Product details

Overview

IRL1004SPBF from Infineon Technologies (formerly International Rectifier) is a logic-level N-channel D2Pak surface-mount power MOSFET designed for high-current DC-DC conversion, motor drive half-bridges, and battery protection circuits. It delivers 130A continuous drain current at 25°C, 40V V_DSS, 6.5mΩ R_DS(on) at V_GS = 10V, and is fully avalanche-rated with 700mJ single-pulse energy capability.

For engineers reviewing the IRL1004SPBF datasheet, IRL1004SPBF pinout, IRL1004SPBF application, or IRL1004SPBF equivalent, key selection criteria include its low R_DS(on) at 4.5V gate drive, 175°C junction rating, D2Pak thermal performance (0.75°C/W R_θJC), and fast switching (t_r = 210ns, t_f = 14ns) in high-efficiency power stages.

Technical Context

This HEXFET® Fifth Generation MOSFET uses advanced silicon processing to minimize conduction loss while maintaining rugged unclamped inductive switching capability. Its logic-level gate threshold (1.0–2.0V) enables direct drive from microcontrollers and PWM controllers without level-shifting circuitry.

The device integrates a robust body diode with 78A pulsed source current rating, 1.3V forward voltage at 78A, and 78–120ns reverse recovery time - optimized for synchronous rectification and freewheeling in buck converters and H-bridge motor drivers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40V - Maximum blocking voltage in off-state; suitable for 24V and 36V industrial bus systems.
R_DS(on) @ V_GS=10V	6.5mΩ - Enables ≤0.85W conduction loss at 130A, critical for high-current PCB-mounted power stages.
I_D @ T_C=25°C	130A - Continuous current rating under heatsink-cooled conditions; defines minimum heatsink sizing.
E_AS	700mJ - Single-pulse avalanche energy; supports reliable operation during inductive load turn-off transients.
t_r/t_f	210ns/14ns - Fast switching edges reduce switching losses in 100–500kHz SMPS designs.
R_θJC	0.75°C/W - Junction-to-case thermal resistance; enables direct thermal interface to heatsink without thermal pad derating.
Q_g	100nC - Total gate charge; determines driver strength requirement (e.g., ≥2A peak for 100ns turn-on).

Pinout & Package

D2Pak (TO-262 variant) surface-mount package with exposed drain pad for thermal and electrical connection. Optimized for high-power density layouts on 1"² FR-4 PCBs, supporting up to 2.0W dissipation in standard mounting.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path output / heat sink interface	Electrically connected to exposed copper tab; must be soldered to large copper pour or heatsink for thermal management.
Source	Power return path / reference node for gate drive	Low-inductance connection point for current sensing and gate driver ground reference.
Gate	Control terminal for channel conduction	Logic-compatible input (V_GS(th) = 1.0–2.0V); requires <2.5Ω series resistance to suppress ringing during fast switching.

Key Features

Feature	Design Value
Ultra-low R_DS(on)	6.5mΩ at 10V gate drive - reduces I²R losses by >30% vs. prior-generation 40V MOSFETs in 100A applications.
Logic-level gate drive	1.0V typical V_GS(th) - eliminates need for gate driver ICs when paired with 3.3V/5V MCUs or PWM controllers.
Full avalanche rating	700mJ E_AS - guarantees safe operation under unclamped inductive switching without external snubbers.
High-temperature operation	175°C max T_J - supports sealed enclosure designs and automotive under-hood environments without derating.
Lead-free construction	RoHS-compliant, halogen-free packaging - meets IPC-J-STD-020D reflow profile requirements for Pb-free assembly.

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
IRL1404ZPBF	40V V_DSS, 4.0mΩ R_DS(on) @ 10V, but 160A I_D rating and higher Q_g (130nC)	Higher conduction efficiency at >100A, but requires stronger gate driver due to increased capacitance	Preferred where thermal margin is constrained and gate drive capability supports higher Q_g
STP130NF55	55V V_DSS, 5.5mΩ R_DS(on) @ 10V, 130A rating, but 150°C max T_J and no specified E_AS	Higher voltage headroom for 48V systems, but lacks avalanche ruggedness for inductive loads	Selected when system voltage may exceed 40V or avalanche testing is not required

Compared with IRL1004SPBF, IRL1404ZPBF offers lower R_DS(on) at the cost of higher gate charge and thermal mass, while STP130NF55 trades avalanche rating and temperature range for wider voltage margin - making IRL1004SPBF optimal for 24–36V industrial systems demanding ruggedness and logic-level drive.

FAQ

What is the maximum continuous drain current for IRL1004SPBF at 100°C case temperature?

The maximum continuous drain current is 92A at T_C = 100°C with V_GS = 10V, as specified in the Absolute Maximum Ratings table. This reflects thermal derating due to reduced heat transfer at elevated case temperatures and must be validated against actual PCB layout and heatsink performance.

Does IRL1004SPBF require a gate resistor for stability in switching applications?

Yes - a series gate resistor (typically 1–2.5Ω) is recommended to dampen gate-source ringing caused by parasitic inductance and the device's 100nC gate charge. Omitting it risks shoot-through in bridge configurations and accelerated gate oxide wear under high dv/dt conditions.

Can IRL1004SPBF be used in parallel configurations for higher current handling?

Yes - its positive R_DS(on) temperature coefficient (0.04%/°C) enables inherent current sharing. However, matched PCB trace inductance, symmetrical gate drive routing, and individual gate resistors are mandatory to prevent dynamic imbalance during switching transitions.

Is the body diode of IRL1004SPBF suitable for synchronous rectification?

No - while the body diode is rated for 78A pulsed current and 1.3V forward drop, its 78–120ns reverse recovery time and 180–270nC Q_rr make it unsuitable for high-frequency synchronous rectification. External Schottky or MOSFET-based synchronous rectifiers are required above 100kHz.
