AUIRFR9024N

Single FETs, MOSFETs Overview

The AUIRFR9024N is an automotive-grade, single P-channel HEXFET power MOSFET manufactured by Infineon Technologies. It features a maximum drain-source voltage (Vds) of -55 V and a continuous drain current (Id) of -11 A at 25°C case temperature. The device exhibits a maximum on-resistance (Rds(on)) of 0.175 Ω at Vgs = -10 V. It operates within a junction temperature range of -55°C to +150°C and supports a pulsed drain current of -44 A. The component is available in D-Pak (TO-252AA) and I-Pak (TO-251AA) packages.

• Features dynamic dv/dt rating for robust performance during diode recovery
• Utilizes advanced planar technology for low on-resistance and fast switching

Single FETs, MOSFETs Applications

• Automotive load switching circuits
• High-side power management modules
• Cellular design applications requiring ruggedized switching

Single FETs, MOSFETs Procurement Notes

Verify the specific package variant required, as the base model covers both D-Pak (AUIRFR9024N) and I-Pak (AUIRFU9024N). Confirm that the application environment meets the specified -55°C to +150°C operating temperature range. Ensure gate drive voltages remain within the ±20 V absolute maximum rating to prevent device damage. Check for RoHS compliance requirements if applicable to the final assembly.

Single FETs, MOSFETs Selection Notes

Select this component when automotive qualification (AEC-Q101) is mandatory for the system. It is suitable for applications requiring a P-channel switch with moderate current handling (-11 A) and low on-resistance (0.175 Ω). Consider the thermal resistance characteristics and ensure adequate heat sinking for continuous operation near the 38 W power dissipation limit. Verify compatibility with the required switching frequency given the gate charge specifications.

Single FETs, MOSFETs Part Context

This part belongs to the HEXFET family of power MOSFETs from Infineon Technologies. It represents the automotive-grade extension of the IRFR9024N series, distinguished by its AEC-Q101 qualification. The 'AU' prefix indicates automotive grade status, while the suffix denotes the specific package type, such as D-Pak or I-Pak.

Single FETs, MOSFETs Replacement Considerations

Direct replacements include the non-automotive IRFR9024NTRPBF for general industrial use, provided AEC-Q101 qualification is not required. For through-hole applications, the AUIRFU9024N (I-Pak) serves as the package alternative within the same electrical specification set.
