The followings are the general derating method 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 (0.1%/℃). Please consider this temperature coefficient when you design 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). Please do the sufficient heat design. If you can’t design a circuit with excellent heat radiation, please set a 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 device’s lifespan. We recommend that a device be used Tj of below 120℃ under the worst load and heat radiation conditions. Thermal resistance between junction and ambient fluctuates depending on 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.
