Types of Diodes

small signal diode
Small signal diode - Low voltage/current diodes.

power rectifier
Power rectifier - High voltage/current diode.
bridge rectifier
Bridge rectifier are are four diode pre-installed into one component, useful for converting AC to DC.
zener diode
Zener diode - Designed to have a specific reverse voltage breakdown, meaning that it will stop current flowing until it reaches it's breakdown voltage and then it will allow current to flow.
led
Light Emitting diode (LED) - diode made from some substances (like Gama Arsenide Phosphide) emit visible radiation ( light ) when forward biased (current allowed to flow).
photodiode
Photodiode - While all diode are effected by light to some degree, some are extremely sensitive to light and change to work only in the presence or absence of light.
