B1 FDB3632 / FDP3632 / FDI3632 Test Circuits and Waveforms (T –T ) JM A P D M = ----------------------------R θ JA (EQ. 1) In using surface mount devices such as the TO-263 package, the environment in which it is applied will have a significant influence on the part’s current and maximum power dissipation ratings. Precise determination of P DM is complex and influenced by many factors: 1. Mounting pad area onto which the device is attached and whether there is copper on one side or both sides of the board. 80 RθJA = 26.51+ 19.84/(0.262+Area) EQ.2 RθJA = 26.51+ 128/(1.69+Area) EQ.3 60 RθJA (o C/W) The maximum rated junction temperature, TJM , and the thermal resistance of the heat dissipating path determines the maximum allowable device power dissipation, PDM , in an application. Therefore the application’s ambient temperature, TA (oC), and thermal resistance RθJA (oC/W) must be reviewed to ensure that TJM is never exceeded. Equation 1 mathematically represents the relationship and serves as the basis for establishing the rating of the part. 40 20 0.1 1 10 (0.645) (6.45) AREA, TOP COPPER AREA in2 (cm2 ) (64.5) Figure 21. Thermal Resistance vs Mounting Pad Area 2. The number of copper layers and the thickness of the board. 3. The use of external heat sinks. 4. The use of thermal vias. 5. Air flow and board orientation. 6. For non steady state applications, the pulse width, the duty cycle and the transient thermal response of the part, the board and the environment they are in. Fairchild provides thermal information to assist the designer’s preliminary application evaluation. Figure 21 defines the RθJA for the device as a function of the top copper (component side) area. This is for a horizontally positioned FR-4 board with 1oz copper after 1000 seconds of steady state power with no air flow. This graph provides the necessary information for calculation of the steady state junction temperature or power dissipation. Pulse applications can be evaluated using the Fairchild device Spice thermal model or manually utilizing the normalized maximum transient thermal impedance curve. Thermal resistances corresponding to other copper areas can be obtained from Figure 21 or by calculation using Equation 2 or 3. Equation 2 is used for copper area defined in inches square and equation 3 is for area in centimeters square. The area, in square inches or square centimeters is the top copper area including the gate and source pads.
