Product details
Overview
AUIRF1404STRL from Infineon Technologies is an automotive-grade N-channel HEXFET® Power MOSFET in TO-220AB package, rated for 40 V V(BR)DSS, 3.5 mΩ typical RDS(on), 202 A continuous drain current (silicon-limited), and qualified to AEC-Q101. It serves as a high-current, low-loss main switch in 12 V automotive power distribution systems including starter solenoid control and battery disconnect circuits.
For engineers reviewing the AUIRF1404STRL datasheet, AUIRF1404STRL pinout, AUIRF1404STRL application, or AUIRF1404STRL equivalent, key selection criteria include its 40 V breakdown voltage, sub-4 mΩ on-resistance at 10 V gate drive, 160 A package-limited current, robust unclamped inductive switching capability (EAS = 202 mJ), and AEC-Q101 qualification for under-hood use.
Technical Context
This MOSFET employs planar vertical DMOS technology optimized for low conduction loss and fast switching in DC-DC converters and motor drives. Its gate charge profile (Qg = 131–196 nC, Qgd = 37–56 nC) supports efficient hard-switching up to ~100 kHz with moderate gate driver strength.
The integrated body diode exhibits trr = 78–117 ns and Qrr = 163–245 nC, enabling synchronous rectification in buck topologies. Thermal design is anchored by RθJC = 0.45 °C/W and RθJA = 62 °C/W (board-mounted, still air), supporting high-power operation with heatsink mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 40 V - Withstands up to 40 V drain-source blocking voltage before avalanche onset; suitable for 12 V automotive systems with load dump margins. |
| RDS(on) typ. | 3.5 mΩ @ VGS = 10 V, TJ = 25°C - Delivers ≤0.7 W conduction loss at 121 A, enabling high-efficiency power switching. |
| ID (Silicon Limited) | 202 A @ TC = 25°C - Maximum continuous current determined by silicon thermal limits, not package constraints. |
| EAS | 202 mJ - Single-pulse avalanche energy rating confirms ruggedness against inductive turn-off transients in solenoid or motor control. |
| Qg / Qgd | 131–196 nC / 37–56 nC - Gate charge values define driver sizing and switching loss trade-offs in PWM applications. |
| RθJC | 0.45 °C/W - Enables direct heatsink mounting with predictable junction-to-case thermal path for thermal management. |
| trr / Qrr | 78–117 ns / 163–245 nC - Body diode recovery characteristics support use in freewheeling paths without external Schottky supplementation. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (Metal Surface) | Drain (D) | Electrically connected to drain; requires insulating washer if mounted to grounded heatsink. |
| Lead 1 (Left) | Source (S) | Main current return path; low-inductance connection critical for minimizing switching noise. |
| Lead 2 (Center) | Gate (G) | High-impedance control terminal; requires low-impedance gate driver and layout to suppress ringing. |

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 |
|---|---|---|---|
| STL220N4F7AG | 40 V, 220 A, RDS(on) = 2.8 mΩ typ., DFN8 5×6 mm package | Surface-mount only; no through-hole option; higher current but lower thermal mass | Select for space-constrained PCBs where TO-220 footprint is unavailable and thermal interface is optimized. |
| IRF1404ZPBF | 40 V, 202 A, RDS(on) = 3.8 mΩ max., TO-220AB, non-automotive grade | Lacks AEC-Q101 qualification; lower ESD robustness (HBM ±2 kV vs ±4 kV) | Acceptable for industrial or consumer 12 V power switches where automotive reliability is not mandated. |
Compared with STL220N4F7AG and IRF1404ZPBF, AUIRF1404STRL uniquely combines AEC-Q101 qualification, TO-220AB through-hole compatibility, and 3.5 mΩ on-resistance-making it optimal for production automotive modules requiring field-proven ruggedness and serviceability.

FAQ
Is AUIRF1404STRL RoHS compliant and lead-free?
Yes, AUIRF1404STRL is RoHS compliant and lead-free per EU Directive 2011/65/EU. The device uses matte tin plating on leads and meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 requirements for unlimited floor life at ≤30°C/60% RH.
What is the maximum safe operating frequency for AUIRF1404STRL in hard-switched applications?
AUIRF1404STRL supports hard-switched operation up to approximately 100 kHz when driven with a 2.5 Ω gate resistor and 121 A load, based on measured td(on)/td(off) ≤ 63 ns total delay and tr/tf ≤ 220 ns combined transition time. Higher frequencies require optimized gate drive and layout to manage switching losses.
Can AUIRF1404STRL be used in parallel configurations?
Yes, AUIRF1404STRL supports paralleling due to its positive RDS(on) temperature coefficient (0.039 V/°C dV(BR)DSS/dTJ), which promotes current sharing. Use matched gate resistors, symmetrical PCB layout, and individual source inductance minimization to ensure balanced dynamic current distribution.
Does the body diode support continuous bidirectional current flow?
No-the integrated body diode is unidirectional (source-to-drain) and rated for IS = 202 A continuous and ISM = 808 A pulsed. It is not designed for sustained reverse conduction; use external diodes or complementary MOSFETs for true bidirectional power flow.
