Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'H' against the official Renesas datasheet to confirm pinout and packaging details, as standard variants may differ. Confirm RoHS compliance status through the manufacturer's latest documentation. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a surface-mount solution is required for single-channel isolation with high voltage withstand capabilities. Compare the CTR specifications and package dimensions against available alternatives like the PS2501-1-A if through-hole mounting is acceptable. Verify that the 80V output voltage rating meets the load requirements of the target application circuit.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the PS2501 family of optocouplers manufactured by Renesas Electronics. The family includes through-hole (PDIP) and surface-mount (SMD) variants with different channel counts. The PS2501-1-H-A specifically denotes the surface-mount version with a gull-wing package, distinguishing it from the standard DIP versions.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include PS2501-1-F3-A or PS2501L-1-F3-A for similar SMD configurations. Cross-reference pinouts and CTR ranges carefully before replacing, as variations exist within the PS2501 series regarding package type and electrical tolerances.
