A zener diode is like a normal silicon diode, where a forward biased diode will pass current ... including a diode clamping circuit. This circuit will clamp the voltage to a maximum of Vz ...

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 LEDs, regardless of their color. Place the forward-biased LED you would ...

They have none of the special skills you’d find in tunnel, Gunn, varicap, Zener ... biased Off position. To illustrate a basic diode switch, we’ve prepared a couple of simplified circuit diagrams.

For many years, designers used Zener diodes ... bias current for a load not shown. This application can use the lower-cost 2% E version of the LM4040-N device. As you can see, the circuit is ...
