Product details

Overview

IRLU024PBF from Vishay Siliconix is a logic-level N-channel power MOSFET in IPAK (TO-251) through-hole package, rated for 60 V V_DS, 14 A continuous drain current at T_C = 25 °C, and R_DS(on) = 0.10 Ω at V_GS = 5 V. It delivers fast switching with 18 nC total gate charge and supports unclamped inductive switching up to 53 mJ, making it suitable for DC-DC converters, motor drivers, and load-switching circuits.

For engineers reviewing the IRLU024PBF datasheet, IRLU024PBF pinout, IRLU024PBF application, or IRLU024PBF equivalent, key selection criteria include its logic-level gate drive compatibility (V_GS(th) = 1.0–2.0 V), low R_DS(on) at 4 V/5 V, avalanche ruggedness, thermal resistance (R_thJC = 3.0 °C/W), and TO-251 mechanical footprint for through-hole PCB mounting.

Technical Context

This third-generation power MOSFET uses planar V-groove technology to achieve optimized dV/dt immunity and robust avalanche performance. Its gate threshold voltage range (1.0–2.0 V) ensures reliable turn-on with standard 3.3 V or 5 V logic controllers, while the integral body diode supports synchronous rectification and freewheeling in inductive loads.

The device features low gate charge (Q_g = 18 nC, Q_gd = 12 nC) and fast switching times (t_r = 110 ns, t_f = 41 ns) under standardized test conditions (V_DD = 30 V, R_g = 9.0 Ω). Thermal design is supported by a low junction-to-case resistance of 3.0 °C/W and defined PCB-mount derating (2.5 W at T_A = 25 °C).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Maximum blocking voltage for 24 V and 48 V bus applications
R_DS(on) @ V_GS = 5 V	0.10 Ω - Enables ≤1.2 W conduction loss at 14 A, critical for thermal management
Q_g	18 nC - Determines gate driver current requirement (~1.8 mA avg. for 100 kHz switching)
I_D (continuous)	14 A @ T_C = 25 °C - Supports high-current load switching without forced cooling
E_AS	53 mJ - Specifies single-pulse avalanche energy handling for inductive turn-off stress
R_thJC	3.0 °C/W - Enables direct heatsink attachment for high-power dissipation
V_GS(th)	1.0–2.0 V - Ensures full enhancement with 3.3 V microcontroller GPIOs

Pinout & Package

IRLU024PBF uses the IPAK (TO-251) through-hole package with three terminals: Gate (G), Drain (D), and Source (S). The drain tab is internally connected to the die substrate and serves as the primary thermal path; the package is designed for vertical mounting with axial lead insertion and soldering to plated-through holes.

Pin/Terminal	Circuit Role	Design Meaning
G	Gate control input	Accepts logic-level voltage (≥4 V) to fully enhance channel; requires <100 nA leakage current budget
D	Drain (high-side switch node)	High-current output terminal; electrically and thermally connected to metal tab for heatsinking
S	Source (return path)	Reference node for gate drive; connects to ground or low-side return in common-source configuration

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS = 4 V, compatible with 3.3 V and 5 V MCU outputs without level-shifting
Dynamic dV/dt rating	Rated for 4.5 V/ns peak di/dt-induced voltage transients, reducing false turn-on risk in noisy environments
Fast switching	110 ns rise time and 41 ns fall time enable >500 kHz PWM operation with minimal switching loss
Avalanche ruggedness	Specified single-pulse E_AS = 53 mJ allows safe operation during inductive load interruption without snubbers
Low R_DS(on) at low V_GS	R_DS(on) = 0.14 Ω at V_GS = 4 V enables efficient operation in battery-powered systems with weak gate drive

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
IRLR024PBF	Same silicon die, DPAK (TO-252) surface-mount package; R_thJA = 50 °C/W (PCB mount) vs. IRLU024PBF's 110 °C/W	Preferred for automated SMT assembly; unsuitable for through-hole-only designs or manual prototyping	Select IRLR024PBF only when board layout supports DPAK footprint and reflow capability exists
STP16NF06L	60 V, 16 A, R_DS(on) = 0.12 Ω @ V_GS = 5 V; TO-220 package; higher Q_g = 22 nC	Better current rating but larger footprint and slower switching; lacks specified dV/dt rating	Choose STP16NF06L only when higher current headroom is required and thermal mass from TO-220 is acceptable

Compared with IRLU024PBF, IRLR024PBF offers identical electrical specs but requires SMT process compatibility, while STP16NF06L trades faster switching and smaller size for higher gate drive demand and no dV/dt immunity guarantee-making IRLU024PBF optimal for space-constrained through-hole designs needing rugged, logic-level operation.

FAQ

What is the maximum continuous drain current for IRLU024PBF at 100 °C case temperature?

The IRLU024PBF supports 9.2 A continuous drain current at T_C = 100 °C, derived from its 14 A rating at 25 °C and linear derating factor of 0.33 W/°C. This value reflects thermal limits under sustained conduction with adequate heatsinking, and must be validated against actual board layout and ambient conditions in the final design.

Does IRLU024PBF have a specified avalanche energy rating?

Yes, IRLU024PBF has a single-pulse avalanche energy rating (E_AS) of 53 mJ, measured under standardized conditions (V_DD = 25 V, I_AS = 14 A, T_J = 25 °C). This parameter quantifies its ability to absorb inductive energy during unclamped inductive switching events without failure.

What is the gate-source threshold voltage range for IRLU024PBF?

The gate-source threshold voltage (V_GS(th)) for IRLU024PBF is specified from 1.0 V to 2.0 V at I_D = 250 μA and T_J = 25 °C. This range confirms reliable turn-on with 3.3 V logic signals and provides margin against noise-induced false triggering in real-world PCB environments.

Can IRLU024PBF be used with 4 V gate drive?

Yes, IRLU024PBF is explicitly characterized at V_GS = 4 V, where R_DS(on) is guaranteed ≤ 0.14 Ω at I_D = 7.0 A. Its logic-level design ensures full enhancement well below 5 V, making it suitable for battery-powered systems or microcontrollers with limited I/O voltage swing.

What is the thermal resistance from junction to case (R_thJC) for IRLU024PBF?

The maximum junction-to-case thermal resistance (R_thJC) for IRLU024PBF is 3.0 °C/W, measured from the die junction to the drain tab. This low value enables effective heat transfer to an external heatsink when the metal tab is mounted directly to a thermally conductive surface using thermal interface material.
