| BA782, BA783 Bandswitching Diodes SOD-123 .022 (0.55) FEATURES Silicon Epitaxial Planar Diode Switches For electronic 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. with the type designations BA782S and BA783S.
