Types of Transistor

What is the types of transistor ?There are two main types of transistor. 1-Bipolar Junction transistor (BJT) 2-Field Effect Transistor(FET) Transistor Types Tree Bipolar Junction Transistor (BJT) Bipolar junction transistor have three terminals which is emitter ,base and collector. By control the flow of ...Read More

What is Schottky Diode?

 What is Schottky diode?It is a type of  diode that has less forward voltage drop than the P-N junction diode and can be used in high-speed switching applications. In Schottky diode ,p-type semiconductor is replace by metals such as aluminum or platinum. The  schottky ...Read More

What is Varactor Diode?

What is Varactor Diode?It is type of Diode whose internal capacitance varies with the variation of reverse voltage. This type of diode is used to store charges. The Varactor diode work always in reverse biased and it is voltage dependent semiconductor device.The term Varactor ...Read More

What is Tunnel Diode?

What is Tunnel Diode?Tunnel or Esaki Diode is a heavy doped P-N junction semiconductor device  which have negative resistance characteristic due to their quantum mechanical effect called tunneling  or it is type of diode in which the electric current decrease as the voltage increase. ...Read More

What is a Photodiode?

What is a Photodiode? It is a P-N junction type semiconductor device which generated electric current or voltage when it exposed to sunlight. In the photodiode between then P-type and N-type region an intrinsic layer s present. Light energy is used as input in ...Read More
