diode is a bipolar device and transister is a three terminal device
a diode will conduct any time there is a positive voltage from cathode[-] to anode[+] following an exponetial curve of the diode.
a transistor can control the same exponential curves by a voltage applied to the base.

What is the difference between a 1N4007 diode and a 1N4007S diode what does the s do?
The difference in the 1N4007 diode and the 1N4007S diode is the voltage. The 1N4007S has a higher voltage but the meaning of the S is not listed.
The metal lead of p type of one pn diode connected to the metal lead of p type of another pn diode makes a npn transistor?
No. You cannot create a transistor by connecting two diodes together. There is an interaction between the junctions of a transistor, said interaction being not possible when two diodes are connected together.
What is difference between a diode and a photo diode?

What is another name for depletion mode transistor?

Why the n-jfet is operated with the negative voltage not the positive voltage?
In a JFET the only insulation between the gate and the channel is a reverse biased diode junction, if this junction becomes forward biased then the gate and channel are effectively shorted and the device no longer acts as a transistor (it will act as a forward biased diode instead). In the n-channel JFET, the gate is the P-side of this diode and the channel is the N-side of this diode. To keep this diode reverse biased (and the device operating as a transistor) therefor the gate MUST always be maintained at a voltage more negative than the most negative section of the channel.
What is Transit time in transistor or diode?
A transistor is a switch. A diode directs the flow of current.
What is the difference between detector and diode detector?
difference between detector and diode
Can you use diode as trangister?
A: YES but not directly. for instance a discrete differential amplifier one side need to be a transistor to recover gain but the other transistor can be a diode since in real time that is the operative base to emitter current difference. .
How transistor work as a diode?
A: Actually a transistor have two diode with the base mas a common terminal. the characteristics of these tow diodes however are not the same as a common diode
Can you use transistor as diode?
its the simplest thing to do. There are three legs in a transistor, one each of collector, base and emitter. So if you need to use it as a diode, just connect either collector-base or emitter-base. Say, if you use an NPN transistor, then the base region will be the anode of diode and emitter or collector will be the cathode of the diode.
Is a diode like a transistor?
No. A diode is not like a transistor, and a transistor is not like (two) diode(s). Taken in isolation, the emitter-base and collector-base junctions of a transistor appear to be diodes, but they are coupled together so that the base-emitter current affects the collector-emitter current.
What is the difference between a 1N4007 diode and a 1N4007S diode what does the s do?
The difference in the 1N4007 diode and the 1N4007S diode is the voltage. The 1N4007S has a higher voltage but the meaning of the S is not listed.
Who is mostly used in the case of diode?
transistor//
What is the difference between an ideal zener diode and practical zener diode?
Zener diode is heavily doped pn junction diode.
Difference between gunn diode and pin diode?
gunn diode is transfered electron device & PIN diode is semiconductor device
Which is better as a switch diode or transistor?
Basically a diode is a combinstion of pN junction but the transistor is made with three terminals EMITTER,, BASE ,, JUNCTION.. and diode is just a combination of positive and negative terminal . diode and transistors are both used as a switch .. but a transistor is more widly udes than a diode. and diode has also very important in electronics DIGITAL SYSTEM to make the screen's ..and transistors are used in amplifiers the group of transistors make an amplifier . and we use a diode in seven segment display ....diode is small and carry less current due to its small size but transistor get large current. A2 A diode has two connections. It allows current to flow in one direction and not in the other. They are used for rectification in power supplies, detection of AM radio, blocking of current etc. A Transistor has three connections. Current is controlled between the emitter and collector, by a small current on the base. They are used as switches, amplifiers and regulators.
When both junctions of NPN diode are reverse biased then the diode is in which mode?
Transistor will be in OFF mode.
