DISCRETE SEMICONDUCTORS

Discrete semiconductors are individual electronic components that are used for specific functions in electronic circuits. Unlike integrated circuits, which combine multiple components into a single package, discrete semiconductors are stand-alone devices that can be used in a variety of different circuit configurations.

Types of discrete semiconductors include:

  1. Rectifiers: These are semiconductor devices that convert AC voltage to DC voltage, and are commonly used in power supplies and battery chargers.
  2. Varistors: These are voltage-dependent resistors that protect electronic circuits from voltage surges and transients.
  3. Optocouplers: These are semiconductor devices that combine an LED and a photodetector to provide electrical isolation between two circuits.
  4. Voltage regulators: These are semiconductor devices that maintain a constant output voltage regardless of changes in input voltage or load current, and are commonly used in power supplies and voltage regulators.
  5. Diodes: These are semiconductor devices that allow current to flow in only one direction, and are commonly used for rectification, voltage regulation, and switching applications.
    • Schottky diodes: These are semiconductor diodes with a low forward voltage drop, and are commonly used in high-frequency circuits and power supplies.
    • Zener diodes: These are semiconductor diodes that operate in the reverse breakdown region, and are commonly used for voltage regulation and protection.
  6. Transistors: These are semiconductor devices that can amplify or switch electronic signals, and are commonly used in amplifiers, oscillators, and power switching circuits.
    • RF transistors: These are high-frequency transistors that are commonly used in RF amplifiers, oscillators, and mixers. 
  7. Thyristors: These are semiconductor devices that can control high-current, high-voltage signals, and are commonly used in power regulation and control circuits.
  8. MOSFETs: These are metal-oxide-semiconductor field-effect transistors that are commonly used as electronic switches in power electronics and inverter circuits.
    • Power MOSFETs: These are MOSFETs with a higher voltage and current rating, and are commonly used in power conversion and motor control applications.  

Applications of discrete semiconductors include:

  • Power supplies: Discrete semiconductors are commonly used in power supplies for regulating voltage and current.
  • Lighting: Discrete semiconductors are used in a variety of lighting applications, including LED drivers and power control circuits.
