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 VAC
PK
.
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
and is linear up to 50 mA. The incremental resistance
drops to less than 20
beyond 50 mA while reducing
internal power dissipation at high load currents. There is
built-in current limiting circuitry in the detector chip.
