Overview
The SMV1236-011LF is a silicon hyperabrupt junction tuning varactor diode from the Skyworks SMV123x series, housed in an SOD-323 package with a series inductance of 1.5 nH. It features a typical capacitance of 17.02 pF at 1 V reverse bias and maintains a maximum reverse voltage rating of 15 V. The device supports a forward current of 20 mA and operates within a temperature range of -55 °C to +125 °C. Designed for low tuning voltage applications, it offers a high capacitance ratio and low series resistance suitable for high-Q resonators.
Feature Summary
- Hyperabrupt junction design optimized for low tuning voltage operation in Voltage Controlled Oscillators (VCOs).
- Low series resistance characteristics facilitate the creation of high-Q resonators for wireless systems operating above 10 GHz.
- Moisture Sensitivity Level 1 (MSL1) rated for lead-free soldering processes up to 260 °C.
Applications
- Low tuning voltage Voltage Controlled Oscillators (VCOs)
- High-Q resonators in wireless system VCOs
- High-volume commercial RF systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and lead-free status via official datasheets. Check for recent Product Discontinuation Notifications regarding end-of-life status. Ensure proper ESD handling protocols are followed during storage and assembly to prevent damage.
Selection Notes
Select this component when a specific capacitance value around 17 pF at 1 V is required for hyperabrupt tuning profiles. The SOD-323 package suits space-constrained surface mount designs. Evaluate the 1.5 nH series inductance impact on circuit performance at target frequencies exceeding 10 GHz.
Part Context
This part belongs to the SMV123x family of silicon hyperabrupt junction varactors. Other members include the SMV1231 through SMV1237, which offer varying capacitance ranges from approximately 1.4 pF to 45 pF. All share similar electrical characteristics but differ in package options such as SC-79, SOT-23, and SOD-882.
Replacement Considerations
SMV1236-079LF: Identical electrical specifications packaged in SC-79 format.
