SMV2025 Series
Surface Mount, Silicon Hyperabrupt Tuning Varactor Diodes

The SMV2025 series are silicon surface mount, hyperabrupt tuning varactor diodes, excellent for use as high-Q tuning elements in an RF Voltage Controlled Oscillator (VCO), voltage-controlled phase shifter, or tunable bandpass filter.

The minimum capacitance ratio from 2 V to 10 V is 2.2 makes the SMV2025 series suitable for wide bandwidth VCOs and wide phase range phase shifters.

The SMV2025 is manufactured in a surface mount, industry-standard SC-79 package and an ultra-small SOD-882 package that offer very low parasitic inductance and capacitance.


  • Low series resistance and leakage current for low phase noise VCOs
  • High capacitance ratio: CT (2 V)/CT (10 V) = 2.2 minimum
  • Broad 18 V tuning range
  • Competitive cross to Toshiba 1SV280 varactor diode
  • SC-79 and ultra-small SOD-882 packages (MSL1, 260 °C per JEDEC J-STD-020)
