Note 2: 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).

Please refer to each following absolute maximum ratings on the occasion of use and design. VRRM: In DC circuit, the voltage peaks of applied voltage must be rated less than 80 % absolute maximum ratings. In AC circuit, the voltage peaks of applied voltage must be rated less than 50 % absolute maximum ratings. And, VRRM has a temperature coefficient of 0.1 %/. Please take this coefficient into account when designing a circuit board that will be operated in a low-temperature environment. IF(AV): We recommend that the current be in less than 80 % of rating and the junction temperature (Tj) be in less than 80 % of absolute maximum rating under the worst condition. This rating is based on the premise that the device is radiating heat enough. Therefore, when enough heat radiation is not expected, please consider the margin to the permission curve of Ta(max) - IF(AV) for using the device. IFSM : This rating specifies a non-repetitive limit value. This only applies to an abnormal operation, which seldom occurs during the lifespan of a device. Tj : Derate device parameters in proportion to this rating in order to ensure high reliability. We recommend that the junction temperature (Tj) of a device be kept below 80 %. 2) Thermal resistance (junction-to-ambient) varies with the mounting conditions of the device on the circuit board. An appropriate thermal resistance value that should be used, must be considering the circuit board design and soldering land size. 3) For other design considerations, see the Toshiba website. 2 2019-03-07 2.1
