Product details

Overview

AUIRFS3004-7TRL from Infineon is an automotive-grade N-channel D2Pak-7 power MOSFET optimized for high-current, low-loss switching in 12 V systems. It delivers 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 - enabling use in engine control units, battery disconnect switches, and high-power DC/DC converters.

For engineers reviewing the AUIRFS3004-7TRL datasheet, AUIRFS3004-7TRL pinout, AUIRFS3004-7TRL application, or AUIRFS3004-7TRL equivalent, key selection criteria include its ultra-low on-resistance, repetitive avalanche capability up to T_jmax, thermal robustness under high ambient conditions, and automotive qualification per AEC-Q101.

Technical Context

This HEXFET® device uses advanced silicon processing to achieve sub-1 mΩ on-resistance in a surface-mount D2Pak-7 package with integrated Kelvin source connection (Pin 7). Its gate charge profile (Q_g = 160–240 nC) and fast switching (t_r = 240 ns, t_f = 160 ns) support high-frequency synchronous rectification and PWM motor control.

The device integrates a robust body diode with 37 nC Q_rr, 49 ns t_rr, and 2.0 V/ns dv/dt rating, enabling reliable operation in hard-switched inductive loads. Thermal design is supported by R_θJC = 0.40 °C/W and 380 W P_D at T_C = 25 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage compatible with 12 V automotive battery systems including load dump transients.
R_DS(on) typ.	0.90 mΩ at V_GS = 10 V - 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 package thermal capacity, not silicon.
Q_g	160–240 nC - Determines gate drive power and switching speed; supports 100 kHz+ operation with moderate gate drivers.
E_AS	290 mJ single-pulse avalanche energy - Allows unclamped inductive switching without external snubbers in starter solenoid or fuel injector drivers.
T_J max	+175 °C - Enables operation in under-hood environments where ambient exceeds 125 °C.
Q_rr	37 nC at T_J = 25 °C - Low reverse recovery charge reduces switching losses and EMI in synchronous buck topologies.

Pinout & Package

D2Pak-7 (TO-263-7) surface-mount package with isolated tab (Drain), 6 signal pins + 1 Kelvin Source (Pin 7), designed for high-current PCB mounting and thermal transfer to copper planes.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6	Drain (common)	High-current power path connected to exposed metal tab; electrically tied to all six pins for lowest inductance and resistance.

G	Gate	Standard MOSFET gate input; requires 10 V for full enhancement; gate resistance R_G = 2.0 Ω typical.
S	Source	Main current return path; separate from Kelvin Source (Pin 7); used for power loop closure.

Key Features

Feature	Design Value
Ultra-low R_DS(on)	0.90 mΩ typ. enables <2 W conduction loss at 150 A, reducing heatsink requirements in space-constrained modules.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N4F7AG	40 V, 0.75 mΩ R_DS(on), DFN8 5×6 mm package, no Kelvin source, 175 °C rated.	Limited to lower-current PCB-mounted designs due to 120 A package limit and absence of Kelvin sensing.	Preferred for compact, low-inductance layouts where gate drive stability is less critical than footprint size.
IXFH400N04S4	40 V, 0.85 mΩ R_DS(on), TO-247-3L, 400 A silicon-limited I_D, no Kelvin source, 175 °C rated.	Requires through-hole mounting and larger heatsinking; higher gate charge (320 nC) slows switching vs. AUIRFS3004-7TRL.	Chosen when ultimate current capacity and serviceability outweigh surface-mount constraints and switching speed needs.

Compared with STL220N4F7AG and IXFH400N04S4, the AUIRFS3004-7TRL uniquely combines Kelvin Source precision, D2Pak-7 thermal performance (0.40 °C/W), and 240 A package-rated current - making it optimal for high-reliability, high-frequency automotive power stages where gate drive accuracy and thermal density are co-critical.

FAQ

What is the function of Pin 7 (Kelvin Source) on the AUIRFS3004-7TRL?

Pin 7 is a dedicated Kelvin Source terminal that provides a low-current, low-impedance reference path for the gate driver to measure true V_GS. It isolates gate control from high-current source path voltage drops, ensuring consistent turn-on behavior under dynamic load conditions - especially critical in high-side configurations and paralleled MOSFET designs.

Can the AUIRFS3004-7TRL be used in non-automotive applications?

Yes - while AEC-Q101 qualified and optimized for automotive thermal and reliability demands, its 40 V rating, 0.90 mΩ R_DS(on), and 175 °C operation make it suitable for industrial motor drives, server VRMs, and high-power LED drivers where high current density and thermal resilience are required.

How does the repetitive avalanche rating impact circuit design?

The device is rated for repetitive avalanche up to T_jmax = 175 °C, meaning it can safely absorb inductive energy (e.g., from motor windings or solenoids) multiple times without failure - provided junction temperature remains within limits. This eliminates mandatory external clamping circuits in many automotive inductive load drivers.

What is the maximum recommended gate resistor value for switching at 100 kHz?

With Q_g = 160–240 nC and typical gate drive voltage of 10–12 V, a gate resistor of 2.7 Ω (as used in datasheet test conditions) achieves ~91 ns t_d(off) and 160 ns t_f. For 100 kHz operation with <10% dead time, R_G ≤ 3.3 Ω is recommended to maintain efficient switching while avoiding excessive gate drive power dissipation.
