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. The
SMV1493-079LF and SMV1494-079LF varactors are Class 0 Human Body Model (HBM) ESD devices.

Electrical and Mechanical Specifications
The absolute maximum ratings of the SMV1493-079LF and
SMV1494-079LF varactors are provided in Table 2. Electrical
specifications are provided in Table 3. Typical capacitance values
are listed in Table 4. Typical capacitance vs reverse voltage
performance for the SMV1494-079LF and SMV1494-079LF
varactors is illustrated in Figure 1.
The SPICE model for the SMV1493-079LF and SMV1494-079LF
varactors is shown in Figure 2 and the associated model
parameters are provided in Table 5.
Package dimensions are shown in Figure 3, and tape and reel
dimensions are provided in Figure 4.
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 SMV1493-079LF and SMV1494-079LF 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.
