Board size : 50 mm 50 mm Land pattern size : 2 mm 2 mm Board thickness : 0.64 mm 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).

The following are the general derating methods that we recommend when you design a circuit with a device. P : We recommend that the worst case power dissipation be no greater than 50% of the absolute maximum rating of power dissipation. Carry out adequate heat design. P : We recommend that a device be used within the recommended area in the figure, RSM P -tw. RSM T : Derate this rating when using a device in order to ensure high reliability. j We recommend that the device be used at a T of below 120C. j 2) Thermal resistance between junction and ambient fluctuates depending on the devices mounting condition. When using a device, design a circuit board and a land pattern size to match the appropriate thermal resistance value. 3) Please refer to the Rectifiers databook for further information. 2 2015-05-15
