SMV1270-040LF

Overview

The SMV1270-040LF is a single varactor diode manufactured by Skyworks Solutions Inc., designed for surface-mount applications in the SOD-882 package. It features a maximum peak reverse voltage of 20 V and operates within a temperature range of -55°C to 125°C. Key electrical specifications include a capacitance of 9.8 pF at 2.5 V reverse bias and 1 MHz frequency, with a capacitance ratio of 2.7 (C0.5/C2.5). The device complies with RoHS3 standards and has a moisture sensitivity level of 1.

Feature Summary

• Single configuration varactor diode optimized for RF tuning circuits
• Compact SOD-882 surface-mount package for space-constrained designs
• Wide operating temperature range suitable for diverse environmental conditions

Applications

• RF tuning circuits requiring variable capacitance control
• Voltage-controlled oscillators (VCOs)
• Frequency synthesizers and phase-locked loops (PLLs)

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS3 compliance and MSL rating during incoming inspection. Review official discontinuation notices for final purchase deadlines and last-time buy information before integrating into new production schedules.

Selection Notes

Select this component when a single varactor with 20 V reverse voltage capability is required in an SOD-882 footprint. Ensure design parameters align with the 9.8 pF nominal capacitance and 2.7 capacitance ratio. Validate thermal management for operation up to 125°C junction temperature. Consider alternative active components if long-term supply assurance is critical given the discontinued status.

Part Context

This part belongs to the SMV1270 series of varactor diodes from Skyworks Solutions. It shares the SOD-882 package form factor with other devices in the lineup but differs in electrical characteristics such as reverse voltage and capacitance values. The series targets RF applications where compact size and precise tuning are necessary.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Designers should consult Skyworks Solutions for recommended alternatives or evaluate compatible varactors with similar C-V characteristics and package dimensions.
