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). 1 2010-02-01 CUS06 Electrical Characteristics (Ta = 25C) Characteristics Symbol Peak forward voltage Repetitive peak reverse current Junction capacitance Typ.

There is a possibility SBD may cause thermal runaway when it is used under high temperature or high voltage. This device is VF-IRRM trade-off type, lower VF higher IRRM; therefore, thermal runaway might occur when voltage is applied. Please take forward and reverse loss into consideration during the design. The absolute maximum ratings are rated values and must not be exceeded during operation, even for an instant. The following are the general derating methods that we recommend for designing a circuit using this device. VRRM: Use this rating with reference to the above. VRRM has a temperature coefficient of 0.1%/C. Take this temperature coefficient into account designing a device at low temperature. IF(AV): We recommend that the worst case current be no greater than 80% of the absolute maximum rating of IF(AV) and Tj be below 120C. When using this device, take the margin into consideration by using an allowable Tamax-IF(AV) curve. IFSM: This rating specifies the non-repetitive peak current. This is only applied for an abnormal operation, which seldom occurs during the lifespan of the device. Tj: Derate this rating when using a device in order to ensure high reliability. We recommend that the device be used at Tj of below 120C. Thermal resistance between junction and ambient fluctuates depending on the device's mounting condition. When using a device, please design a circuit board and a soldering land size to match the appropriate thermal resistance value.
