Product details

Overview

AUIRFR9024N 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 such as body control modules and motor drivers.

For engineers reviewing the AUIRFR9024N datasheet, AUIRFR9024N pinout, AUIRFR9024N application, or AUIRFR9024N equivalent, key selection criteria include its -55 V breakdown voltage, low on-resistance under automotive thermal constraints, fast switching (13 ns t_d(on), 37 ns t_f), repetitive avalanche capability (3.8 mJ), and D-Pak thermal performance (R_θJC = 3.3 °C/W).

Technical Context

This device implements a planar P-channel silicon structure with integrated body diode, designed for unidirectional high-side switching in 12 V/24 V automotive systems. Its gate threshold voltage (-2.0 to -4.0 V) enables direct drive from standard CMOS logic, while dynamic dv/dt rating (-10 V/ns) ensures robustness during inductive turn-off transients.

The MOSFET supports repetitive avalanche operation up to T_jmax and delivers 62 mJ single-pulse avalanche energy under defined test conditions (L = 2.8 mH, I_AS = -6.6 A). Thermal design leverages low junction-to-case resistance (3.3 °C/W) when mounted on PCBs per AN-994 footprint guidelines.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-55 V - Withstands reverse-biased drain-source voltage up to automotive battery surge levels (e.g., load dump).
R_DS(on)	0.175 Ω @ V_GS = -10 V, I_D = -6.6 A - Enables <1.2 W conduction loss at nominal 7 A load current.
I_D (continuous)	-11 A @ T_C = 25°C - Supports sustained current in engine bay-mounted power stages with adequate heatsinking.
t_f	37 ns - Reduces switching losses in PWM-driven solenoid or lamp dimming circuits operating up to 20 kHz.
E_AR	3.8 mJ - Allows repeated inductive energy clamping without derating in relay/coil driver protection schemes.
R_θJC	3.3 °C/W - Enables 11.5 W power dissipation before reaching 150°C junction limit with 38°C case rise.
Q_g	19 nC - Determines gate driver current requirement (~1.9 mA average for 100 kHz switching at 10 V swing).

Pinout & Package

D-Pak (TO-252AA) package with exposed drain pad for thermal and electrical connection; standard 3-pin configuration with G–D–S pin order (viewed from top, marking side up, leads down).

Pin/Terminal	Circuit Role	Design Meaning
Gate (G)	Control input	Receives negative V_GS to turn on; threshold range (-2.0 to -4.0 V) allows compatibility with 3.3 V/5 V microcontroller outputs via level shift.
Drain (D)	High-side power output	Connected to load supply rail; electrically and thermally tied to exposed copper pad for low-inductance, high-current return path.
Source (S)	Reference node	Common return for load current and gate drive reference; must be routed with low impedance to minimize shoot-through risk in half-bridge configurations.

Key Features

Feature	Design Value
Automotive qualification	AEC-Q101 qualified for under-hood use with guaranteed operation from -55°C to +150°C junction temperature.
Full avalanche rating	Rated for repetitive unclamped inductive switching up to T_jmax, eliminating need for external snubbers in solenoid drivers.
Low R_DS(on)	0.175 Ω enables <1.2 W conduction loss at 7 A, reducing thermal stress in space-constrained BCM modules.
Fast switching	13 ns t_d(on)/37 ns t_f minimizes transition losses in 10–20 kHz PWM applications like LED headlight dimming.
Lead-free & RoHS	Compliant with automotive environmental standards; compatible with Pb-free reflow profiles per J-STD-020.

Transmission Solenoid Control

LED Headlight Dimming

IC Role / Device Role / Timing Role: Current-regulated high-side switch with integrated body diode for freewheeling during de-energization.

Use Value: Repetitive avalanche energy (3.8 mJ) clamps inductive energy without degradation over >10⁶ cycles; -55 V V_DS accommodates battery transients.

Use Scenario: Analog-dimming front LED headlamps using constant-current PWM with minimal EMI and thermal drift.

IC Role / Device Role / Timing Role: High-side current sink modulating LED string current via duty-cycle-controlled switching.

Use Value: Low Q_g (19 nC) and fast t_d(on)/t_f reduce gate drive power and enable smooth 100–1000 Hz dimming without visible flicker.

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, no AEC-Q101 certification	Lacks automotive qualification; suitable only for industrial or non-safety-critical automotive subsystems	Select if cost sensitivity outweighs qualification requirements and thermal margin permits higher R_DS(on).
IRF9540NPBF	V_DS = -100 V, R_DS(on) = 0.2 Ω @ -10 V, TO-220 package, not automotive-qualified	Higher voltage rating but larger footprint and no thermal spec for PCB mount; no avalanche energy rating	Choose only for legacy designs requiring TO-220 mechanical fit; avoid in new automotive designs due to missing qualification and thermal data.

Compared with STP12PF06 and IRF9540NPBF, AUIRFR9024N provides verified automotive reliability, lower on-resistance in compact D-Pak, and documented repetitive avalanche capability-critical for solenoid and motor control where inductive energy management is mandatory.

FAQ

What is the maximum continuous drain current at 100°C case temperature?

The AUIRFR9024N supports -8 A continuous drain current at T_C = 100°C with V_GS = -10 V, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the D-Pak package under sustained high-temperature operation, and must be validated against actual board layout and airflow conditions.

Is a gate resistor required for safe operation?

Yes-a gate resistor (typically 10–100 Ω) is recommended to dampen ringing and control dV/dt during switching. The device's 19 nC total gate charge and fast 13 ns turn-on delay make it susceptible to oscillation without proper gate drive impedance, especially in high-di/dt inductive load applications.

Can AUIRFR9024N replace AUIRFU9024N in a design?

No-AUIRFR9024N (D-Pak) and AUIRFU9024N (I-Pak) differ in package thermal resistance and mounting geometry. While electrically identical, the D-Pak's lower R_θJC (3.3 vs. 50 °C/W for I-Pak PCB mount) and different footprint require PCB redesign and thermal validation before substitution.

Does the body diode support continuous conduction mode?

The integrated body diode is rated for -11 A continuous source current at 25°C, but its forward voltage (-1.6 V at -7.2 A) and reverse recovery characteristics (t_rr = 47–71 ns) limit use in high-frequency synchronous rectification. It is intended for freewheeling in low-duty-cycle inductive loads-not for sustained bidirectional conduction.
