Datasheet
Datasheet Summary
Powered by GS/AI

The LDA111 is a unidirectional-input optocoupler with a Darlington-transistor output, designed for signal isolation in telecom switching, modem circuits, and current sensing applications. It is available in a 6-pin DIP package with dimensions of 8.382 mm length, 7.620 mm width, and 3.302 mm height, or in a surface-mount variant. The device supports a maximum input control current of 100 mA, an isolation voltage of 3750 V rms, and a current transfer ratio ranging from 300% to 30,000%. It operates from -40°C to +85°C and meets UL, CSA, and IEC 60950-1 safety certifications. The part has a saturation voltage of 1 V, a turn-on time of 8 µs, and a turn-off time of 345 µs under specified conditions.
