Note 1: T = 127C Rectangular waveform ( = 180) 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). Note3: This rating specifies the non-repetitive peak current in one cycle of a 50 Hz sine wave, condition angle 180. Therefore the rating applies only to abnormal operation, which seldom occurs during the lifespan of a device.

Handling Precautions
Thermal resistance between junction and ambient fluctuates depending on the mounting condition of the device. When using the device, be sure to design the circuit board and soldering land size to match the appropriate thermal resistance value. Refer to the Rectifier databook for further information.
