The three new automotive DirectFET2 devices
complete the 40V heavy load/motor control family
delivering exceptional power density, dual-sided
cooling and minimal parasitic inductance and
resistance for heavy load applications, including
Electric Power Steering (EPS), power supplies,
battery switches on hybrid electric vehicles and
Integrated Starter Alternators (ISA) on micro
hybrid vehicles.

• Features
• AUIRF7738L2 and AUIRF7737L2
• Exceptionally low RDS(on) and targeted for heavy
  load applications where power density and
  efficiency are desirable
• Dual sided cooling
• PCB footprint is 60 smaller than a D2Pak
• AUIRF7736M2
• Low RDS(on) and targeted for heavy load
  applications where power density and efficiency
  are desirable
• Dual sided cooling
• PCB footprint is the same size as a 5x6 PQFN or
  SO-8
• Complements the AUIRF7737, 38M2 and 39L2 devices
  with a slightly higher RDS(on) for more cost
  sensitive lower power applications

• Advantages
• The AUIRF7737L2, AUIRF7738L2 and AUIRF7736M2
  devices offer overall system level size and cost
  reductions along with superior performance and
  efficiency when compared to traditional standard
  plastic packaged components.
• Featuring a PCB footprint 60 percent smaller than
  a D2Pak, the AUIRF7738L2 and AUIRF7737L2 devices
  deliver exceptionally low on-state resistance
  while the AUIRF7736M2 features a PCB footprint
  the same size as a 5x6mm PQFN or SO-8 package
  with low RDS(on) of 2.5mOhm, making it suitable
  for more cost sensitive lower power applications.
• The AUIRF7737L2 and AUIRF7738L2 share a common
  Large Can PCB footprint with the previously
  released AUIRF7739L2 making the devices highly
  desirable components where a scalable system
  design is required.
