BA783

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.
