The OLI149 is designed especially for high-reliability applications that require optical isolation in radiation environments such as gamma , neutron, and proton radiation with high CTR and low saturation V_CE.

Each optocoupler consists of an LED and N-P-N silicon photo-transistor that is electrically isolated, but optically coupled on a ceramic Leadless Chip Carrier (LCC) surface mount package. The epoxy coating on the OLI149 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.
