Description
Specifically designed for Automotive applications, this
cellular design of HEXFET® Power MOSFETs utilizes
the latest processing techniques to achieve low on-resis-
tance per silicon area. This benefit combined with the fast
switching speed and ruggedized device design that
HEXFET power MOSFETs are well known for, provides
the designer with an extremely efficient and reliable
device for use in Automotive and a wide variety of other
applications.

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
absolute-maximum-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.

IMPORTANT NOTICE
Unless specifically designated for the automotive market, International Rectifier Corporation and its subsidiaries (IR) reserve the right
to make corrections, modifications, enhancements, improvements, and other changes to its products and services at any time and to
discontinue any product or services without notice. Part numbers designated with the “AU” prefix follow automotive industry and / or
customer specific requirements with regards to product discontinuance and process change notification. All products are sold subject
to IR’s terms and conditions of sale supplied at the time of order acknowledgment.
IR warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with IR’s standard
warranty. Testing and other quality control techniques are used to the extent IR deems necessary to support this warranty. Except
where mandated by government requirements, testing of all parameters of each product is not necessarily performed.
IR assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using IR components. To minimize the risks with customer products and applications, customers should provide adequate
design and operating safeguards.
Reproduction of IR information in IR data books or data sheets is permissible only if reproduction is without alteration and is
accompanied by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alterations is an
unfair and deceptive business practice. IR is not responsible or liable for such altered documentation. Information of third parties may
be subject to additional restrictions.
Resale of IR products or serviced with statements different from or beyond the parameters stated by IR for that product or service voids
all express and any implied warranties for the associated IR product or service and is an unfair and deceptive business practice. IR
is not responsible or liable for any such statements.
IR products are not designed, intended, or authorized for use as components in systems intended for surgical implant into the body,
or in other applications intended to support or sustain life, or in any other application in which the failure of the IR product could create
a situation where personal injury or death may occur. Should Buyer purchase or use IR products for any such unintended or
unauthorized application, Buyer shall indemnify and hold International Rectifier and its officers, employees, subsidiaries, affiliates, and
distributors harmless against all claims, costs, damages, and expenses, and reasonable attorney fees arising out of, directly or
indirectly, any claim of personal injury or death associated with such unintended or unauthorized use, even if such claim alleges that
IR was negligent regarding the design or manufacture of the product.
IR products are neither designed nor intended for use in military/aerospace applications or environments unless the IR products are
specifically designated by IR as military-grade or “enhanced plastic.” Only products designated by IR as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of IR products which IR has not designated as military-grade is solely
at the Buyer’s risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with
such use.
IR products are neither designed nor intended for use in automotive applications or environments unless the specific IR products are
designated by IR as compliant with ISO/TS 16949 requirements and bear a part number including the designation “AU”. Buyers
acknowledge and agree that, if they use any non-designated products in automotive applications, IR will not be responsible for any
failure to meet such requirements.
