MA2SV0900L

Overview

The MA2SV0900L is a silicon epitaxial planar variable capacitance diode designed for Voltage Controlled Oscillator (VCO) applications. It features a single-diode configuration housed in an SS-Mini type package (EIAJ SC-79). The device supports a maximum reverse voltage of 6 V and operates at junction temperatures up to 150 °C. Key electrical characteristics include a typical diode capacitance of 16.4 pF at 1 V and 9.2 pF at 3 V, measured at 1 MHz. The component achieves a capacitance ratio of 1.87 under these conditions. Series resistance is specified as 0.35 Ω at 3 V and 470 MHz.

Feature Summary

• Good linearity and large capacitance-ratio in the C_D-V_R relation
• Small series resistance rD
• SS-Mini type package allowing downsizing of equipment and automatic insertion through taping

Applications

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

Procurement Notes

Verify current lifecycle status directly with Panasonic Industry, as this model may be discontinued or subject to maintenance plans. Confirm that the SS-Mini package dimensions align with your PCB footprint requirements. Ensure design parameters remain within the absolute maximum ratings, specifically the 6 V reverse voltage limit and 150 °C junction temperature threshold.

Selection Notes

Select this component when high capacitance ratios and good linearity are required for VCO tuning circuits. The low series resistance makes it suitable for higher frequency operations. Verify compatibility with standard surface mount assembly processes due to the small SS-Mini package size. Consider thermal management capabilities if operating near the upper temperature limits.

Part Context

This part belongs to the MA2SV09 family of variable capacitance diodes manufactured by Panasonic Industry. These components are silicon epitaxial planar types specifically engineered for RF applications requiring stable capacitance variation with applied voltage. The MA2SV0900L represents a specific variant optimized for general-purpose VCO designs.

Replacement Considerations

Consult official Panasonic documentation for verified substitute part numbers. Cross-referencing requires matching key parameters such as capacitance range, reverse voltage rating, and package type to ensure functional equivalence in existing circuit designs.
