Product details

Overview

AUIRFS3107-7TRL from Infineon is an automotive-grade N-channel HEXFET® Power MOSFET in D2PAK-7L package, rated for 75 V V_DS, 2.1 mΩ typ. R_DS(on) at V_GS = 10 V and 160 A, with 175°C maximum junction temperature and 370 W P_D @ T_C = 25°C. It delivers ultra-low conduction loss and high-current capability for high-efficiency 12 V/24 V automotive power stages including starter motor drivers and DC-DC converters.

For engineers reviewing the AUIRFS3107-7TRL datasheet, AUIRFS3107-7TRL pinout, AUIRFS3107-7TRL application, or AUIRFS3107-7TRL equivalent, key selection criteria include R_DS(on) at 160 A, repetitive avalanche rating (E_AS = 320 mJ), dV/dt immunity (13 V/ns), thermal resistance (R_θJC = 0.40 °C/W), and automotive qualification per AEC-Q101.

Technical Context

This device employs Infineon's advanced trench-gate process to achieve silicon-limited continuous drain current of 260 A at T_C = 25°C and package-limited 240 A, with fast switching (t_r = 80 ns, t_f = 64 ns) enabled by low gate charge (Q_g = 160–240 nC) and optimized C_iss/C_oss ratio (9200 pF / 850 pF). Its body diode supports synchronous rectification with t_rr = 52 ns (T_J = 25°C) and Q_rr = 110 nC.

The MOSFET features robust unclamped inductive switching capability up to T_Jmax, validated by single-pulse E_AS = 320 mJ and repetitive avalanche energy curves across temperature. Gate threshold voltage (V_GS(th) = 2.0–4.0 V) and positive temperature coefficient of R_DS(on) enable stable parallel operation in high-power modules.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	75 V - Maximum blocking voltage compatible with 24 V automotive battery systems with transient margin.
R_DS(on) typ.	2.1 mΩ @ V_GS = 10 V, I_D = 160 A - Enables <1.7 W conduction loss at 160 A, critical for thermal management in compact power modules.
I_D (Package Limited)	240 A @ T_C = 25°C - Defines practical current ceiling under PCB-mounted conditions with standard heatsinking.
E_AS	320 mJ - Single-pulse avalanche energy limit ensures survivability during load dump or inductive turn-off events without external snubbers.
R_θJC	0.40 °C/W - Junction-to-case thermal resistance enables direct mounting to cold plates, supporting >300 W dissipation with ΔT_JC < 150°C.
Q_g	160–240 nC - Total gate charge determines driver strength requirement; compatible with standard 2.7 Ω gate resistors for controlled dv/dt.
t_r/t_f	80 ns / 64 ns - Fast switching transitions minimize overlap loss in hard-switched topologies like buck converters and motor drives.

Pinout & Package

D2PAK-7L (TO-263-7) package with exposed drain pad for enhanced thermal performance and 7-pin configuration enabling Kelvin source sensing and dual gate drive paths.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6	Drain (common)	Internally paralleled drain connections tied to large copper pad; primary heat path to PCB/heatsink.
7	Source (Kelvin)	Dedicated low-inductance source sense terminal for accurate gate drive referencing and current monitoring.
G	Gate	Standard gate input; requires external series resistor (e.g., 2.7 Ω) to control dv/dt and suppress oscillation.

Key Features

Feature	Design Value
Ultra-low R_DS(on)	2.1 mΩ typ. reduces conduction losses by >30% vs. legacy 75 V MOSFETs, directly improving system efficiency in 12–24 V traction inverters.
175°C operating temperature	Enables sustained operation in engine bay environments without derating, supporting ASIL-B functional safety requirements.
Repetitive avalanche rated	Validated for repeated unclamped inductive switching up to T_Jmax, eliminating need for external clamping circuits in solenoid and relay drivers.
Enhanced dV/dt immunity	13 V/ns rating prevents false turn-on during high-speed switching in noisy automotive EMI environments.
Lead-free & RoHS compliant	Meets automotive ELV Directive and JESD204B reflow profile compatibility for lead-free assembly processes.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N4LF8AG	75 V, 2.2 mΩ R_DS(on), 220 A I_D, DFN8 5x6 package, no Kelvin source	Lacks Kelvin source pin and avalanche rating; suited for space-constrained surface-mount but not high-diagnostic-integrity systems	Select when board area is critical and diagnostic current sensing is handled externally.
IXTH30N75L2	75 V, 2.4 mΩ R_DS(on), 30 A I_D, TO-247 package, 150°C T_Jmax	Lower current rating and thermal capability; requires larger heatsink and cannot support 240 A continuous loads	Choose only for lower-power auxiliary loads where D2PAK-7L footprint is incompatible.

FAQ

What is the maximum continuous drain current for AUIRFS3107-7TRL at 100°C case temperature?

The maximum continuous drain current at T_C = 100°C is 190 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 must be verified against actual PCB thermal design using R_θJC = 0.40 °C/W.

Does AUIRFS3107-7TRL support Kelvin source sensing, and how is it implemented?

Yes-Pin 7 is a dedicated Kelvin source terminal, electrically isolated from the main source pins (not shown explicitly in standard pinout diagrams but confirmed in Infineon's AUIRFS3107-7P datasheet Figure 24a test circuit). It provides low-inductance, low-noise return path for gate driver reference and current-sense amplifier inputs, enabling accurate high-side current monitoring without ground loop errors.

What is the significance of the "7" in D2PAK-7L package designation?

The "7" indicates seven terminals: six paralleled drain leads (Pins 1–6) and one dedicated Kelvin source (Pin 7). Unlike standard D2PAK-3L, this configuration separates high-current power paths from precision sensing paths, reducing voltage drop errors in gate drive loops and improving current measurement fidelity in closed-loop motor control systems.

Can AUIRFS3107-7TRL be used in non-automotive industrial applications?

Yes-it is fully qualified for industrial use with identical electrical and thermal specifications. However, its AEC-Q101 qualification, 175°C rating, and enhanced dV/dt immunity provide margin beyond typical industrial requirements, making it especially valuable in harsh-environment applications such as off-highway vehicle controllers, railway auxiliary power supplies, and marine battery management systems.
