SMV1430-040LF

Overview

The SMV1430-040LF is a silicon abrupt junction tuning varactor diode manufactured by Skyworks Solutions, Inc. It is housed in an SOD-882 surface-mount package with a series inductance of 0.45 nH. The device supports a maximum reverse voltage of 30 V and a forward current of 20 mA. At 0.5 V reverse bias, the capacitance ranges from 0.96 pF to 1.06 pF, while at 30 V it drops to 0.27 pF–0.35 pF. Series resistance is typically 3.15 Ω at 500 MHz, yielding a quality factor of 1680 at 50 MHz. Operating temperature spans -55 °C to +125 °C.

Feature Summary

• Designed for Voltage Controlled Oscillators requiring tight capacitance tolerances
• Low series resistance suitable for high-Q resonators in wireless systems
• Packages rated MSL1, 260 °C per JEDEC J-STD-020

Applications

• High-Q resonators in wireless system VCOs
• High volume commercial systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and lead-free status via official datasheets. Check for discontinuation notices as some SKYWORKS components face end-of-life transitions. Validate package markings against official documentation to prevent counterfeit substitution.

Selection Notes

Select this component when low capacitance values are required for VCO applications above 10 GHz. Compare series resistance and Q-factor requirements against other members of the SMV1405 to SMV1430 family. Ensure the SOD-882 footprint matches the PCB layout constraints and thermal management needs.

Part Context

The SMV1430-040LF belongs to the SMV1405 to SMV1430 series of plastic-packaged abrupt junction tuning varactors. This group includes variants like SMV1405, SMV1408, and SMV1413, which offer different capacitance ratios and series resistances while sharing similar packaging and electrical characteristics.
