Is semiconductor diode better than vacuum diode?

Answer 1

at thebeginning of electronic technology the vacuum tube was used in electronic circuit. .but now a days semiconductors are used in electronic circuit

Answer 2

It depends on the application. Each has its benefits. Most of the time, the semiconductor is better.

The vacuum diode is today costly and used only rarely, for special purposes.

examples of vacuum diode use:

Need a very linear Vf/current curve extending nearly to 0 volts. Even today, that function can be done almost perfectly with an op-amp circuit.

Need a high voltage rectifer that will tolerate overvoltages, arcing, and other electrical abuse.

Need extreme reverse resistance.

Some musicians and audiophiles prefer them, believing they contribute to the sound characteristics of an amplifier by affecting the way the power supply responds to changing loads

Military use, EMP-proof. A tube diode is definitely the under dog for a diode. It needs cathode power source and the voltage drop across is very hi making it impossible to carry a lot of current as opposed to silicone semiconductor type. And i don't understand why musician will like this type of device. it only produce DC and DC is never ending. Possibly it may refer to the dynamics of tube amplifiers which i do agree have better dynamics of sort.

Answer 3

Integrated circuits use semiconductor material for the electrons to flow, and variations in the type of material to control the flow. Vacuum tubes use an electron beam and a voltage applied to a grid to slow down or speed up the electrons. One major difference in practice, is that vacuum tubes require much more power to operate, and generate much more heat than semiconductors. For some high power applications (guitar amps, radio transmission), vacuum tubes may be the best tool for the job.

Answer 4

An integrated circuit is any circuit that is integrated into a single chip. A differential (amplifier?) circuit is a specific type of circuit, which can be built from discrete parts, but is often built into (analog) integrated circuits (ICs) as a fundamental component of the IC.

Answer 5

A: An IC can perform many functions while the tube can only amplify. The IC is very small in size1000:1 ratio. the IC is very power efficient compered to a tube. To add the IC chip is even smaller then the actual size most of the bulk is plastic and it is needed to route internal wire connection to the external terminals

Answer 6

An integrated circuit uses transistors instead of vacuum tubes. Transistors and vacuum tubes can do the same things, in terms of how they alter the flow of an electric current in a circuit, however, vacuum tubes are much larger, and they are also much less reliable, since they will eventually burn out, unlike transistors. So with transistors you can do a lot more. Even though the earliest electronic computer (ENIAC) was made with vacuum tubes, nobody today would want to attempt to build a computer with vacuum tubes.

Answer 7

• A circuit board has several components soldered to it, some of these components may be integrated circuits.
• The circuit board may be changed or rewired by hand, an integrated circuit cannot normally be changed or rewired (except for some Programable Logic Device integrated circuits, which can be changed electronically).
• A circuit board is typically made of fiberglass-epoxy or paper-epoxy with copper traces connecting the components, a monolithic integrated circuit is made of a semiconductor (e.g. silicon, gallium arsenide) typically with aluminum traces connecting the components, a hybrid integrated circuit is typically made of ceramic.

Answer 8

No difference both are active devices THE DIFFERENCE maybe in understanding that an IC may contain thousands of transistors

Answer 9

In simple words, an IC is a combination of more than 100's of transistors where are a transistor is a single device

Answer 10

Difference between vacuum tube and semi conductor
