A simplified diode switch in the reverse biased Off position. To illustrate a basic diode switch, we’ve prepared a couple of simplified circuit diagrams. The first shows the anode tied to ground ...

A zener diode is like a normal silicon diode, where a forward biased diode will pass current with a ~1 volt drop. When a zener diode is reversed biased, there’s a different voltage drop ...

The voltage in Figure 4was measured at a zener-diode current of 2.8 mA. Figure 4 Measure the voltage across a zener diode with a digital multimeter. You can use the circuits in figures 2 and 3 to test ...

Diodes, one-way current conductors, are used for voltage regulation, AC/DC conversion, and circuit protection. Forward-biased at 0.6V, conduct current, reverse bias blocks it.

You can build a simple low-current voltage regulator from a resistor and a Zener diode. This type of regulator is often adequate for noncritical applications such as internal bias voltages. The ...
