Overview
The SMV2022-004LF is a silicon hyperabrupt junction tuning varactor diode from the SMV2019 to SMV2023 series, manufactured by Skyworks Solutions. It features a SOT-23 package with a common cathode configuration and an inductance (LS) of 1.5 nH. The device has a maximum reverse voltage rating of 22 V and a forward current limit of 20 mA. Electrical specifications at 25 °C include a capacitance range of 2.50 pF to 3.30 pF at 4 V reverse bias, and 0.60 pF to 0.85 pF at 20 V reverse bias. The typical quality factor (Q) is 500 at 4 V and 50 MHz. Operating temperature ranges from -55 °C to +125 °C.
Feature Summary
- Hyperabrupt junction design optimized for low phase noise voltage-controlled oscillators
- High capacitance ratio maintained at low reverse voltages
- Low series resistance characteristics suitable for RF and microwave applications
Applications
- Low phase noise voltage-controlled oscillators in wireless systems
- RF and microwave voltage-controlled oscillators

Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and lead-free status via official datasheets. Ensure proper ESD handling protocols are followed during storage and assembly. Check moisture sensitivity level ratings before soldering processes.
Selection Notes
Select this component when designing circuits requiring high capacitance ratios at low reverse voltages. The SOT-23 package suits space-constrained surface mount designs. Verify that the 22 V reverse voltage rating meets system requirements. Consider the 1.5 nH series inductance impact on high-frequency performance.
Part Context
The SMV2022-004LF belongs to the SMV2019 to SMV2023 series of silicon hyperabrupt junction varactors. This series offers various package options including SC-79, SOD-323, and SOD-882. The SMV2022 variant specifically provides higher capacitance values compared to lower-numbered siblings like the SMV2019.
Replacement Considerations
SMV2019-004LF, SMV2020-004LF, and SMV2023-004LF share the same SOT-23 package and common cathode configuration within the same series. Substitution requires verification of capacitance values and Q-factor specifications against original design requirements.
