RJA 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. RJC is guaranteed by design while R CA is determined by the user's board design. a) RJA is 125?C/W (steady state) when mounted on a 1 inch? copper pad on FR-4. b) RJA is 208?C/W (steady state) when mounted on a minimum copper pad on FR-4. 2. Pulse Test: Pulse Width < 300?s, Duty Cycle < 2.0% 3. The diode connected between the gate and source serves only as protection against ESD. No gate overvoltage rating is implied.
