SMV1255屬于分立半導體產品的二極管-可變電容（變容器可變電抗器）。由美國思佳訊公司制造生產的SMV1255二極管 - 可變電容（變容器，可變電抗器）可變電容二極管可按照電子可變電容器用途進行生產和分類，并且廣泛用于調諧和頻率合成應用。雖然大多數二極管的結電容都隨著所施加的反向偏壓增加而減小，并且能夠用作可變電容二極管，但專門作為此類器件銷售的產品在生產和分類時特別考慮了這種用途。

描述 Description

The SMV1247–SMV1255 series of silicon hyperabrupt junction varactor diodes are designed for use in VCOs with low tuning voltage operation. This family of varactors is characterized for capacitance and resistance over temperature. SPICE models are provided.
