SMV1235-001LF

Overview

The SMV1235-001LF is a silicon hyperabrupt junction tuning varactor diode from the Skyworks SMV123x series, housed in an SOT-23 package with a series inductance of 1.5 nH. It features a typical capacitance of 6.4 pF at 3 V reverse bias and a minimum breakdown voltage of 15 V. The device exhibits a low series resistance of 0.6 Ω at 500 MHz and supports operation up to frequencies exceeding 10 GHz. Electrical specifications include a maximum forward current of 20 mA and power dissipation of 250 mW.

Feature Summary

Hyperabrupt junction design optimized for low tuning voltage VCO applications
Low series resistance characteristics suitable for high-Q resonators
Moisture Sensitivity Level 1 (MSL1) rated for 260 °C soldering

Applications

Voltage Controlled Oscillators (VCOs)
High-Q resonators in wireless systems
High-volume commercial RF systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for discontinuance notifications prior to procurement. Ensure storage conditions adhere to moisture sensitivity guidelines to prevent damage during solder assembly processes.

Selection Notes

Select this component based on required capacitance ratios and series resistance values for specific frequency ranges. Evaluate thermal management requirements against the 250 mW power dissipation limit. Verify that the operating temperature range aligns with system environmental constraints.

Part Context

This part belongs to the SMV123x family of silicon hyperabrupt junction varactors designed for RF and microwave applications. The series offers various capacitance options across different packages to support diverse circuit requirements while maintaining consistent electrical performance profiles.

Replacement Considerations

SMV1235-001 is the non-RoHS equivalent of this component. Other members of the SMV123x series may serve as alternatives if capacitance values and package footprints are compatible with the existing design.
