A transistor is not a diode. It is also not a pair of back to back diodes. Two diodes connected back to back will not function like a transistor because their junctions are not in close proximity like they are in a transistor.
The only reason for "thinking" that a transistor is "like" a pair of back to back diodes is for purposes of quick go-nogo testing with a multimeter, but that will only assess open, short, and leakage status, as well as polarity, but not any of the more useful things, such as hFe.
What else can I help you with?
What is Transit time in transistor or diode?
A transistor is a switch. A diode directs the flow of current.
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.
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
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.
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. .
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
What does SBDT stand for electrically?
SBDT stands for Schottky Barrier Diode Transistor, which is a type of semiconductor device that combines the functions of a Schottky diode and a bipolar transistor in a single package.
