MA26V0900A

Overview

The MA26V0900A 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. At 1 MHz, the diode capacitance ranges from 8.4 pF to 9.2 pF at 3 V reverse bias, and 14.9 pF to 16.4 pF at 1 V. The capacitance ratio (CD1V/CD3V) typically falls between 1.69 and 1.87. Series resistance is specified at 0.35 Ω at 470 MHz under 3 V reverse bias. The component utilizes an ML3-N2 surface-mount package.
