Due to my involvement with electronics and the posts I've made about diodes, I thought it would be neat to create some diode graphics (Github) under CC-BY-NC-SA (Creative Commons Attribution Noncommercial Share-Alike).
On the Github repository, there are SVGs for all three diode types, with rendered PNGs at 45, 90, 180, and 360 DPI. So here's the rundown:
Small Signal Diode (signal.svg, signal-rounded.svg)
This is simply a small-signal diode that is commonly found in a clear glass casing. Perhaps the most recognizable form of diode out there.
Germanium Diode (germanium.svg, germanium-rounded.svg)
This specific germanium diode icon simply has a nice arrangement of color patterns. The color patterns indicate that it would be a 1N651 diode, which doesn't exist!
Rectifier/Power Diode (rectifierpower.svg, rectifierpower-rounded.svg)
Lastly, just the simple power diode- clean and straightforward.
