What are the advantages of using transistor as an switch instead of diode?
Waqasnawaz
1. A transistor *is* a triode- this is the general name for any three-electrode electronic device.
2. Most people understand "triode" to mean a tride vacuum tube/valve.
3. The transistor
(i) needs no heated filament/cathode, so it uses much less power than a valve triode,
(ii) because of (i), transistors do not "burn out" with age, so they have much longer lifetimes, are much more reliable, and generate much less waste heat,
(iii) transistors can operate at much lower power than triode valves, and at much higher frequencies,
(iv) transistors can be made much smaller than triodes, by a factor of many tens of thousands,
(v) from early on, transistors were much cheaper than triode valves.

When both junctions of NPN diode are reverse biased then the diode is in which mode?
Transistor will be in OFF mode.
Does a zener diode acts as a switch?
A zener diode cannot be used as switch.
What are the characteristics of Diode transistor logic?
relatively large propagation delay.
Can you use diode in place of a transistor?
no,we cant use transistor by combination of two diodes because we will come across a condition called current hogging.it means large amount of current flows through the device,diode can just rectify the signal but not amplifies it. Transistors however, can be used as diodes.
What happens when emitter and collector of a transistor are short?
The transistor acts like a normal pn diode. in NPN transistor the both n i.e.,collector and emitter ane shorted then they become a n and other is p so pn diode is formed. When the emitter and the collector of a transistor are short, the emitter current =the collector current.
What is Transit time in transistor or diode?
A transistor is a switch. A diode directs the flow of current.
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.
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.
Who is mostly used in the case of diode?
transistor//
When both junctions of NPN diode are reverse biased then the diode is in which mode?
Transistor will be in OFF mode.
When the both junction of npn diode is reverse biased then the diode in which mode?
Transistor will be in OFF mode.
When both junctions of NPN diode are reverse biased then diode is in which mode?
Transistor will be in OFF mode.
How can the bipolar junction transistor be used as a diode?
A: Yes it can but why ? This is frequently done when the diode is used for biasing purposes on another transistor and must be matched identically to the transistor's E-B junction characteristics. Thus 2 matched transistors are used with one just being used as a diode.
What is the disadvantage and advantage of photo diode and transistor?
photo diode donot work for long distance photo diode act as a receiver
Which semiconductor acts like a diode and two resistors?
uni junction transistor
