Product details

Overview

AUIRLR024ZTRL from Infineon is an automotive-grade N-channel logic-level HEXFET® Power MOSFET in D-Pak (TO-252) package, rated for 55 V V_DS, 46 mΩ R_DS(on) @ 10 V_GS, and 16 A continuous drain current at T_C = 25°C. It operates up to 175°C junction temperature, supports repetitive avalanche, and delivers fast switching with 8.2 ns turn-on delay and 16 ns fall time - deployed in engine control modules, DC-DC converters, and high-side load switches.

For engineers reviewing the AUIRLR024ZTRL datasheet, AUIRLR024ZTRL pinout, AUIRLR024ZTRL application, or AUIRLR024ZTRL equivalent, key selection criteria include its 55 V breakdown voltage, 46 mΩ on-resistance at 10 V_GS, 175°C thermal rating, logic-level gate drive compatibility (V_GS(th) = 1.0–3.0 V), and D-Pak thermal performance (R_θJC = 4.28 °C/W).

Technical Context

This MOSFET employs Infineon's advanced process technology to achieve ultra-low on-resistance per silicon area while maintaining robust avalanche capability. Its gate threshold voltage (1.0–3.0 V) enables direct interfacing with 3.3 V/5 V microcontrollers, and its 6.6 nC total gate charge ensures efficient switching in high-frequency DC-DC and motor drive stages.

The device features a built-in body diode with 16 A continuous source current rating, 1.3 V forward voltage at 9.6 A, and 16 ns reverse recovery time. Repetitive avalanche operation is thermally limited but validated per Fig. 12a–12b and AN-1005, supporting unclamped inductive load handling in automotive solenoid and fuel injector drivers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	55 V - Withstands transients up to automotive load-dump conditions (ISO 7637-2 Pulse 5a).
R_DS(on) @ 10 V_GS	46 mΩ typ. - Enables <1 W conduction loss at 10 A, reducing heatsink requirements in space-constrained ECUs.

Ultra-low R_DS(on)	46 mΩ @ 10 V_GS reduces I²R losses by >30% vs. legacy 75 mΩ automotive MOSFETs at same current.
Repetitive avalanche rated	Validated per Fig. 12a–12b and AN-1005 - supports unclamped inductive switching in fuel injector drivers without failure risk.
175°C junction rating	Enables placement in high-ambient zones (e.g., near exhaust manifolds or inverters) without thermal derating penalties.
RoHS-compliant & lead-free	Meets automotive ELV Directive and JESD204B reflow profile - suitable for lead-free SMT assembly in Tier-1 production lines.

Applications

Engine Control Unit (ECU) Fuel Injector Driver

Automotive DC-DC Converter High-Side Switch

Use Scenario: Driving 12 V solenoid-type fuel injectors in gasoline direct injection systems with PWM frequencies up to 20 kHz.

IC Role / Device Role / Timing Role: High-side N-channel switch controlling injector coil current; handles 16 A peak pulses with <16 ns fall time to minimize dwell-time error.

Use Value: Repetitive avalanche rating absorbs inductive kickback without snubber, and 175°C rating sustains operation during prolonged idle-stop cycles.

Use Scenario: High-side synchronous rectifier in 12 V → 5 V/3.3 V buck converter for infotainment head units.

IC Role / Device Role / Timing Role: Main power switch operating at 500 kHz; leverages 6.6 nC Q_g and 46 mΩ R_DS(on) to maintain >92% efficiency at 8 A load.

Use Value: Low gate charge minimizes driver IC power consumption; D-Pak thermal resistance (4.28 °C/W) enables convection-only cooling on 2 oz copper PCB.

Body Control Module (BCM) High-Current Load Switch

Electric Power Steering (EPS) Motor Phase Driver

Use Scenario: Controlling radiator cooling fan, HVAC blower, or headlight ballast in centralized BCM architecture.

IC Role / Device Role / Timing Role: Logic-level controlled high-side switch; interfaces directly with 3.3 V CAN/LIN transceiver MCU GPIOs.

Use Value: 1.0–3.0 V V_GS(th) guarantees turn-on margin across voltage tolerances; 55 V V_DS withstands ISO 16750-2 jump-start transients.

Use Scenario: Half-bridge high-side switch in 48 V EPS motor gate driver stage, handling 12 A RMS phase current.

IC Role / Device Role / Timing Role: Fast-switching N-channel MOSFET in three-phase inverter leg; uses 8.2 ns t_d(on) and 16 ns t_f to reduce dead-time losses.

Use Value: 175°C rating accommodates proximity to motor housing; repetitive avalanche tolerance prevents failure during sudden torque reversal events.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL100N5LF6AG	60 V V_DS, 4.5 mΩ R_DS(on) @ 10 V_GS, 100 A I_D - lower R_DS(on) but larger H2PAK-6 package and higher Q_g (35 nC).	Better suited for high-current traction inverters; less optimal for space-constrained ECU boards due to footprint and gate drive overhead.	Select when system prioritizes conduction loss over layout density and gate drive simplicity.
IRLR024NTRPBF	55 V V_DS, 46 mΩ R_DS(on) @ 10 V_GS, but commercial-grade (−55°C to +175°C) - no AEC-Q101 qualification or automotive PPAP support.	Limited to non-safety-critical consumer or industrial applications; lacks automotive traceability, lot-level testing, and extended temperature validation.	Choose only for prototyping or cost-sensitive non-automotive designs where AEC-Q101 compliance is not required.

Compared with STL100N5LF6AG and IRLR024NTRPBF, AUIRLR024ZTRL uniquely balances automotive qualification, D-Pak compactness, logic-level drive, and validated avalanche robustness - making it optimal for production ECU, BCM, and EPS subsystems requiring zero-failure field reliability.

FAQ

Is AUIRLR024ZTRL qualified to AEC-Q101 standards?

Yes, AUIRLR024ZTRL is fully AEC-Q101 qualified for automotive applications. It undergoes stress testing including HTGB, HTRB, UHAST, and temperature cycling per AEC-Q101 Rev D, with full PPAP documentation available upon request for Tier-1 production programs.

What is the maximum recommended gate resistor value for driving AUIRLR024ZTRL in a 20 kHz PWM application?

For 20 kHz PWM with minimal switching loss, a gate resistor of 10 Ω to 22 Ω is recommended. This range balances rise/fall times (~43 ns tr, ~16 ns tf) against ringing suppression, especially when paired with MCU GPIOs capable of ≥20 mA sink/source current.

Can AUIRLR024ZTRL be used in parallel configurations for higher current handling?

Yes, AUIRLR024ZTRL supports paralleling due to its positive R_DS(on) temperature coefficient (see Fig. 10). To ensure current sharing, use matched gate resistors, symmetrical PCB layout, and common-source Kelvin sensing - verified in Infineon application note AN-1087 for multi-MOSFET arrays.

Does the D-Pak package require thermal vias under the drain pad for automotive ambient temperatures up to 105°C?

Yes. For sustained operation at T_A = 105°C, at least six 0.3 mm diameter thermal vias (filled or plated) connecting the drain pad to ≥2 internal ground planes are required to achieve effective R_θJA ≤ 35 °C/W, as validated in Infineon's AN-994 layout guidelines for TO-252 packages.
