Product details

Overview

AUIRFR9024NTRL from Infineon is a P-channel automotive-grade HEXFET® Power MOSFET in D-Pak (TO-252AA) package, rated for -55 V V_DS, 0.175 Ω R_DS(on) at -10 V V_GS, and -11 A continuous drain current at 25°C. It operates up to +150°C junction temperature, features full avalanche rating, and is optimized for high-reliability automotive load switching applications including body control modules and power distribution units.

For engineers reviewing the AUIRFR9024NTRL datasheet, AUIRFR9024NTRL pinout, AUIRFR9024NTRL application, or AUIRFR9024NTRL equivalent, key selection criteria include its -55 V breakdown voltage, -11 A continuous current capability at elevated temperature, fast switching times (t_d(on) = 13 ns, t_f = 37 ns), low gate charge (Q_g = 19 nC), and automotive qualification per AEC-Q101.

Technical Context

This P-channel MOSFET employs Infineon's advanced planar silicon process to achieve low on-resistance per die area while maintaining rugged unclamped inductive switching performance. Its dynamic dv/dt rating of -10 V/ns and fully rated repetitive avalanche energy (E_AR = 3.8 mJ) support robust operation in noisy automotive environments with inductive loads.

The device integrates a fast, low-V_SD body diode (V_SD = -1.6 V at -7.2 A) with trr = 47–71 ns and Q_rr = 84–130 nC, enabling efficient synchronous rectification and reverse recovery in bidirectional power paths such as battery protection and reverse polarity protection circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-55 V - Withstands reverse-biased drain-source voltage up to this level without breakdown, suitable for 42 V automotive systems and 24 V industrial rails.
R_DS(on)	0.175 Ω max @ V_GS = -10 V, I_D = -6.6 A - Enables low conduction loss in high-current load switches; <1.2 W dissipation at -7 A.
I_D (cont)	-11 A @ T_C = 25°C - Supports sustained load currents typical of solenoid drivers, fan controllers, and lighting modules.
Q_g	19 nC - Low total gate charge reduces driver power requirement and enables efficient PWM control at >100 kHz.
t_f	37 ns - Fast fall time minimizes switching transition losses during turn-off in high-frequency DC-DC and motor drive stages.
E_AS	62 mJ - Single-pulse avalanche energy rating ensures survival under transient overvoltage events like load dump or inductive kickback.
T_J range	-55°C to +150°C - Qualified for under-hood automotive use where ambient temperatures exceed 105°C and thermal cycling is severe.

Pinout & Package

D-Pak (TO-252AA) package with exposed drain pad for enhanced thermal performance; thermally efficient mounting on PCB copper pour; lead-free and RoHS compliant.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control input	Accepts -10 V logic-level drive to fully enhance channel; ±20 V absolute max gate voltage limits external driver design.
D (Drain)	High-side power output	Connected to load supply rail; electrically tied to exposed metal tab for low-inductance, high-current return path and thermal conduction.
S (Source)	Power return / reference	Common node for load current return and gate drive reference; source-to-drain diode enables reverse current blocking or freewheeling.

Key Features

Feature	Design Value
Automotive qualification	AEC-Q101 qualified - Validated for reliability across temperature cycling, humidity, mechanical shock, and lifetime stress in automotive ECUs.
Full avalanche rating	Repetitive avalanche energy E_AR = 3.8 mJ - Allows safe operation during unclamped inductive switching without external snubbers in relay replacement designs.
Low R_DS(on) at high T_J	R_DS(on) increases only ~1.8× from 25°C to 150°C - Maintains predictable conduction loss in thermally constrained enclosures.
Fast body diode	t_rr = 47–71 ns, Q_rr = 84–130 nC - Reduces reverse recovery loss and EMI in bidirectional power paths like battery backup and reverse polarity protection.
Dynamic dv/dt immunity	-10 V/ns rated - Resists false turn-on due to high-slew-rate noise in 48 V mild-hybrid systems and motor phase-legs.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP12PF06	V_DS = -60 V, R_DS(on) = 0.22 Ω @ -10 V, non-automotive grade	Lacks AEC-Q101 qualification and repetitive avalanche rating	Acceptable for cost-sensitive industrial prototypes but not for production automotive systems.
IRF9540NPBF	V_DS = -100 V, R_DS(on) = 0.2 Ω @ -10 V, TO-220 package, no automotive qualification	Higher voltage margin but larger footprint and lower current density; no guaranteed 150°C operation	Suitable for legacy 12 V designs requiring higher V_DS margin, but not for space-constrained or high-temp automotive PCBs.

Compared with STP12PF06 and IRF9540NPBF, AUIRFR9024NTRL delivers superior thermal efficiency in D-Pak, guaranteed automotive reliability, and lower conduction loss at typical automotive operating temperatures-making it the preferred choice for new AEC-Q101-compliant designs.

FAQ

Is AUIRFR9024NTRL pin-compatible with AUIRFU9024N?

No. AUIRFR9024NTRL uses the D-Pak (TO-252AA) package with Drain-Source-Gate pin order (D-S-G), while AUIRFU9024N uses the I-Pak (TO-251) package with Drain-Gate-Source order (D-G-S). Physical layout, thermal pad configuration, and PCB footprint differ significantly-direct substitution requires board redesign.

What is the maximum recommended gate resistor for driving AUIRFR9024NTRL at 20 kHz PWM?

A 24 Ω gate resistor is validated in the datasheet for switching characterization (t_d(off), t_f). For 20 kHz operation, a 10–22 Ω resistor balances switching speed and gate driver stress; values below 10 Ω increase EMI risk without meaningful efficiency gain due to internal L_S/L_D limits.

Does AUIRFR9024NTRL require a gate pull-up resistor in high-side P-channel configurations?

Yes. A gate pull-up resistor (typically 10–100 kΩ to V_CC) is required to ensure the MOSFET remains off during microcontroller reset or I/O floating states. Without it, leakage or noise may partially enhance the channel, causing unintended load activation or shoot-through in half-bridge topologies.

Can AUIRFR9024NTRL be used in parallel for higher current capacity?

Parallel operation is not recommended. The device exhibits positive R_DS(on) temperature coefficient, but mismatched threshold voltages (V_GS(th) = -2.0 to -4.0 V) and layout parasitics cause uneven current sharing. For >11 A, select a single higher-current automotive MOSFET (e.g., AUIRLR3410) instead of paralleling.
