Product details

Overview

IRFR024NTRLPBF from Infineon Technologies (formerly International Rectifier) is a 55 V, 15 A N-channel enhancement-mode MOSFET in DPAK (TO-252) package, featuring 0.075 Ω R_DS(on) at V_GS = 10 V, 100% avalanche-rated, and optimized for DC-DC converter primary-side switching in industrial power supplies.

For engineers reviewing the IRFR024NTRLPBF datasheet, IRFR024NTRLPBF pinout, IRFR024NTRLPBF application, or IRFR024NTRLPBF equivalent, key selection criteria include R_DS(on), Q_g, SOA limits, thermal resistance (R_θJA = 62 °C/W), and lead-free RoHS compliance per JEDEC J-STD-020.

Technical Context

This MOSFET employs planar stripe cell technology with optimized gate oxide thickness and channel doping to achieve low conduction loss while maintaining robust unclamped inductive switching (UIS) capability. Its gate threshold voltage (V_GS(th)) of 2.0–4.0 V enables direct drive from 3.3 V and 5 V logic controllers.

The device supports hard-switched topologies up to 200 kHz and features a body diode with t_rr = 55 ns and Q_rr = 38 nC, suitable for synchronous rectification and freewheeling in buck and flyback converters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	55 V - Maximum drain-source blocking voltage for 24 V input DC-DC stages
I_D (continuous)	15 A @ T_C = 25 °C - Sustains full load current with minimal heatsinking in compact PCB layouts
R_DS(on)	0.075 Ω @ V_GS = 10 V - Delivers ≤1.7 W conduction loss at 15 A, reducing thermal stress
Q_g	29 nC - Enables efficient 100–200 kHz switching with standard gate drivers (e.g., IR2110)
R_θJA	62 °C/W - Requires ≥2 cm² 2-oz copper pour for safe operation at full current in still air
UIS Rating	100% tested - Guarantees single-pulse avalanche energy handling without derating

Pinout & Package

DPAK (TO-252) package: surface-mount, single-gauge leadframe, exposed drain pad for thermal enhancement. Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Gate (G)	Control electrode	Accepts 0–10 V logic-level signals; requires <1 µF local decoupling for stable turn-on
Drain (D)	High-side power node	Connected to exposed metal tab; must be electrically isolated from heatsink unless referenced to same potential
Source (S)	Reference node / return path	Serves as common reference for gate drive and current sensing; ties to power ground plane

Key Features

Feature	Design Value
100% UIS tested	Eliminates need for external snubbers in inductive load switching applications
Lead-free (Pb-free) and RoHS compliant	Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1) for reflow assembly
Low gate charge (Q_g = 29 nC)	Reduces driver power loss and allows use of cost-effective low-current gate drivers
Fast body diode (t_rr = 55 ns)	Minimizes reverse recovery loss in non-synchronous buck converters

Applications

Industrial DC-DC Converters

Motor Drive Half-Bridge Stages

Use Scenario: 24 V input, 5 V/10 A output buck converter in PLC power module.

IC Role / Device Role / Timing Role: Primary-side high-side switch operating at 150 kHz with PWM controller feedback.

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
STP55NF06L	R_DS(on) = 0.018 Ω @ 10 V, but V_DS = 60 V and I_D = 55 A - larger die, higher Q_g (72 nC)	Better for high-current, lower-frequency (<50 kHz) applications; less suitable for space-constrained 150 kHz designs	Choose when thermal headroom is limited and gate drive strength permits higher Q_g.
IXTP12N50L	V_DS = 500 V, R_DS(on) = 0.55 Ω - higher voltage rating but 7× higher on-resistance	Targeted at offline AC-DC PFC and flyback primary switches, not 24–48 V DC-DC	Select only if system requires >400 V blocking; avoid for low-voltage, high-efficiency DC-DC.

Compared with STP55NF06L and IXTP12N50L, IRFR024NTRLPBF offers optimal balance of R_DS(on), Q_g, and thermal footprint for 24–48 V industrial DC-DC converters where board area and switching loss are critical.

FAQ

What is the maximum junction temperature for continuous operation?

The absolute maximum junction temperature (T_J) is 175 °C. Derating begins at T_C = 25 °C, with linear reduction to zero power at 175 °C. At 15 A continuous drain current, T_J remains below 125 °C with ≥2 cm² 2-oz copper and no forced airflow, per datasheet Figure 8.

Is IRFR024NTRLPBF suitable for logic-level gate drive?

Yes - its V_GS(th) range is 2.0–4.0 V, and it delivers R_DS(on) ≤ 0.095 Ω at V_GS = 4.5 V. It is fully compatible with 3.3 V and 5 V microcontroller GPIO or dedicated logic-level gate drivers such as TC4427.

Does this part have integrated ESD protection?

No - IRFR024NTRLPBF lacks on-chip ESD protection diodes. External gate protection (e.g., 12 V Zener clamp between gate and source) is required in environments with >2 kV HBM risk, per datasheet Section 6.2 recommendations.

How does the "PBF" suffix affect soldering profile?

The "PBF" suffix indicates lead-free (Pb-free) construction and RoHS compliance. It requires peak reflow temperature of 260 °C (per JEDEC J-STD-020), with MSL1 rating allowing unlimited floor life before reflow - no baking required prior to assembly.
