Product details

Overview

IRLR014NPBF from Infineon Technologies (formerly International Rectifier) is a 55 V, 10 A logic-level N-channel Power MOSFET in D-Pak (TO-252) surface-mount 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 IRLR014NPBF datasheet, IRLR014NPBF pinout, IRLR014NPBF application, or IRLR014NPBF 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 fifth-generation HEXFET device uses advanced planar processing to minimize on-resistance per die area while maintaining high avalanche energy tolerance. Its gate charge profile (Q_g = 7.9 nC, Q_gd = 4.4 nC) supports efficient high-frequency PWM operation up to several hundred kHz.

The integrated body diode exhibits t_rr = 37–56 ns and Q_rr = 48–71 nC under defined conditions (I_F = 6 A, di/dt = 100 A/µs), enabling synchronous rectification and flyback recovery in non-isolated topologies without external Schottky supplementation.

Key Specifications

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
IRLR2905PBF	R_DS(on) = 0.055 Ω @ 10 V, higher ID (79 A), larger D-Pak variant	Higher current density; requires larger PCB copper area and gate drive strength	Preferred when >15 A continuous current or lower conduction loss dominates design priority
STP55NF06L	R_DS(on) = 0.018 Ω @ 10 V, TO-220 package, V_GS(th) = 1–2.5 V	Through-hole mounting; higher thermal mass but no exposed drain pad for SMT thermal optimization	Selected where manual assembly, legacy board compatibility, or higher single-pulse surge rating is required

Compared with IRLR2905PBF and STP55NF06L, the IRLR014NPBF offers optimal balance of logic-level drivability, SMT thermal efficiency, and cost-effective 10 A capability-ideal for space-constrained industrial DC-DC and motor control modules where gate drive simplicity and board-level thermal management are critical.

FAQ

What is the maximum junction temperature and thermal resistance of IRLR014NPBF?

The IRLR014NPBF has a maximum operating junction temperature of +175°C and specified thermal resistances of R_θJC = 5.3°C/W (junction-to-case) and R_θJA = 50°C/W (case-to-ambient, PCB mount). These values assume standard 1 oz copper, 1 in² thermal pad layout per IRF application guidelines.

Does IRLR014NPBF require a gate resistor, and what value is recommended?

Yes-a gate resistor is required to control dV/dt and prevent ringing. For typical 3.3 V/5 V MCU drive, a 10–22 Ω series resistor is recommended. With Q_g = 7.9 nC and t_r/t_f < 50 ns, this provides stable switching while minimizing gate drive power dissipation.

Can IRLR014NPBF be used in synchronous rectification applications?

Yes-the integrated body diode has t_rr = 37–56 ns and Q_rr = 48–71 nC at I_F = 6 A, making it suitable for synchronous rectification in buck converters up to ~300 kHz. However, for >500 kHz or ultra-low-loss designs, a dedicated Schottky or GaN FET may offer lower Q_rr.

Is IRLR014NPBF qualified for automotive applications?

No-IRLR014NPBF is an industrial-grade part. For automotive use, Infineon offers the AEC-Q101 qualified AUIRLR014N, which shares identical electrical specs but includes extended temperature screening, failure analysis protocols, and PPAP documentation support.
