SMV1247-SMV1255 Series: Hyperabrupt Junction Tuning
Varactors
Applications
• Low tuning voltage VCOs
• High-volume commercial systems
Features
• High capacitance ratio: C0.3V/C4.7V = 12 typical
• Packages rated MSL1, 260 °C per JEDEC J-STD-020
Description
The SMV1247-SMV1255 group of silicon hyperabrupt junction
varactor diodes is designed for use in Voltage Controlled
Oscillators (VCOs) with a low tuning voltage operation. This group
of varactors is characterized for capacitance and resistance over
temperature.
Table 1 describes the various packages and markings of the
SMV1247 to SMV1255 varactors.

Skyworks Application Note, Solder Reflow Information, document
number 200164.
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.
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.
The SMV1247-SMV1255 group of varactors are rated to Moisture
Sensitivity Level 1 (MSL1) at 260 °C. They can be used for lead or

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.
