Ⅲ. Origin of Discrete Semiconductor
Discrete semiconductors are electronic components that are not integrated into a single chip, but rather consist of individual semiconductor devices packaged separately. Examples of discrete semiconductors include diodes, transistors, thyristors, and optoelectronic components such as light-emitting diodes (LEDs) and photodiodes.
Diodes are the simplest form of discrete semiconductor devices, and they are used primarily to allow current to flow in one direction while blocking it in the opposite direction. Transistors, on the other hand, are more complex and are used as switches or amplifiers. They can be either bipolar junction transistors (BJTs) or field-effect transistors (FETs).
Thyristors are another type of discrete semiconductor device that are used as switches, and they are often used in high-voltage and high-current applications. They include silicon-controlled rectifiers (SCRs), triacs, and diacs.
Optoelectronic components, such as LEDs and photodiodes, convert electrical signals into light or vice versa. LEDs are commonly used in display and lighting applications, while photodiodes are used as sensors to detect light or other electromagnetic radiation.
Discrete semiconductors are typically used in applications where precise control over electrical characteristics is required, or where the size and cost of integrated circuits are prohibitive. They are also used in applications where high power or high voltage is required, such as in power supplies, motor control, and lighting systems.
In summary, discrete semiconductors are individual semiconductor devices that are packaged separately, and they are used primarily in applications where precise control over electrical characteristics is required or where high power or high voltage is needed. They are a fundamental component of modern electronics, and they continue to play an important role in many applications today.
What is Discrete Semiconductor?
Discrete Semiconductor refers to a single semiconductor device rather than a circuit in an integrated circuit (IC). These devices are commonly used in a variety of electronic applications including power management, amplifiers, switches, voltage regulators, converters, filters, and more.
Common discrete semiconductor devices include diodes, transistors, field effect transistors (FETs), triodes, thyristors (SCRs), triacs (TRIACs), light emitting diodes (LEDs), photodiodes, voltage regulator diodes, etc. These devices can be categorized based on different characteristics and uses such as power, speed, operating temperature, and more.
Origin of Discrete Semiconductor
The origins of discrete semiconductor devices can be traced back to the early 20th century, when the first true semiconductor device - the transistor - was invented.
In 1947, three scientists at Bell Laboratories invented the first transistor, an invention considered a milestone in modern electronics. After the transistor, many other types of discrete semiconductor devices were invented, including diodes, field effect transistors, transistors, and more. These devices have different characteristics and applications, and are widely used in various electronic devices and circuits.
As technology advances, the performance of discrete semiconductor devices continues to improve, including improvements in power, speed, reliability, and more. Today, discrete semiconductor devices remain integral to many electronic applications and have contributed greatly to the development of modern electronics.
