tubes were first replaced by transistors, and later by integrated circuits.
By the logic gate. Which is just a series of transistors within one package. This was replaced by the processor which is just a group of logic gates. Effectively all microchips and processors are made up of thousands or even millions of transistors... as well as resistors and capacitors.
ll
Transistors were first developed in 1947 by Bell Telephone laboratories. They replaced vacuum tubes, which were big, bulky, costly, and unreliable. Transistors are most often used to regulate the flow of an electrical current and to switch electricity on and off.
depends what part is blown. most likely the ouput transistors. in that case, just get them replaced. if it keeps happening, get them replaced with heavier duty transistors.
Transistors
A device such as a radio can be said to be transistorized when earlier designs are replaced by designs in which transistors replace vacuum tubes.
In general individual components (e.g. resistors, transistors, capacitors) cannot be repaired, they are replaced.
