Ensure compliance with RoHS directives if required, noting specific environmental classifications. Validate datasheet revisions for accurate electrical characteristics before integration into new designs.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component for applications demanding high-speed data transfer with robust isolation. The wide-body package facilitates easier PCB handling and soldering. Consider the 5000Vrms isolation rating for safety-critical circuits. Evaluate the TTL compatibility against logic levels in the target system to ensure proper interfacing without additional level shifting.

Transistor, Photovoltaic Output Optoisolators Part Context

Part of the CNW13x series from onsemi, designed for fast-switching applications. The series includes variants like CNW136 and CNW4502, sharing similar electrical performance but differing in base configuration. The CNW135 specifically features a connected base terminal for the output transistor, distinguishing it from non-connected base alternatives within the same family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include CNW136 and CNW4502. Note that CNW4502 has a non-connected base, offering increased ESD protection compared to the CNW135's connected base design. Verify pinout compatibility and electrical parameter alignment when substituting.
