Overview
The SMV1213-040LF is a silicon hyperabrupt junction tuning varactor diode from the Skyworks SMV121x series, designed for low tuning voltage Voltage Controlled Oscillators (VCOs). It features a typical capacitance ratio of C1V/C4V = 5 and operates within an operating temperature range of -55°C to +125°C. The device has a maximum reverse voltage of 12 V and a forward current rating of 20 mA. Packaged in the SOD-882 outline with a package inductance (LS) of 0.45 nH, it is rated Moisture Sensitivity Level 1 (MSL1) at 260 °C per JEDEC J-STD-020.
Feature Summary
- Hyperabrupt junction design optimized for low tuning voltage VCO applications
- High capacitance ratio providing efficient frequency tuning capability
- RoHS-compliant and halogen-free Green™ packaging
Applications
- Low tuning voltage Voltage Controlled Oscillators (VCOs)
- High-volume commercial systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and lead-free status by checking the marking code 'J' on the SOD-882 package against official datasheets. Ensure handling follows standard ESD precautions due to the sensitivity of semiconductor devices.
Selection Notes
Select this component when a high capacitance ratio is required for low-voltage VCO designs. Verify that the SOD-882 footprint matches the PCB layout constraints. Consider the 0.45 nH package inductance for RF performance requirements at the target operating frequencies.
Part Context
The SMV1213-040LF belongs to the SMV121x family of silicon hyperabrupt junction varactors. This series includes variants like the SMV1212, SMV1214, and SMV1215, which differ primarily in their nominal capacitance values and package options such as SC-79 and SOT-23.
Replacement Considerations
Direct substitutes within the same series include the SMV1213-001LF and SMV1213-004LF, which share the SOD-882 package and similar electrical characteristics but may have different capacitance tolerances or markings.
