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. V : We recommend that the worst case voltage, including surge voltage, be no greater than 80% of the RRM absolute maximum rating of V for a DC circuit and be no greater than 50% of that of V for RRM RRM an AC circuit. V has a temperature coefficient of 0.1%/C. Take this temperature coefficient into RRM account designing a device at low temperature. I : We recommend that the worst case current be no greater than 80% of the absolute maximum rating F(AV) of I . Carry out adequate heat design. If you cant design a circuit with excellent heat radiation, F(AV) set the margin by using an allowable Tamax-I curve. F(AV) This rating specifies the non-repetitive peak current in one cycle of a 50-Hz sine wave, condition angle 180. Therefore, this is only applied for an abnormal operation, which seldom occurs during the lifespan of the device. We recommend that a device be used at a Tj of below 120C under the worst load and heat radiation conditions. Thermal resistance between junction and ambient fluctuates depending on the devices mounting condition. When using a device, design a circuit board and a soldering land size to match the appropriate thermal resistance value. Organic silicon is used as encapsulation material for this product, which is resin seal product. Therefore, it is difficult to seal siloxane coming from silicone completely in this product. When using this product, please consider above. Please refer to the Rectifiers databook for further information. 2 2011-01-05
