Product details

Overview

IRLR014NTRPBF from Infineon Technologies (formerly International Rectifier) is a 55 V, 10 A logic-level N-channel Power MOSFET in D-Pak (TO-252) package, featuring R_DS(on) = 0.14 Ω @ V_GS = 10 V and 0.21 Ω @ V_GS = 4.5 V, fully avalanche-rated, and optimized for DC-DC converters, motor control, and load switching in industrial power supplies.

For engineers reviewing the IRLR014NTRPBF datasheet, IRLR014NTRPBF pinout, IRLR014NTRPBF application, or IRLR014NTRPBF equivalent, key selection criteria include logic-level gate drive compatibility (V_GS(th) = 1.0–2.0 V), low R_DS(on) at 4.5 V, fast switching (t_r = 47 ns, t_f = 23 ns), and rugged unclamped inductive switching capability (E_AS = 35 mJ).

Technical Context

This HEXFET device uses fifth-generation silicon process technology to achieve high current density and low conduction loss while maintaining robust safe operating area (SOA) up to 100 V and 10 A in pulse mode. Its internal source/drain inductances (L_S = 7.5 nH, L_D = 4.5 nH) and low Crss (38 pF) support clean, high-speed switching with minimal Miller-induced turn-on risk.

The MOSFET integrates a co-packaged body diode with V_SD = 1.3 V @ I_S = 6 A and fast reverse recovery (t_rr = 37–56 ns, Q_rr = 48–71 nC), enabling efficient synchronous rectification and flyback operation without external diode supplementation in many mid-power topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	55 V - Maximum blocking voltage; supports 48 V nominal bus systems with 15% margin.
R_DS(on) @ 10 V	0.14 Ω - Enables ≤1.4 W conduction loss at 10 A DC, suitable for continuous-duty thermal design.
R_DS(on) @ 4.5 V	0.21 Ω - Confirmed logic-level drive compatibility with 3.3 V/5 V microcontrollers and gate drivers.
Q_g	7.9 nC - Low total gate charge reduces driver power demand and enables >500 kHz PWM operation.
E_AS	35 mJ - Single-pulse avalanche energy rating allows reliable unclamped inductive switching in motor drives.
t_r/t_f	47 ns / 23 ns - Fast edge rates minimize switching losses in hard-switched SMPS and half-bridge configurations.
Thermal R_θJC	5.3 °C/W - Junction-to-case resistance enables direct heatsink mounting for 28 W P_D dissipation.

Applications

DC-DC Buck Converter

Brushed DC Motor Driver

Use Scenario: 12 V–48 V input, 3.3 V/5 V/12 V output buck regulator in industrial PLCs and embedded power modules.

IC Role / Device Role / Timing Role: High-side or low-side synchronous switch; handles peak currents up to 10 A with <1.4 W conduction loss.

Use Value: R_DS(on) = 0.14 Ω @ 10 V and fast t_f = 23 ns reduce total power loss and improve efficiency above 92% at 5 A load.

Use Scenario: H-bridge or half-bridge control of 24 V brushed motors in robotics, HVAC actuators, and medical pumps.

IC Role / Device Role / Timing Role: Low-side switch in half-bridge; withstands back-EMF spikes via 35 mJ avalanche rating.

Use Value: Fully rated for unclamped inductive switching - eliminates external TVS/clamp diodes and simplifies board layout.

Hot-Swap Controller

Load Switch for FPGA/ASIC Core Rails

Use Scenario: Inrush-limited 5 V/12 V hot-swap circuit protecting backplane slots and modular power supplies.

IC Role / Device Role / Timing Role: Main pass element; controlled turn-on via gate resistor to limit dI/dt during insertion.

Use Value: Low R_DS(on) = 0.21 Ω @ 4.5 V ensures <0.5 V drop at 2 A, preserving rail accuracy and minimizing heat rise.

Use Scenario: Sequenced core voltage enable (e.g., 1.2 V, 1.8 V) for FPGAs and SoCs requiring precise power-up timing and low quiescent loss.

IC Role / Device Role / Timing Role: High-side load switch; driven directly by 3.3 V GPIO with no external level shifter.

Use Value: V_GS(th) ≤ 2.0 V and Q_g = 7.9 nC allow clean, sub-microsecond turn-on with minimal overshoot or shoot-through risk.

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	R_DS(on) = 0.075 Ω @ 10 V, higher ID = 18 A, larger die size	Better for >12 A continuous loads; higher capacitance (C_iss = 520 pF) limits max frequency	Select when lower conduction loss outweighs switching speed requirements.
STP55NF06L	R_DS(on) = 0.022 Ω @ 10 V, but V_GS(th) = 1–2.5 V; TO-220 package	Higher current capability (55 A), but through-hole mounting and larger footprint	Prefer for prototyping or high-current legacy designs where D-Pak is not feasible.

Compared with IRLR2905TRPBF and STP55NF06L, the IRLR014NTRPBF offers optimal balance of logic-level drive, D-Pak footprint, and 10 A capability - making it ideal for space-constrained, medium-power industrial SMPS and motor control where thermal performance and gate drive simplicity are prioritized over ultra-low R_DS(on).

FAQ

What is the maximum continuous drain current at 100°C case temperature?

The IRLR014NTRPBF supports 7.1 A continuous drain current at T_C = 100°C with V_GS = 10 V, per the Absolute Maximum Ratings table. This derating reflects thermal limits of the D-Pak package and must be validated against actual PCB copper area and airflow in the target application.

Does this MOSFET require a gate resistor for stability in switching applications?

Yes - a series gate resistor (typically 5–22 Ω) is recommended to dampen ringing caused by gate loop inductance and prevent spurious turn-on due to dv/dt coupling. The device's low Q_gd/Q_gs ratio (4.4 nC / 1.4 nC) improves Miller immunity, but external R_G remains essential for reliable hard-switching operation.

Can the body diode be used for freewheeling in a synchronous buck converter?

Yes - the integrated body diode has V_SD = 1.3 V @ 6 A and t_rr = 37–56 ns, making it usable for low-frequency (<100 kHz) freewheeling. However, for synchronous rectification above 200 kHz, an external Schottky diode or second MOSFET is preferred to minimize conduction and recovery losses.

Is the "PbF" suffix sufficient to confirm RoHS compliance?

Yes - the "PbF" suffix in IRLR014NTRPBF explicitly denotes lead-free termination and full compliance with EU RoHS Directive 2011/65/EU. Infineon's material declarations confirm homogeneous lead content <1000 ppm across all package elements, including solder plating and mold compound.
