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. VRRM: We recommend that the worst case voltage, including surge voltage, be no greater than 80% of the absolute maximum rating of VRRM for a DC circuit and be no greater than 50% of that of VRRM for an AC circuit. VRRM has a temperature coefficient of 0.1%/℃. 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). Carry out adequate heat design. If you can’t design a circuit with excellent heat radiation, set the margin by using an allowable Tamax-IF (AV) curve. 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 120℃ under the worst load and heat radiation conditions. Thermal resistance between junction and ambient fluctuates depending on the device’s mounting condition. When using a device, design a circuit board and a soldering land size to match the appropriate thermal resistance value.
