DESCRIPTION
The LH1298 is a single pole single throw (SPST), nor-
mally closed (NC), solid state relay. The relay can con-
trol AC or DC loads currents up to 100 mA, with a
supply voltage up to 350 V. The device is packaged in
a six pin 0.3 inch dual-in line package. This package
offers an insulation dielectric withstand of 3750
VACRMS.
The coupler consists of a AlGaAs LED that is optically
coupled to a dielectrically isolated monolithic inte-
grated circuit. The IC chip consists of a photodiode
array, control circuitry and high voltage DMOS transis-
tors. The typical ON resistance between the output
terminals is 30 Ω at 0 mA LED current. The switch
offers low off-state leakage current at LED current of
5 mA or greater. There is on board output current limit-
ing circuitry.
