Product details

Overview

IRL1404S from Infineon Technologies (formerly International Rectifier) is a 40 V, 160 A, logic-level N-channel Power MOSFET in D2Pak surface-mount package, featuring R_DS(on) = 4.0 mΩ at V_GS = 10 V and 5.9 mΩ at V_GS = 4.3 V, fully avalanche-rated with E_AS = 520 mJ, designed for high-current DC-DC converters and motor drive half-bridges.

For engineers reviewing the IRL1404S datasheet, IRL1404S pinout, IRL1404S application, or IRL1404S equivalent, key selection criteria include its low R_DS(on) at 4.3 V gate drive, fast switching (t_r = 270 ns, t_f = 130 ns), rugged unclamped inductive switching capability, and thermal performance (R_θJC = 0.75 °C/W) in high-power surface-mount designs.

Technical Context

This seventh-generation HEXFET device uses advanced silicon processing to minimize conduction loss while maintaining robust safe operating area (SOA) up to 10 ms at 100 V. Its body diode exhibits t_rr = 63–94 ns and Q_rr = 170–250 nC under 100 A/µs di/dt, enabling efficient synchronous rectification and freewheeling in hard-switched topologies.

The gate charge profile (Q_g = 140 nC, Q_gd = 60 nC) supports stable high-frequency operation with controlled Miller effect, and its dynamic dv/dt rating of 5.0 V/ns ensures noise immunity in noisy power systems without external snubbing.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40 V - Maximum blocking voltage for 12 V/24 V bus applications with margin against transients
R_DS(on) @ 10 V	4.0 mΩ - Enables ≤0.64 W conduction loss at 160 A continuous drain current
R_DS(on) @ 4.3 V	5.9 mΩ - Supports direct logic-level MCU GPIO drive without level-shifting circuitry
Q_g	140 nC - Determines gate driver power requirement and switching loss at 100–500 kHz operation
E_AS	520 mJ - Guarantees single-pulse avalanche survivability during inductive turn-off faults
t_r/t_f	270 ns / 130 ns - Enables <1 µs total switching transition for high-efficiency SMPS designs
R_θJC	0.75 °C/W - Allows 200 W power dissipation with ≤150°C junction rise over case at rated current

Pinout & Package

D2Pak (TO-262) surface-mount package with isolated tab, optimized for high-current PCB mounting and heatsink interface via soldered tab. Thermal resistance R_θCS = 0.50 °C/W with greased flat surface.

Pin/Terminal	Circuit Role	Design Meaning

Source	Reference node for gate control and current return path	Low-inductance connection critical for gate loop stability and body diode recovery performance
Gate	Control input for channel modulation	Requires low-impedance drive (<2.5 Ω series) to manage Q_gd-dominated Miller turn-off delay

Key Features

Feature	Design Value

Full avalanche rating	Eliminates need for external clamping components in inductive load switching (e.g., solenoids, relay coils)
Fast body diode recovery	Reduces switching losses and EMI in synchronous buck and H-bridge configurations with reverse recovery stress
Lead-free D2Pak package	Supports RoHS-compliant reflow assembly with 300 °C peak soldering tolerance at 1.6 mm from case

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	R_DS(on) = 4.7 mΩ @ 10 V; higher Q_g = 160 nC; same D2Pak package	Slightly higher conduction loss and slower switching; identical avalanche rating	Preferred where cost sensitivity outweighs marginal efficiency gain of IRL1404S
STP160NF04Z	R_DS(on) = 3.8 mΩ @ 10 V; Q_g = 150 nC; TO-220FP package (through-hole)	Lower R_DS(on) but no surface-mount thermal interface; lacks logic-level 4.3 V drive capability	Chosen when through-hole assembly and maximum conduction efficiency are prioritized over gate drive simplicity

Compared with IRF1404ZPbF and STP160NF04Z, the IRL1404S uniquely balances ultra-low R_DS(on), logic-level gate drive, and D2Pak thermal performance-making it optimal for space-constrained, high-current, MCU-driven power stages where gate driver integration and PCB thermal management are critical.

FAQ

What is the maximum continuous drain current for IRL1404S at 100°C case temperature?

The IRL1404S supports 110 A continuous drain current at T_C = 100°C with V_GS = 10 V, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limitations of the D2Pak package and must be validated against actual PCB copper area and heatsink interface in the target application.

Does IRL1404S require a gate driver when driven by a 3.3 V microcontroller?

No-IRL1404S is a logic-level MOSFET with V_GS(th) = 1.0–3.0 V and specified R_DS(on) = 5.9 mΩ at V_GS = 4.3 V, enabling full enhancement from standard 3.3 V or 5 V GPIO outputs. However, a low-impedance gate resistor (<10 Ω) is recommended to control ringing and ensure clean turn-on/turn-off transitions.

How does the body diode performance of IRL1404S compare to standard rectifiers in synchronous rectification?

The IRL1404S body diode has V_SD = 1.3 V at 95 A and t_rr = 63–94 ns, offering lower forward drop than Schottky diodes above ~10 A and faster recovery than standard PN diodes. Its Q_rr = 170–250 nC minimizes reverse recovery loss in high-frequency synchronous buck converters.

Can IRL1404S be used in parallel configurations for higher current handling?

Yes-the positive temperature coefficient of R_DS(on) (see Fig 4) provides inherent current sharing stability. Parallel operation requires matched gate drive paths, symmetrical PCB layout, and thermal coupling to ensure uniform junction temperature across devices; typical designs use 2–4 units for >300 A applications.
