DESCRIPTION

The LH1056 is a single pole single throw (SPST), nor-

mally open (NO), 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 7500 VACPK.

The coupler consists of a AlGaAs LED that is optically

coupled to a dielectrically isolated photodiode array

which drives two series connected high voltage MOS

transistors. The typical ON-Resistance is 30 Ω at 25 mA

and is linear up to 50 mA. The incremental resistance

drops to less than 20 Ω beyond 50 mA while reducing

internal power dissipation at high load currents. There is

built-in current limiting circuitry in the detector chip.
