Overview
The SMV2023-000 is a silicon hyperabrupt junction tuning varactor diode from the 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. At 4 V, the capacitance ranges from 4.40 pF to 5.40 pF, while at 20 V, it ranges from 0.90 pF to 1.20 pF. The typical capacitance ratio (CT @ 4 V / CT @ 20 V) is 4.20, with a minimum quality factor of 500 at 4 V and 50 MHz.
Feature Summary
- Hyperabrupt junction design optimized for high capacitance ratios at low reverse voltages
- Low series resistance characteristics suitable for low phase noise applications
- Moisture Sensitivity Level 1 rated for lead-free soldering up to 260 °C
Applications
- Low phase noise Voltage-Controlled Oscillators (VCOs) in wireless systems
- RF and microwave VCOs
- Phase shifters
Procurement Notes
Verify the specific package marking and suffix against official Skyworks documentation before procurement. Confirm Moisture Sensitivity Level 1 handling requirements are met during storage and assembly. Ensure ESD precautions are strictly followed during handling to prevent damage to the semiconductor junction.
Selection Notes
Select this component when a higher zero-bias capacitance is required compared to lower-numbered series variants. Evaluate the 4.20 typical capacitance ratio and 500 Q-factor at 50 MHz against circuit requirements. Verify that the 22 V reverse voltage limit accommodates the maximum tuning voltage in the target application.
Part Context
The SMV2023-000 belongs to the SMV2019 to SMV2023 series of silicon hyperabrupt junction varactors. This family includes variants such as the SMV2019, SMV2020, and SMV2022, which offer progressively higher capacitance values. All series members share similar electrical characteristics regarding reverse voltage limits and power dissipation ratings.
