Product details

Overview

IRFR024NPBF from Infineon Technologies (formerly International Rectifier) is a 55 V, 15 A, N-channel enhancement-mode MOSFET in DPAK (TO-252) package with 0.075 Ω R_DS(on) at V_GS = 10 V, optimized for high-efficiency DC-DC conversion and motor drive switching in industrial power supplies.

For engineers reviewing the IRFR024NPBF datasheet, IRFR024NPBF pinout, IRFR024NPBF application, or IRFR024NPBF equivalent, key selection criteria include its low gate charge (Q_g = 18 nC), fast turn-on/turn-off times (t_on = 12 ns, t_off = 25 ns), and avalanche-rated ruggedness for unclamped inductive switching.

Technical Context

This MOSFET employs planar stripe silicon technology with optimized cell pitch and gate oxide thickness to achieve low on-resistance while maintaining robust short-circuit withstand capability. Its threshold voltage (V_GS(th)) ranges from 2.0 V to 4.0 V, enabling reliable gate drive compatibility with 3.3 V and 5 V logic-level controllers.

The device features a fully rated 100% UIS (Unclamped Inductive Switching) test per JEDEC JESD24-11, with E_AS = 92 mJ at T_J = 25 °C, and operates over junction temperature range –55 °C to +175 °C for extended thermal reliability in harsh environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	55 V - Maximum drain-source blocking voltage for 24 V nominal bus applications with 2× safety margin
I_D (continuous)	15 A @ T_C = 25 °C - Sustained current handling with standard heatsinking on PCB copper pour
R_DS(on)	0.075 Ω @ V_GS = 10 V - Enables <1.7 W conduction loss at 15 A, reducing thermal design burden
Q_g	18 nC - Low gate charge minimizes driver power requirement and enables high-frequency PWM operation
t_on/t_off	12 ns / 25 ns - Fast switching supports >500 kHz SMPS designs with reduced switching losses
E_AS	92 mJ @ T_J = 25 °C - Confirmed avalanche energy rating allows safe operation under inductive load transients

Pinout & Package

DPAK (TO-252) surface-mount package with exposed drain pad for enhanced thermal dissipation; thermally efficient for high-current PCB layouts without external heatsink.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Current return path for channel conduction	Connected to power ground plane; low-inductance routing critical for EMI control
Pin 2 (Gate)	Control electrode for channel formation	Requires <100 Ω series resistor to suppress ringing; sensitive to ESD (HBM 2 kV)
Pin 3 (Drain)	Main current output terminal	Internally bonded to large copper tab; must be connected to high-current trace or thermal pad

Key Features

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
STP16NF55	R_DS(on) = 0.085 Ω @ 10 V; Q_g = 22 nC; TO-220 package	Higher thermal resistance (R_θJC = 1.5 °C/W vs. 1.0 °C/W) limits continuous current in compact PCBs	Prefer when through-hole assembly or higher single-pulse surge current (>30 A) is required
DMN3025LSD-13	R_DS(on) = 0.035 Ω @ 4.5 V; SO-8 package; logic-level gate	Lower voltage rating (30 V) restricts use to ≤12 V systems; not suitable for 24 V bus applications	Prefer for space-constrained 5 V/12 V logic-driven loads where ultra-low R_DS(on) outweighs voltage margin

Compared with STP16NF55 and DMN3025LSD-13, IRFR024NPBF delivers optimal balance of 55 V rating, DPAK thermal performance, and 10 V gate drive compatibility-making it the preferred choice for industrial 24 V power stages requiring both efficiency and ruggedness.

FAQ

What is the maximum recommended gate-source voltage for IRFR024NPBF?

The absolute maximum V_GS is ±20 V per datasheet. Operation above +12 V provides minimal R_DS(on) reduction but increases gate oxide stress risk. For reliable long-term operation, +10 V is the standard drive voltage, delivering full rated current with margin against transient overshoot.

Does IRFR024NPBF require a gate resistor, and what value is recommended?

Yes-a 10–47 Ω series gate resistor is recommended to dampen parasitic oscillation and limit peak gate current. A 22 Ω resistor balances switching speed (t_on/t_off ~15–30 ns) with EMI suppression and driver IC protection, especially in high-di/dt half-bridge configurations.

Can IRFR024NPBF be used in parallel configurations?

Yes, but only with matched units and symmetrical PCB layout. Its positive temperature coefficient of R_DS(on) enables inherent current sharing above 100 °C junction temperature. Layout must ensure identical gate and source loop inductances (<0.5 nH difference) to avoid dynamic imbalance.

Is IRFR024NPBF qualified for automotive applications per AEC-Q101?

No-IRFR024NPBF is not AEC-Q101 qualified. It meets industrial-grade reliability standards (JESD22-A108, JESD22-A110), but lacks the extended temperature cycling, humidity bias HAST, and failure analysis reporting required for automotive qualification. Use AUIRF1310S or similar AEC-Q101 parts for automotive designs.
