Skyworks Solutions 

DATA SHEET • SMV1281 SERIES VARACTORS

Electrical and Mechanical Specifications

The absolute maximum ratings of the SMV1281 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 SMV1281

varactors is illustrated in Figure 1.

The SPICE model for the SMV1281 varactor series is shown in

Figure 2 and the associated model parameters are provided in

Table 5.

Package dimensions are shown in Figures 3 and 5, and tape and

reel drawings are provided in Figures 4 and 6.

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 SMV1281 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.

Production quantities of this product are shipped in a standard

tape and reel format.

Note: 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.
