Tunnel Diode

隧道二极管

The tunnel diode has a region in its voltage current characteristic where the current decreases with increased forward voltage, known as its negative resistance region. This characteristic makes the tunnel diode useful in oscillators and as a microwave amplifier.

隧道二极管在其电压-电流特性曲线中有一个区域，当正向电压增加时电流会减小，这一区域称为负电阻区。这一特性使得隧道二极管在振荡器中得到应用，并可作为微波放大器使用。
