Top 5 Varactor Diode Manufacturers in the World

A kind of diode that has varieties of internal capacitance with the reverse voltage is known as a varactor diode. The diode works in reverse bias conditions and is a voltage-dependent semiconductor device. A varactor diode is also known as Varicap, Voltcap, Voltage variable capacitance, or Tunning diode. In this diode, the component depends on its input voltage.  This diode has two terminals- anode and cathode. One end of a symbol consists the diode, and the other end has two parallel lines that represent the conductive plates of the capacitor. The gap between the plates shows their dielectric. Here, we have enlisted the top varactor diode manufacturers in the world;

ToshibaToshiba offers an extensive portfolio of diodes, including high-speed, low-loss Schottky-barrier diodes (SBDs) and TVS diodes (ESD protection diodes ) for high-speed signal lines.

Fabricated using silicon carbide (SiC), SiC SBDs provide high breakdown voltage that has never been possible with silicon (Si) SBDs. SiC SBDs are ideal for low-loss, high-efficiency power conversion applications such as server power supplies and solar power conditioners. Toshiba is continually working to improve the quality and reliability of its products. Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress. Toshiba has achieved its name among the top varactor diode manufacturers in the world.
