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).

Note 1: Ensure that the channel temperature does not exceed 150°C.
Note 2: VDD = 90 V, Tch = 25°C (initial), L = 24.9 mH, RG = 25 , IAR = 7 A
Note 3: Repetitive rating: pulse width limited by maximum channel temperature
This transistor is an electrostatic-sensitive device.
Please handle with caution.
