Transistors are fundamental semiconductor devices used to amplify or switch electronic signals and power. They are essential components in modern electronics, widely used in automation, control systems, and industrial applications. Common types include Bipolar Junction Transistors (BJTs), Field-Effect Transistors (FETs), and Insulated-Gate Bipolar Transistors (IGBTs). Key products in this category may encompass power transistors, signal transistors, Darlington pairs, and MOSFETs. These devices enable precise control of electrical currents, ensuring efficient operation in circuits, motor drives, power supplies, and communication systems. Their compact size, reliability, and high-speed switching capabilities make them indispensable in automation and industrial electronics.
