Note:
Using continuously under heavy loads (e.g. the application of

―
high temperature/current/voltage and the significant change in
JEITA
―
temperature, etc.) may cause this product to decrease in the
reliability significantly even if the operating conditions (i.e.

operating temperature/current/voltage, etc.) are within the

Please design the appropriate reliability upon reviewing the
Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and
individual reliability data (i.e. reliability test report and estimated failure rate, etc).
