Product details

Overview

AUIRFR024NTRL from Infineon is an automotive-grade N-channel D-Pak (TO-252AA) HEXFET® Power MOSFET with 55 V V_BRDSS, 0.075 Ω R_DS(on) max at V_GS = 10 V and I_D = 10 A, 17 A continuous drain current at T_C = 25°C, and 175°C maximum junction temperature - deployed in high-reliability engine control modules and DC motor drivers.

For engineers reviewing the AUIRFR024NTRL datasheet, AUIRFR024NTRL pinout, AUIRFR024NTRL application, or AUIRFR024NTRL equivalent, key selection criteria include its 5.0 V/ns peak diode recovery dv/dt rating, fully rated repetitive avalanche capability up to T_jmax, and RoHS-compliant lead-free construction validated per AEC-Q101.

Technical Context

This MOSFET employs Infineon's advanced planar silicon process to achieve low on-resistance per die area while maintaining robust dynamic performance. Its gate charge profile (Q_g = 20 nC, Q_gd = 7.6 nC) supports fast switching in hard-switched 12 V/24 V automotive systems with minimal drive loss.

The device integrates a co-packaged body diode with t_rr = 56–83 ns and Q_rr = 120–180 nC, enabling efficient freewheeling in inductive loads. Thermal design is supported by R_θJC = 3.3°C/W and R_θJA = 50°C/W (PCB mount), allowing sustained 12 A operation at T_C = 100°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BRDSS	55 V - Withstands transient overvoltage up to 55 V in 12 V/24 V automotive battery systems without breakdown.
R_DS(on) max	0.075 Ω @ V_GS = 10 V, I_D = 10 A - Enables <1.5 W conduction loss at 12 A, critical for thermally constrained ECUs.
I_D continuous	17 A @ T_C = 25°C - Supports high-current solenoid and fan motor drives with margin before thermal derating.
E_AS	71 mJ - Single-pulse avalanche energy rating ensures survival during inductive turn-off transients in relay/motor circuits.
dv/dt rating	5.0 V/ns - Prevents spurious turn-on during fast voltage transitions in noisy under-hood environments.
t_r/t_f	34 ns / 27 ns - Fast edge rates reduce switching losses in PWM-controlled DC-DC converters and motor inverters.
T_J range	−55°C to +175°C - Qualified for under-hood placement in powertrain and chassis control units per AEC-Q101.

Pinout & Package

D-Pak (TO-252AA) package with exposed drain pad for thermal enhancement; surface-mount footprint optimized for PCB heat spreading and automated assembly.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control input	Receives 10 V logic-level drive; 20 nC total gate charge requires low-impedance driver to minimize switching time.
D (Drain)	High-side power output	Connected to load supply rail; electrically tied to exposed metal tab for thermal conduction and EMI shielding.
S (Source)	Power return path	Reference node for gate drive; internal source inductance (L_S = 7.5 nH) affects di/dt-induced voltage spikes during turn-off.

Key Features

Feature	Design Value
Fully avalanche rated	Repetitive avalanche energy E_AR = 4.5 mJ up to T_jmax - eliminates need for external snubbers in inductive switching.
Dynamic dv/dt immunity	5.0 V/ns - suppresses false triggering in high-noise engine bay environments without gate resistors.
Automotive qualification	AEC-Q101 qualified - meets stress test requirements for temperature cycling, HTRB, and UHAST in safety-critical systems.
Low R_DS(on) × Q_g	0.075 Ω × 20 nC = 1.5 Ω·nC - balances conduction and switching loss for optimal efficiency in 100–200 kHz PWM applications.
Body diode performance	t_rr = 56–83 ns, Q_rr = 120–180 nC - enables clean commutation in half-bridge motor drivers without external freewheeling diodes.

Applications

IC Role / Device Role / Timing Role: High-efficiency half-bridge low-side switch operating at 20 kHz with 0–100% duty cycle.

Use Value: 34 ns rise time and 27 ns fall time enable precise duty-cycle resolution and minimal switching loss at full load.

Transmission Solenoid Actuator

Electric Power Steering (EPS) Assist Motor

Use Scenario: Driving linear solenoids for hydraulic pressure modulation in automatic transmissions.

IC Role / Device Role / Timing Role: Constant-current regulated switch with fast turn-off to prevent overshoot during gear shifts.

Use Value: 5.0 V/ns dv/dt rating prevents unintended turn-on during rapid bus voltage collapse across solenoid inductance.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP55NF06L	60 V V_BRDSS, 0.014 Ω R_DS(on), TO-220 package, non-automotive grade	Lacks AEC-Q101 qualification and 175°C rating; higher R_DS(on) at elevated temperature	Acceptable for non-safety-critical 12 V industrial controls but not for under-hood automotive use.
IRFZ44NPBF	55 V V_BRDSS, 0.028 Ω R_DS(on), TO-220, commercial grade, no avalanche rating	No repetitive avalanche capability; 150°C max T_J; unqualified for automotive thermal cycling	Lower cost option for consumer-grade DC motor drives where reliability margins are relaxed.

Compared with STP55NF06L and IRFZ44NPBF, AUIRFR024NTRL delivers guaranteed automotive reliability through AEC-Q101 validation, 175°C operation, and specified repetitive avalanche endurance - essential for engine bay deployment where thermal and electrical stress exceed commercial-grade limits.

FAQ

Is AUIRFR024NTRL pin-compatible with AUIRFU024N?

No - AUIRFR024NTRL uses the D-Pak (TO-252AA) package with drain-connected tab, while AUIRFU024N is in I-Pak (TO-251) with isolated tab. Footprint, thermal path, and mounting differ; PCB redesign is required for substitution.

What gate drive voltage is required for full enhancement?

AUIRFR024NTRL achieves R_DS(on) ≤ 0.075 Ω at V_GS = 10 V. Gate threshold voltage ranges from 2.0 V to 4.0 V, but reliable saturation and low switching loss require ≥10 V drive with ≤24 Ω series resistance.

Does this MOSFET require a gate resistor for automotive EMI compliance?

While not mandatory, a 10–24 Ω gate resistor is recommended to dampen ringing caused by L_S = 7.5 nH and L_D = 4.5 nH, especially in high-di/dt applications like injector driving - improving EMC performance per CISPR 25 Class 5.

Can AUIRFR024NTRL replace IRFZ24N in existing designs?

Yes, with caveats: AUIRFR024NTRL offers lower R_DS(on) (0.075 Ω vs. 0.07 Ω typical), higher I_D (17 A vs. 18 A), and AEC-Q101 qualification - but requires verification of thermal layout due to D-Pak's different R_θJA (50°C/W vs. 62°C/W for TO-220).
