Not production tested. THERMAL RESISTANCE PACKAGE θJA (°C/W) θJC (°C/W) N(2) 90(2) 45 DW(2) 50--100(2) 27 (2) Specified θJA (junction-to-ambient) is for devices mountied to 5-square-inch FR4 PC board with one ounce copper where noted. When resistance range is given, lower values are for 5-square-inch aluminum PC board. Test PWB is 0.062 inches thick and typically uses 0.635 mm trace width for power packages and 1.3 mm trace widths for non-power packages with a 100x100 mil probe land area at the end of each trace. |
