Title: Zener Diode Markings
Post by: Summa on June 14, 2022, 12:55:01 PM
Hi, there's a Zener diode in the kit with the markings 24 28, can't tell if that's the Z12V that I'm looking for as it says 22 in the docs

For those that struggle with the diodes (like me, old eyes), this is what was in my bag. As I had a hard time reading the exact markings, it took me a while. All references based on documentation package 24 and of course things may change when replacements from other parts manufacturers are used due to availability issues.
