1458 Optocoupler Datasheet Upd -

Exceeding the maximum limitations designated by the manufacturer can lead to permanent silicon degradation. Circuit designers should look for verified parts on platforms like Mouser Electronics or Farnell to cross-verify the specific breakdown voltages matching their region's electrical compliance codes.
