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 = 25 V, Tch = 25°C (initial), L = 2.2 mH, RG = 25 Ω, IAR = 5 A
Note 3: Repetitive rating: pulse width limited by maximum channel temperature
This transistor is an electrostatic-sensitive device. Handle with care.
