Product details

Overview

AUIRLL024ZTR from Infineon is an automotive-grade N-channel logic-level HEXFET® Power MOSFET in SOT-223 package, rated for 55 V V_DS, 48 mΩ R_DS(on) @ 10 V_GS, and 5.0 A continuous drain current at 25°C. It delivers fast switching (t_r = 33 ns), 150°C junction operation, and repetitive avalanche capability-designed for high-reliability DC-DC converters, motor drivers, and body control modules in passenger vehicles.

For engineers reviewing the AUIRLL024ZTR datasheet, AUIRLL024ZTR pinout, AUIRLL024ZTR application, or AUIRLL024ZTR equivalent, key selection criteria include its logic-level gate drive compatibility (V_GS(th) = 1.0–3.0 V), low thermal resistance (R_θJA = 45 °C/W on copper PCB), and automotive qualification per AEC-Q101 standards.

Technical Context

This MOSFET employs Infineon's advanced planar HEXFET process to minimize conduction losses while maintaining robust avalanche performance. Its 48 mΩ R_DS(on) at 10 V_GS and 80 mΩ at 5 V_GS enables direct microcontroller GPIO driving without level-shifting. The device supports unclamped inductive switching up to 38 mJ (tested) and 21 mJ (thermally limited).

Thermal design is enabled by a 150°C maximum junction temperature and transient thermal impedance profile validated for pulse widths down to 10 µs. The integrated body diode exhibits t_rr = 15–23 ns and Q_rr = 9.1–14 nC, supporting synchronous rectification in buck topologies with minimal recovery loss.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	55 V - Withstands automotive load-dump transients up to ISO 7637-2 Pulse 5a (58 V peak).
R_DS(on) @ 10 V_GS	48 mΩ typ. - Enables ≤0.72 W conduction loss at 3.0 A, reducing heatsink requirements in space-constrained modules.
I_D cont. @ 25°C	5.0 A - Supports continuous operation in 12 V automotive subsystems like window lift or seat actuator drivers.
Q_g	7.0–11 nC - Low gate charge allows efficient 100–500 kHz PWM switching with <10 mA gate driver current.
t_r/t_f	33 ns / 15 ns - Minimizes switching transition time, reducing overlap loss in half-bridge configurations.
E_AS (tested)	38 mJ - Validates robustness against inductive kickback in solenoid and relay drive applications.
T_J max	+150°C - Meets under-hood temperature requirements for engine bay-mounted electronics.

Pinout & Package

SOT-223 package with exposed drain pad for enhanced thermal dissipation; surface-mount footprint optimized for PCB copper area mounting.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Drain)	Main power path output	Internally connected to exposed metal tab; must be soldered to ≥1 in² copper pour for R_θJA = 45 °C/W.
Pin 2 (Gate)	Control input	Logic-level compatible (V_GS(th) ≤ 3.0 V); requires <100 pF gate capacitance buffering for EMI suppression.

Key Features

Feature	Design Value
Automotive qualification	AEC-Q101 qualified - Validated for temperature cycling, humidity, and mechanical shock per automotive reliability standards.
Logic-level gate drive	V_GS(th) = 1.0–3.0 V - Directly driven by 3.3 V or 5 V microcontrollers without external level shifters.
Repetitive avalanche rating	EAR = 100% of E_AS (tested) - Enables reliable operation in unclamped inductive switching (e.g., fuel injector drivers).
Low R_DS(on) × Q_g figure-of-merit	~336 mΩ·nC - Balances conduction and switching losses for high-efficiency 100–300 kHz DC-DC stages.
Body diode softness	Q_rr = 9.1–14 nC, t_rr = 15–23 ns - Reduces voltage overshoot and EMI during freewheeling in synchronous buck converters.

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
STL130N5LF6AG	60 V V_DS, 3.8 mΩ R_DS(on) @ 10 V_GS, DFN5x6 package - lower R_DS(on) but higher Q_g (27 nC) and no AEC-Q101 certification.	Requires gate driver IC due to higher Q_g; unsuitable for AEC-Q101-compliant systems without requalification.	Select only for non-automotive industrial DC-DC where ultra-low R_DS(on) outweighs qualification needs.
ON Semiconductor NTMFS4C09NT1G	40 V V_DS, 5.2 mΩ R_DS(on) @ 10 V_GS, SO-8FL package - higher voltage margin insufficient for 12 V automotive load dump.	Limited to 40 V systems; cannot withstand ISO 7637-2 Pulse 5a (58 V) without external clamping.	Use only in 5 V or 3.3 V logic-supplied loads where V_DS derating is acceptable.

Compared with STL130N5LF6AG and NTMFS4C09NT1G, AUIRLL024ZTR provides the only AEC-Q101-qualified SOT-223 solution with balanced R_DS(on)/Q_g and full 55 V load-dump tolerance-making it optimal for cost-sensitive, space-constrained automotive body electronics requiring zero requalification effort.

FAQ

Is AUIRLL024ZTR suitable for linear-mode operation?

Yes-its 150°C maximum junction temperature, stable R_DS(on) vs. temperature coefficient (+0.049 V/°C), and SOA curve validated to 100 µs pulses support linear-mode use in LED current regulation and analog dimming circuits. Derate power dissipation per the 0.02 W/°C linear derating factor when ambient exceeds 25°C.

What is the recommended PCB layout for thermal performance?

Mount the SOT-223 package on ≥1 in² of 2 oz copper connected directly to the drain pin via multiple thermal vias. Use minimum 0.5 mm trace width for source and gate connections to limit inductance. Keep gate loop area <10 mm² to suppress ringing during 33 ns rise time operation.

Does AUIRLL024ZTR require a gate resistor for automotive EMI compliance?

Yes-a 10–22 Ω series gate resistor is recommended to dampen high-frequency oscillation caused by PCB trace inductance interacting with Q_gd = 4.0 nC. This reduces dv/dt-induced coupling into adjacent CAN/LIN lines and meets CISPR 25 Class 5 radiated emissions limits in vehicle harness environments.

Can AUIRLL024ZTR replace older AUIRLZ44Z in existing designs?

No-AUIRLZ44Z has 55 V V_DS but 22 mΩ R_DS(on) and different SOA; AUIRLL024ZTR's higher R_DS(on) (48 mΩ) increases conduction loss by ~118%, requiring thermal revalidation. Its lower Q_g (7–11 nC vs. 42 nC) improves switching efficiency but does not offset the R_DS(on) penalty in high-current steady-state operation.
