Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific datasheet revision and compliance certifications such as UL or IEC before procurement. Confirm that the PDIP-8 through-hole package aligns with your PCB layout requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the manufacturer part number to avoid confusion with similar series components like the 6N139.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when moderate speed isolation is required alongside high output drive capability. The photodarlington output offers higher gain compared to standard transistor outputs but exhibits slower switching speeds than open-collector variants. Consider thermal management due to the specified power dissipation limits. Evaluate if the 100 kb/s data rate suffices for your application's timing constraints.

Transistor, Photovoltaic Output Optoisolators Part Context

This component belongs to the 6N13x series of high-speed optocouplers from Broadcom Limited. It shares architectural similarities with the 6N137 and 6N139 but differs in output stage design. The series is designed for general-purpose digital isolation where cost-effective performance is prioritized over ultra-high speed or specialized logic compatibility.
