Question

What is the difference between Transistor and Thyristor?

Answer 1

Hint: Semiconductors include transistors and thyristors. They are now widely used in switching operations because of their numerous advantages, including noiseless operation due to the absence of moving parts, very high switching speed (say 109 operations per second), high efficiency, low maintenance, small size, light weight, and long-term trouble-free service, large control current range (say from 30 A to 100 A) with small gate current of a few mA, and large control current range (say from 30 A to 100 A) with small gate current of a few mA.

Complete answer:

Parameters	Transistor	Thyristor
BASIC	It is a three-layer device that is used for amplification.	It is a four-layer device that is used for rectification.
JUNCTION	It has two intersections.	It is made up of three intersections.
DEVICE TRIGGERING	A steady current pulse must be delivered to the gadget to guarantee good conduction.	To start and maintain conduction, it takes a single triggering pulse in the initial state.
POWER RATING	It has a Watts rating.	It has a kilowatt rating.
COST	Cost-effective	It is more costly than a transistor.
SIZE	Smaller and less bulky in size.	It is bigger than a transistor because of its greater size.
CURRENT RATING	It is rated as having a poor current rating.	In the case of thyristor, the current rating is rather high.
Turn-on time	It activates more quickly than a thyristor.	It takes longer for this gadget to switch on.
Commutation circuit	It is not necessary.	Required.
Power Losses	It has a significant amount of power loss.	The power loss of a thyristor is lower than that of a transistor.
Suitability in application	It's best for high-frequency applications, but not high-power ones.	It's best for high-power applications, but not high-frequency ones.

Note:
A transistor is a three-layer, three-terminal device constructed of semiconductor material. The name transistor is a combination of the words "transfer" and "resistor." This basically describes how the transistor works. It is a device that shifts resistance from one location to another in order to assure conduction and hence increase the signal's strength. A thyristor is a four-layer semiconductor device with three terminals. The term thyristor comes from a combination of the phrases thyratron and transistor. It functions as a thyratron for rectification and as a transistor for control.
