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 ...

Abstract: Innovation in GaN semiconductors has improved aspect of power capability, switching speed and size. However, their short-circuit withstand time is low compared to SiC and IGBT switches. It ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

The presented solution for measuring voltage of Zener diodes using Arduino is completely new and original. The circuit uses LM317 as a constant current source and the whole measurement process is ...

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.

There are limitations to older circuit protection solutions that use Transient Voltage Suppressor (TVS) diodes. Responding to this situation, completely new transient current suppressors utilize ...
