SMV1130 Series: Hyperabrupt Junction Tuning Varactors
Applications
• High-volume, low-cost systems
• Wideband VCOs
Features
• High tuning ratio
• Low series resistance
• Packages rated MSL1, 260 °C per JEDEC J-STD-020
Description
The SMV1130 series of surface mount hyperabrupt junction
varactor diodes are designed for very high capacitance tuning
ratios with a low series resistance, which makes these devices
especially attractive for wideband Voltage-Controlled Oscillator
(VCO) applications.
Table 1 describes the packages and markings of the SMV1130
varactors.

Forward current IF 20 mA
Power dissipation PDIS 250 mW
Operating temperature TOP –55 +125 °C
Storage temperature TSTG –55 +150 °C
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.

Electrical and Mechanical Specifications
The absolute maximum ratings of the SMV1130 varactors are
provided in Table 2. Electrical specifications are provided in
Table 3. Typical capacitance values are listed in Table 4. Typical
capacitance vs voltage performance for the SMV1130 varactors is
illustrated in Figure 1.
The SPICE model for the SMV1130 varactor series is shown in
Figure 2 and the associated model parameters are provided in
Table 5.
Package dimensions are shown in Figures 3, 5, and 7, and tape
and reel drawings are provided in Figures 4, 6, and 8.
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 SMV1130 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.
