CMH04 2013-11-01 2 marking abbreviation code part no. h4 CMH04 standard soldering pad handling precaution 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 genera l derating methods that we recommend when you design a circuit with a device. v rrm : we recommend that the worst case voltage, including surge voltage, be no greater than 80% of the absolute maximum rating of v rrm for a dc circuit and be no greater than 50% of that of v rrm for an ac circuit. v rrm has a temperature coefficient of 0.1%/ . take this temperature coefficient into account designing a device at low temperature. i f(av) : we recommend that the worst case current be no gr eater than 80% of the abso lute maximum rating of i f(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-i f (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 fluctuat es 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. please refer to the rectifiers databook for further information. 3.0 1.4 2.1 unit: mm 1.4
