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-tolot repeatability are critical. Linear tuning
performance is available from 3 to 8 volts.

Mounting Information
SOT-23
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.
