Table of Contents
Switching diodes are fundamental electronic components, akin to transistors and ICs, and are categorized as active components. In contrast, resistors and capacitors are referred to as passive components.
These diodes are fabricated from semiconductors such as silicon, germanium, and gallium arsenide.
Diodes generally function to maintain a steady current and voltage, and they allow current to flow only in a predetermined direction.
Switching diodes are characterized by their brief switching time, the period needed to switch from a state of conduction, where current flows in one direction, to an interrupt state when the current’s direction is reversed.
In electronic circuits, switching diodes perform two main roles:
Diodes, such as transistors and ICs, are semiconductors, which share properties of conductors, like metals, and insulators, like plastics.
Metals efficiently conduct current due to the mobility of electrons as free carriers. Application of voltage to metals leads to the flow of electric current carried by these free electrons.
Semiconductors, however, can function as both conductors and insulators, depending on the applied current’s state.
P-type and N-type semiconductors differ in how they facilitate current flow. P-type semiconductors, positively charged due to a lack of electrons, rely on electron movement to fill 'holes,' while N-type semiconductors, negatively charged with surplus electrons, utilize these free electrons to conduct current.
Switching diodes, formed by combining P-type and N-type semiconductors, are recognized for their fast-switching times and small size, making them ideal for small-signal processing applications.
