MA26V1500A

Overview

The MA26V1500A is a silicon epitaxial planar variable capacitance diode designed for voltage-controlled oscillator (VCO) applications. It operates with a maximum reverse voltage of 6 V and a junction temperature rating of 125 °C. Key electrical characteristics include a typical diode capacitance of 7.91 pF at 0.5 V reverse bias and 3.23 pF at 2.5 V reverse bias, measured at 1 MHz. The device achieves a capacitance ratio between 2.35 and 2.55 under these conditions. Series resistance is specified as low as 0.45 Ω at 470 MHz. The component utilizes an ML3-N2 surface-mount package.
