About PIN Diodes

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. This resistance typically ranges from kilohms to less than 1 ohm for a given diode. A PIN diode is typically used as a switch or attenuator element.

PIN diodes have an intrinsic semiconductor sandwiched between p-type and n-type semiconductor layers. A PIN diode is a semiconductor device that operates as a variable resistor at radio and microwave frequencies and that has the resistance value determined only by forward biased direct current. In switch and attenuator applications, PIN diodes control the radio frequency (RF) signal level without introducing distortion that might change the shape of the radio frequency signal. An important feature of PIN diodes is its ability to control large radio frequency signals while using much smaller levels of direct current excitation. A PIN photodiode is also another name for a positive-intrinsic-negative (PIN) diode. PIN photodiodes are semiconductor light detecting diodes with a particularly fast response time.

Products & Services Related to PIN Diodes

Current Limiting Diodes
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.
General Purpose Diodes
General-purpose diodes are electric components that conduct electric current in only one direction, functioning similarly to a one-way valve.
GUNN and IMPATT Diodes
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.
Rectifier Diodes
Rectifier diodes are designed for use in rectification circuits. Rectifiers are used to convert AC to DC.
Schottky Diodes
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
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.
Zener Diodes
Zener diodes are PN junction devices that are designed to operate in the reverse-breakdown region.
