Product details
Overview
AUIRF1404ZL from Infineon is an automotive-grade N-channel enhancement-mode HEXFET® Power MOSFET in TO-262 package, rated for 40 V VDS, 3.7 mΩ max RDS(on) at VGS = 10 V, and 160 A continuous drain current (package-limited), designed for high-efficiency DC-DC conversion and motor control in engine management and body electronics.
For engineers reviewing the AUIRF1404ZL datasheet, AUIRF1404ZL pinout, AUIRF1404ZL application, or AUIRF1404ZL equivalent, key selection criteria include its 175°C junction rating, 480 mJ tested single-pulse avalanche energy, fast 110 ns rise time, and RoHS-compliant lead-free construction under AEC-Q101 qualification.
Technical Context
This MOSFET employs advanced silicon processing to achieve ultra-low on-resistance per die area while maintaining robust unclamped inductive switching capability. Its gate charge profile (Qg = 100–150 nC) and low Ciss (4340 pF) support high-frequency PWM operation up to several hundred kHz in synchronous buck converters.
The device integrates a fast-recovery body diode with trr = 28–42 ns and Qrr = 34–51 nC, enabling efficient freewheeling in hard-switched topologies. Thermal design is enabled by RθJC = 0.75°C/W and validated repetitive avalanche performance up to TJmax = 175°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 40 V - Maximum blocking voltage for 12 V automotive systems with load-dump margin. |
| RDS(on) max | 3.7 mΩ @ VGS = 10 V - Enables <1.2 W conduction loss at 160 A, critical for high-current starter solenoid drivers. |
| ID (pkg-limited) | 160 A @ TC = 25°C - Sustains peak currents in electric power steering (EPS) H-bridge legs without derating. |
| EAS (tested) | 480 mJ - Confirmed avalanche energy supports reliable operation during inductive turn-off transients in fuel injector drivers. |
| tr / tf | 110 ns / 58 ns - Fast switching minimizes overlap losses in 200–500 kHz DC-DC controllers for ADAS camera modules. |
| TJ range | −55°C to +175°C - Validated operation across full automotive ambient range including under-hood environments. |
| Qg | 100–150 nC - Gate drive requirement compatible with standard 1 A peak gate drivers (e.g., IR2110, UCC27531). |
Pinout & Package
TO-262 (Straight Lead, 3-Pin) package with isolated tab; case connected to Drain. Mounting torque: 10 lbf·in (1.1 N·m) for M3 screw.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal (S) | Low-side reference node; connects to ground plane or current-sense shunt for overcurrent protection. |
| Pin 2 (Gate) | Control input (G) | High-impedance MOSFET gate requiring <150 nC charge; sensitive to ESD and layout-induced ringing. |
| Pin 3 (Drain) | Power output (D) | Internally bonded to metal tab; must be electrically isolated from heatsink unless system common-drain topology is used. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) | 3.7 mΩ max enables >97% efficiency in 12 V → 5 V/100 A buck converters at 250 kHz. |
| 175°C operating temperature | Supports placement near hot components (e.g., exhaust manifolds, inverters) without thermal derating. |
| Repetitive avalanche rated | Validated for repeated unclamped inductive switching up to TJmax, eliminating need for external snubbers in solenoid drivers. |
| Fast body diode recovery | trr = 28–42 ns and Qrr = 34–51 nC reduce cross-conduction loss and EMI in half-bridge motor drives. |
| AEC-Q101 qualified | Passed stress tests for automotive reliability: HTOL, TC, UHAST, ESD-HBM/MM, ensuring >15-year field life in safety-critical systems. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N4F7AG | 40 V, 2.2 mΩ typ RDS(on), DFN5x6 package, no isolated tab | Surface-mount only; unsuitable for through-hole heatsink mounting or high-current discrete designs | Select when board space is constrained and thermal interface uses soldered copper pads instead of mechanical screws. |
| IRF1404ZPBF | 40 V, 4.0 mΩ max RDS(on), TO-220AB package, non-automotive grade | Lacks AEC-Q101 qualification and 175°C rating; not approved for safety-critical automotive use | Acceptable only for non-automotive industrial prototypes where qualification testing is not required. |
Compared with STL220N4F7AG and IRF1404ZPBF, AUIRF1404ZL uniquely combines TO-262 mechanical robustness, AEC-Q101 qualification, 175°C operation, and 480 mJ tested avalanche energy-making it the only choice for production-grade automotive power stages requiring mechanical reliability and thermal resilience.

FAQ
What is the maximum continuous drain current for AUIRF1404ZL at 100°C case temperature?
The maximum continuous drain current for AUIRF1404ZL at TC = 100°C is 120 A (silicon-limited), as specified in the Absolute Maximum Ratings table. This value reflects thermal derating due to reduced channel conductivity and increased RDS(on) at elevated temperatures, and assumes proper heatsinking with RθJC ≤ 0.75°C/W.
Is AUIRF1404ZL pin-compatible with AUIRF1404Z or AUIRF1404ZS?
No-AUIRF1404ZL uses TO-262 packaging with straight leads and an isolated drain tab, while AUIRF1404Z is TO-220AB and AUIRF1404ZS is D2PAK. Pin spacing, mounting hole pattern, and thermal interface geometry differ significantly; mechanical redesign is required for substitution.
Does AUIRF1404ZL require a gate resistor for safe switching in automotive applications?
Yes-a gate resistor (typically 2.2–10 Ω) is required to dampen gate oscillation and limit peak gate current during fast transitions. The 100–150 nC total gate charge and low gate threshold (2.0–4.0 V) make it susceptible to shoot-through without controlled turn-on/turn-off timing, especially in half-bridge configurations.
Can AUIRF1404ZL be used in synchronous rectification for 48 V mild-hybrid systems?
No-AUIRF1404ZL is rated for 40 V VDS, making it unsuitable for 48 V nominal systems where transient voltages can exceed 60 V during load dump. For 48 V applications, Infineon's AUIRF3004-7P (60 V, TO-220AB) or AUIRF3205-7P (55 V, TO-262) are qualified alternatives.
