Overview
The SMV1212-001LF 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. Electrical specifications at 25°C include a minimum reverse voltage of 12 V and a maximum reverse current of 20 nA at 8 V. Absolute maximum ratings specify a forward current of 20 mA, power dissipation of 250 mW, an operating temperature range of -55 to +125 °C, and a storage temperature range of -55 to +150 °C.
Feature Summary
- Hyperabrupt junction design optimized for low tuning voltage VCO applications
- High capacitance ratio with typical value of 5 at C1V/C4V
- Halogen-free Green™ product compliant with applicable legislation
- Moisture Sensitivity Level 1 rated for 260 °C soldering
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 via official datasheets. Check Moisture Sensitivity Level handling requirements before assembly. Ensure ESD precautions are followed during storage and transport to prevent damage.
Selection Notes
Select based on required capacitance ratios and reverse voltage limits. Verify package compatibility with SOT-23 or SC-79 footprints. Consider thermal management within the specified operating temperature range. Evaluate SPICE model parameters for circuit simulation accuracy.
Part Context
Part of the SMV121x series of silicon hyperabrupt junction varactors. Designed specifically for VCOs requiring low tuning voltage operation. Characterized for capacitance and resistance over temperature variations. Available in single, common cathode, and common anode configurations across various packages.
Replacement Considerations
SMV1213-001LF: Single configuration, SOT-23 package, LS=1.5nH. SMV1215-001LF: Single configuration, SOT-23 package, LS=0.7nH. SMV1213-079LF: Single configuration, SC-79 package, LS=0.45nH.
