No, it is not possible because in transistor the depletion layers formed in Emitter-Base Junction & Collector-Base Junction are penetrable by both current carriers but in this case of two diodes; the formed depletion region are not penetrable for current carriers (hole &electron). Also, a transistor works only because the base layer is very thin. You won't get that thin layer between emitter and collector just by connecting two diodes together. This thin base layer places the Emitter and Collector in very close proximity to each other. This allows majority carriers from the emitter to diffuse as minority carriers through the base into the depletion region of the base-collector junction, where the strong electric field collects them. In other words the emitter/base current flow draws some of the barrier charge away from the collector/base junction and allows collector/emitter current to flow across the base using minority carriers. So transistor action is not possible.
But we can make transistor by connecting two diodes and two dependent current sources i.e. Ebers-Moll model of transistor.
This is true only when you want to make the transistor act like a on/off switch, but you cannot make this setup of diodes to act like an amplifier. Whereas the transistor also acts as an amplifier too
A transistor can act as: (1) on/off switch (2) amplifier.
Diode is made up of two layers and one junction.
Transistor is made up of three layers and two junctions.

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 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.
Why diode act as an insulator?
Diode is a semiconductor material. so it act as insulator also.
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.
How transistor acts as a amplifier?
A transistor does not act as an amplifier. It is used as a component in an amplifier circuit.
Can a diode act as a source of emf?
NO
Can a transistor can act like resistor capacitor inductor?
A transistor acts like a resistor when Gate is connected to Source.
Why transistors are designed?
For switching applications transistor is biased to operate in the saturation or cutoff region. Transistor in cutoff region will act as an open switching whereas in saturation will act as a closed switch.
Is diode an active device?
A passive device is a diode resistor coil and so forth it perform no enhancement to the circuit or act on it.
Advantages of TTL?
To know about the advantages of TTL logic family, one should have a basic idea about RTL, DTL etc. Diode logic (DL) uses diodes to implement logical functions like AND and OR. But the disadvantage is that it can not perform NOT operation. As AND and OR are not complete functions by themselves, they can not perform several logic functions without NOT. Hence, there was a need for some device which can perform a NOT function as diodes can not. That device is a transistor. Then came the DTL which uses a transistor along with diodes. As a transistor can act as an inverter, NAND (NOT-AND) & NOR (NOT-OR) operations can be performed. But this logic uses several diodes which will slow down its operation. Due to the delay offered by them, the logic levels may sometimes change i. e. 0 t0 1 or 1 to 0. Then came TTL. This logic uses a multi emitter transistor, a transistor with many emitter terminals. As every emitter is nothing but a diode, this logic eliminates the use of all diodes. This is the major advantage. As transistor becomes ON and OFF much rapidly than a diode, switching time will be faster. TTL, or Transistor-transistor logic replaced resistor-transistor logic, and used much less power. The TTL family is very fast and reliable, and newer faster, less power-consuming, etc. types are always being developed. = In TTL (Transistor-Transistor Logic), think that the device using this technology is made from several transistors. Another advantage is that many more chips employ this technology.
What are the advantages of transistor-transistor logic?
Transistor-transistor logic (TTL) is a class of digital circuits built from bipolar junction transistors (BJT) and resistors. It is called transistor-transistor logic because both the logic gating function and the amplifying function are done by transistors.To know about the advantages of TTL logic family, one should have a basic idea about RTL, DTL etc. Diode logic (DL) uses diodes to implement logical functions like AND and OR. But the disadvantage is that it can not perform NOT operation. As AND and OR are not complete functions by themselves, they can not perform several logic functions without NOT.
