Diodes are two-terminal semiconductors that allow current to flow through in only one direction.
Current Limiting Diodes (37 suppliers)
Current limiting diodes (CLD) regulate current over a wide voltage range. There are several types of current limiting diodes (CLD). Examples include a current regulator diode, constant current diode, and current limit diodes.

Diode Arrays (106 suppliers)
Diode arrays are composed of multiple discrete (usually unconnected) diodes on a single silicon chip. Diode arrays are important semiconductor products because they save assembly time and improve reliability over individually packaged diodes. In general, diode arrays use four or more diodes in a single package.

Diodes (753 suppliers)
Diodes are electronic components that conduct electric current in only one direction, functioning as a one-way valve. Diodes are manufactured using semiconductor materials such as silicon, germanium or selenium and are used as voltage regulators, signal rectifiers, oscillators and signal modulators / demodulators.

Gunn and IMPATT Diodes (17 suppliers)
Gunn diodes or transfer electron devices (TED) exhibit a negative resistance region. They are used in high-frequency applications, often for building RF oscillators. Impact ionization avalanche transit-time (IMPATT) diodes are designed to operate at very high frequency and power. They are used as elements in RF and microwave devices.

High Voltage Diodes (70 suppliers)
Photodiodes (232 suppliers)
PIN Diodes (69 suppliers)
PIN diodes are three-layer semiconductor diodes consisting of an intrinsic layer separating heavily doped P and N layers. The charge stored in the intrinsic layer in conjunction with other diode parameters determines the resistance of the diode at RF and microwave frequencies.

Schottky Diodes (166 suppliers)
Schottky diodes in their simplest form consist of a metal layer that contacts a semiconductor element. The metal / semiconductor junctions exhibit rectifying behavior (i.e., the current passes through the structure more readily with one polarity than the other).

Step Recovery Diodes (34 suppliers)
Step recovery diodes produce an abrupt turn-off (step) time by allowing a very fast release of stored charge when switching from forward to reverse bias, and from reverse to forward bias.

Transient Voltage Suppressor Diodes (TVS) (134 suppliers)
Transient voltage suppressor (TVS) diodes are designed to limit over-voltages. They can dissipate high amounts of transient power in a short period of time.

Tunnel Diodes (20 suppliers)
Tunnel diodes are heavily doped P-N diodes in which electron tunneling from the conduction band in the N-type material to the valence band in the P-type region produces a region of negative resistance. This negative-resistance region is the most important area of operation. As the voltage is increased, the current decreases. This feature makes tunneling diodes especially useful in oscillators and radio frequency (RF) applications.
