It is sized for relay-coil drive, solenoid valves, AC zero-cross detection, and status feedback where the load's own response time dominates. The high CTR means the input LED can be driven at 1mA or less, which keeps the forward current well under the 50mA absolute maximum and reduces LED aging drift over the part's service life. ## Lifecycle and sourcing posture The PS2933-1-V-AX carries an Active lifecycle status and is ROHS3 compliant. For current pricing and availability, submit an RFQ — the independent distribution network sources this part to order, with confirmed lead time and price returned at quote time. No official second-source or pin-compatible alternate is listed in the Renesas documentation; if dual-sourcing is required, a cross-reference search against the 4-Mini-Flat footprint and 350V / 400% CTR minimum would be needed.","metaTitle":"PS2933-1-V-AX Darlington Optocoupler, 2500Vrms, 350V Output","metaDescription":"PS2933-1-V-AX Darlington optocoupler from Renesas. 1-channel, 2500Vrms isolation, 350V output, 400-4500% CTR.
