DESCRIPTION

The LH1298 is a single pole single throw (SPST), nor­mally closed (NC), solid state relay. The relay can con­trol 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
VAC

RMS

.

The coupler consists of a AlGaAs LED that is optically
coupled to a dielectrically isolated monolithic inte­grated circuit. The IC chip consists of a photodiode
array, control circuitry and high voltage DMOS transis­tors. 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 limit­ing circuitry.
