Product details
Overview
AUIRLR3410TR from Infineon Technologies is an automotive-grade N-channel enhancement-mode HEXFET® Power MOSFET in D-Pak (TO-252) package, rated for 100V V(BR)DSS, 17A continuous drain current at 25°C, and 105mΩ max RDS(on) at VGS = 10V. It features logic-level gate drive (VGS(th) = 1.0–2.0V), 175°C junction temperature rating, and full repetitive avalanche capability - deployed in DC-DC converters, motor control modules, and automotive body electronics.
For engineers reviewing the AUIRLR3410TR datasheet, AUIRLR3410TR pinout, AUIRLR3410TR application, or AUIRLR3410TR equivalent, key selection criteria include its low RDS(on) at 5V gate drive, robust dV/dt immunity (≥5.0 V/ns), integrated body diode with trr = 140–210 ns, and qualification to AEC-Q101 standards for under-hood use.
Technical Context
This MOSFET employs Infineon's Stripe Planar HEXFET architecture optimized for high-current density and thermal stability in automotive environments. Its dynamic dV/dT rating and fully avalanche-rated structure enable reliable operation in inductive switching circuits such as solenoid drivers and BLDC gate drivers without external snubbers.
The device integrates a fast-recovery body diode (Qrr = 740–1100 nC, trr = 140–210 ns) and exhibits low gate charge (Qg = 34 nC, Qgd = 20 nC), supporting efficient high-frequency PWM control up to 200 kHz in 12V/24V battery-fed systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 100 V - Withstands 100V drain-source blocking voltage before avalanche onset; suitable for 24V automotive systems with load-dump transients. |
| RDS(on) max | 105 mΩ @ VGS = 10V - Enables <1.8W conduction loss at 17A; reduces heatsink requirements in space-constrained modules. |
| ID @ TC = 25°C | 17 A - Continuous drain current rating under PCB-mount conditions; supports high-side switch designs in power distribution units. |
| EAS | 7.9 mJ - Single-pulse avalanche energy limit; allows safe unclamped inductive turn-off in relay/solenoid drivers. |
| Qg / Qgd | 34 nC / 20 nC - Gate charge profile enables predictable 5V logic-level switching with minimal driver IC loading. |
| trr / Qrr | 140–210 ns / 740–1100 nC - Body diode recovery performance supports synchronous rectification and freewheeling in buck converters. |
| TJ range | −55°C to +175°C - Qualified for engine bay and transmission control applications per AEC-Q101. |
Pinout & Package
Package: D-Pak (TO-252), surface-mount, single-die configuration with exposed drain pad for thermal conduction. Mounting requires FR-4 PCB with 1"² copper area per AN-994 guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G | Gate | Logic-level control input; threshold 1.0–2.0V; requires ≤34 nC total charge for full enhancement. |
| D | Drain | Main power output terminal; electrically connected to exposed backside metal pad for thermal and current path integrity. |
| S | Source | Reference node for gate drive and current sensing; internal source inductance LS = 7.5 nH affects high-di/dt ringing. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL100N10F7 | 100V, 100A, RDS(on) = 7.5mΩ @ 10V; TO-263 package; higher current, lower RDS(on), larger footprint | Targeted at high-power inverters; not drop-in due to different pinout and thermal interface | Select when >50A peak current and forced-air cooling are available. |
| IRLR8729PBF | 75V, 79A, RDS(on) = 5.8mΩ @ 10V; D-Pak; lower voltage rating, higher current, same footprint | Optimized for 12V starter systems; insufficient for 24V load-dump scenarios requiring 100V rating | Choose only for 12V-only applications where V(BR)DSS ≥ 85V is not required. |
Compared with STL100N10F7 and IRLR8729PBF, AUIRLR3410TR offers the optimal balance of 100V rating, D-Pak compatibility, and 17A/105mΩ performance for space-constrained automotive modules - making it preferred for ECU, body control, and lighting subsystems where voltage margin and thermal footprint are critical.

FAQ
Is AUIRLR3410TR suitable for 5V microcontroller gate drive?
Yes. With VGS(th) = 1.0–2.0V and full enhancement achievable at VGS = 4.0–5.0V (ID = 9.0A), it operates reliably with standard 5V GPIO outputs. Total gate charge is 34 nC, requiring ≤10 mA average drive current at 100 kHz PWM.
What is the maximum recommended PCB copper area for thermal performance?
Per Infineon Application Note AN-994, a minimum 1"² (6.45 cm²) FR-4 copper area with multiple thermal vias to inner ground planes is required to achieve RθJA = 50°C/W. Smaller pads increase junction temperature by up to 40°C at 17A.
Does AUIRLR3410TR have a specified dv/dt immunity rating?
Yes. The datasheet specifies a guaranteed minimum peak diode recovery dv/dt of 5.0 V/ns under test conditions (ISD ≤ 9.0A, di/dt ≤ 540 A/μs). This enables robust operation in high-di/dt inductive loads without parasitic turn-on.
Can AUIRLR3410TR replace older IRFR3410 in existing designs?
Yes - AUIRLR3410TR is the automotive-qualified, lead-free successor to IRFR3410. It shares identical D-Pak pinout, RDS(on), and gate characteristics but adds AEC-Q101 qualification, tighter VGS(th) distribution, and enhanced avalanche ruggedness for extended lifetime in automotive environments.
