Transcription: In this lesson, we will examine Zener diodes. There are several variants of the basic diode. A common variation is called a Zener diode. It is essentially a diode fabricated to operate in the reverse breakdown region. The arrow in the symbol points toward the cathode in the opposite direction of the forward bias current or electron flow. To demonstrate the response of a Zener diode to a reverse polarity voltage, we may use the circuit shown. An important characteristic of a Zener diode is the availability breakdown voltage. Unlike the case with an ordinary semiconductor diode, if the breakdown ...
