Silicon epitaxial planar capacitance
diodes with very wide effective capaci-
tance 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-123 case with
the type designation BB729.
