Add TR suffix to device type (e.g. UC2854ADWTR) to order quantities of 2,000 devices per reel for the DW package and 1,000 devices per reel for the Q package. THERMAL RESISTANCE PACKAGED DEVICES RESISTANCES CDIP−16 (J) PDIP−16 (N) SOP−16 (DW) PLCC−20 (Q) θJC (°C/W) 28(2) 45 27 34 θJA (°C/W) 80−120 90(3) 50−130(3) 43−75(3) (2) θJC data values stated are derived from MIL-STD-1835B which states “the baseline values shown are worst case (mean +2s) for a 60 × 60 mil microcircuit device silicon die and applicable for devices with die sizes up to 14,400 square mils. For device die sizes greater than 14,400 square mils use the following values, dual-in-line, 11 °C/W; flat pack and pin grid array, 10°C/W. (3) θJA (junction-to-ambient) applies to devices mounted to five square inch FR4 PC board with one ounce copper where noted. When resitance range is given, lower values are for five square inch aluminum PC board. Test PWB is 0.062 inches thick and typically uses 0.635 mm trace widths for power packages and 1.3 mm trace widths for non-power packages with a 100 × 100 mil probe land are at the end of each trace. |
