MA26V0500A

Overview

The MA26V0500A 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 10 V and a junction temperature rating of 125°C. At 1 MHz, the diode capacitance ranges from 3.6 pF to 4.1 pF at 4 V reverse bias, yielding a typical capacitance ratio of 4.7 between 1 V and 4 V. The component utilizes an ML3-N2 surface mount package.

Feature Summary

• Engineered for VCO applications with high linearity in capacitance-voltage characteristics
• Provides a large capacitance ratio between low and moderate reverse bias voltages
• Minimizes signal loss through reduced series resistance at RF frequencies

Applications

• Voltage Controlled Oscillators (VCO)
• RF tuning circuits
• Frequency modulation modules

Procurement Notes

Verify current lifecycle status directly with Panasonic Industry, as this component may be classified under maintenance or discontinued stages. Confirm that the specific ordering suffix matches the required packaging format before finalizing procurement plans. Ensure compliance with RoHS directives applicable to your region.

Selection Notes

Select this component when a high capacitance ratio and low series resistance are critical for oscillator stability. The 10 V reverse voltage rating supports standard tuning ranges. Verify that the ML3-N2 package dimensions fit the target PCB layout constraints and that the operating frequency aligns with the specified electrical characteristics.

Part Context

This part belongs to the MA26V05 series of silicon epitaxial planar variable capacitance diodes manufactured by Panasonic Electronic Components. The series is specifically optimized for RF tuning applications requiring stable performance across varying temperatures and bias conditions.

Replacement Considerations

Consult official Panasonic documentation for confirmed substitute part numbers. Cross-referencing requires matching the ML3-N2 package, 10 V reverse voltage rating, and similar capacitance ratios to ensure functional compatibility.
