ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the permanent
damages and may degrade the life time and safety for both device and system using the device in the field. The
functional operation at or over these absolute maximum ratings is not assured.

RECOMMENDED OPERATING RATINGS
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating ratings. The semiconductor devices cannot operate normally over the recommended
operating ratings, even if when they are used over such ratings by momentary electronic noise or surge. And the
semiconductor devices may receive serious damage when they continue to operate over the recommended
operating ratings.
