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.

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 ...

Circuit symbol: the diode symbol consists of a triangle pointing towards a line. The triangle represents the anode, and the line represents the cathode. Forward-biased diode: an ideal diode ...
