Description
Specifically designed for Automotive applications, this
Cellular design of HEXFET® Power MOSFETs utilizes
the latest processing techniques to achieve low onresistance 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.
Only products certified as military grade by the Defense Logistics Agency (DLA) of the US Department of Defense,
are designed and manufactured to meet DLA military specifications required by certain military, aerospace or other
applications. Buyers acknowledge and agree that any use of IR products not certified by DLA as military-grade, in
applications requiring military grade products, is solely at the Buyer’s own 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.
