SMV2019-000

Overview

The SMV2019-000 is a silicon hyperabrupt junction tuning varactor diode from the Skyworks SMV2019 to SMV2023 series. It features a maximum reverse voltage of 22 V and a power dissipation rating of 250 mW. The device operates within a temperature range of -55 °C to +125 °C. Electrical specifications include a capacitance at 4 V ranging from 0.65 pF to 0.95 pF, and a capacitance ratio of 2.30 between 4 V and 20 V. The typical quality factor (Q) is 500 at 4 V and 50 MHz. Reverse current is limited to a maximum of 50 nA at 16 V.

Feature Summary

• Low series resistance for low phase noise performance
• High-capacitance ratio at low reverse voltage
• Packages rated MSL1, 260 °C per JEDEC J-STD-020

Applications

• Low phase noise VCOs in wireless systems
• RF and microwave VCOs
• Phase shifters

Procurement Notes

Verify the specific package type and marking code required for your design, as the SMV2019 series utilizes multiple packages including SC-79, SOD-323, SOT-23, and SOD-882. Confirm that the ordering suffix matches the desired physical footprint and lead-free compliance status before finalizing procurement orders.

Selection Notes

Select the SMV2019 variant based on the required capacitance range and Q-factor for your specific frequency band. Ensure the operating voltage remains within the 22 V absolute maximum rating. Verify thermal management requirements against the 250 mW power dissipation limit during continuous operation.

Part Context

The SMV2019-000 belongs to the Skyworks SMV2019 to SMV2023 series of hyperabrupt junction tuning varactors. This family includes variants with different capacitance values and package options, designed specifically for applications requiring high capacitance ratios and low series resistance in RF circuits.

Replacement Considerations

Direct replacements must match the 22 V reverse voltage rating and similar capacitance characteristics. Verify pinout compatibility if substituting across different package types within the same series. Consult Skyworks documentation for updated equivalent part numbers.
