In electronics, a varicap diode, varactor diode, variable capacitance diode, variable reactance diode or tuning diode is a type of diode designed to exploit the voltage-dependent capacitance of a reverse-biased p–n junction.

The VariCap is an impalement protection cap that was designed by a construction professional. This impalement protection safety device is intended to protect workers from lacerations and falls from height. Tested to CAL/OSHA standard 344.90.

2024年1月3日 · A varactor diode, also called varicap, VVC (voltage-variable capacitance, or tuning diode, is a type of semiconductor diode which features a variable voltage-dependent capacitance on its p-n junction when the device is reversed biased.

在二极管大家族中，变容二极管（Varactor Diodes、Varicap Diodes，Tunning Diode）属于异类，在PN结反偏时结电容随外加电压的变化而变化，即反偏电压增大时结电容减小，反之结电容增大。

A varactor is a diode whose junction capacitance can be altered with an applied reverse voltage. For this reason, a varactor is also called a variable capacitance diode (also it's called a varicap). A varactor's capacitance varies as the applied reverse voltage to it changes.

The variable-capacitance diode is a product that makes use of the capacity characteristics of the depletion layer. The depletion layer occurs in the pn junction of the diode when the voltage is applied in the reverse direction, and the thickness varies in proportion to the reverse voltage.

Varicap diodes, also known as varactor diodes, are semiconductor devices engineered to exhibit a variable capacitance that is controlled by the reverse bias voltage applied across their terminals. At its core, a varicap diode leverages the properties of a PN junction to …
