SMV1249-000

Overview

The SMV1249-000 is a single hyperabrupt junction silicon varactor diode manufactured by Skyworks Solutions, Inc. It is housed in an SOD-323 surface-mount package designed for RF and microwave applications. The device features a maximum reverse voltage of 15 V and a forward current rating of 20 mA. Key electrical parameters include a nominal capacitance of 18.18 pF at zero bias and a minimum quality factor of 750. The component operates within a temperature range of -55°C to +125°C.

Feature Summary

• Hyperabrupt junction design optimized for wide tuning ratios
• High Q-factor performance suitable for RF circuits
• Compact SOD-323 surface-mount footprint

Applications

• Voltage-controlled oscillators (VCOs)
• Electronically tunable bandpass filters
• Impedance matching networks

Procurement Notes

Verify the specific suffix against manufacturer documentation, as ordering codes may indicate variations in packaging or testing criteria. Confirm RoHS compliance status through official datasheets prior to integration. Ensure supply chain stability as availability varies by distributor.

Selection Notes

Select this component when a high tuning ratio is required for frequency synthesis or filtering. The SOD-323 package suits space-constrained designs. Verify that the 15 V reverse voltage rating meets the circuit's peak operating requirements.

Part Context

This part belongs to the SMV1249 series of plastic-packaged surface mount varactor diodes. The series includes variants with different capacitance values, such as the SMV1249-011LF, all sharing similar hyperabrupt junction characteristics and package outlines for consistent design implementation.

Replacement Considerations

Check for direct substitutes within the same Skyworks series or equivalent hyperabrupt varactors from other manufacturers. Ensure pinout compatibility and verify that replacement components meet the original Q-factor and capacitance tolerances.
