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 dissipation. Carry out adequate heat design. PRSM : We recommend that a device be used within the recommended area in thefigure, 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 120°C. 2) 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. 3) 3 2006-11-09 CMZ12~CMZ53 Ta max – P 160 140 Device mounted on a ceramic board: board size: 50 mm × 50 mm Soldering land: 2.0 mm × 2.0 mm board thickness: 0.64 t PRSM – tW 1000 (reference value) PRSM tW Ta = 25°C Rectangular pulse Maximum allowable temperature Ta max (°C) 120 100 80 60 40 20 0 0 0.4 0.8 1.2 1.6 2 2.4 Non-repetitive peak reverse Power dissipation PRSM (W) Recommended 100 10 0.1 1 10 Power dissipation P (W) Pulse width tW (ms) αT – V Z 25 CMZ12~CMZ27 (typ.) 50 CMZ30~CMZ53 αT – V Z (typ.)
