Note 3: Repetitive rating: pulse width limited by maximum channel temperature

This transistor is an electrostatic-sensitive device. Please handle with caution.

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).
