Description
M/A-COM’s MA4ST400 series are ion-implanted,
hyperabrupt junction, silicon tuning varactors in
the SOT-23 surface mount package. These thermal oxide passivated diodes feature high capacitance ratio and quality factor. They are well suited
for octave bandwidth tuning in the HF to UHF frequency bands. 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 with 100%
matte Sn plating on our RoHS compliant devices.
Applications
The MA4ST400 series tuning varactors are useful
for octave bandwidth tuning applications in the HF
through UHF ranges. Applications include VCOs
and voltage tuned filters in radios, cable TV tuners and test instruments where low cost and excellent lot-to-lot repeatability are critical. Linear
tuning performance is available from 3 to 8 volts.

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.
SOT-23
.030 min.

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.
