The AUIRF7640S2TR/TR1 combines the latest Automotive HEXFET[®] Power MOSFET Silicon technology with the advanced DirectFET[®] packaging platform to produce a best in class part for Automotive Class D audio amplifier applications. The DirectFET[®] package is compatible with existing layout geometries used in power applications, PCB assembly equipment and vapor phase, infra-red or convection soldering techniques, when application note AN-1035 is followed regarding the manufacturing methods and processes. The DirectFET[®] package allows dual sided cooling to maximize thermal transfer in automotive power systems. 

This HEXFET[®] Power MOSFET optimizes gate charge, body diode reverse recovery and internal gate resistance to improve key Class D audio amplifier performance factors such as efficiency, THD and EMI. Moreover the DirectFET[®] packaging platform offers low parasitic inductance and resistance when compared to conventional wire bonded SOIC packages which improves EMI performance by reducing the voltage ringing that accompanies current transients. 

These features combine to make this MOSFET a highly desirable component in Automotive Class D audio amplifier and other high speed switching systems.

## **Absolute Maximum Ratings** 

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.   These are stress ratings only; and functional operation of the device at these or any other condition beyond those indicated in the specifications is not implied. Exposure to absolutemaximum-rated conditions for extended periods may affect device reliability. The thermal resistance and power dissipation ratings are measured under 

board mounted and still air conditions. Ambient temperature (TA) is 25°C, unless otherwise specified.

## **Notes on Repetitive Avalanche Curves , Figures 16, 17:** 

**(For further info, see AN-1005 at www.infineon.com)** 

1. Avalanche failures assumption: 

   - Purely a thermal phenomenon and failure occurs at a temperature far in 

   - excess of Tjmax. This is validated for every part type. 

2. Safe operation in Avalanche is allowed as long as Tjmax is not exceeded. 

3.  Equation below based on circuit and waveforms shown in Figures 18a, 18b. 

4.  PD (ave) = Average power dissipation per single avalanche pulse. 

5.  BV = Rated breakdown voltage (1.3 factor accounts for voltage increase during avalanche). 

6.  Iav = Allowable avalanche current. 

7. T = Allowable rise in junction temperature, not to exceed Tjmax (assumed as 25°C in Figure 16, 17). 

   - tav = Average time in avalanche. 

   - D = Duty cycle in avalanche =  tav ·f 

   - ZthJC(D, tav) = Transient thermal resistance, see Figures 15) 

## **PD (ave) = 1/2 ( 1.3·BV·Iav) =**  **T/ ZthJC Iav = 2**  **T/ [1.3·BV·Zth] EAS (AR) = PD (ave)·tav**
