Product details
Overview
IRFU024NPBF from Infineon Technologies (formerly International Rectifier) is a 55 V, 11 A N-channel enhancement-mode MOSFET in TO-251AA (IPAK) package, featuring RDS(on) = 0.075 Ω at VGS = 10 V, 25 °C, and 45 nC total gate charge. It serves as a low-side switching device in DC-DC converters and motor control circuits.
For engineers reviewing the IRFU024NPBF datasheet, IRFU024NPBF pinout, IRFU024NPBF application, or IRFU024NPBF equivalent, key selection criteria include its 55 V VDSS, 11 A ID continuous rating, TO-251AA thermal performance, and suitability for 200 kHz PWM-driven power stages in industrial power supplies.
Technical Context
This MOSFET employs planar stripe silicon technology with optimized cell pitch for low conduction loss and fast switching. Its gate threshold voltage (VGS(th)) ranges from 2.0 V to 4.0 V, enabling reliable turn-on with standard 5 V logic-level drivers.
The device supports repetitive avalanche energy rating of 85 mJ and features 100% UIS-tested ruggedness. Its SOA curve permits operation up to 100 µs at 55 V and 11 A under linear mode conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 55 V - Maximum drain-source blocking voltage for 24 V input systems with 2× transient margin |
| ID (continuous) | 11 A @ TC = 100 °C - Sustains full load current with heatsink in compact 25 mm² PCB area |
| RDS(on) | 0.075 Ω @ VGS = 10 V - Delivers ≤ 9.1 W conduction loss at 11 A, enabling < 65 °C junction rise |
| Qg | 45 nC - Enables efficient 200 kHz switching with ≤ 1 W gate drive loss using 5 V MCU output |
| EAS | 85 mJ - Withstands single-pulse inductive kickback without failure in relay or solenoid drive |
| PD | 42 W @ TC = 25 °C - Supports high-duty-cycle operation when mounted on 2-oz copper with thermal pad |
Pinout & Package
IRFU024NPBF uses the TO-251AA (IPAK) surface-mount package with isolated tab, rated for 1.5 W dissipation at 70 °C ambient on 1-in² 2-oz copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path from source to load | Electrically connected to exposed metal tab - must be soldered to thermal pad for safe operation |
| Gate | Control electrode for channel formation | Requires ≤ 10 V drive; 1 kΩ series resistor recommended to damp ringing during fast switching |
| Source | Reference node for gate drive and current return | Must be tied directly to power ground plane to minimize common-source inductance in high di/dt paths |
Key Features
| Feature | Design Value |
|---|---|
| Lead-free (Pb-free) construction | Complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020 reflow profile |
| 100% avalanche-rated | Guarantees survival under unclamped inductive switching stress up to 85 mJ |
| Fast body diode recovery | trr = 50 ns - Reduces reverse recovery loss in synchronous buck topologies |
| Low gate charge | Qg = 45 nC - Enables use of low-power microcontroller GPIOs without external driver stage |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP55NF06L | 60 V VDSS, 55 A ID, TO-220 package, RDS(on) = 0.018 Ω | Higher current handling but larger footprint and higher gate charge (90 nC) | Preferred for >20 A continuous loads where board space allows TO-220 mounting |
| DMN3025LSD-13 | 30 V VDSS, 12 A ID, SO-8 package, RDS(on) = 0.025 Ω | Lower voltage rating and dual-N configuration; requires external level shift for 5 V logic | Used when space-constrained designs demand dual-channel integration and 30 V bus compliance |
Compared with STP55NF06L and DMN3025LSD-13, IRFU024NPBF offers optimal balance of 55 V rating, TO-251AA thermal efficiency, and 45 nC gate drive compatibility with 5 V microcontrollers-making it ideal for mid-power industrial switching where footprint and drive simplicity are critical.

FAQ
Is IRFU024NPBF compatible with 3.3 V microcontroller gate drive?
No. Its gate threshold voltage (VGS(th)) ranges from 2.0 V to 4.0 V, but full enhancement requires ≥ 10 V for specified RDS(on). At 3.3 V, RDS(on) exceeds 0.5 Ω, causing excessive conduction loss. A gate driver IC such as TC4427 is required for logic-level compatibility.
What is the maximum PCB copper area needed for thermal management at 11 A continuous?
At 11 A and 100 °C case temperature, IRFU024NPBF requires ≥ 250 mm² (0.4 in²) of 2-oz copper connected to the drain tab via ≥ 6 thermal vias (0.3 mm diameter). Without this, junction temperature exceeds 150 °C under full load, risking premature failure.
Does IRFU024NPBF have integrated ESD protection on the gate?
No. The device lacks on-chip gate protection diodes. External 10 kΩ gate-to-source resistor and 12 V Zener clamp are mandatory to prevent electrostatic damage during handling and PCB assembly-especially in automated SMT lines with ionized air systems.
Can IRFU024NPBF replace IRFU120 in existing designs?
No. IRFU120 is a 100 V, 9.5 A MOSFET with RDS(on) = 0.18 Ω. IRFU024NPBF has lower voltage rating (55 V), higher current (11 A), and significantly lower RDS(on) (0.075 Ω). Substitution is unsafe in 48 V or higher systems and may cause overvoltage failure during transients.
