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.
