Discharge (HID) lighting, and DC-DC applications
used in electric and hybrid electric vehicles.
Automotive HOME PAGE

• Features
• Advanced process technology
• Optimized for Automotive Motor Drive, DC-DC and
  other heavy load applications
• Exceptionally small footprint and low profile
• High power density
• Low parasitic parameters
• Dual sided cooling
• Repetitive avalanche capability for robustness
  and reliability
• Lead free, RoHS compliant
• The AUIRF7648M2 features a PCB footprint 54
  smaller than a DPak while the AUIRF7669L2
  features a PCB footprint 60 smaller than a
  D2Pak. With package current ratings of 179A and
  375A respectively for each device, the DirectFET
  package places no constraint on current
  capability of the silicon and moreover the
  maximum package current ratings far exceed the
  limits of traditional DPak and D2Pak packages.

• Advantages
• The AUIRF7648M2 and AUIRF7669L2 offer low RDS(on)
  and are targeted for switching applications where
  low gate charge is important to keep switching
  losses to a minimum. The DirectFET package has
  very low parasitic inductance giving the part
  excellent high frequency switching performance
  with reduced waveform ringing which in turn helps
  limit EMI and filter size.
• Automotive DirectFET 2 packaging concept has
  three fundamental values
• Minimal thermal impedance with the dual sided
  cooling option
• Minimal parasitic package inductance through the
  elimination of wire bonds
• Very low package resistance to minimize
  conduction losses
• Equipped with these fundamental values the AU DF
  products offer
• Exceptional power density
• Outstanding efficiency
• System level cost savings
