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).
Note 1: Mounted on FR4 board
(25.4 mm × 25.4 mm × 1.6 t, Cu pad: 645 mm²)
Note 2: The pulse width limited by maximum channel temperature.

Handling Precaution
When handling individual devices (which are not yet mounted on a circuit board), be sure that the environment is
protected against electrostatic electricity. Operators should wear anti-static clothing, and containers and other
objects that come into direct contact with devices should be made of anti-static materials.
The Channel-to-Ambient thermal resistance R_{th (ch-a)} and the drain power dissipation P_D vary according to the
board material, board area, board thickness and pad area, and are also affected by the environment in which the
product is used. When using this device, please take heat dissipation fully into account
