Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'TSR2VM' against current manufacturer documentation to confirm availability status, as this variant may be obsolete or subject to change. Ensure the surface-mount tape-and-reel format matches your pick-and-place equipment specifications. Cross-reference the pinout diagram with your PCB layout to confirm compatibility with existing designs.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation with high-speed performance is required in a compact surface-mount form factor. Consider the 5000 Vrms isolation rating for applications requiring robust separation between high-voltage and low-voltage domains. Verify that the 1 MBps data rate meets the system's timing requirements and that the operating temperature range aligns with environmental conditions.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to onsemi's HCPL-2531 family of high-speed optocouplers. The family includes variants such as HCPL-2531S and HCPL-2531SV, which share similar electrical characteristics but differ in packaging and reel configurations. These devices are designed to replace pulse transformers in various digital isolation applications.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include HCPL-2531S and HCPL-2531SV from onsemi, provided the packaging difference (through-hole vs. surface-mount) is acceptable. Other compatible parts in the same functional category include HCPL-2530 and HCPL-2503, though pinouts and specific electrical parameters should be verified against the original design requirements.
