SMV1413-004LF

Overview

The SMV1413-004LF is a silicon abrupt junction tuning varactor diode from the Skyworks SMV1405 to SMV1430 series, housed in an SC-79 package. It features a typical capacitance of 6.4 pF at 1 V reverse bias and 4.1 pF at 4 V. The device exhibits a low series resistance of 0.35 Ω at 500 MHz and supports a maximum reverse voltage of 30 V with a forward current rating of 20 mA. Designed for high-Q resonators, it operates within a temperature range of -55 °C to +125 °C.

Feature Summary

• Low series resistance optimized for minimizing phase noise in Voltage Controlled Oscillators (VCOs)
• High Q factor suitable for high-frequency wireless system applications
• Moisture Sensitivity Level 1 rated for lead-free soldering processes

Applications

• High-Q resonators in wireless system VCOs
• High volume commercial systems requiring tight capacitance tolerances

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and lead-free status via official datasheets. Ensure handling follows ESD precautions and moisture sensitivity guidelines during storage and assembly.

Selection Notes

Select this component when a single varactor with moderate capacitance and low series resistance is required for VCO designs above 10 GHz. Compare against other series members like SMV1405 or SMV1430 based on specific capacitance ratios and package availability needs.

Part Context

This part belongs to the SMV1405 to SMV1430 family of plastic-packaged abrupt junction tuning varactors. These devices are characterized for capacitance over temperature and are designed for use in VCOs requiring tight capacitance tolerances.

Replacement Considerations

SMV1413-079LF serves as a functional substitute within the same series, offering identical electrical characteristics but packaged in SOT-23 instead of SC-79.
