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 ...

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 ...

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 ...

Toshiba Electronics has expanded its range of Zener diodes with a further 15 products to protect the power lines of semiconductor devices.

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.

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 ...

[Hans] wanted to see the frequency response of a bandpass filter but didn’t have a lot of test equipment. Using an RTL-SDR dongle, some software and a quickly made noise generator, he still managed to ...
