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 ...

The circuit has been constructed to test and measure the voltage rating of zener diodes. To be able to test the voltage rating of a zener diode up to 50 VDC, a small transformer and a single 555 timer ...

Normally, when you want a low DC voltage from the AC line, you think about using a transformer of some kind. [RCD66] noticed that an AC monitor meter must have some sort of power supply but had no ...

[Afroman] is back again with another great tutorial video on the basics of electronics. This time it’s zener diodes. Page three or four of every ‘beginners guide to electronics’ covers a diode as, “a ...

Central Semiconductor, manufacturer of discrete semiconductors, recently released the CMXSTB Series surface-mount stabistors packaged in the SOT-26 case. This new series consists of the 1.2-V ...

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.
