Please design the appropriate reliability upon reviewing the Weight: 0.023 g (typ.)

The following are the general derating methods that we recommend for when designing a circuit incorporating this device. V : We recommend that the worst case voltage, including surge voltage, be no greater 80tha% n of the RRM absolute maximum rating of V for a DC circuit and no greater than 50% of that of V for an AC RRM RRM circuit. V has a temperature coefficient of 0.1%/. Take this temperature account coefficient into when RRM designing a device for operation at low temperatures. I : We recommend that the wors-ctase current be no greater than 80% of the absolute maximum rating of F(AV) I and that the worst-case junction temperature, T, be kept below 120. When using this device, allow F(AV) j margins, referring to the T - I curve. a(max) F(AV) I : This rating specifies peak non-repetitive forward surge current. This only applies to an abnormal operation, FSM which seldom occurs during the lifespan of a device. T : Derate device parameters in proportion to this rating in order to ensure high reliability. j We recommend that the junction temperature (T ) of a device be kept below 120 . j 2) Thermal resistance (junction-to-ambient) varies with the mounting conditions of a device on a circuit board. An appropriate thermal resistance value should be used, considering the heat sink, circuit board design and soldering land size. 3) For other design considerations, see the Rectifiers databook or the Toshiba website. 2 2018-06-07 2.1
