The photo Darlington transistor output optocoupler encapsulates infrared LED chip and photo Darlington transistor chip together to achieve the electric-optical-electrical conversion.

It can be used for power control changeover switches, for electrical insulation and impedance conversion in circuit system, Hualian provides Darlington optocouplers in different packages of SOP4, DIP4/SMD4, DIP6/SMD6 , which are characterized by high voltage withstand(V(BR)CEO≥350V), high current transfer ratio (1000%<CTR<7500%) and high insulation withstand voltage (VISO> 5000V).
