Description
The AUIRF7669L2TR(1) combines the latest Automotive HEXFET® Power MOSFET Silicon technology with the advanced DirectFETTM
packaging to achieve the lowest on-state resistance in a package that has the footprint of a DPak (TO-252AA) and only 0.7 mm profile. 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 is designed for applications where efficiency and power density are essential. The advanced DirectFET
packaging platform coupled with the latest silicon technology allows the AUIRF7669L2TR(1) to offer substantial system level savings and
performance improvement specifically in motor drive, high frequency DC-DC and other heavy load applications on ICE, HEV and EV platforms. This MOSFET utilizes the latest processing techniques to achieve low on-resistance and low Qg per silicon area. Additional features of
this MOSFET are 175°C operating junction temperature and high repetitive peak current capability. These features combine to make this
MOSFET a highly efficient, robust and reliable device for high current automotive applications.

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 asTjmax is
not exceeded.
3. Equation below based on circuit and waveforms shown in
Figures 16a, 16b.
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. ΔT = Allowable rise in junction temperature, not to exceed
Tjmax (assumed as 25°C in Figure 15, 16).
tav = Average time in avalanche.
D = Duty cycle in avalanche = tav ·f
ZthJC(D, tav) = Transient thermal resistance, see figure 11)
Fig 17. Maximum Avalanche Energy vs. Temperature
PD (ave) = 1/2 ( 1.3·BV·Iav) = DT/ ZthJC
Iav = 2DT/ [1.3·BV·Zth]
