Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, as the part is available in tape and reel, cut tape, and Digi-Reel formats. Confirm RoHS compliance status and moisture sensitivity level (MSL 1) requirements against your assembly process specifications. Ensure the selected variant matches the required lead time constraints, as standard delivery periods may extend significantly depending on production schedules.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single channel with base-controlled output is required for moderate-speed switching applications. The 8-SOIC package suits space-constrained surface-mount designs. Consider the 2500 Vrms isolation rating for safety-critical interfaces. Evaluate the 20% minimum CTR to ensure adequate drive capability for downstream logic or relay loads under worst-case conditions.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the MOC256M series of transistor output optocouplers from onsemi. It is functionally related to other parts in the MOCD family but is distinct in its single-channel configuration and specific output characteristics. The part number MOC256R2M specifically denotes the reel-packaged version of the MOC256M series component.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The MOC256M is listed as a substitute option. Verify pinout compatibility and electrical parameter equivalence before replacement. Other variants within the same series may differ in packaging or specific electrical tolerances.
