Generally speaking, we try to avoid operating diodes in their reverse breakdown region, but Zener diodes are the exception to this rule. Generally speaking, we try to avoid operating diodes in their ...

The Zener diode is similar to a general-purpose signal diode which consists of a silicon PN junction. It is a special kind of diode in which current is allowed to flow in the forward direction in the ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...
