Procurement Notes

Verify component authenticity through official Renesas channels or authorized distributors due to limited availability status. Confirm RoHS compliance details and specific safety certifications such as UL, CSA, BSI, or VDE approvals required for the target application. Check for obsolescence notices or recommended replacement parts if integrating into new designs. Ensure storage conditions meet semiconductor handling standards to maintain device integrity prior to assembly.

Selection Notes

Select this component when a single-channel isolation solution with high voltage withstand capability is required in a small footprint. The SSOP-4 package suits space-constrained PCB layouts compared to larger DIP options. Consider the 80 V collector-emitter voltage rating against load requirements. Evaluate the 5 mA forward current drive needs against available microcontroller GPIO capabilities. Verify that the operating temperature range meets environmental specifications.

Part Context

This part belongs to the PS2801 series of high-isolation voltage photocouplers from Renesas Electronics. The series utilizes GaAs light emitting diodes paired with NPN silicon phototransistors. The PS2801-1 variant specifically denotes a single-channel configuration within the family, which also includes four-channel versions like the PS2801-4. These devices are engineered for reliable signal transmission across isolated boundaries in industrial and commercial electronics.
