Product details

Overview

IRL1404ZSTRL from Infineon Technologies is a logic-level N-channel Power MOSFET in D2PAK (TO-263) package, rated for 40V V_DSS, 3.1mΩ R_DS(on) at V_GS = 10V, and 120A continuous drain current at T_C = 25°C. It features 175°C junction temperature rating, fast switching (t_r = 180ns), and tested repetitive avalanche capability up to T_jmax, making it suitable for high-current DC-DC synchronous rectification and motor drive half-bridges.

For engineers reviewing the IRL1404ZSTRL datasheet, IRL1404ZSTRL pinout, IRL1404ZSTRL application, or IRL1404ZSTRL equivalent, key selection criteria include its ultra-low on-resistance at 4.5V gate drive, body diode reverse recovery charge (Q_rr = 18–27nC), thermal resistance (R_θJC = 0.65°C/W), and D2PAK lead-frame construction for high-power PCB mounting.

Technical Context

This MOSFET employs Infineon's HEXFET® advanced process technology optimized for low conduction loss and robust unclamped inductive switching. Its gate threshold voltage (V_GS(th) = 1.4–2.7V) enables direct interfacing with 3.3V/5V logic controllers without level-shifting, while the 75nC total gate charge supports efficient PWM operation at frequencies up to 200kHz in hard-switched topologies.

The integrated body diode exhibits t_rr = 26–39ns and Q_rr = 18–27nC under standardized test conditions (I_F = 75A, di/dt = 100A/μs), enabling reliable synchronous rectification in buck converters and H-bridge motor control where reverse recovery behavior directly impacts efficiency and EMI.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40V - Maximum blocking voltage before avalanche; defines use in ≤36V nominal bus systems (e.g., 24V industrial power rails).
R_DS(on) @ V_GS = 10V	3.1mΩ (typ) - Enables <1W conduction loss at 120A, critical for high-efficiency power stages.
I_D (continuous) @ T_C = 25°C	120A - Silicon-limited current; actual usable current depends on heatsinking and PCB copper area.
Q_g	75nC (typ) - Determines gate driver power requirement; compatible with standard 1A peak drivers at ≤100kHz.
R_θJC	0.65°C/W - Junction-to-case thermal resistance; requires low-impedance mechanical interface to heatsink for thermal management.
E_AS (tested)	790mJ - Single-pulse avalanche energy rating; validates ruggedness against inductive load turn-off transients.
V_GS(th)	1.4–2.7V - Logic-level threshold ensures full enhancement with 3.3V microcontroller GPIO or 5V gate drivers.

Pinout & Package

IRL1404ZSTRL uses the D2PAK (TO-263) surface-mount package with exposed drain pad for thermal and electrical connection. The package has three terminals: Gate (G), Drain (D), and Source (S), with Drain electrically connected to the metal tab.

Pin/Terminal	Circuit Role	Design Meaning
G	Gate	Controls channel conduction; requires low-impedance drive path to minimize switching losses and ringing.
D	Drain	Main high-side current path; electrically tied to exposed metal tab-must be isolated from heatsink unless referenced to same potential.
S	Source	Return path for load current; also serves as reference for gate drive; connects to power ground plane.

Key Features

Feature	Design Value
Logic-level gate drive compatibility	Operates fully enhanced at V_GS ≥ 4.5V, eliminating need for gate boosters in 3.3V/5V control systems.
Ultra-low R_DS(on)	3.1mΩ typ at 10V reduces I²R losses by >40% vs. legacy 5mΩ MOSFETs in 100A applications.
175°C maximum junction temperature	Enables operation in sealed enclosures or high-ambient environments without derating below 125°C-rated alternatives.
Repetitive avalanche rated	Validated for repeated unclamped inductive switching up to T_jmax, reducing need for external snubbers in motor drives.

Applications

DC-DC Synchronous Rectifier

Automotive Body Control Module

Use Scenario: High-current buck converter in server VRM or telecom PSU delivering 50–100A at 5–12V output.

IC Role / Device Role / Timing Role: Low-side synchronous rectifier replacing Schottky diode to reduce conduction loss and improve efficiency above 90%.

Use Value: 3.1mΩ R_DS(on) cuts rectifier loss to <0.75W at 100A, enabling smaller heatsinks and higher power density vs. 5mΩ alternatives.

Use Scenario: Load switching for headlights, HVAC fans, or seat motors in 12V vehicle electrical architecture.

IC Role / Device Role / Timing Role: High-current N-channel high-side switch controlled via gate driver IC (e.g., IR2104) with bootstrap supply.

Use Value: 175°C T_jmax and 790mJ E_AS ensure reliability during load dump transients and motor stall events per ISO 7637-2.

Industrial Motor Drive Half-Bridge

UPS Inverter Output Stage

Use Scenario: 2–5kW BLDC or stepper motor drive with 24–48V DC bus and PWM switching at 10–20kHz.

IC Role / Device Role / Timing Role: Low-side switch in totem-pole configuration; body diode handles freewheeling current during dead-time.

Use Value: Q_rr = 18–27nC minimizes commutation loss and voltage overshoot during diode recovery, reducing EMI filter burden.

Use Scenario: Pure-sine-wave UPS output stage converting 48V DC to 120/230V AC using full-bridge topology.

IC Role / Device Role / Timing Role: High-current switching element in H-bridge leg; conducts bidirectional current via body diode during modulation.

Use Value: Fast t_r/t_f (180ns/49ns) and low C_oss (970pF) enable clean zero-voltage switching transitions and reduced switching loss at 50kHz carrier frequency.

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
IRL1404PBF	Same silicon die, TO-220AB through-hole package; R_θJA = 62°C/W (vs. 40–55°C/W for D2PAK on PCB).	Limited to lower-power or prototyping use due to inferior thermal performance; no exposed drain pad for heatsinking.	Select when manual soldering or socket-based testing is required; avoid in production high-current designs.
STP120N4F6	40V, 3.2mΩ, 120A, but V_GS(th) = 2.0–4.0V; higher Q_g = 95nC; not avalanche-rated.	Requires stronger gate drive; unsuitable for avalanche-prone inductive loads without external protection.	Choose only if cost is primary constraint and system lacks unclamped inductive stress; verify gate drive strength.

Compared with IRL1404PBF and STP120N4F6, IRL1404ZSTRL delivers superior thermal performance via D2PAK's low R_θJC, guaranteed avalanche ruggedness, and tighter V_GS(th) distribution-making it the preferred choice for volume production in thermally constrained, high-reliability power stages.

FAQ

What is the maximum continuous drain current for IRL1404ZSTRL at 100°C case temperature?

At T_C = 100°C, the continuous drain current is derated to 140A per the Absolute Maximum Ratings table. This value reflects silicon-limited current under ideal thermal conditions; actual usable current depends on PCB copper area, heatsink interface, and ambient airflow.

Does IRL1404ZSTRL require a gate resistor for safe operation?

Yes-a gate resistor (typically 4.0–10Ω) is recommended to dampen gate-source ringing and control dV/dt during switching. The datasheet specifies t_d(on), t_r, t_d(off), and t_f with R_G = 4.0Ω, confirming this value optimizes speed versus oscillation risk in typical layouts.

Can IRL1404ZSTRL be used in parallel configurations?

Yes-its positive R_DS(on) temperature coefficient (R_DS(on) increases with temperature) enables inherent current sharing. However, layout symmetry (matched gate and source inductance) and individual gate resistors are essential to prevent dynamic imbalance during switching transitions.

Is the body diode of IRL1404ZSTRL suitable for synchronous rectification?

Yes-the body diode is characterized with t_rr = 26–39ns and Q_rr = 18–27nC at I_F = 75A, making it viable for synchronous rectification in buck converters up to ~200kHz. However, external Schottky diodes may still be preferred in ultra-high-frequency or low-Q_rr designs.
