As basic components in hardware design, diodes, transistors and MOS tubes each have unique working principles, selection points and a wide range of application scenarios. In hardware design, accurately grasping the characteristics of these components and selecting them reasonably according to circuit requirements is the key to ensuring hardware system performance, stability and cost control.

Diode and transistor are two commonly used semiconductor devices in electronic circuits. There are many differences between them in structure, working principle, characteristics and application.

UnitedSiC UF3C065030K3S is a third-generation silicon-carbon (SiC) MOSFET produced by United Silicon Carbide (UnitedSiC). The device uses SiC material, which has higher switching speed, high temperature resistance and lower conduction loss compared to traditional silicon (Si)-based materials.

The D882 Transistor: Your All-in-One Solution for Amplification and Switching

The 7408 integrated circuit is a classic TTL (transistor-transistor logic) type IC, which is widely used in various digital circuits. It contains four 2-input AND gates, each with two inputs and one output, for performing logical AND operations.

hFE, also known as current gain or β (Beta), is an important parameter of the transistor, which represents the ratio between the base current and the collector current. It describes the gain capability of a transistor when amplifying current.
