Product details
Overview
IRL1404STRLPBF from Infineon Technologies (formerly International Rectifier) is a 40 V, 160 A, logic-level N-channel D2Pak surface-mount power MOSFET with RDS(on) = 4.0 mΩ at VGS = 10 V and 5.9 mΩ at VGS = 4.3 V. It features fully avalanche-rated ruggedness, fast switching (tr = 270 ns, tf = 130 ns), and is optimized for high-current DC-DC converters and motor drive half-bridges.
For engineers reviewing the IRL1404STRLPBF datasheet, IRL1404STRLPBF pinout, IRL1404STRLPBF application, or IRL1404STRLPBF equivalent, key selection criteria include its low RDS(on) at 4.3 V gate drive, 640 A pulsed drain capability, 520 mJ single-pulse avalanche energy, and D2Pak thermal performance (RθJC = 0.75 °C/W).
Technical Context
This seventh-generation HEXFET® device uses advanced silicon processing to minimize conduction loss while maintaining robust unclamped inductive switching capability. Its gate charge profile (Qg = 140 nC, Qgd = 60 nC) supports efficient high-frequency operation up to several hundred kHz in synchronous buck stages.
The integrated body diode exhibits trr = 63–94 ns and Qrr = 170–250 nC under 100 A/µs di/dt, enabling reliable freewheeling in hard-switched topologies. Thermal design is anchored by a low junction-to-case resistance (0.75 °C/W) and 200 W continuous power dissipation at TC = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40 V - Maximum blocking voltage for 12 V/24 V automotive and industrial bus applications |
| RDS(on) @ VGS = 10 V | 4.0 mΩ - Enables ≤0.64 W conduction loss at 160 A DC, critical for high-efficiency power stages |
| RDS(on) @ VGS = 4.3 V | 5.9 mΩ - Supports direct microcontroller GPIO drive without level-shifting in logic-level systems |
| ID @ TC = 25 °C | 160 A - Sustained current rating requiring heatsink mounting and PCB copper area ≥ 10 cm² |
| EAS | 520 mJ - Withstands single-event inductive energy spikes in motor control and solenoid drivers |
| Qg | 140 nC - Determines gate driver power requirement (~1.4 mW per 100 kHz switching cycle at 10 V) |
| tr/tf | 270 ns / 130 ns - Limits switching losses in 100–500 kHz SMPS designs with controlled dv/dt |
Pinout & Package
The IRL1404STRLPBF is housed in a D2Pak (TO-263) surface-mount package with exposed drain pad for thermal and electrical connection. The package supports up to 2.0 W dissipation in standard PCB mount and enables high-current routing via the drain tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab / Pin 2 (Drain) | Main power output terminal | Electrically and thermally connected to die drain; must be soldered to large copper pour or heatsink |
| Pin 1 (Gate) | Control input | High-impedance MOS gate requiring <1 µA bias; sensitive to ESD and ringing |
| Pin 3 (Source) | Power return reference | Common node for load return and gate drive reference; carries full load current |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate threshold | VGS(th) = 1.0–3.0 V enables direct 3.3 V/5 V MCU drive without external level shifters |
| Fully avalanche rated | Rated for 520 mJ single-pulse and 20 mJ repetitive avalanche ensures reliability in inductive load switching |
| Ultra-low RDS(on) | 4.0 mΩ at 10 V reduces conduction loss by >35% vs. prior-gen 40 V MOSFETs in same package |
| Dynamic dv/dt immunity | Rated for 5.0 V/ns - suppresses false turn-on during high-speed switching in noisy environments |
| Lead-free construction | Meets RoHS Directive 2011/65/EU; compatible with Pb-free reflow profiles (peak 300 °C, 10 s) |
Applications
| Motor Drive Half-Bridge | DC-DC Synchronous Buck Converter |
|---|---|
Use Scenario: High-current BLDC motor phase leg in e-bike controllers and industrial actuators. IC Role / Device Role / Timing Role: Low-side switch in half-bridge topology handling 100–160 A continuous current with PWM switching at 20–50 kHz. Use Value: 4.0 mΩ RDS(on) minimizes I²R heating during stall conditions; 640 A pulsed rating accommodates startup surge. | Use Scenario: Primary high-current switch in 12 V input → 1.2 V/120 A output VRM for server CPUs. IC Role / Device Role / Timing Role: Synchronous rectifier in buck converter operating at 300–500 kHz with 4.3 V gate drive from controller. Use Value: 5.9 mΩ RDS(on) at 4.3 V eliminates need for gate driver IC, reducing BOM count and layout complexity. |
| Automotive Body Control Module | Industrial Solenoid Driver |
Use Scenario: Power distribution switch for headlights, HVAC fans, and seat motors in 12 V vehicle architectures. IC Role / Device Role / Timing Role: High-side or low-side load switch with integrated diagnostics and overcurrent protection. Use Value: 175 °C max junction temperature and -55 °C min storage enable under-hood deployment; 520 mJ EAS absorbs inductive kickback from relay coils. | Use Scenario: Direct-drive interface between PLC output and 24 V/10 A industrial solenoids or valves. IC Role / Device Role / Timing Role: Fast-turning power switch controlling solenoid actuation timing with <100 µs response. Use Value: 130 ns fall time ensures precise pulse-width control; body diode trr < 94 ns prevents cross-conduction in H-bridge configurations. |
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 |
|---|---|---|---|
| IRF1404ZPbF | RDS(on) = 4.7 mΩ @ 10 V; higher gate charge (Qg = 160 nC); TO-220 package | Through-hole mounting only; less suitable for automated SMT assembly | Select when board space allows through-hole and thermal path permits TO-220 heatsinking |
| STP160NF04 | RDS(on) = 4.0 mΩ @ 10 V; lower ID rating (160 A @ TC = 25 °C but derated faster); TO-220FP package | Shorter creepage distance; not rated for 175 °C operation | Prefer for cost-sensitive consumer applications where 150 °C max junction suffices |
Compared with IRF1404ZPbF and STP160NF04, the IRL1404STRLPBF uniquely combines D2Pak surface-mount compatibility, 4.3 V logic-level drive, 175 °C operation, and industry-leading 4.0 mΩ RDS(on), making it optimal for high-reliability, high-density, and high-temperature industrial power stages.

FAQ
What is the maximum continuous drain current at 100 °C case temperature?
The IRL1404STRLPBF supports 110 A continuous drain current at TC = 100 °C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limits of the D2Pak package and requires adequate heatsinking or forced-air cooling to sustain.
Does this MOSFET require a gate resistor for stability?
Yes - a gate resistor (typically 2.5–10 Ω) is recommended to dampen gate-source ringing and control switching speed. The datasheet specifies td(on), tr, td(off), and tf using RG = 2.5 Ω, confirming its necessity for predictable timing and EMI control.
Can the body diode be used for synchronous rectification?
No - the body diode is optimized for freewheeling, not reverse conduction. Its reverse recovery charge (Qrr = 170–250 nC) and time (trr = 63–94 ns) cause significant switching loss if actively commutated. External Schottky or synchronous FETs are preferred for true synchronous rectification.
Is the D2Pak drain tab electrically isolated from the PCB ground plane?
No - the D2Pak drain tab is internally connected to the MOSFET's drain terminal and must be soldered to a copper pour designated as the high-side power net. Electrical isolation requires insulating thermal pads or ceramic substrates, not standard FR-4 mounting.
