Zener diodes keep voltage stable by allowing current to flow in reverse at a specific level. This video explains how they work and how Zener and avalanche breakdown help regulate voltage in circuits.

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 circuit was designed to provide a means for measuring the operating voltage of zener diodes before applying on a circuit. Zener Diode – a special kind of diode that permits the flow of current in ...

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 ...

Before there were bandgaps, voltage references ranged from neon glow tubes to Zener diodes. Paul Rako, with the help of Bob Pease and others, “drifts” back in time to trace their history. Back on ...
