Procurement Notes

Verify the specific suffix 'V-AX' against official Renesas documentation to confirm exact tape-and-reel specifications and RoHS compliance status. Confirm that the part number matches the requested manufacturing origin, as historical data indicates transitions between NEC, CEL, and Renesas production lines. Ensure the procurement source provides valid traceability for the NRND or active status classification.

Selection Notes

Select this component when high CTR performance is required for AC input signal detection. The 4-pin SSOP form factor suits space-constrained designs. Verify that the 40 V collector-emitter voltage rating aligns with the load requirements. Consider thermal management for the 180 mW power dissipation limit in dense PCB arrangements.
