Pd Topr Tstg Limits 6.0 470(*1) -30 ~ +85(*2) -55 ~ +125 Unit V mW ℃ ℃ Reduced by 4.7 mW/C at 25C or higher, when mounted on a 70mm×70mm×1.6mm PCB board. Topr=70℃ ~ 85℃ is the range for performing basic operations and does not guarantee characteristics or rated output. Moreover, TSD (Thermal Shutdown) may become operable if input signals occurring in this range are excessive. 500 Power dissipation Pd[mW] 400 300 200 100 0 0 50 100 150 Temperature Ta[℃] Fig.1 Ta-Pd (when mounted on a PCB board) www.rohm.com © 2010 ROHM Co., Ltd.
