DESCRIPTION
The PS7801E-1A is a low output capacitance solid state relay containing a GaAs LED on the light emitting side
(input side) and MOS FETs on the output side.
An ultra small flat-lead package has been provided which realizes a reduction in mounting area of about 50%
compared with the PS72xx series.
It is suitable for high-frequency signal control, due to its low C
×
R, low output capacitance, and low off-state
leakage current.
FEATURES
