Control voltage and current in circuits with a variety of diodes.

Standard diodes keep the current in a circuit flowing in one direction. Use them to manipulate signals or to protect your circuit from reverse currents, such as those created when a motor stops or slows down.

Schottky diodes have faster switching speeds than other diodes, so they’re used to channel current in a single direction in circuits that switch frequently. They’re often found in radios and data processors.

Zener diodes regulate voltage in a circuit. When installed in reverse, they won’t conduct current until a set voltage is reached. After that point, they maintain the same voltage. Because they provide a stable voltage, they are often used as a reference point in amplifiers and other voltage-sensitive circuits.
