Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix '300' confirms the black package variant as documented in official Fairchild specifications. Ensure compatibility with existing PCB footprints for 6-pin DIP configurations. Cross-reference manufacturer part numbers to confirm equivalence with legacy Motorola or ISOCOM components if sourcing from alternative distributors. Confirm RoHS compliance status based on the specific production batch documentation provided by the supplier.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and low noise are critical requirements. The absence of a base lead makes it suitable for applications requiring minimal capacitive coupling between input and output circuits. Consider the 70V minimum breakdown voltage for driving higher voltage loads directly. Verify that the required current transfer ratio groups meet the specific gain requirements of the target application circuit design.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the MOC810X series of 6-pin DIP optocouplers designed primarily for power supply applications. It shares architectural similarities with the CNY17 family but features optimized characteristics for industrial environments. The series is recognized by UL and VDE standards, ensuring safety compliance for global deployment in regulated electronic equipment markets.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Equivalent parts include the MOC8107 and variants from manufacturers such as Motorola and ISOCOM. Verify pinout compatibility and electrical parameter tolerances before substitution. The MOC8107W may serve as a white package alternative if color coding is not restricted.
