Product details

Overview

AUIRFR2407 from Infineon is an automotive-grade N-channel D-Pak (TO-252AA) HEXFET® Power MOSFET with 75V V_DS, 21.8 mΩ typical R_DS(on) at V_GS = 10 V, 42 A continuous drain current at T_C = 25°C, 175°C maximum junction temperature, and full avalanche rating-designed for high-efficiency DC-DC converters and motor control in engine management systems.

For engineers reviewing the AUIRFR2407 datasheet, AUIRFR2407 pinout, AUIRFR2407 application, or AUIRFR2407 equivalent, key selection criteria include its dynamic dV/dt rating (5.0 V/ns), repetitive avalanche capability up to T_jmax, low gate charge (74 nC typ.), and RoHS-compliant lead-free construction validated per AEC-Q101.

Technical Context

This MOSFET employs Infineon's Stripe Planar HEXFET® process to achieve low on-resistance per silicon area while maintaining ruggedness against unclamped inductive switching. Its body diode supports fast recovery (t_rr = 100–150 ns) and high di/dt (290 A/μs), enabling use in synchronous rectification and bidirectional power stages.

The device operates across –55°C to +175°C with thermal resistance R_θJC = 1.4°C/W and R_θJA = 50°C/W (PCB-mounted), and features a fixed gate threshold voltage range of 2.0–4.0 V and transconductance g_fs = 27 S-supporting robust gate drive design in noisy automotive environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	75 V - Maximum blocking voltage for 12 V/24 V automotive battery rail protection and load switching.
R_DS(on) typ.	21.8 mΩ @ V_GS = 10 V, I_D = 25 A - Enables <1 W conduction loss at 25 A, critical for thermally constrained under-hood modules.
I_D (cont.)	42 A @ T_C = 25°C - Supports high-current solenoid drivers and BLDC phase switches without forced cooling.
E_AS	130 mJ - Single-pulse avalanche energy rating ensures survivability during inductive turn-off transients in motor drives.
Q_g	74 nC typ. - Reduces gate drive power and enables efficient operation with standard 1 A gate drivers at >100 kHz switching.
t_r/t_f	90 ns / 66 ns - Fast switching minimizes overlap losses in hard-switched SMPS and half-bridge inverters.
dV/dt	5.0 V/ns - Confirmed dynamic dv/dt immunity prevents spurious turn-on in high-noise engine bay environments.

Pinout & Package

Supplied in D-Pak (TO-252AA) package with exposed drain pad for thermal enhancement and mechanical robustness in automotive vibration environments.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	Main current path output terminal	Internally connected to exposed copper pad; primary heat transfer path to PCB ground plane.
Source (S)	Reference node for gate drive and current sensing	Low-inductance source connection (L_S = 7.5 nH); critical for stable high-speed switching and accurate current monitoring.
Gate (G)	Control input for channel conduction	High-impedance CMOS-compatible input requiring <200 nA leakage at ±20 V; sensitive to ESD but hardened per AEC-Q101.

Key Features

Feature	Design Value
Fully avalanche rated	Single-pulse E_AS = 130 mJ and repetitive E_AR = 11 mJ enable reliable operation in unclamped inductive loads without external snubbers.
175°C operating junction temperature	Supports placement near heat sources (e.g., exhaust manifolds, powertrain ECUs) without derating in engine control units.
Dynamic dV/dt rating	5.0 V/ns immunity verified per Fig. 14 test circuit-prevents false triggering during high-slew-rate transients in starter generators.
Low R_DS(on) × Q_g figure-of-merit	21.8 mΩ × 74 nC = 1.61 nΩ·F - balances conduction and switching losses for optimal efficiency in 20–200 kHz automotive SMPS.
AEC-Q101 qualified	Validated for automotive applications including engine control, transmission control, and ADAS power supplies per Infineon qualification standards.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N4LF6AG	60 V V_DS, 1.8 mΩ R_DS(on), PowerFLAT 5x6 package, lower R_DS(on) but reduced voltage rating	Better suited for 48 V systems only; not rated for 75 V transients in 12 V/24 V battery rails	Select when system max V_DS ≤ 60 V and ultra-low conduction loss is prioritized over transient robustness.
IRF3205PbF	55 V V_DS, 8.0 mΩ R_DS(on), TO-220 package, no AEC-Q101 qualification, higher R_θJA = 62°C/W	Non-automotive grade; unsuitable for under-hood deployment due to temperature and reliability limitations	Acceptable only for non-safety-critical 12 V bench prototypes-not for production automotive use.

Compared with STL220N4LF6AG and IRF3205PbF, AUIRFR2407 uniquely delivers 75 V rating, AEC-Q101 qualification, and 175°C operation-making it the only viable choice for production 12 V/24 V automotive power switching where transient immunity and long-term reliability are mandatory.

FAQ

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

The AUIRFR2407 supports 29 A continuous drain current at T_C = 100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits of the D-Pak package and silicon, and must be applied in conjunction with R_θJC = 1.4°C/W to calculate actual junction temperature under real operating conditions.

Is the body diode suitable for synchronous rectification?

Yes-the integral p-n junction body diode has t_rr = 100–150 ns and Q_rr = 400–600 nC at I_F = 25 A, enabling use in synchronous rectification topologies up to ~150 kHz. However, external Schottky diodes remain preferred for >200 kHz operation due to lower Q_rr.

Does AUIRFR2407 require a gate resistor for automotive EMI compliance?

A gate resistor of 6.8 Ω is used in the official switching time test circuit (Fig. 10a) and yields measured t_d(off) = 65 ns and t_f = 66 ns. This value balances EMI suppression and switching loss; values <4.7 Ω may increase radiated emissions, while >15 Ω degrades efficiency in high-frequency operation.

Can AUIRFR2407 replace IRFR2407 in existing designs?

Yes-AUIRFR2407 is the automotive-qualified (AEC-Q101) version of IRFR2407, sharing identical pinout, package, and electrical specifications. The "AU" prefix denotes automotive qualification, including extended temperature range (–55°C to +175°C), enhanced reliability testing, and traceable lot control per IATF 16949.
