A 1N4148 diode with a higher forward voltage than the max 0.5volt in the Atmega datasheet also doesn't help that much. A zener diode is designed to operate in the reverse breakdown, or Zener, region, beyond the peak inverse voltage rating of normal diodes. Continuous reverse voltage : max. The 1N4148 is useful in switching applications up to about 100 MHz with a reverse-recovery time of no more than 4 ns. In the image of zener diodes the blue and red examples are labelled 5v1 and the smaller orange one is labelled BZX. When a Zener diode under test (zut) is placed across the output, the Zener will conduct at its breakdown voltage and the volt meter will display this voltage.
