Part 3: Diode Types
There are many
different type of diodes.
diodes are designed to stop electricity from flowing in the
Emitting Diode or LED is probably the most well known and most
easily identified. The LED emits visible light when electrons cross
the PN junction. It is available in several colours.
conduct only when they are exposed to light.
are designed to conduct in the reverse direction: the breakdown
voltage is engineered to precise tolerances.
diodes are designed to turn on and off very rapidly when the
threshold voltage is reached, providing very fast response times
in digital circuits.
