MA26V2000A

Overview

The MA26V2000A is a silicon epitaxial planar variable capacitance diode designed for Voltage Controlled Oscillator (VCO) applications. It features good linearity and a large capacitance ratio in the CD-VR relationship, alongside small series resistance. The device operates with a maximum reverse voltage of 6 V and a junction temperature rating of 125 °C. At 1 MHz, the typical diode capacitance is 19.5 pF at 1 V reverse bias and 9.90 pF at 3 V reverse bias. The capacitance ratio (CD(1V)/CD(3V)) typically ranges from 1.89 to 2.04. Series resistance is specified as 0.35 Ω at 3 V reverse bias and 470 MHz.
