Transistor, Photovoltaic Output Optoisolators Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on surplus distributors or secondary market sources rather than direct factory orders. Confirm RoHS compliance status and package integrity upon receipt, as end-of-life items may have varying storage conditions. Cross-reference substitute part numbers before finalizing procurement plans.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component only if legacy compatibility with the 6N138 pinout and electrical characteristics is required. The Darlington output offers higher gain but slower response compared to logic-output variants. Ensure the application timing constraints align with the 35 µs rise time specification. Verify that the 1.6 mA drive current is sufficient for the target circuit design.

Transistor, Photovoltaic Output Optoisolators Part Context

The 6N138 series belongs to Vishay's high-speed optocoupler family, designed for applications demanding faster switching speeds than standard transistor-output devices. The X007 suffix denotes the specific SMD-8 gull-wing package configuration. This variant integrates a photodiode input for speed and a Darlington pair for gain, balancing performance in isolated digital signal transmission.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Public confirmed substitute part number: 6N138SM. Verify pinout compatibility and electrical parameter equivalence before substitution.
