Hello, friends, I hope you all are doing great. In today’s tutorial, we will discuss the Difference Between Diode & Transistor. The basic difference between diode and transistor is that diode is used to transforms AC current into the DC but transistor transfers input signal from less resistive circuitry to a circuit having a large value of resistance. The name of diode is crystal diode since it is created with the crystals of silicon and germanium. A diode has two terminals anode and cathode it starts operation when the anode is attached with the positive terminal of battery and cathode with the negative terminal of the battery.

There are 3 terminals of transistor emitter-base and collector. The emitter is largely doped so it can send a large amount of charge carrier to the base region. The base has a small area and less doped so charges can move to the collector. A collector is the third region of the transistor and has a large area than the other two since it can dissipate heat generated at the base-collector junction. In today’s post, we will have a detailed look at both diode and transistor compare them to find their differences. So let’s get started with Difference Between Diode & Transistor.

Difference Between Diode & Transistor

Diode

A diode is a semiconductor instrument that used to transform ac into the dc.
A diode is used in the rectifier circuit and the process is known as rectification.

The diode has 2 terminals anode and cathode.
It is an uncontrolled switch.
The types of a diode are Junction diode, LED, Photodiodes, Schottky diodes, Tunnel, Varactor and Zener diode, step recovery,
It has two regions N and P. N has minority charge carriers and P has holes’ charge carriers.
There is one depletion region in the diode.
It is desinge with the usage of 2 differnt P and N mateial
P region is psotive and N is negative
As silicon can withstand high temperature used to make diode also germanium used for diode creation for less voltage applications

Transistor

The transistor is also a semiconductor device that used to send signals having weak strength for less resistive circuitry to a circuit having a large value of resistance.
Its common applications are Regulator, Amplifier and Rectification

It has three terminals which are emitter-collector and base.
It Fet there is single charge carrier exist in BJT two charge carries exist

In FET there is a single charge carrier and in BJT two charges carries used for concution.
The size of the transistor is less than the tube and uses less enrgy.
It is a controlled switch.
Its common types are BJT and FET JFET, MOSFET.
It works as a switch and amplifier

There are four mode of operation it has forward bias reverse saturation and cutoff
It has three regions which are emitter-base and collector.
There are 2 depletion regions exits in the transistor.
