MA27V0300L

Overview

The MA27V0300L is a silicon epitaxial planar variable capacitance diode designed for voltage-controlled oscillator (VCO) applications. It features a maximum reverse voltage of 6 V and operates within a junction temperature range up to 125 °C. The device exhibits a typical diode capacitance of 5.80 pF at 1 V and 2.58 pF at 4 V, measured at 1 MHz. The capacitance ratio between these voltages is typically 2.6. Series resistance is specified as 0.3 Ω at 4 V and 470 MHz. Reverse current is limited to 10 nA at 5 V. The component utilizes the SSSMini2-F1 surface mount package.

Feature Summary
