DESCRIPTION
NEC's PS7802-1A is a low output capacitance solid state
relay containing GaAs LEDs on the light emitting side (input
side) and MOSFETs on the output side.
An ultra small ß at-lead package has been provided which
realizes a reduction in mounting area about 50% compared
with the PS72xx series.
It is suitable for high fre quen cy signal control, due to its low
C x R, low on-state resistance, and low off-state leakage
current.
