To measure a zener diode’s breakdown voltage, you need a dc voltage source whose voltage exceeds that of the zener voltage. In Figure 1, resistor R SER provides voltage drop between V IN and V ZEN. In ...

This Design Idea describes a versatile test circuit for zener diodes after yet another misread zener diode had infiltrated the ranks of 1N4148 diodes assembled on a pc board. As a bonus, the circuit ...

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.

Announced by America Semiconductor, LLC is the availability of a full series of power Zener diodes (part numbers: 1N3305 thru 1N3350) packaged in a DO-5 case. The robust 50 Watt devices are engineered ...

According to Microsemi, its new family of ultra-sharp knee Zener diodes offers four times the voltage regulation and a 40-fold improvement in typical lower leakage current versus comparable devices.

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 ...
