Product details

Overview

IRL1404ZS from Infineon Technologies is a logic-level N-channel HEXFET® Power MOSFET designed for high-current, low-voltage switching in power supplies, motor drives, and DC-DC converters. It features 40 V V_DSS, 3.1 mΩ R_DS(on) at V_GS = 10 V, 120 A continuous drain current (T_C = 25°C), 175°C maximum junction temperature, and rated repetitive avalanche energy up to 490 mJ.

For engineers reviewing the IRL1404ZS datasheet, IRL1404ZS pinout, IRL1404ZS application, or IRL1404ZS equivalent, key selection criteria include on-resistance at 4.5 V gate drive, thermal performance under pulsed load, body diode recovery characteristics, and package-specific current derating in TO-262 (I²P) mounting configurations.

Technical Context

This MOSFET employs advanced silicon processing to minimize conduction losses while maintaining robust switching behavior. Its ultra-low R_DS(on) enables high-efficiency operation in synchronous rectification and high-side/low-side switch topologies with gate drive voltages as low as 4.5 V.

The device integrates a fast-recovery body diode (t_rr = 26–39 ns, Q_rr = 18–27 nC) and supports unclamped inductive switching with validated repetitive avalanche capability up to T_jmax, enabled by optimized die metallization and bond wire design.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40 V - Maximum blocking voltage before avalanche onset; suitable for 24 V and 36 V bus systems.
R_DS(on) @ V_GS = 10 V	3.1 mΩ typ - Enables ≤ 4.7 W conduction loss at 120 A; critical for thermal management in compact PCB layouts.
I_D Continuous @ T_C = 25°C	120 A - Silicon-limited current; requires heatsinking to sustain full rating.
T_J max	175°C - Allows operation in high-ambient industrial environments without derating below 125°C ambient.
E_AS Tested	490 mJ - Validated single-pulse avalanche energy; supports reliable inductive turn-off in motor control.
Q_g	75 nC typ - Determines gate driver power requirement; compatible with standard 1–2 A peak drivers.
t_rr	26 ns min - Reduces switching loss and EMI during body diode commutation in buck and half-bridge stages.

Pinout & Package

IRL1404ZS is supplied in the TO-262 (I²P) package - a surface-mount variant of TO-220 with isolated tab and gull-wing leads. Thermal resistance R_θJC = 0.65°C/W enables direct heatsink attachment via the exposed drain pad.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path output / heat sink interface	Electrically connected to package tab; must be isolated from PCB ground unless used as common drain node.
Source	Reference node for gate drive and current sensing	Low-inductance source connection critical for stable gate control; internal LS = 7.5 nH limits high-di/dt noise coupling.
Gate	Control terminal for channel conduction	Logic-compatible threshold (V_GS(th) = 1.4–2.7 V); requires <200 nA leakage handling in high-impedance bias networks.

Key Features

Feature	Design Value
Logic-level gate drive compatibility	Guaranteed R_DS(on) ≤ 5.9 mΩ at V_GS = 4.5 V - eliminates need for gate boosters in 5 V microcontroller-driven systems.
Repetitive avalanche rating	Validated up to T_jmax with E_AR = 220 mJ at 1% duty cycle - enables ruggedized operation in solenoid and relay driving without snubbers.
Enhanced thermal performance	R_θJC = 0.65°C/W - allows >100 W dissipation with modest heatsink; superior to TO-220AB (R_θJC = 0.75°C/W) in same footprint.
Fast body diode recovery	Q_rr = 18–27 nC with t_rr = 26–39 ns - reduces cross-conduction loss and voltage overshoot in synchronous rectifiers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current logic-level MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL120N4L10AG	R_DS(on) = 3.0 mΩ @ 10 V but higher Q_g = 105 nC; TO-263 package with R_θJC = 0.7°C/W	Requires stronger gate driver; less effective heatsinking than IRL1404ZS in same board area	Prefer when lower R_DS(on) outweighs gate drive overhead and thermal margin is available.
IXTP120N04T4	R_DS(on) = 3.2 mΩ @ 10 V; TO-220 package with R_θJC = 0.75°C/W; no specified repetitive avalanche rating	Lacks validated avalanche endurance; unsuitable for unclamped inductive loads	Select only for resistive or lightly inductive switching where avalanche stress is absent.

Compared with STL120N4L10AG and IXTP120N04T4, IRL1404ZS offers superior thermal resistance and guaranteed repetitive avalanche performance-critical for motor drive and industrial power supply designs where reliability under transient overload is mandatory.

FAQ

What is the maximum continuous drain current for IRL1404ZS at 100°C case temperature?

The maximum continuous drain current for IRL1404ZS at T_C = 100°C is 140 A, as specified in the Absolute Maximum Ratings table under "ID @ TC = 100°C Continuous Drain Current, VGS @ 10V". This rating assumes proper heatsinking and is limited by silicon thermal capacity-not package constraints.

Does IRL1404ZS support gate drive from a 3.3 V microcontroller?

No-IRL1404ZS is not fully enhanced at 3.3 V. Its gate threshold voltage ranges from 1.4 V to 2.7 V, but R_DS(on) is only guaranteed ≤5.9 mΩ at V_GS = 4.5 V. At 3.3 V, R_DS(on) rises significantly (not characterized), risking excessive conduction loss and thermal runaway under load.

How does the TO-262 package of IRL1404ZS differ electrically from TO-220AB?

The TO-262 (I²P) package uses gull-wing leads instead of through-hole pins, offering lower assembly cost and improved mechanical stability. Electrically, it shares identical die and R_DS(on)/Q_g specs, but achieves R_θJC = 0.65°C/W versus 0.75°C/W for TO-220AB due to optimized thermal path geometry and solder joint design.

Is the body diode in IRL1404ZS suitable for reverse recovery in hard-switched PFC stages?

No-the body diode is optimized for synchronous rectification, not PFC. Its t_rr = 26–39 ns and Q_rr = 18–27 nC are insufficient for continuous 50–100 kHz hard-switched boost PFC; dedicated ultrafast diodes or SiC Schottkys are required to avoid excessive loss and voltage spikes.
