DESCRIPTION
The LH1550 is a single pole single throw (SPST), normally
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 dielec-

RMS
The coupler consists of a AlGaAs LED that is optically cou-
pled to a dielectrically isolated photodiode array which
drives two series connected high voltage MOS transistors.
The typical ON-Resistance is 37 Ω at 25 mA and is linear
up to 50 mA. There is built-in current limiting circuitry in the
detector chip, enabling it to pass FCC 68-302 and other
regulatory voltage surge requirements when over voltage
protection is provided.
