Types Uses

There are several types of diodes. Rectifying diodes change low-current AC to DC in the charging system. Power rectifiers can handle larger currents in electronic power supplies. Zener diodes can function as voltage sensitive switches. They turn "on" to allow current flow once a certain voltage is reached. They are often used in voltage regulation applications. Light-emitting diodes (LEDs) are used for indicator lights and digital displays. And, photodiodes detect light for sensors.
