Difference between Zener breakdown and Avalanche breakdown

The diode is a unilateral electronic device. It has two terminals termed – Cathode and Anode. When the diode is forward biased i.e., the anode is kept at a higher potential than the cathode, then ideally, the diode acts as a short circuit (zero resistance) and a large current will pass through it even if … Read more

Difference between Proton and Neutron

Proton and neutron are the particles that are found at the center of an atom and both particles comprise the nucleus. Apart from electrons, protons and neutrons form the nucleus of an atom. In this article, we will discuss what is the difference between proton and neutron. Difference between Proton and Neutron in tabular form … Read more

Types of Diode and Diode Applications

The diode is a two-terminal electronic component made up of semiconductor materials such as silicon, gallium, etc. It is a unidirectional device i.e. it allows current flow only in one direction. A diode is an uncontrolled device. There are different types of diode. The internal resistance of an ideal diode is considered as zero in … Read more

Avalanche Diode – Symbol, Characteristics and Applications

Like Zener diode, avalanche diode is a semiconductor diode that operates especially in the reverse-biased region. It is a type of PN junction diode having the same symbol as the Zener diode. The avalanche diode is designed in such a way that it can withstand the avalanche breakdown without being damaged by the suddenly and … Read more

Varactor Diode – Symbol, Characteristics and Applications

Varactor diode is a type of PN junction diode that behaves as a variable capacitor under varying reverse-biased voltage applied to its terminals. It shows this capacitive effect under reverse biased condition only. It has two terminals i.e. anode and cathode. It is also known by other names such as tunning diode or voltage variable … Read more
