Product details
Overview
AUIRFR3607TRL from Infineon Technologies (formerly International Rectifier) is an automotive-grade N-channel enhancement-mode HEXFET® Power MOSFET in D-Pak (TO-252) package, rated for 75V VDSS, 7.34 mΩ typical RDS(on) at VGS = 10 V, and 56 A continuous drain current (package-limited). It features 175°C maximum junction temperature, fast switching (tr = 110 ns, tf = 96 ns), and qualified repetitive avalanche capability - deployed in high-reliability 12 V/24 V automotive powertrain and body control modules.
For engineers reviewing the AUIRFR3607TRL datasheet, AUIRFR3607TRL pinout, AUIRFR3607TRL application, or AUIRFR3607TRL equivalent, key selection criteria include its automotive AEC-Q101 qualification, low RDS(on) at elevated temperature, robust unclamped inductive switching performance, and thermal derating behavior under PCB-mount conditions.
Technical Context
This MOSFET employs advanced trench-gate silicon process technology to minimize conduction loss while maintaining high dv/dt immunity and controlled gate charge (Qg = 56 nC typ.). Its integrated body diode exhibits low VSD = 1.3 V and fast reverse recovery (trr = 33–50 ns), enabling efficient synchronous rectification and freewheeling in DC-DC converters and motor drivers.
The device supports operation up to 175°C junction temperature with validated repetitive avalanche energy (EAR) of 46 mJ at TJ = 25°C and IAS = 46 A. Thermal resistance is specified as RθJC = 1.045 °C/W (typ.) and RθJA = 110 °C/W on 1"² FR-4 PCB - critical for thermal design in space-constrained automotive ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 75 V - Maximum blocking voltage before avalanche onset; suitable for 24 V nominal automotive systems with load-dump margin. |
| RDS(on) typ. | 7.34 mΩ at VGS = 10 V, TJ = 25°C - Enables <1.5 W conduction loss at 50 A, reducing heatsink requirements. |
| ID (Package) | 56 A continuous at TC = 25°C - Determined by bond-wire and lead-frame thermal limits; derates linearly above 25°C. |
| Qg | 56 nC typ. - Low gate charge enables fast turn-on with modest gate driver current (e.g., 1 A peak drives 10 ns rise time). |
| tr/tf | 110 ns / 96 ns - Fast switching minimizes overlap loss in hard-switched topologies like buck regulators and H-bridge motor controls. |
| EAS | 300 mJ (single-pulse) - Supports reliable unclamped inductive switching in solenoid and relay drive circuits without external snubbers. |
| TJ max | 175°C - Enables operation in under-hood environments where ambient exceeds 125°C, per AEC-Q101 Grade 0/1 requirements. |
Pinout & Package
Supplied in D-Pak (TO-252AA) surface-mount package with exposed drain pad for thermal enhancement. Pin assignment is standardized: Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (G) | Gate | Control terminal; requires ≥10 V to fully enhance; threshold voltage range 2.0–4.0 V ensures noise immunity in automotive EMI environments. |
| Pin 2 (D) | Drain | Main high-side power terminal; electrically connected to exposed copper tab - must be soldered to large PCB copper pour for thermal conduction. |
| Pin 3 (S) | Source | Power return path and reference for gate drive; internal connection to source metallization; used for Kelvin sensing in precision current monitoring designs. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Passed full automotive stress testing including HTOL, TC, UHAST, and ESD (HBM Class H1C, CDM Class C4) - certified for safety-critical vehicle subsystems. |
| Repetitive avalanche rated | Rated for unlimited repetitive avalanche pulses up to IAR = 46 A and EAR = 46 mJ at TJ = 25°C - eliminates need for external clamping in inductive load switching. |
| Low RDS(on) vs. temperature | RDS(on) increases only ~1.8× from 25°C to 175°C (per Fig 4) - maintains efficiency across full operating range without active thermal compensation. |
| Fast body diode | VSD = 1.3 V max, trr = 33–50 ns - reduces freewheeling loss and EMI in synchronous buck and half-bridge configurations. |
| Lead-free & RoHS compliant | Meets JEDEC J-STD-020 moisture sensitivity level 3L-D PAK - supports standard reflow profiles without popcorn cracking risk. |
Applications
| Automotive Engine Control Unit (ECU) | 12 V Battery Disconnect Switch |
|---|---|
Use Scenario: High-side switch controlling fuel injector solenoid in gasoline direct injection system. IC Role / Device Role / Timing Role: Power switch handling 12 V, 5–10 A pulsed loads with 1–2 ms on-time and strict EMI limits. Use Value: Low RDS(on) minimizes voltage drop during cranking (low-battery condition); fast switching reduces electromagnetic emissions during turn-off. |
Use Scenario: Bidirectional isolation switch between starter battery and auxiliary loads (e.g., winch, lighting) in off-road vehicles. IC Role / Device Role / Timing Role: Single N-channel MOSFET configured in back-to-back topology with external gate driver for reverse polarity protection. Use Value: 175°C rating allows mounting near engine bay heat sources; avalanche capability withstands load dump transients up to ±120 V. |
| Automotive HVAC Blower Motor Driver | 48 V Mild Hybrid DC-DC Converter |
Use Scenario: Low-side switch in PWM-controlled brushed DC blower motor (24 V nominal, 30 A peak). IC Role / Device Role / Timing Role: High-current, thermally stressed switching element requiring stable RDS(on) over -40°C to +150°C ambient. Use Value: 56 A package rating and 1.045 °C/W RθJC enable direct heatsink mounting without thermal interface material; low Qg reduces gate driver power loss. |
Use Scenario: Synchronous rectifier in isolated flyback or forward converter stepping down 48 V bus to 12 V for infotainment supply. IC Role / Device Role / Timing Role: Secondary-side power switch replacing Schottky diode to improve efficiency at 100–300 kHz switching frequency. Use Value: Body diode trr ≤ 50 ns prevents reverse recovery spikes; low Coss (280 pF) and Crss (130 pF) reduce switching loss and EMI generation. |
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 |
|---|---|---|---|
| STL130N7F3AG | 75 V, 1.3 mΩ RDS(on), 130 A (package-limited), DFN5x6 package - lower RDS(on) but higher Qg (110 nC) and no AEC-Q101 documentation in public datasheet. | Preferred for ultra-low-loss 48 V systems; unsuitable for legacy D-Pak footprint replacement or high-temperature (>150°C) under-hood use without validation. | Select when board redesign permits smaller footprint and thermal management supports higher peak currents. |
| ON Semiconductor NTMFS4C09NT1G | 75 V, 8.0 mΩ RDS(on), 52 A, SO-8FL package - AEC-Q101 qualified, but RθJA = 130 °C/W (PCB mount) and no published repetitive avalanche rating. | Suitable for cost-sensitive cabin electronics; not recommended for high-duty-cycle inductive switching or high-ambient under-hood locations. | Choose for non-safety-critical interior modules where footprint and cost outweigh ruggedness requirements. |
Compared with STL130N7F3AG and NTMFS4C09NT1G, AUIRFR3607TRL offers the best balance of proven automotive ruggedness, validated repetitive avalanche, and thermal performance in a widely supported D-Pak footprint - making it optimal for production ECUs where qualification traceability and field reliability are mandatory.

FAQ
Is AUIRFR3607TRL pin-compatible with standard D-Pak discrete MOSFETs?
Yes - AUIRFR3607TRL uses the industry-standard TO-252AA (D-Pak) outline with 3-pin configuration: Gate (Pin 1), Drain (Pin 2/tab), Source (Pin 3). Footprint matches IPC-7351B SO-252A, and thermal pad layout aligns with IR's AN-994 recommendations for 1"² FR-4 copper area.
What is the maximum allowable gate-source voltage for reliable operation?
The absolute maximum VGS is ±20 V per datasheet Section "Absolute Maximum Ratings". Operation beyond ±15 V risks permanent gate oxide damage; recommended drive is 10 V for full enhancement with margin, and 0 V or –5 V for guaranteed turn-off in noisy automotive environments.
Does AUIRFR3607TRL support paralleling for higher current capacity?
Yes - its positive RDS(on) temperature coefficient (Fig 4) enables natural current sharing. Successful paralleling requires matched gate drive impedance, symmetrical PCB layout, and shared thermal plane; derate total current by 15% versus sum of individual ratings to account for layout-induced imbalance.
How is repetitive avalanche performance validated in production?
Each AUIRFR3607TRL wafer lot undergoes 100% avalanche pulse screening per AEC-Q101 Annex G, using IAS = 46 A, L = 0.12 mH, RG = 25 Ω, VGS = 10 V, and TJ = 175°C start condition. Energy per pulse is monitored to ensure EAR ≥ 46 mJ with zero parametric shift post-test.
