RθJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of the drain pins. RθJC is guaranteed by design while RθCA is determined by the user's board design. Scale 1 : 1 on letter size paper 2. Pulse Test: Pulse Width < 300 µs, Duty Cycle < 2.0% 3. FDQ7238AS_NL is a lead free product. The FDQ7238AS_NL marking will appear on the reel label. 4. FDQ7238AS_NF40 is a lead free product. The FDQ7238AS_NF40 marking will appear on the reel label. a) 68°C/W when mounted on a 1in 2 pad of 2 oz copper (Q1). b) 52°C/W when mounted on a 1in 2 pad of 2 oz copper (Q2). c) 118°C/W when mounted on a minimum pad of 2 oz copper (Q1). d) 94°C/W when mounted on a minimum pad of 2 oz copper (Q2). |
