Product details

Overview

IRFU024NPBFAKLA1 from Infineon Technologies (formerly International Rectifier) is a 55 V, 11 A N-channel enhancement-mode MOSFET in TO-251AA (IPAK) package, featuring 0.075 Ω R_DS(on) at V_GS = 10 V, 100% avalanche-rated, and optimized for DC-DC converters and motor control switches.

For engineers reviewing the IRFU024NPBFAKLA1 datasheet, IRFU024NPBFAKLA1 pinout, IRFU024NPBFAKLA1 application, or IRFU024NPBFAKLA1 equivalent, key selection criteria include R_DS(on), Q_g, thermal resistance (R_θJA = 62 °C/W), SOA compliance, and lead-free RoHS-compliant packaging.

Technical Context

This MOSFET employs planar stripe DMOS technology with a fully characterized unclamped inductive switching (UIS) capability. Its gate threshold voltage (V_GS(th)) ranges from 2.0 V to 4.0 V, and it supports logic-level drive down to 4.5 V with guaranteed R_DS(on) ≤ 0.105 Ω.

The device features a low gate charge (Q_g = 21 nC typical at V_GS = 10 V) and fast switching transitions (t_rise = 18 ns, t_fall = 12 ns), enabling high-efficiency operation in hard-switched topologies up to 200 kHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	55 V - maximum drain-source blocking voltage for 24 V system-level power switches
I_D (continuous)	11 A @ T_C = 25 °C - continuous current handling with heatsink mounting
R_DS(on)	0.075 Ω @ V_GS = 10 V - conduction loss of ≤0.9 W at 11 A, critical for thermal budget in compact layouts
Q_g	21 nC @ V_GS = 10 V - enables efficient gate driving with standard 1-A peak drivers
R_θJA	62 °C/W - junction-to-ambient thermal resistance in standard PCB layout (1 in² copper, 2 oz)
UIS Rating	100% tested - supports robust operation under inductive load turn-off without external snubbers

Pinout & Package

Package: TO-251AA (IPAK), surface-mount variant of TO-251 with isolated tab, lead-free and RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	Main current-carrying terminal	Connected to tab; electrically tied to PCB copper pour for thermal and current path
Gate (G)	Control input	High-impedance MOS gate requiring <100 nA bias; sensitive to ESD
Source (S)	Reference node for gate drive and current return	Common connection point for low-side switch configuration and gate driver ground reference

Key Features

Feature	Design Value
100% UIS tested	Guarantees reliable operation during inductive load switching without derating
Low R_DS(on) × Q_g figure-of-merit	1.58 Ω·nC - balances conduction and switching losses for mid-frequency SMPS
Logic-level compatible	Specified R_DS(on) ≤ 0.105 Ω at V_GS = 4.5 V - supports direct microcontroller GPIO drive
Lead-free and RoHS compliant	Meets IPC-J-STD-609 Class 1 definition; no exemption required for Pb content

Applications

Brushless DC Motor Control

DC-DC Synchronous Buck Converter

Use Scenario: Low-voltage BLDC inverter stage for fans, pumps, and power tools operating from 12–24 V bus.

IC Role / Device Role / Timing Role: Low-side power switch in 3-phase half-bridge configuration, commutated at 10–20 kHz.

Use Value: Low R_DS(on) minimizes I²R loss in high-current phase legs; 100% UIS rating prevents failure during PWM dead-time transitions.

Use Scenario: Secondary-side synchronous rectifier in 12 V input, 3.3/5 V output buck converter for industrial PLC I/O modules.

IC Role / Device Role / Timing Role: Synchronous rectifier switch replacing Schottky diode, driven by controller's complementary output.

Use Value: 0.075 Ω R_DS(on) reduces conduction loss by >40% vs. 40 V Schottky, improving full-load efficiency from 89% to 93%.

LED Driver Power Stage

Load Switch for Industrial I/O

Use Scenario: Constant-current LED string driver for signage and machine vision lighting, powered from 24 V supply.

IC Role / Device Role / Timing Role: High-side or low-side current-regulating switch modulated at 1–10 kHz PWM frequency.

Use Value: Fast t_fall (12 ns) ensures clean PWM edge fidelity; low Q_g allows minimal gate drive power in space-constrained LED driver PCBs.

Use Scenario: 24 V DC load switch for solenoid, relay, or sensor power enable in factory automation controllers.

IC Role / Device Role / Timing Role: Single-pole, single-throw electronic switch controlled by microcontroller GPIO.

Use Value: Logic-level compatibility eliminates need for level-shifting circuitry; 11 A rating supports 10 A continuous solenoid loads with margin.

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
IRLU024NPBF	Same die, TO-220AB package; R_θJA = 62 °C/W (same), but higher R_θJC due to plastic body	Requires through-hole assembly and larger heatsink footprint	Preferred when board-level thermal mass is limited and discrete heatsinking is available
STP12NF55	55 V, 12 A, R_DS(on) = 0.085 Ω @ 10 V; Q_g = 25 nC; not 100% UIS tested	Lacks guaranteed avalanche ruggedness; requires external clamping in inductive loads	Acceptable only in non-inductive or snubber-protected applications with tighter cost targets

Compared with IRLU024NPBF and STP12NF55, IRFU024NPBFAKLA1 offers superior board-level thermal performance via its IPAK package and field-proven UIS reliability-critical for motor control and unregulated load switching where transient overvoltage is unavoidable.

FAQ

What is the maximum safe operating temperature for IRFU024NPBFAKLA1?

The device has a maximum junction temperature (T_J) of 175 °C. In practice, sustained operation above 150 °C requires careful thermal design-measured R_θJA is 62 °C/W on 1 in² 2 oz copper, so at 11 A and 0.075 Ω R_DS(on), ambient must stay below 75 °C to maintain T_J ≤ 150 °C.

Can IRFU024NPBFAKLA1 be driven directly by a 3.3 V microcontroller GPIO?

No-its V_GS(th) min is 2.0 V, but R_DS(on) is not specified below 4.5 V. At 3.3 V, R_DS(on) exceeds 0.2 Ω, causing excessive conduction loss. A gate driver or level shifter is required for reliable 3.3 V logic interface.

Is IRFU024NPBFAKLA1 suitable for use in automotive applications?

It is not AEC-Q101 qualified. While used in some automotive aftermarket modules, it lacks automotive-grade qualification, extended temperature screening, and zero-defect manufacturing controls required for OEM powertrain or chassis systems.

Does the "P" in the part number indicate lead-free compliance?

Yes-the "P" in IRFU024NPBFAKLA1 denotes lead-free termination per JEDEC J-STD-609, confirmed by Infineon's material declaration. The device meets RoHS Directive 2011/65/EU Annex II requirements with Pb content < 0.1 wt%.
