1.Diode :-a semiconductor device with two terminals, typically allowing the flow of current in one direction only.
2.Zeher diode:-a form of semiconductor diode in which at a critical reverse voltage a large reverse current can flow.
3.Transistors:-A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.
4.Semiconductor:-A semiconductor is a substance, usually a solid chemical element or compound, that can conduct electricity under some conditions but not others, making it a good medium for the control of electrical current.
Use of above devices
1.Diodes can be used as rectifiers, signal limiters, voltage regulators, switches, signal modulators, signal mixers, signal demodulators, and oscillators. The fundamental property of a diode is its tendency to conduct electric current in only one direction."
2.Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits. When connected in parallel with a variable voltage source so that it is reverse biased, a Zener diode conducts when the voltage reaches the diode's reverse breakdown voltage."

A transistor is a semiconductor device used to amplify or switch electronicsignals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.
Semiconductor material is used in the manufacturing of electrical components and used in electronic devices such as transistors and diodes. They can be classified into mainly two categories known as intrinsic semiconductors and extrinsic semiconductors.Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits. When connected in parallel with a variable voltage source so that it is reverse biased, a Zener diode conducts when the voltage reaches the diode's reverse breakdown voltage.
