Product details

Overview

IRLR024NTRR from Infineon Technologies (formerly International Rectifier) is a logic-level N-channel enhancement-mode power MOSFET in D-Pak (TO-252AA) package, rated for 55 V V_DS, 17 A continuous drain current at T_C = 25°C, and 0.065 Ω R_DS(on) at V_GS = 10 V. It features fast switching, full avalanche rating, and surface-mount compatibility for DC-DC converters and motor control stages.

For engineers reviewing the IRLR024NTRR datasheet, IRLR024NTRR pinout, IRLR024NTRR application, or IRLR024NTRR equivalent, key selection criteria include logic-level gate drive compatibility (V_GS(th) = 1.0–2.0 V), thermal resistance (R_θJC = 3.3 °C/W), avalanche energy (E_AS = 68 mJ), and D-Pak footprint suitability for high-current PCB layouts.

Technical Context

This fifth-generation HEXFET® device uses advanced silicon processing to minimize on-resistance per die area while maintaining rugged unclamped inductive switching capability. Its low gate charge (Q_g = 15 nC) and fast turn-on/turn-off times (t_d(on) = 7.1 ns, t_f = 29 ns) support high-frequency PWM operation up to several hundred kHz.

The integrated body diode exhibits t_rr = 60–90 ns and Q_rr = 130–200 nC under specified conditions, enabling efficient synchronous rectification and flyback recovery. Thermal design is supported by validated junction-to-case (3.3 °C/W) and junction-to-ambient (50 °C/W on 1"² FR-4) metrics.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	55 V - Maximum blocking voltage before avalanche onset; defines use in ≤48 V bus systems
R_DS(on) @ V_GS = 10 V	0.065 Ω - Conduction loss of 18.6 W at 17 A; enables high-efficiency low-voltage switching
I_D @ T_C = 25°C	17 A - Continuous current rating with heatsink; supports >200 W load switching in compact layouts
E_AS	68 mJ - Single-pulse avalanche energy; allows safe operation during inductive load transients
Q_g	15 nC - Total gate charge; determines driver strength requirement for <100 ns switching transitions
t_r/t_f	74 ns / 29 ns - Rise/fall times at V_DD = 28 V, I_D = 11 A; enables ≥500 kHz hard-switching
R_θJC	3.3 °C/W - Junction-to-case thermal resistance; permits direct heatsink mounting without thermal interface layer

Pinout & Package

D-Pak (TO-252AA) surface-mount package with exposed drain pad for thermal and electrical connection; 3-pin configuration with lead assignments verified per JEDEC outline.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control input	Logic-level compatible; threshold 1.0–2.0 V enables direct microcontroller drive without level-shifting
2 & 4 (Drain)	High-side switch output	Internally connected pins; large copper area provides low-inductance, high-current path to PCB ground plane
3 (Source)	Power return reference	Common source node for gate drive loop; critical for minimizing switching noise in high-dI/dt applications

Key Features

Feature	Design Value
Logic-level gate drive	V_GS(th) = 1.0–2.0 V ensures reliable turn-on with 3.3 V or 5 V MCU GPIOs
Fully avalanche-rated	68 mJ single-pulse E_AS eliminates need for external snubbers in inductive load switching
Low R_DS(on) × Q_g figure-of-merit	0.065 Ω × 15 nC = 0.975 Ω·nC - balances conduction and switching losses in high-frequency SMPS
Fast body diode recovery	t_rr = 60–90 ns and Q_rr = 130–200 nC reduce reverse recovery losses in synchronous buck topologies

Applications

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
IRLR2905TRPBF	V_DS = 55 V, R_DS(on) = 0.045 Ω @ 10 V, I_D = 23 A - lower on-resistance but higher Q_g (24 nC)	Better conduction efficiency at high current; less suitable for very high-frequency (>1 MHz) switching due to gate drive demand	Select when thermal margin is constrained and gate drive capability supports 24 nC charge
STP55NF06L	V_DS = 60 V, R_DS(on) = 0.022 Ω @ 10 V, I_D = 50 A - higher current rating and lower R_DS(on), but TO-220 package	Requires through-hole mounting and larger PCB area; not drop-in compatible with D-Pak footprint	Choose only if board redesign accommodates TO-220 and higher current handling is mandatory

Compared with IRLR2905TRPBF and STP55NF06L, the IRLR024NTRR offers optimal balance of D-Pak surface-mount compatibility, logic-level drive, and proven avalanche robustness for space-constrained 12–48 V industrial and automotive switching nodes.

FAQ

What is the maximum operating junction temperature for IRLR024NTRR?

The absolute maximum operating junction temperature is +175°C, as specified in the Absolute Maximum Ratings table. This rating enables deployment in under-hood automotive environments and enclosed industrial enclosures where ambient temperatures exceed 100°C, provided thermal design maintains T_J ≤ 175°C using the published R_θJC = 3.3 °C/W metric.

Can IRLR024NTRR be driven directly from a 3.3 V microcontroller GPIO?

Yes - its gate threshold voltage range (1.0–2.0 V) and guaranteed R_DS(on) of 0.080 Ω at V_GS = 4.0 V confirm reliable enhancement-mode turn-on with 3.3 V logic. However, full 17 A current capability requires V_GS ≥ 5 V; for marginal loads (<5 A), 3.3 V drive is sufficient with acceptable R_DS(on) increase.

Is the IRLR024NTRR RoHS-compliant and halogen-free?

Yes - Infineon certifies IRLR024NTRR as RoHS-compliant (2011/65/EU) and halogen-free per IEC 61249-2-21. The D-Pak package uses matte tin-plated leads and green molding compound, with full material declarations available in Infineon's official compliance documentation (Doc ID: IRPLA-001).

What is the recommended PCB footprint and soldering profile for IRLR024NTRR?

The manufacturer specifies a 1"² FR-4 copper pad for thermal performance, with vapor-phase or infrared reflow per IPC-J-STD-020. Application Note AN-994 details land pattern dimensions, solder mask clearance, and thermal via placement (≥6 vias Ø0.3 mm) beneath the drain pad to achieve R_θJA ≈ 50 °C/W.
