Features
• Silicon Epitaxial Planar Diode Switches
• For electric bandswitching in radio and TV tuners
in the frequency range of 50...1000 MHz. The
dynamic forward resistance is constant and very
small over a wide range of frequency and forward
current. The reverse capacitance is also small and
largely independent of the reverse voltage.
• These diodes are also available in SOD-323 case
with the type designations BA782S and BA783S.
