Product details

Overview

AUIRLR3410 from Infineon Technologies is an automotive-grade N-channel DPAK-packaged HEXFET® Power MOSFET with 100 V V(BR)DSS, 105 mΩ RDS(on) max at VGS = 10 V, 17 A continuous drain current at TC = 25°C, and full avalanche rating up to TJ = 175°C - deployed in high-reliability engine control, powertrain solenoid drivers, and DC-DC converter high-side switches.

For engineers reviewing the AUIRLR3410 datasheet, AUIRLR3410 pinout, AUIRLR3410 application, or AUIRLR3410 equivalent, key selection criteria include its logic-level gate drive (VGS(th) = 1.0–2.0 V), low thermal resistance (RθJC = 1.9 °C/W), body diode reverse recovery performance (trr = 140–210 ns), and automotive qualification per AEC-Q101 standards.

Technical Context

This N-channel enhancement-mode MOSFET uses stripe planar technology to achieve low on-resistance per die area while maintaining rugged unclamped inductive switching capability. Its dynamic dV/dt rating and fully rated repetitive avalanche operation (up to TJmax) support robust operation in automotive load dump and inductive flyback conditions.

The device integrates a fast, low-Qrr body diode (Qrr = 740–1100 nC) with controlled reverse recovery characteristics, enabling efficient synchronous rectification and freewheeling in buck converters and motor H-bridge legs without external snubbers.

Key Specifications

Parameter	Value and Actual Design Meaning
V(BR)DSS	100 V - Withstands 100 V drain-source blocking voltage before avalanche onset; suitable for 42 V automotive systems and 24 V industrial rails.
RDS(on) max	105 mΩ @ VGS = 10 V, TJ = 25°C - Enables <1.8 W conduction loss at 13 A, critical for thermally constrained under-hood modules.
ID @ TC = 25°C	17 A - Sustains 17 A continuous drain current with PCB-mounted heatsinking; supports high-current solenoid and pump drivers.
EAS	7.9 mJ - Single-pulse avalanche energy rating ensures survival during transient overvoltage events like load dump or inductive kickback.
trr / Qrr	140–210 ns / 740–1100 nC - Fast, low-charge body diode enables high-frequency (>100 kHz) switching with minimal switching loss in synchronous topologies.
RθJC	1.9 °C/W - Low junction-to-case thermal resistance allows direct mounting to metal-core PCBs or heatsinks for effective thermal management.
TJ range	−55 to +175°C - Qualified for under-hood automotive environments where ambient temperatures exceed 125°C.

Pinout & Package

D-Pak (TO-252AA) package: surface-mount, single-sided heat dissipation via exposed drain pad; 3-pin configuration with G-S-D terminal layout optimized for low-inductance PCB routing.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control electrode	Logic-level compatible (VGS(th) = 1.0–2.0 V); requires ≤10 V drive for full enhancement; total gate charge Qg = 34 nC.
S (Source)	Reference node / return path	Connected to system ground or low-side switch node; internal source inductance LS = 7.5 nH affects high-di/dt turn-on stability.
D (Drain)	Power output / high-side connection	Exposed copper pad serves as primary thermal path and high-current drain terminal; internal drain inductance LD = 4.5 nH.

Key Features

Feature	Design Value
Automotive qualification	AEC-Q101 qualified for engine control units, transmission control modules, and battery management systems.
Full avalanche rating	Repetitive avalanche allowed up to TJmax - eliminates need for external clamping in inductive load switching.
Low RDS(on) × Qg figure of merit	~3.5 Ω·nC - balances conduction and switching losses for high-efficiency 100 kHz–500 kHz DC-DC stages.
Fast body diode	trr = 140–210 ns with soft recovery - reduces EMI and voltage overshoot during freewheeling in motor drives.
Lead-free & RoHS compliant	Meets automotive environmental requirements; compatible with Pb-free reflow profiles (300°C/10 s).

Applications

Use Value: Fast trr and low Qrr reduce reverse recovery loss; logic-level gate enables direct drive from SiC gate driver without level-shifting.

Electric Power Steering (EPS) Motor Phase Leg

Automotive HVAC Blower Motor Inverter

Use Scenario: Half-bridge leg in three-phase inverter driving brushless DC motor in electric power steering column module.

IC Role / Device Role / Timing Role: Low-side switch in 60–120 kHz PWM-driven inverter; handles peak currents ≥30 A with short-circuit robustness.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL100N10F7	100 V, 100 mΩ RDS(on), 100 A ID, PowerFLAT 5x6 package, lower RθJA but no AEC-Q101 certification	Targeted at industrial motor drives; lacks automotive qualification and avalanche rating documentation	Select only for non-automotive 24 V systems requiring higher peak current headroom
IRLR8729PbF	75 V, 7.8 mΩ RDS(on), TO-252, AEC-Q101 qualified, lower voltage rating and higher conduction loss at 100 V bias	Optimized for 12 V/24 V low-voltage automotive loads; insufficient for 48 V or load-dump tolerant designs	Prefer when system VDD ≤ 40 V and RDS(on) priority outweighs voltage margin

Compared with STL100N10F7 and IRLR8729PbF, AUIRLR3410 uniquely balances 100 V rating, AEC-Q101 compliance, and 105 mΩ RDS(on) in D-Pak - making it the only option qualified for 48 V automotive power conversion where both voltage margin and thermal performance are critical.

FAQ

Is AUIRLR3410 suitable for high-frequency switching above 500 kHz?

No - while its Qg = 34 nC and tr/tf = 53/26 ns support operation up to ~300 kHz in hard-switched topologies, gate drive losses and body diode recovery limitations make it suboptimal above 500 kHz. For >500 kHz, consider devices with lower Qg and optimized Qgd/Crss ratios.

Can AUIRLR3410 replace AUIRLR3110 in existing designs?

Yes, with verification - both are AEC-Q101 D-Pak N-channel MOSFETs, but AUIRLR3410 has higher V(BR)DSS (100 V vs. 60 V) and slightly higher RDS(on) (105 mΩ vs. 90 mΩ). It is safe for 60 V systems but may require gate drive adjustment due to higher Qg (34 nC vs. 25 nC).

What is the maximum recommended PCB copper area for thermal relief?

Per IR application note AN-994, use a minimum 1" × 1" (25.4 mm × 25.4 mm) FR-4 PCB copper pour connected to the exposed drain pad via ≥4 thermal vias (0.3 mm diameter, filled or plated) to achieve RθJA ≈ 50 °C/W. Larger areas further reduce thermal resistance.

Does AUIRLR3410 support paralleling for higher current capacity?

Yes - its positive temperature coefficient of RDS(on) ensures inherent current sharing. However, layout symmetry (matched gate and source inductance) and individual gate resistors (≥10 Ω) are mandatory to prevent oscillation and ensure balanced dynamic current distribution across paralleled devices.
