Description
The SMV2019-SMV2023 series are silicon hyperabrupt junction
varactor diodes. The capacitance ratio and low series resistance
of these varactors make them attractive for low phase noise
Voltage-Controlled Oscillators (VCOs) in wireless systems.
Table 1 describes the various packages and markings of the
SMV2019-SMV2023 series of varactors.

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. This device
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.

Electrical and Mechanical Specifications
The absolute maximum ratings of the SMV2019-SMV2023 series
of varactors are provided in Table 2. Electrical specifications are
provided in Table 3. The relationship between capacitance and
reverse voltage is illustrated in Figures 1, 2, and 3. Table 4
summarizes the capacitance of the SMV2019-SMV2023 series.
The SPICE model for the SMV2019-SMV2023 varactor series is
shown in Figure 4 and the associated model parameters are
provided in Table 5.
Package dimensions are provided in Figures 5 to 11 (odd
numbers), and tape and reel drawings are provided in Figures 6 to

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.
