Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (R1M) against official datasheets to confirm the tape-and-reel packaging configuration. Ensure compatibility with SOIC-Narrow-8 footprint requirements during PCB layout. Cross-reference manufacturer documentation for updated insulation system certifications and safety ratings before finalizing procurement specifications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when base-controlled switching speed is critical for AC load applications. The integrated base allows for faster turn-off times compared to standard phototransistors. Verify that the required isolation voltage meets or exceeds 2500 Vrms for the target application environment. Confirm that the 30 V collector-emitter voltage rating accommodates the downstream circuit requirements.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the MOC256 series of transistor output optocouplers. It shares functional similarities with the MOC256R2M but differs in packaging and reel specifications. The series is designed for general-purpose isolation where moderate switching speeds and high isolation voltages are required.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The MOC256R2M is a related variant within the same family. Verify if the packaging difference (reel vs. cut tape/tray) impacts assembly processes. Direct pin-compatible substitutes require separate verification against official cross-reference lists.
