晶体管

二极管也是半导体材料制作，但不是晶体管 a diode only has two terminals (anode and cathode) and allows current to flow in one direction, whereas a transistor has three terminals (emitter, base, and collector)

• Bipolar Junction Transistors
  • NPN or PNP transistors Explained
• FETs - Field-Effect Transistors
  • Mosfets 普通晶体管是电流控制元件，通过控制基极电流达到控制集电极电流或发射极电流的目的，到信号源必须提供一定的电流才能工作。 MOS管则是电压控制元件，它的输出电流决定于输入端电压的大小，基本上不需要信号源提供电流，所以它的输入电阻很高，这是它的突出特点。它广泛应用于放大电路和数字电路。
• hybrid - combines features of MOSFETs (a type of transistor) and BJTs (like NPN/PNP transistors). It’s designed for high-power applications, blending the best of both worlds.
  • IGBT IGBT逆变器 Insulated Gate Bipolar Transistor with 3D Animation

A Triode (Historical Predecessor) is largely replaced by transistors but foundational to electronics history, it’s an older vacuum tube device (not a transistor) that amplifies signals, while a transistor is a semiconductor device.

注意中文的“三极管”目前也是默认值“晶体三极管”或晶体管
