Description
The MAVR-000079 - 83 series of silicon hyperabrupt
junction tuning varactors is produced with ion
implantation and advanced epitaxial growth
techniques. These diodes have thermal oxide
passivation, and feature very high capacitance ratio
and quality factor. They are well suited for use from
the sub-HF through UHF frequency range. The
standard capacitance tolerance is ±10%, with tighter
tolerances available. Capacitance matching at one
or more bias voltages is also available. These
diodes are offered with standard Sn/Pb plating, as
well as 100% matte Sn plating.

Applications
This series of hyperabrupt junction tuning varactors
is suggested for usage where a large frequency
change is required with only a small change in
tuning voltage. This series is appropriate for usage
in wide band voltage controlled oscillators and
voltage controlled filters which require the largest
rate of change of capacitance with voltage. The
large change in capacitance from 1 to 8 volts makes
them very attractive for battery operated or other
systems with limited available control voltage. This
varactor series can be used in VCO’s and VTF’s
from approximately 100 KHz through the UHF
frequency band.

Handling Procedures
Please observe the following precautions to avoid
damage:
Static Sensitivity
These electronic devices are sensitive to
electrostatic discharge (ESD) and can be damaged
by static electricity. Proper ESD control techniques
should be used when handling these devices.
1. Operation of this device above any one of these parameters
may cause permanent damage.
2. Please refer to application note M538 for surface mounting
instructions.

Mounting Information
The illustration indicates the recommended
mounting
pad
configuration
for
the
SOT-23 package. Solder paste containing flux
should be screened onto the pads to a thickness of
0.005 - 0.007 inches. The plastic package is placed
in position, firmly adhering to the solder paste.
Permanent attachment is performed by a reflow
soldering procedure during which the tab
temperature does not exceed +275°C and the body
temperature does not exceed +250°C, for standard
models and +260°C for the RoHS compliant devices.
Please refer to Application Note M538 for surface
mounting instructions.
