Weight: 1.5 g (typ.)
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).
Thermal Characteristics
Characteristic Thermal resistance, channel to case Symbol Rth (ch-c) Max 1.56 Unit C/W 2
Note 1: Ensure that the channel temperature does not exceed 150C. Note 2: VDD = 90 V, Tch = 25C (initial), L = 16.1 mH, RG = 25 , IAR = 6.5 A Note 3: Repetitive rating: pulse width limited by maximum channel temperature. This transistor is an electrostatic-sensitive device. Handle with care.
