Absolute Maximum
The MA4ST079 through MA4ST083 series of silicon
hyperabrupt junction tuning varactors is produced
with ion implantation and advanced epitaxial growth
techniques. These diodes have thermal oxide pas-
sivation, 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 toler-
ances 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 on our RoHs compliant
equivalent devices.

Configurations
Applications
The MA4ST079 through MA4ST083 series of hy-
perabrupt junction tuning varactors is suggested for
usage where a large frequency change is required
with only a small change in tuning voltage. This se-
ries is appropriate for usage in wide band voltage-
controlled oscillators and voltage controlled filters
which require the largest rate of change of capaci-
tance with voltage. The large change in capacitance
from 1 to 8 volts makes them very attractive for bat-
tery operated or other systems with limited available
control voltage. The MA4ST079 through MA4ST083
family can be used in VCOs and VTFs from approxi-
mately 100 KHz through the UHF frequency band.

Mounting Information
The illustration indicates the recommended
mounting pad configuration for the
N
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.
SOT-23
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.
