Products within the single rectifier diode family are used to allow current flow in one direction only, and implement exactly one instance of this function per device package. Diodes used for other purposes (including zener and variable capacitance diodes) are listed separately in product families of their own, as are products incorporating multiple diodes per device package.

What are Diodes?

Diodes are utilized to safeguard circuits by limiting voltage and converting AC to DC. They are primarily made from semiconductors like silicon and germanium. While diodes allow current to flow in one direction, the method of transmission varies. Different types of diodes exist, each designed for specific applications.

Diode Symbol

The standard symbol for a diode is illustrated above. In this diagram, there are two terminals referred to as the anode and cathode. The arrowhead indicates the anode, showing the direction of conventional current flow when the diode is forward biased. The opposite end represents the cathode.
