MAVR-0454xx Series
Si Abrupt Tuning Varactor Diode
Rev. V8
Features
SOT-23 Single Configuration
Surface Mount Plastic Package: SOT-23
SPC Process for Superior C vs. V and Q vs. V
Repeatability
Lead free and RoHS Compliant *
Description
The MAVR-0454xx Series is a highly repeatable,
UHCVD/ion-implanted, abrupt silicon tuning varactor
in a cost effective surface mount package. This
series of varactors is designed for general purpose
tuning in the HF to UHF frequency bands. It is
efficient for wide tuning across a 0-30 V range.
These diodes are offered with 100% matte Sn
plating.
SOT-23 Common Cathode Configuration
Application
The MAVR-0454xx Series tuning varactors are
useful for tuning applications in the HF through UHF
ranges. Applications include VCO’s and voltage
tuned filters in radios, cable TV tuners and test
instruments where low cost and excellent lot to lot
repeatability are critical.

Mounting Information
SOT-23 (Case Style 287)
The illustration indicates the recommended
mounting pad configuration for the SOT-23
packages. 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.
F
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.
