MA27V0400L

Overview

The MA27V04 is a silicon epitaxial planar variable capacitance diode designed for voltage-controlled oscillator (VCO) applications. It features a reverse voltage rating of 6 V and a junction temperature limit of 125 °C. Electrical characteristics at 25 °C include a typical diode capacitance of 11.1 pF at 1 V reverse bias and 6.4 pF at 3 V reverse bias, measured at 1 MHz. The series resistance is typically 0.35 Ω at 3 V and 470 MHz. The component utilizes an SSS-Mini type package with dimensions of approximately 1.40 mm in length and 0.60 mm in width.

Feature Summary

Procurement Notes

Verify current lifecycle status through official Panasonic channels before procurement. The datasheet indicates maintenance or discontinuation stages may apply. Confirm RoHS compliance documentation and latest product standards directly with the manufacturer to ensure availability and specification accuracy for your specific design requirements.

Selection Notes

Select this component for designs requiring a compact surface-mount varactor with defined capacitance ratios. Ensure operating voltages remain within the 6 V reverse voltage limit and junction temperatures do not exceed 125 °C. Verify that the SSS-Mini package footprint aligns with your PCB layout constraints and automated assembly capabilities.

Part Context

The MA27V04 belongs to Panasonic's lineup of silicon epitaxial planar variable capacitance diodes. It is part of the MA27V series, which includes variants like the MA27V0700L and MA27V2200L. These components are engineered for RF tuning applications where stable capacitance variation under changing reverse bias is critical.

Replacement Considerations

Consult official Panasonic documentation for confirmed substitute part numbers. Cross-referencing with other manufacturers requires careful verification of pinout compatibility, electrical parameters, and package dimensions to ensure functional equivalence in existing designs.
