As an example, with a 12-V input, using a 2.5-V Zener diode would require a 1.9-kΩ series resistor to maintain 5 mA (assuming no load current).

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 belo… ...

As active devices go, it doesn’t get much simpler than a diode. Two terminals. Current flows in one direction and not in the other. Simple, right? Well, then there are examples with useful si… ...

To set the static level at the input pin,you must enable the FPGA’s internalpulldown resistor to prevent the PCIclamp diodes from being driven too hardwhen the input is continuously high. The current ...

One common reference circuit, which several semiconductor manufacturers supply and which uses a buried-zener diode, is the REF02; you can couple a REF02 with an external op amp to obtain dual voltage ...
