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 these devices are designed to be as robust as possible, Electrostatic Discharge (ESD) can damage them. 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. The SMV1493 and SMV1494 varactors are Class 0 Human Body Model (HBM) ESD devices.

Note 1:
Performance is guaranteed only under the conditions listed in this Table.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SMV1493 and SMV1494
varactors are provided in Table 2. Electrical specifications are
provided in Table 3. Typical capacitance values are listed in
Table 4. The typical capacitance versus reverse voltage
performance of the SMV1493 and SMV1494 varactors is
illustrated in Figure 1.
The SPICE model for the SMV1493 and SMV1494 varactors is
shown in Figure 2 and the associated model parameters are
provided in Table 5.
Package dimensions are shown in Figures 3 to 7. The SMV1493
and SMV1494 varactors are not delivered on carrier tapes.
Package and Handling Information
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 SMV1493 and SMV1494 varactors 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.
