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-123 case with
the type designation BB729.
