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 ...

These automotive-grade Zener diodes in SOD-523 packaging bring protection to entertainment, ADAS, BMS, and other space-constrained applications. Toshiba Electronics Europe’s XCEZ series of ...

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 ...

Toshiba has created a range of automotive-grade Zeners for surge protection in the 0.8 x 1.6mm SOD-523 package. Called the XCEZ series, they rated at 150 or 300mW (see below) and come in 20 E24 values ...

We always enjoy [w2aew’s] videos, and his latest on zener diodes is no exception. In it, he asserts that all Zener diodes are not created equal. Why? You’ll have to watch the video below to find out.
