cmz12~cmz53 2006-11-09 3 handling precaution 1) the absolute maximum ratings denote the absolute maximum ratings, which are rate d values and must not be exceeded during operation, even fo r an instant. the following are the general derating methods that we recommend when you design a circuit with a device. p : we recommend that the worst case power dissipation be no greater than 50% of the absolute maximum rating of power dissipa tion. carry out adequate heat design. p rsm : we recommend that a device be used wi thin the recommended area in thefigure, p rsm -tw. t j : derate this rating when using a devi ce in order to ensure high reliability. we recommend that the device be used at a t j of below 120c. 2) thermal resistance between junction and ambient fluc tuates depending on the device?s mounting condition. when using a device, design a circuit board and a so ldering land size to match the appropriate thermal resistance value. 3) please refer to the rectifiers databook for further information.
