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.

∙ 13y agoA: a diode will not emit photons will have greater reverse voltage breakdown will conduct large amount of current its voltage drop can be predicted to be .6-.7 volts. LED will emit photon when excited will have a low voltage reverse breakdown because of its hi forward voltage drop the current will be into the ma range

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.

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 the difference between Transistor and resistor?
The difference between a Transistor and a Resistor is that a transistor is designed to amplify the electrical current, whereas a Resistor is designed to reduce the electrical current.
Who is mostly used in the case of diode?
transistor//

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.
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
When both junctions of NPN diode are reverse biased then the diode is in which mode?
Transistor will be in OFF mode.
