Product details
Overview
AUIRLL024NTR from Infineon is an automotive-qualified N-channel HEXFET® Power MOSFET in SOT-223 package, rated for 55 V VDS, 3.1 A continuous drain current at TA = 25°C with 10 V gate drive, and 0.065 Ω max RDS(on). It delivers logic-level gate drive compatibility (VGS(th) = 1.0–2.0 V), 150°C junction operation, and full avalanche rating-designed for low-power DC motor control, LED lighting drivers, and body electronics in passenger vehicles.
For engineers reviewing the AUIRLL024NTR datasheet, AUIRLL024NTR pinout, AUIRLL024NTR application, or AUIRLL024NTR equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade reliability metrics, and real-world switching performance data-including 7.4 ns turn-on delay, 21 ns rise time, and 39 ns reverse recovery time under defined test conditions.
Technical Context
This MOSFET employs Infineon's advanced planar silicon process to achieve low on-resistance per die area while maintaining rugged unclamped inductive switching capability. Its dynamic dv/dt rating of 5.0 V/ns and fully rated repetitive avalanche up to Tjmax support robust operation in noisy automotive environments with fast transients.
The device integrates a monolithic body diode with 1.0 V forward voltage at 1.9 A and 39–58 ns reverse recovery time, enabling efficient synchronous rectification and freewheeling in buck converters and H-bridge motor drivers. Thermal resistance is specified as 90 °C/W (min footprint) and 50 °C/W (1-inch copper pad), directly linking PCB layout to safe operating area limits.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL10DN3LLH6 | 40 V VDS, 0.045 Ω RDS(on), SOT-23 package, lower current (2.5 A) | Limited to 12 V non-load-dump circuits; unsuitable for solenoid or motor stall conditions above 40 V | Prefer for space-constrained, low-power sensor interface; avoid where 55 V margin or 3.1 A continuous current is required |
| ON Semiconductor NTMFS4C09NT1G | 30 V VDS, 0.0095 Ω RDS(on), SO-8FL package, higher current (12 A) | Requires external gate driver for 3.3 V logic; not AEC-Q101 qualified; larger footprint | Choose only for high-efficiency, high-current 12 V bus switching where automotive qualification is secondary |
Compared with STL10DN3LLH6 and NTMFS4C09NT1G, AUIRLL024NTR uniquely balances 55 V ruggedness, logic-level drive, AEC-Q101 compliance, and SOT-223 thermal performance-making it the only option validated for under-hood BCM and start-stop solenoid use without derating or supplemental protection.

FAQ
Is AUIRLL024NTR pin-compatible with standard SOT-223 MOSFETs?
Yes-AUIRLL024NTR uses the industry-standard SOT-223 (TO-261AA) footprint with Drain-Source-Gate pinout order (D-S-G-S). The exposed drain tab aligns with JEDEC MO-178AB, enabling drop-in replacement in existing layouts designed for compatible SOT-223 devices, provided thermal and electrical ratings are verified.
What is the maximum PCB copper area needed to achieve the 50 °C/W RθJA thermal rating?
The 50 °C/W RθJA value is measured on a 1-inch square (25.4 mm × 25.4 mm) copper pad with 2 oz (70 µm) thickness, connected via ≥4 thermal vias (0.3 mm diameter) to inner ground planes. Smaller pads yield higher thermal resistance-e.g., minimum FR-4 footprint achieves 90 °C/W per datasheet note.
Does AUIRLL024NTR require a gate resistor for automotive EMI compliance?
A gate resistor (typically 10–24 Ω) is recommended to dampen ringing caused by PCB trace inductance and gate capacitance interaction. The datasheet specifies switching times with RG = 24 Ω; omitting it may exceed CISPR 25 Class 5 radiated emission limits in 12 V systems due to excessive dv/dt overshoot.
Can AUIRLL024NTR replace older IRLL024N parts in legacy designs?
Yes-AUIRLL024NTR is the automotive-qualified successor to IRLL024N, sharing identical pinout, RDS(on), and switching characteristics. Key improvements include AEC-Q101 qualification, tighter VGS(th) distribution (1.0–2.0 V), and updated RoHS/lead-free compliance-no layout or firmware changes are needed for migration.
