Description
The SMV1265 series of hyperabrupt junction tuning varactors are
designed for very high capacitance tuning ratios with low series
resistance, which makes these devices especially attractive for
wideband Voltage Controlled Oscillator (VCO) applications.
The packaging options are defined in Table 1. The absolute
maximum ratings of the SMV1265 varactor series are provided in
Table 2. Electrical specifications are specified in Table 3. Figure 1
shows the typical performance of capacitance versus voltage. The
SPICE model for the SMV1265 series is shown in Figure 2 and the
associated model parameters are provided in Table 4. The
relationship between voltage and capacitance for the SMV1265
series is shown in Table 5.

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. These
devices must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the
human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all
times.

Package and Handling Information
The package dimensions and tape and reel dimensions for the
SOD-323 are shown in Figures 3 and 4, respectively The package
dimensions and tape and reel dimensions for the SOD-882 are
shown in Figures 5 and 6, respectively.
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
The SMV1265 series are rated to Moisture Sensitivity Level 1
(MSL1) at 260 C. They can be used for lead or lead-free
soldering. For additional information, refer to the Skyworks
Application Note, Solder Reflow Information, document number
200164.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.
