MA27V1800L

Overview

The MA27V1800L 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 6V and a junction temperature rating of 125°C. Key electrical characteristics include a typical diode capacitance of 3.00 pF at 1V reverse bias and 1.41 pF at 3V reverse bias, both measured at 1 MHz. The capacitance ratio (CD(1V)/CD(3V)) typically reaches 2.21. Series resistance is specified as 0.3 Ω at 3V reverse bias and 470 MHz.

Feature Summary

• Optimized for VCO applications with high linearity in capacitance-voltage characteristics
• Provides a large capacitance ratio between low and medium reverse bias voltages
• Minimizes signal loss through exceptionally low series resistance values

Applications

• Voltage Controlled Oscillators (VCO)
• General electronic equipment circuits
