Introduction
In the fast-paced world of electronics, discrete semiconductors remain fundamental components that underpin everything from household appliances to electric vehicles and smartphones. While integrated circuits (ICs) get much of the spotlight, discrete semiconductors provide the essential functions—like switching, amplification, and signal control—that make complex systems work.

What Are Discrete Semiconductors?

Discrete semiconductors are individual semiconductor devices that perform a single electronic function, unlike ICs which integrate multiple functions into one chip. These components are vital in designing electronic circuits where precision, isolation, or power handling is needed.

Key Types of Discrete Semiconductor Devices
