Overview
The SMV1236-040LF is a silicon hyperabrupt junction tuning varactor diode from the Skyworks SMV123x series, housed in an SOD-882 (0402) surface-mount package. It features a maximum reverse voltage of 15 V and operates within a temperature range of -55°C to +125°C. Typical capacitance values are 18.50 pF at 1 V and 9.20 pF at 3 V, yielding a capacitance ratio of 2.0 at 1 V/6 V. The device exhibits a typical series resistance of 0.50 Ω at 3 V and 500 MHz.
Feature Summary
- Hyperabrupt junction design optimized for low tuning voltage Voltage Controlled Oscillators (VCOs).
- Low series resistance characteristics suitable for high-Q resonators in wireless systems.
- Moisture Sensitivity Level 1 (MSL1) rating compatible with 260 °C soldering processes.
Applications
- Low tuning voltage Voltage Controlled Oscillators (VCOs)
- High-Q resonators in wireless system VCOs
- High-volume commercial systems
Procurement Notes
Verify component authenticity against official Skyworks documentation prior to integration. Confirm that the specific ordering suffix corresponds to the required packaging format. Ensure handling procedures adhere to industry-standard electrostatic discharge precautions during storage and assembly.
Selection Notes
Select this component when a capacitance value near 18.5 pF at 1 V is required for hyperabrupt tuning applications. The SOD-882 package is appropriate for designs constrained by small footprint requirements. Verify that the 15 V reverse voltage limit aligns with the circuit's maximum operating bias conditions.
Part Context
This part belongs to the SMV123x family of silicon hyperabrupt junction varactors designed for RF tuning applications. The series includes variants such as the SMV1231 through SMV1237, differentiated primarily by their capacitance ranges and specific package options like SC-79 or SOT-23.
Replacement Considerations
Direct substitutes within the same series include the SMV1235-040LF and SMV1237-040LF. These alternatives offer different capacitance profiles while maintaining identical electrical limits and package dimensions.
