Product details
Overview
IRLR024NPBF from Infineon Technologies (formerly International Rectifier) is a logic-level N-channel enhancement-mode power MOSFET in D-Pak surface-mount package, rated for 55 V V(BR)DSS, 17 A continuous drain current at 25°C, and 0.065 Ω RDS(on) at VGS = 10 V. It features fully avalanche-rated ruggedness, fast switching (td(on) = 7.1 ns, tf = 29 ns), and is optimized for DC-DC converters, motor control, and load switching in industrial and automotive power stages.
For engineers reviewing the IRLR024NPBF datasheet, IRLR024NPBF pinout, IRLR024NPBF application, or IRLR024NPBF equivalent, key selection criteria include its logic-level gate drive compatibility (VGS(th) = 1.0–2.0 V), low thermal resistance (RθJC = 3.3 °C/W), body diode recovery performance (trr = 60–90 ns), and lead-free RoHS-compliant packaging.
Technical Context
This HEXFET® device uses fifth-generation silicon process technology to minimize RDS(on) per die area while maintaining high avalanche energy rating (EAS = 68 mJ). Its internal structure integrates low-inductance source (LS = 7.5 nH) and drain (LD = 4.5 nH) parasitics to support clean high-speed switching.
The MOSFET operates with a transconductance (gfs) of 8.3 S at VDS = 25 V and ID = 11 A, and exhibits stable threshold voltage drift (ΔV(BR)DSS/ΔTJ = 0.061 V/°C), enabling reliable operation across –55°C to +175°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 55 V - Maximum blocking voltage before avalanche conduction; defines upper limit for DC bus or flyback clamp applications. |
| RDS(on) | 0.065 Ω @ VGS = 10 V - On-resistance directly determines conduction loss in high-current paths (e.g., 17 A yields ~18.5 W worst-case I²R loss). |
| ID (TC = 25°C) | 17 A - Continuous drain current rating under ideal heatsinking; derates linearly by 0.3 W/°C above 25°C case temperature. |
| Qg / Qgd | 15 nC / 8.5 nC - Total and Miller gate charge values govern driver strength requirements and switching transition times in hard-switched topologies. |
| trr / Qrr | 60–90 ns / 130–200 nC - Body diode reverse recovery characteristics impact shoot-through risk and EMI in synchronous rectification and H-bridge circuits. |
| EAS | 68 mJ - Single-pulse avalanche energy rating enables robust unclamped inductive switching without external snubbers in relay/motor drive designs. |
Pinout & Package
The IRLR024NPBF is housed in a D-Pak (TO-252AA) surface-mount package with three terminals: Drain (tab), Source (pin 1), and Gate (pin 2). The exposed drain pad provides low thermal resistance path to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current sink terminal | Electrically connected to exposed metal tab; must be soldered to large copper pour for thermal and electrical integrity. |
| Source (Pin 1) | Reference node for gate drive and current return | Low-inductance connection point (LS = 7.5 nH); critical for minimizing gate loop oscillation during fast switching. |
| Gate (Pin 2) | Control electrode for channel formation | Logic-compatible input requiring ≤2.0 V threshold; total gate charge (15 nC) dictates minimum driver peak current for <100 ns transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | VGS(th) = 1.0–2.0 V enables direct interface with 3.3 V or 5 V microcontrollers without level-shifting circuitry. |
| Fully avalanche rated | 68 mJ single-pulse EAS supports reliable operation in inductive load switching without external protection components. |
| Low RθJC | 3.3 °C/W junction-to-case thermal resistance allows >40 W power dissipation with moderate heatsinking on PCB. |
| Fast switching | td(on) = 7.1 ns and tf = 29 ns reduce switching losses in PWM frequencies up to 500 kHz. |
| Lead-free & RoHS compliant | Pb-free plating and halogen-free molding compound meet IPC/JEDEC J-STD-020 reflow profile requirements. |
Applications
| DC-DC Buck Converter | Automotive Door Lock Actuator |
|---|---|
Use Scenario: High-efficiency 12 V input to 5 V/3.3 V step-down conversion in infotainment head units. IC Role / Device Role: Synchronous high-side switch handling 10–15 A peak load current with <100 kHz PWM frequency. Use Value: Low RDS(on) minimizes conduction loss; fast trr prevents cross-conduction with synchronous FET during dead-time. | Use Scenario: Bidirectional 12 V motor control for power window/lock modules in passenger vehicles. IC Role / Device Role: Half-bridge low-side switch driving brushed DC motor with reverse polarity protection. Use Value: Avalanche rating absorbs inductive kickback during abrupt current interruption; logic-level gate simplifies MCU GPIO interface. |
| Industrial PLC Output Stage | LED Constant-Current Driver |
Use Scenario: Solid-state relay replacement in programmable logic controller digital output modules. IC Role / Device Role: Load switch controlling 24 V DC solenoids or indicator lamps with 2 A–10 A nominal current. Use Value: 175°C max TJ and 110 °C/W RθJA enable operation in sealed enclosures without active cooling. | Use Scenario: Dimmable constant-current driver for high-brightness LED arrays in signage and lighting fixtures. IC Role / Device Role: PWM-controlled current sink regulating LED string current up to 12 A. Use Value: Low gate charge (15 nC) reduces driver IC power consumption; tight VGS(th) tolerance ensures consistent turn-on across temperature. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRLR2905PBF | Higher V(BR)DSS (55 V same), lower RDS(on) (0.045 Ω), higher Qg (21 nC) | Better conduction efficiency at >15 A but requires stronger gate driver | Prefer when minimizing I²R loss dominates over switching loss and driver capability permits. |
| STP55NF06L | Same V(BR)DSS (60 V), higher RDS(on) (0.022 Ω), lower ID (55 A), different TO-220 package | Through-hole mounting only; higher current rating but larger footprint and worse thermal resistance | Select only if through-hole assembly is mandatory and board space is unconstrained. |
Compared with IRLR024NPBF, IRLR2905PBF delivers lower conduction loss at high current but increases gate drive demand, while STP55NF06L trades surface-mount convenience and thermal performance for higher current capacity in legacy through-hole layouts.

FAQ
Is IRLR024NPBF suitable for 3.3 V microcontroller gate drive?
Yes. With a gate threshold voltage range of 1.0–2.0 V and guaranteed turn-on at VGS = 4.0 V (RDS(on) ≤ 0.110 Ω), the IRLR024NPBF reliably switches full load current using standard 3.3 V GPIO outputs without external level shifters or gate drivers.
What is the maximum allowable PCB copper area for thermal performance?
For optimal thermal performance, the D-Pak drain tab should connect to ≥250 mm² of 2 oz copper on the top layer, thermally coupled via ≥4 thermal vias (0.3 mm diameter) to an internal ground plane. This configuration achieves RθJA ≈ 50 °C/W per datasheet test conditions.
Does IRLR024NPBF have integrated ESD protection?
No. The device lacks on-chip ESD protection diodes. External gate protection-such as a 10 kΩ series resistor and 12 V Zener clamp between gate and source-is recommended in systems exposed to handling or system-level ESD events per IEC 61000-4-2.
Can it replace IRLU024NPBF in a design?
Yes, with mechanical adaptation. Both share identical electrical specs and die, but IRLU024NPBF uses I-Pak (TO-251) through-hole packaging. Replace requires footprint redesign and requalification of thermal performance, as RθJA differs significantly between surface-mount (50 °C/W) and through-hole (62 °C/W) mounting.
