Product details

Overview

AUIRLS4030TRL from Infineon Technologies is an automotive-qualified N-channel D2PAK (TO-263) HEXFET® Power MOSFET with 100V V_DSS, 3.4mΩ typ. R_DS(on) at V_GS = 10V, 180A continuous drain current at T_C = 25°C, and 175°C maximum junction temperature-designed for high-current DC-DC converters and motor control in engine management systems.

For engineers reviewing the AUIRLS4030TRL datasheet, AUIRLS4030TRL pinout, AUIRLS4030TRL application, or AUIRLS4030TRL equivalent, key selection criteria include logic-level gate drive compatibility (V_GS(th) = 1.0–2.5V), repetitive avalanche rating (E_AR = 300mJ at T_J = 25°C), and thermal resistance R_θJC = 0.40°C/W for high-power automotive PCB mounting.

Technical Context

This MOSFET employs advanced planar HEXFET processing to achieve ultra-low on-resistance per die area while maintaining robustness under harsh automotive transients. Its body diode features low V_SD = 1.3V max and fast trr = 50ns (T_J = 25°C), enabling efficient synchronous rectification and unclamped inductive switching.

The device supports logic-level gate drive down to 4.5V, with Q_g = 87nC typ. and Q_gd = 45nC-enabling fast turn-on (t_d(on) = 74ns) and controlled dv/dt during hard-switching. Repetitive avalanche capability is validated up to I_AS = 110A with pulse width ≤400μs and duty cycle ≤2%.

Key Specifications

Pinout & Package

Supplied in D2PAK (TO-263) surface-mount package with exposed drain pad for low thermal resistance (R_θJC = 0.40°C/W). The three-terminal configuration supports high-current PCB routing and thermal vias directly beneath the drain tab.

Pin/Terminal	Circuit Role	Design Meaning
Tab / Pin 2 (Drain)	Main power output path	Electrically connected to copper drain die area; must be soldered to large thermal pad with ≥6 thermal vias for R_θJA ≤ 40°C/W.
Pin 1 (Gate)	Control input	High-impedance MOS gate requiring <100nA leakage; sensitive to ESD-requires series resistor (2.7Ω typical) to damp ringing.
Pin 3 (Source)	Reference node for gate drive and current sensing	Connected to source metallization; used as Kelvin sense point in precision current monitoring circuits.

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS = 4.5V, eliminating need for gate boosters in 5V microcontroller-driven systems.
Repetitive avalanche rated	Validated for ≥1000 cycles at I_AS = 110A, enabling robust operation in unclamped inductive loads like fuel injectors.
Ultra-low R_DS(on)	3.4mΩ typ. reduces conduction loss by >35% vs. legacy 100V MOSFETs, improving thermal margin in sealed enclosures.
Automotive qualification	AEC-Q101 qualified with 175°C T_J rating-approved for safety-critical functions including EPS and brake-by-wire.
Fast body diode	t_rr = 50ns enables use in synchronous buck converters without external Schottky parallel diodes.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current automotive MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N10F7	100V, 220A, R_DS(on) = 2.9mΩ typ., DFN8 5×6 package, no integrated avalanche rating	Requires external avalanche protection circuitry; unsuitable for unclamped inductive loads without snubber design	Select only if board space is constrained and system includes active overvoltage clamping
IRFB4115PBF	150V, 110A, R_DS(on) = 5.8mΩ typ., TO-220 package, 175°C rated but not AEC-Q101 qualified	Lacks automotive qualification documentation and production traceability for safety-critical modules	Acceptable for non-safety industrial motor drives but not for OEM automotive BOMs

Compared with STL220N10F7 and IRFB4115PBF, AUIRLS4030TRL uniquely combines AEC-Q101 qualification, 175°C operation, and validated repetitive avalanche performance-making it the only choice for production-grade automotive power stages where field failure risk must be minimized.

FAQ

What is the maximum allowable gate-to-source voltage for AUIRLS4030TRL?

The absolute maximum V_GS is ±16V per datasheet Section "Absolute Maximum Ratings." Operation beyond ±16V risks irreversible gate oxide breakdown. For robust design, limit gate drive to ≤12V with transient suppression (e.g., 12V Zener clamp) to accommodate overshoot during fast switching on high-inductance PCB traces.

Can AUIRLS4030TRL be used in parallel configurations?

Yes-its positive R_DS(on) temperature coefficient (0.10%/°C) enables inherent current sharing. Use matched gate resistors (≤2.7Ω) and symmetrical PCB layout with Kelvin source connections to minimize imbalance. Derate total current by 15% versus single-device rating to account for thermal coupling between adjacent devices.

Does AUIRLS4030TRL include an integrated body diode, and what are its key parameters?

Yes-it features an integral reverse p-n junction body diode with V_SD = 1.3V max at I_S = 110A and t_rr = 50ns at T_J = 25°C. Q_rr = 88nC enables efficient commutation in synchronous rectifiers, but requires careful dv/dt control (≤2.5V/ns) to avoid spurious turn-on during diode recovery.

What is the recommended PCB footprint and thermal via strategy for D2PAK mounting?

Use the footprint specified in Infineon Application Note AN-994: 12mm × 10mm exposed drain pad with ≥6 × 0.3mm vias spaced ≤2mm apart, filled with solder or conductive epoxy. Maintain ≥1.6mm clearance from pad edge to silkscreen and ensure ≥0.5mm solder mask opening around all pins to prevent bridging during reflow.
