MA26V0400A

Overview

The MA26V0400A is a silicon epitaxial planar variable capacitance diode designed for voltage-controlled oscillator (VCO) applications. It operates within an ML3-N2 package and features a reverse voltage rating of 6 V and a junction temperature limit of 125 °C. At 1 V reverse bias, the typical diode capacitance is 11.1 pF, decreasing to 6.4 pF at 3 V. The series resistance is specified as 0.35 Ω at 3 V and 470 MHz. Reverse current remains below 10 nA at 5 V.

Feature Summary

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

Applications

• Voltage-controlled oscillators
• Frequency modulation circuits
• Tuning networks in communication equipment

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer marking symbol '2H' against official Panasonic documentation. Confirm that the device matches the ML3-N2 package dimensions and pin configuration before integration into the design. Ensure compliance with RoHS directives applicable to your region.

Selection Notes

Select this component when designing circuits requiring precise tuning capabilities with minimal insertion loss. Evaluate the capacitance variation across the operating voltage range to ensure it meets the required frequency stability.
