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

ratings. 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).

Note1: 1 ms pulse, 1% duty cycle

Note2: Rating at mounting on a board: FR4 board. ( 40 mm

× 40 mm × 1.6 mm, Cu 4 layer )
