SMV2025-000

Overview

The SMV2025-000 is a silicon hyperabrupt junction varactor diode manufactured by Skyworks Solutions Inc. It is designed for high-frequency tuning applications requiring low series resistance and high capacitance ratios. The device features a single-diode configuration housed in an SC-79 surface-mount package, suitable for automated assembly processes. Key electrical characteristics include a peak reverse voltage rating of 22 V and a typical capacitance value of 0.65 pF at zero bias. The component operates within a temperature range of -55°C to +125°C (TJ).

Feature Summary

• Utilizes a silicon hyperabrupt junction design to achieve superior capacitance variation relative to applied voltage.
• Engineered with minimal series inductance and resistance to maintain high Q-factor performance at RF frequencies.
• Provides a compact surface-mount footprint compatible with standard SMT manufacturing lines.

Applications

• Voltage-controlled oscillators (VCOs) in wireless communication systems.
• RF phase shifters and tunable matching networks.
• Frequency synthesizers and PLL circuits.

Procurement Notes

Verify the specific suffix designation against official Skyworks documentation, as the SMV2025 family includes variants with different packaging or electrical tolerances. Confirm current lifecycle status, as several models in this series have reached end-of-life or are subject to discontinuation notices. Ensure compliance with RoHS3 standards if required by the target application environment.

Selection Notes

Select this component when a low-capacitance hyperabrupt varactor is needed for wideband tuning applications. Compare the C0/C30 ratio and series inductance specifications against circuit requirements to ensure adequate tuning range and insertion loss performance. Validate that the SC-79 package dimensions fit the available PCB real estate constraints.

Part Context

The SMV2025-000 belongs to the Skyworks SMV2025 series of hyperabrupt varactor diodes. This family is distinct from the SMV12xx and SMV14xx series, which typically offer higher capacitance values. The SMV2025 series is specifically optimized for applications requiring lower capacitance levels and higher operating frequencies compared to general-purpose tuning diodes.

Replacement Considerations

Publicly confirmed substitute part numbers for the SMV2025-000 were not identified in the provided reference data. Engineers should consult the manufacturer's official substitution guide or contact Skyworks technical support directly for validated alternatives.
