FEATURES
Silicon epitaxial planar capacitance diodes with
♦
very wide effective capacitance variation
for tuning the whole range of VHF CTV tuners.
♦
These diodes are available as singles or as matched sets of
two or more units according to
the tracking condition described in the table
of characteristics.
♦
This diode is also available in SOD-323 case
with the type designation BB729S.
