The 20µs rise and 5µs fall times are slow compared to a phototransistor optocoupler — this part is not intended for switching power supplies or high-speed data isolation. 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.

Frequently asked questions
What is the closest pin-compatible alternative to PS2933-1-V-AX?
No official pin-compatible alternate is listed in the Renesas documentation for this part. For dual-sourcing, a cross-reference search against the 4-Mini-Flat footprint, 350V output, and 400% minimum CTR would identify candidates from other manufacturers.
