HCPL0730

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL-0730 is a dual-channel low input current, high gain split darlington optocoupler. It consists of two GaAsP light-emitting diodes optically coupled to integrated high-gain photodetectors housed in an 8-pin SOIC package. The split darlington configuration separates the input photodiode and first stage gain from the output transistor, enabling lower output saturation voltage and higher speed operation compared to conventional darlington phototransistor optocouplers.
