Product details

Overview

AUIRFS8407-7TRL from Infineon Technologies (formerly International Rectifier) is an automotive-grade N-channel HEXFET® Power MOSFET in D2PAK-7L package, rated for 40 V V_DS, 1.0 mΩ typ. R_DS(on) at V_GS = 10 V, and 240 A continuous drain current (package-limited). It delivers ultra-low conduction loss, 175°C junction operation, and robust repetitive avalanche capability-designed for high-current battery switching and electric power steering systems.

For engineers reviewing the AUIRFS8407-7TRL datasheet, AUIRFS8407-7TRL pinout, AUIRFS8407-7TRL application, or AUIRFS8407-7TRL equivalent, this part is selected for demanding automotive power stages where thermal resilience, fast switching (t_r = 62 ns), and body diode recovery (t_rr = 37 ns at T_J = 25°C) are critical to system efficiency and reliability.

Technical Context

This MOSFET employs advanced silicon processing to achieve sub-1.3 mΩ maximum on-resistance with optimized gate charge (Q_g = 150–225 nC) and low C_oss (1097 pF typ.), enabling high-frequency DC-DC conversion and PWM motor control. Its integrated body diode supports synchronous rectification and unclamped inductive switching.

The device features a thermally enhanced D2PAK-7L package with three source pins and dual drain tabs, delivering R_θJC = 0.65°C/W and supporting >1040 W peak power dissipation at T_C = 25°C. Avalanche energy rating is validated up to 344 mJ (single-pulse, T_J = 25°C) and 231 mJ (repetitive, T_J = 175°C).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage for 12 V/24 V automotive battery rail protection and EPS H-bridge switches.
R_DS(on) typ.	1.0 mΩ @ V_GS = 10 V - Enables <1.0 W conduction loss at 100 A, critical for thermal management in compact modules.
I_D (package)	240 A continuous - Determined by lead-frame current capacity, not silicon limit; defines PCB trace and busbar sizing.
Q_g	150–225 nC - Gate drive energy requirement directly impacts driver IC selection and switching loss at 10–100 kHz.
t_r/t_f	62 ns / 51 ns - Fast edge rates reduce transition losses but require careful layout to suppress EMI in high-di/dt applications.
E_AS (tested)	344 mJ - Validated single-pulse avalanche energy ensures survivability during load dump or inductive kick events.
T_J max	175°C - Enables operation in under-hood environments without derating below ambient +150°C.

Pinout & Package

D2PAK-7L (TO-263-7) package with exposed drain thermal pad, 3× source terminals (S1/S2/S3), 1× gate (G), and 2× drain connections (D1/D2) for parallel current paths and low-inductance mounting.

Pin/Terminal	Circuit Role	Design Meaning
G	Gate	Control input requiring 10 V threshold; low R_G (2.2 Ω typ.) enables fast turn-on with minimal external gate resistor.
S1, S2, S3	Source	Three paralleled source terminals reduce source inductance and improve current sharing in high-di/dt switching.
D1, D2	Drain	Dual drain pads provide low-inductance, high-current return path and enhance thermal coupling to heatsink.
Thermal Pad	Drain (internally connected)	Exposed copper pad must be soldered to PCB ground plane or heatsink; primary thermal path (R_θJC = 0.65°C/W).

Key Features

Feature	Design Value
Ultra-low R_DS(on)	1.0 mΩ typ. at 100 A - Reduces I²R losses by >40% vs. legacy 2.0 mΩ automotive MOSFETs, lowering thermal design burden.
Repetitive avalanche rating	231 mJ at T_J = 175°C - Enables reliable operation in unclamped inductive loads (e.g., solenoid drivers) without external snubbers.
Fast body diode recovery	t_rr = 37 ns, Q_rr = 34 nC at T_J = 25°C - Minimizes reverse recovery loss and EMI in synchronous rectifier and bidirectional DC-DC topologies.
Automotive qualification	AEC-Q101 qualified - Validated for temperature cycling, humidity, and mechanical shock per automotive reliability standards.
Lead-free & RoHS compliant	Halogen-free, Pb-free terminations - Meets EU ELV and OEM chemical compliance requirements for vehicle production.

Applications

IC Role / Device Role / Timing Role: Main power switch handling bidirectional 200+ A peak currents with <100 ns switching transitions.

Use Value: Low R_DS(on) and fast t_r/t_f minimize heat generation during frequent direction reversals, extending module lifetime.

Use Scenario: Isolating high-voltage traction battery from vehicle chassis during crash or service disconnect events.

IC Role / Device Role / Timing Role: High-side or low-side main contactor replacement with controlled turn-on/off sequencing.

Use Value: 175°C operation and 344 mJ avalanche rating ensure fail-safe interruption of >200 A fault currents without thermal runaway.

Start-Stop Micro-Hybrid System

High-Power DC-DC Converter

Use Scenario: Controlling starter motor engagement and regenerative braking energy routing in 12 V/48 V dual-battery architectures.

IC Role / Device Role / Timing Role: Bidirectional power switch managing engine cranking pulses and brake energy recovery cycles.

Use Value: Repetitive avalanche capability absorbs inductive spikes from solenoid actuators and starter windings without degradation.

Use Scenario: Primary switch in 3–5 kW isolated DC-DC converters converting 48 V battery output to 12 V auxiliary supply.

IC Role / Device Role / Timing Role: High-frequency (50–100 kHz) synchronous rectifier or primary-side switch in phase-shifted full-bridge topology.

Use Value: Low C_oss (1097 pF) and Q_gd (51 nC) reduce switching losses and improve ZVS behavior at elevated frequencies.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N4F7AG	40 V, 220 A, R_DS(on) = 1.2 mΩ, DFN8 5×6 mm package	Lacks D2PAK-7L thermal mass and dual drain pads; lower I_D rating limits use in >200 A EPS designs.	Select when board space is constrained and thermal budget allows higher R_DS(on) penalty.
IPB011N04LGATMA1	40 V, 240 A, R_DS(on) = 1.1 mΩ, TO-263-7 package, no avalanche rating specified	No published E_AS or repetitive avalanche data; unsuitable for unclamped inductive loads without external protection.	Prefer only in clamped, low-dV/dt applications where avalanche stress is absent.

Compared with STL220N4F7AG and IPB011N04LGATMA1, AUIRFS8407-7TRL uniquely combines 1.0 mΩ on-resistance, 240 A package rating, and fully characterized 344 mJ avalanche performance-making it the only option qualified for direct replacement in safety-critical EPS and battery disconnect circuits without redesign.

FAQ

What is the maximum continuous drain current for AUIRFS8407-7TRL at 100°C case temperature?

The maximum continuous drain current at T_C = 100°C is 216 A (silicon-limited), as specified in the Absolute Maximum Ratings table. This value reflects thermal derating due to reduced channel conductivity and increased R_DS(on) at elevated temperatures, and assumes proper PCB copper area and heatsinking per AN-994 guidelines.

Does AUIRFS8407-7TRL support logic-level gate drive?

No-it requires 10 V gate drive for full enhancement, with V_GS(th) ranging from 2.2 V to 3.9 V. While it conducts partially at 5 V, R_DS(on) rises sharply above 2.5 mΩ, increasing conduction loss by >150%. A dedicated 10–12 V gate driver is mandatory for automotive-grade efficiency.

How is the D2PAK-7L package thermally optimized compared to standard D2PAK?

The D2PAK-7L adds two extra source pins and splits the drain connection across two pads, reducing source inductance by ~35% and improving thermal spreading from the die to the PCB. Its R_θJC of 0.65°C/W is 22% lower than standard D2PAK, enabling 25% higher power density in confined under-hood spaces.

Can AUIRFS8407-7TRL replace older IRFS8407 variants in existing designs?

Yes-AUIRFS8407-7TRL is a direct drop-in replacement for IRFS8407-7P/7TR with identical pinout, R_DS(on), and thermal specs. The "AU" prefix denotes AEC-Q101 qualification; all electrical parameters and packaging dimensions match, and no layout or driver changes are required for migration.
