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.
