SMV2025-040LF

Overview

The SMV2025-040LF is a silicon surface mount hyperabrupt tuning varactor diode manufactured by Skyworks Solutions, Inc. It operates within a reverse voltage range of 0 to 20 V and features a minimum capacitance ratio of 2.2 at 2 V to 10 V. The device exhibits a typical capacitance of 5.10 pF at 2 V and 1.25 pF at 18 V, with a series resistance of 0.8 Ω at 470 MHz. Packaged in the ultra-small SOD-882 format, it offers a parasitic inductance of 0.45 nH and supports a junction temperature up to 175 °C.

Feature Summary

• Hyperabrupt doping profile designed for wide bandwidth voltage-controlled oscillators and phase shifters
• Ultra-small SOD-882 package providing very low parasitic inductance and capacitance
• Low series resistance and leakage current characteristics optimized for low phase noise applications

Applications

• Wide bandwidth and low phase noise voltage controlled oscillators (VCOs)
• Wide range, voltage-tuned phase shifters and filters
• Miniature RF and microwave tuners

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via the official Certificate of Conformance. Ensure storage conditions adhere to Moisture Sensitivity Level 1 guidelines to prevent soldering defects during assembly.

Selection Notes

Select this model when an ultra-small footprint is required alongside high-Q performance. The SOD-882 package provides lower parasitic inductance compared to larger SC-79 variants. Verify that the 20 V maximum reverse voltage rating aligns with the specific circuit bias requirements.

Part Context

This component belongs to the SMV2025 series of silicon hyperabrupt tuning varactor diodes. The -040LF suffix specifically designates the SOD-882 surface mount package variant, distinguishing it from the SC-79 packaged SMV2025-079LF model within the same product family.

Replacement Considerations

The datasheet notes competitive cross-reference capability with Toshiba 1SV280 varactor diodes. Verify pinout compatibility and electrical parameter alignment before substituting.
