Silicon epitaxial planar capacitance diodes with very wide
effective capacitance variation for tuning
the VHF range 41 … 170 MHz in hyper-
band television 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 BB731S.
