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 maximum rating of power dissipation. Carry out adequate heat design. PRSM: We recommend that a device be used within the recommended area in the figure, PRSM-tw. Tj: Derate this rating when using a device in order to ensure high reliability. We recommend that the device be used at a Tj of below 120C. 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. Please refer to the Rectifiers databook for further information. 5 2004-07-01 U1ZB6.8~U1ZB390 6 2004-07-01 U1ZB6.8~U1ZB390 RESTRICTIONS ON PRODUCT USE 030619EAA * The information contained herein is subject to change without notice. * The information contained herein is presented only as a guide for the applications of our products.
