Phototransistor Optocoupler

The OLI110 consists of an LED and N-P-N silicon phototransistor that is electrically isolated, but optically coupled on a ceramic leadless chip carrier (LCC) surface mount package. The epoxy coating on the OLI110 allows the device to withstand normal solvent cleaning operations.

Surface mounting can be accomplished with either conductive epoxies or by reflow soldering.

Special electrical parametric selections are available upon request.


    • High current transfer ratio (CTR)—guaranteed over –55 °C to +100 °C ambient temperature range
    • 1500 VDC electrical isolation
    • High breakdown voltage, collector to emitter, base open (BVCEO), >60 V
    • Small surface mount size
