Product details

Overview

AUIRLR014NTRL from Infineon is an automotive-grade N-channel D-Pak (TO-252AA) HEXFET® Power MOSFET with 55 V V_DS, 0.14 Ω R_DS(on) @ 10 V_GS, 10 A continuous drain current at T_C = 25°C, and 175°C maximum junction temperature-designed for high-efficiency DC-DC converters and motor control in engine management systems.

For engineers reviewing the AUIRLR014NTRL datasheet, AUIRLR014NTRL pinout, AUIRLR014NTRL application, or AUIRLR014NTRL equivalent, key selection criteria include logic-level gate drive compatibility (V_GS(th) = 1.0–3.0 V), avalanche ruggedness (E_AS = 35 mJ), thermal performance (R_θJC = 5.3°C/W), and automotive qualification per AEC-Q101.

Technical Context

This N-channel enhancement-mode MOSFET employs advanced planar silicon processing to achieve low on-resistance per die area while maintaining robust unclamped inductive switching capability. Its dynamic dV/dt rating of 5.0 V/ns and fully rated repetitive avalanche operation up to T_jmax support reliable operation in noisy automotive power rails.

The device features fast switching (t_r = 47 ns, t_f = 23 ns) and optimized gate charge (Q_g = 7.9 nC, Q_gd = 4.4 nC), enabling high-frequency PWM control in 12 V/24 V battery-fed systems. Body diode parameters-including V_SD = 1.3 V @ I_S = 6.0 A and t_rr = 37–56 ns-are characterized across -55°C to +175°C for cold-crank and under-hood thermal environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	55 V - supports 12 V/24 V automotive battery systems with margin against load-dump transients
R_DS(on) max	0.14 Ω @ V_GS = 10 V, I_D = 6 A - enables <1.4 W conduction loss at 10 A continuous current
I_D continuous	10 A @ T_C = 25°C - suitable for medium-power motor drivers and solenoid controls
E_AS	35 mJ - single-pulse avalanche energy allows safe operation during inductive turn-off without snubbers
t_r/t_f	47 ns / 23 ns - supports >200 kHz switching in synchronous buck regulators
T_J range	-55°C to +175°C - qualified for under-hood applications including transmission control units
Q_g	7.9 nC - compatible with standard logic-level gate drivers (e.g., TC4427, UCC27531)

Pinout & Package

Package: D-Pak (TO-252AA), surface-mount, thermally enhanced with exposed drain pad. Mounting requires FR-4 PCB with recommended footprint per AN-994.

Pin/Terminal	Circuit Role	Design Meaning
G	Gate	Logic-level input (V_GS(th) = 1.0–3.0 V); requires <7.9 nC charge for full enhancement
D	Drain	Main high-side or low-side power path; electrically connected to exposed tab for thermal conduction
S	Source	Reference node for gate drive and current sensing; body diode anode

Key Features

Feature	Design Value
Automotive qualification	AEC-Q101 qualified for engine control, transmission, and ADAS subsystems
Logic-level gate drive	Operates fully enhanced from 4.5 V_GS (R_DS(on) = 0.21 Ω), eliminating need for gate boosters
Fully avalanche rated	Repetitive avalanche allowed up to T_jmax; E_AR = 2.8 mJ supports cyclic inductive loads
Thermal robustness	R_θJC = 5.3°C/W enables >20 W dissipation with minimal heatsink in D-Pak footprint
Dynamic dV/dt immunity	Rated 5.0 V/ns - suppresses false turn-on in high-noise motor drive and alternator circuits

Applications

Engine Control Unit (ECU) Fuel Injector Driver

12 V Automotive DC-DC Converter

Use Scenario: High-speed switching of fuel injectors in gasoline direct injection systems with 12 V battery supply and transient-rich under-hood environment.

IC Role / Device Role / Timing Role: Low-side switch controlling injector coil current; must sustain 10 A peak pulses with <100 ns turn-off to meet precise fuel metering timing.

Use Value: Avalanche rating (E_AS = 35 mJ) absorbs inductive kickback without external clamping; 175°C T_J ensures reliability during extended idling.

Use Scenario: Synchronous rectifier in 12 V → 3.3 V/5 V buck converter powering infotainment microcontrollers.

IC Role / Device Role / Timing Role: High-efficiency power FET operating at 500 kHz PWM; body diode used during dead-time conduction.

Use Value: Low R_DS(on) (0.14 Ω) reduces conduction loss; fast t_f (23 ns) minimizes shoot-through risk in synchronous topology.

Electric Power Steering (EPS) Motor Phase Switch

Automotive HVAC Blower Motor Controller

Use Scenario: Half-bridge phase leg in 24 V EPS system requiring bidirectional current handling and fault tolerance.

IC Role / Device Role / Timing Role: N-channel high-side or low-side switch in three-phase inverter; subjected to regenerative braking currents and EMI.

Use Value: Dynamic dV/dt rating (5.0 V/ns) prevents spurious turn-on during fast voltage transitions; AEC-Q101 qualification ensures long-term field reliability.

Use Scenario: PWM-controlled blower motor driver in climate control module, operating continuously at elevated ambient temperatures.

IC Role / Device Role / Timing Role: Low-side power switch modulating motor speed via 20–100 Hz PWM; handles 8 A continuous current with thermal cycling.

Use Value: R_θJC = 5.3°C/W allows direct PCB copper pour cooling; 175°C T_J rating maintains performance at +85°C case temperature.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL100N5LF6AG	60 V V_DS, 0.0095 Ω R_DS(on) @ 10 V_GS, PowerFLAT 5x6 package, lower R_DS(on) but higher Q_g (22 nC)	Better conduction efficiency at high current; less suitable for high-frequency switching due to gate charge	Select when thermal budget dominates over switching loss; verify PCB layout for larger thermal pad
IRLR024NTRLPBF	55 V V_DS, 0.077 Ω R_DS(on) @ 10 V_GS, same D-Pak package, non-automotive grade (no AEC-Q101)	Higher performance in lab prototypes; not approved for production automotive use	Acceptable for pre-production validation only; requires requalification for series production

Compared with STL100N5LF6AG and IRLR024NTRLPBF, AUIRLR014NTRL delivers balanced trade-offs: sufficient R_DS(on) for cost-sensitive designs, guaranteed automotive qualification, and optimized gate charge for 200+ kHz operation-making it ideal for volume production in engine and chassis control modules.

FAQ

Is AUIRLR014NTRL pin-compatible with standard D-Pak discrete MOSFETs?

Yes, AUIRLR014NTRL uses the industry-standard D-Pak (TO-252AA) footprint with Gate-Drain-Source pin order (G-D-S). The exposed drain pad is electrically tied to the drain terminal and must be soldered to a thermal copper area per Infineon's AN-994 layout guidelines.

What is the maximum allowable gate-to-source voltage for reliable operation?

The absolute maximum V_GS is ±16 V. Operation beyond this risks permanent gate oxide damage. For robust design, gate drive should be limited to 12 V maximum with transient suppression, especially in automotive environments where load dump can induce overshoot.

Does AUIRLR014NTRL require a gate resistor for stability in switching applications?

Yes-a gate resistor (typically 5–22 Ω) is required to dampen ringing caused by gate loop inductance and prevent oscillation. The datasheet specifies t_d(on), t_r, t_d(off), and t_f using R_G = 6.2 Ω; deviating significantly affects switching speed and EMI profile.

Can the body diode be used for freewheeling in synchronous rectification?

Yes-the integral body diode is characterized for continuous source current up to 10 A and pulsed current up to 40 A, with t_rr = 37–56 ns and Q_rr = 48–71 nC. It is suitable for freewheeling in low-duty-cycle, low-frequency applications but not recommended for high-frequency synchronous rectification without careful dead-time optimization.
