Product details

Overview

AUIRFS3004-7P from Infineon is an automotive-grade N-channel D2Pak-7 pin HEXFET® Power MOSFET with 40 V V_DS, 0.90 mΩ typ. R_DS(on) at V_GS = 10 V, 240 A package-limited continuous drain current, and 175 °C maximum junction temperature - deployed in high-current DC-DC converters and 48 V automotive power distribution systems.

For engineers reviewing the AUIRFS3004-7P datasheet, AUIRFS3004-7P pinout, AUIRFS3004-7P application, or AUIRFS3004-7P equivalent, key selection criteria include silicon- vs. package-limited current rating (400 A vs. 240 A), unclamped inductive avalanche capability (290 mJ single-pulse), thermal resistance (R_θJC = 0.40 °C/W), and automotive qualification per AEC-Q101.

Technical Context

This device employs advanced trench-gate process technology to achieve ultra-low on-resistance while maintaining robust switching performance: total gate charge is 160–240 nC, turn-off delay is 91 ns, and diode reverse recovery time is 49–51 ns across temperature. Its body diode supports synchronous rectification with V_SD ≤ 1.3 V at 195 A and I_RRM ≤ 3.2 A.

The MOSFET is rated for repetitive avalanche operation up to T_jmax, with E_AR = 240 mJ at 1% duty cycle and I_AS = 240 A. Thermal design relies on low R_θJC (0.40 °C/W) and linear derating (2.5 W/°C above 25 °C case temperature), validated under board-mounted still-air conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage for 48 V automotive bus and industrial DC-DC primary-side switching.
R_DS(on) typ.	0.90 mΩ at V_GS = 10 V, I_D = 195 A - Enables <1.8 W conduction loss at 150 A, critical for high-efficiency power stages.
I_D (Package)	240 A continuous at T_C = 25 °C - Limited by bond wire and leadframe thermal capacity, not silicon.
E_AS	290 mJ single-pulse avalanche energy - Supports unclamped inductive switching in motor drives and solenoid control without external snubbers.
R_θJC	0.40 °C/W - Enables direct heatsink mounting with minimal thermal interface resistance for high-power density layouts.
Q_g	160–240 nC - Determines gate driver current requirement (≥3 A peak) for <100 ns switching transitions at 240 A load.
T_J max	+175 °C - Required for under-hood automotive applications including engine control modules and battery disconnect units.

Pinout & Package

D2Pak-7 pin package with exposed drain pad (pins 1–3 and 5–7 are source terminals; pin 4 is gate; drain connected to backside metal tab). Mounting requires soldered thermal pad for R_θJC compliance.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 5, 6, 7	Source	Parallel source connections reduce package inductance and improve current sharing in high-di/dt applications.
4	Gate	Single gate input with 2.0 Ω typical gate resistance - compatible with standard 12 V gate drivers without external series resistance.
Drain (Tab)	Drain	Exposed copper drain pad enables low-inductance, high-current path to heatsink; must be electrically isolated and thermally coupled.

Key Features

Feature	Design Value
Ultra-low R_DS(on)	0.90 mΩ typ. reduces conduction losses by >30% versus prior-gen 40 V MOSFETs in 200 A+ power stages.
175 °C operating temperature	Enables placement in high-ambient zones (e.g., near engines or inverters) without derating for junction temperature.
Repetitive avalanche rated	Validated for repeated unclamped inductive switching up to 240 A, eliminating need for external clamping diodes in motor phase legs.
Automotive qualification	AEC-Q101 qualified with full traceability, enabling use in safety-critical ADAS power supplies and EV battery management systems.
Fast body diode recovery	t_rr = 49 ns at 25 °C ensures minimal cross-conduction loss during synchronous rectification in buck converters.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current 40 V power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N4F7AG	R_DS(on) = 0.75 mΩ (lower), but T_Jmax = 175 °C and Q_g = 270 nC (higher); no AEC-Q101 certification.	Not qualified for automotive safety-critical systems; suitable only for industrial motor drives where qualification is waived.	Select only if lower conduction loss outweighs gate drive overhead and automotive compliance is unnecessary.
IRFB4115PBF	R_DS(on) = 1.5 mΩ (higher), T_Jmax = 175 °C, E_AS = 190 mJ (lower); TO-220FP package, R_θJC = 1.2 °C/W.	Limited to <120 A continuous due to thermal constraints; unsuitable for 240 A automotive power distribution.	Use only in cost-sensitive, lower-current (<100 A) industrial SMPS where thermal margin is available.

Compared with STL220N4F7AG and IRFB4115PBF, AUIRFS3004-7P uniquely balances ultra-low R_DS(on), AEC-Q101 qualification, and 240 A package-limited current in a thermally optimized D2Pak-7 package - making it the only viable choice for production 48 V automotive power switches requiring both reliability and power density.

FAQ

What is the maximum continuous drain current for AUIRFS3004-7P at 100 °C case temperature?

The maximum continuous drain current at T_C = 100 °C is 280 A (silicon-limited) and 240 A (package-limited). The lower value governs design - 240 A - because bond wire and leadframe thermal limits constrain sustained current regardless of junction temperature margin. This is confirmed in the Absolute Maximum Ratings table under "ID @ TC = 100°C".

Is AUIRFS3004-7P suitable for synchronous rectification in a 48 V buck converter?

Yes. Its body diode has V_SD ≤ 1.3 V at 195 A and t_rr = 49 ns at 25 °C, enabling efficient synchronous rectification. Gate threshold voltage (2.0–4.0 V) and low Q_gd/Q_g ratio (65/240 nC) support clean turn-on/turn-off timing with standard 12 V gate drivers, minimizing shoot-through risk in high-frequency (>200 kHz) VRMs.

Does AUIRFS3004-7P require a heatsink when operating at 240 A continuous?

Yes. At 240 A and 0.90 mΩ R_DS(on), conduction loss is ~52 W. With R_θJC = 0.40 °C/W and ambient at 85 °C, a heatsink with R_θSA ≤ 0.8 °C/W is required to maintain T_J ≤ 175 °C. The D2Pak-7 drain tab must be soldered to a thermally robust copper plane or external heatsink using recommended footprint AN-994.

How does the 7-pin D2Pak package improve performance over standard 3-pin TO-263?

The D2Pak-7 provides six parallel source terminals (pins 1–3, 5–7) and one gate (pin 4), reducing source loop inductance by ~40% and enabling cleaner high-di/dt switching. Combined with the large exposed drain tab, it achieves R_θJC = 0.40 °C/W - 67% lower than TO-263's typical 1.2 °C/W - directly improving thermal headroom in space-constrained automotive modules.
