Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., -000E, -500E) to confirm package type and insulation rating. Confirm RoHS compliance status as indicated in official documentation. Ensure the selected variant matches the required operating temperature range and isolation voltage specifications for the target application environment.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high current drive capability is required at moderate speeds. The photodarlington output offers higher gain than standard phototransistors but slower switching. Consider the integrated base terminal for optimizing turn-off time in demanding pulse applications compared to variants without this feature.

Transistor, Photovoltaic Output Optoisolators Part Context

The 6N139 belongs to the 6N13x series of high-speed optocouplers manufactured by Broadcom Limited. This series is designed for robust digital isolation in noisy environments. The 6N139 specifically utilizes a photodarlington output stage, distinguishing it from open-collector or photodiode-based counterparts in the same family.
