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).

Abbreviation Code Part No. S8 CMS08 Standard Soldering Pad Handling Precaution Schottky barrier diodes have reverse current characteristic compared to the other diodes. There is a possibility SBD may cause th ermal runaway when it is used under high temperature or high voltage. This device is V F-IRRM trade-off type, lower V F higher I RRM; therefore, thermal r unaway might occur when voltage is applied. Please take forward and reverse loss into consideration during design. The absolute maximum ratings denote the absolute maximu m ratings, which are rated values and must not be exceeded during operation, even for an instant. The following are the general derating methods that we recommend when you design a circuit with a device. VRRM: Use this rating with reference to the above. V RRM 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 I F(AV) and T j be below 100°C. 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 curren t. 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 a Tj of below 100°C. Thermal resistance between junction and ambient fluctuat es depending on the device’s mounting condition. When using a device, please design a circuit board and a solderin g land size to match the appropriate thermal resistance value. Please refer to the Rectifiers databook for further information. 3.0 1.4 2.1 Unit: mm 1.4
