Thankfully, Adafruit has a video that explains how they work. Diodes protect your circuits by forcing the electrical current to go in a specific direction.

In most circuits the photo diode is reverse biased, so that charge is carried by extrinsic charge carriers. The response time of a photo diode is typically 250 nano seconds.

Discover the science behind diodes — the tiny components that control the flow of electricity. Learn how they let current pass in one direction, block it in the other, and power everything from ...

The discussion of how the diodes work reminded us of a modern tutorial we just ran across this weekend. It’s a bit bizarre, but explains the PN junction in a different way than we’re ...

Two of these were diode types. More examples of Williams VFC designs incorporating diode pumps are detailed in his fascinating (and entertaining!) narrative of his creative design process: “ The Zoo ...
