The coupler consists of an AlGaAs LED that is optically coupled to a dielectrically isolated photodiode array which drives two series connected high voltage MOS transistors. The typical ON-Resistances (see table) of 20 or 40 ohms at 25mA are linear up to 50 mA; the incremental resistance drops to less than 20 to 40 ohms beyond 50 mA while reducing internal power dissipation at high load currents.
