Note: Using continuously under heavy loads (e.g. the application of high
temperature/current/voltage and the significant change in
temperature, etc.) may cause this product to decrease in the
reliability significantly even if the operating conditions (i.e.
JEDEC
JEITA
operating temperature/current/voltage, etc.) are within the
absolute maximum ratings.
Please design the appropriate reliability upon reviewing the
TOSHIBA

Weight: 9.75 g (typ.)
Toshiba Semiconductor Reliability Handbook (“Handling
Precautions”/Derating Concept and Methods) and individual reliability data (i.e. reliability test report and
estimated failure rate, etc).
