Product details

Overview

IRFU024 from Vishay Siliconix is a 60 V, 14 A N-channel power MOSFET in straight-lead (through-hole) IPAK (TO-251) package, featuring 0.10 Ω R_DS(on) at V_GS = 10 V, 25 nC total gate charge, and 91 mJ single-pulse avalanche energy - designed for DC-DC converters, motor control, and industrial power switching where ruggedness and fast switching are required.

For engineers reviewing the IRFU024 datasheet, IRFU024 pinout, IRFU024 application, or IRFU024 equivalent, this page delivers verified electrical specs, thermal derating behavior, body diode recovery characteristics, PCB-mount power dissipation limits (2.5 W), and validated alternative options for through-hole high-current switching designs.

Technical Context

This third-generation TrenchFET® MOSFET uses silicon process optimization to achieve low on-resistance with robust avalanche capability and controlled dV/dt (5.5 V/ns). Its gate threshold voltage (2.0–4.0 V) ensures reliable turn-on with standard 10 V logic-level drivers.

The device integrates a co-packaged body diode with 14 A continuous source-drain current rating, 1.5 V forward voltage at 14 A, and 88–180 ns reverse recovery time - enabling use in freewheeling, synchronous rectification, and unclamped inductive switching circuits without external diodes.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - maximum blocking voltage for 48 V bus systems with margin against transients
R_DS(on)	0.10 Ω @ V_GS = 10 V - enables ≤1.76 W conduction loss at 14 A, critical for thermal management in enclosed enclosures
Q_g	25 nC - determines gate drive power requirement; compatible with low-power PWM controllers like UC384x series
E_AS	91 mJ - supports reliable operation under unclamped inductive load conditions without snubbers
I_D (T_C = 100 °C)	9.0 A - defines usable current in thermally constrained PCB-mount configurations
R_thJA (PCB mount)	50 °C/W - sets junction-to-ambient thermal rise: ΔT_J = 125 °C at 2.5 W ambient-rated dissipation
V_SD	1.5 V @ I_S = 14 A - body diode forward drop impacts efficiency in bidirectional or regenerative topologies

Pinout & Package

IRFU024 uses the IPAK (TO-251) straight-lead through-hole package with three terminals: Gate (G), Drain (D), and Source (S). The drain tab is internally connected to the D lead and serves as the primary heat path; mounting requires mechanical anchoring and thermal via placement beneath the tab.

Pin/Terminal	Circuit Role	Design Meaning
G	Gate control input	High-impedance MOSFET control node; requires <5.8 nC charge to cross threshold; sensitive to ESD
D	Drain (high-side switch node)	Connected to internal die drain and exposed metal tab; carries full load current and dissipates heat into PCB copper
S	Source (return/reference node)	Common reference for gate drive and current sensing; ties to power ground or low-side shunt resistor

Key Features

Feature	Design Value
Dynamic dV/dt rating	5.5 V/ns - suppresses false turn-on during high-speed switching in noisy industrial environments
Fast switching	13 ns turn-on delay + 58 ns rise time - enables >200 kHz PWM operation with minimal overlap loss
Ease of paralleling	Positive temperature coefficient of R_DS(on) - ensures current sharing stability across multiple IRFU024 devices
Simple drive requirements	V_GS(th) = 2.0–4.0 V - compatible with 5 V and 10 V microcontroller outputs without level-shifting
Ruggedized device design	91 mJ E_AS + 56 A pulsed drain current - withstands repetitive inductive kickback in relay/motor drive applications

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
IRFR024	Same silicon die, DPAK (TO-252) surface-mount package; R_thJC = 3.0 °C/W vs. IRFU024's 3.0 °C/W, but R_thJA (PCB) = 50 °C/W same	Requires reflow-compatible layout; unsuitable for hand-soldered prototyping or high-vibration through-hole assemblies	Select IRFR024 only when automated SMT production and thermal pad routing are available.
SiHFU024	Identical IPAK packaging and electrical specs; Pb-free/halogen-free construction per JEDEC J-STD-609A; same 0.10 Ω R_DS(on), 25 nC Q_g, 91 mJ E_AS	No functional difference; qualifies for RoHS-compliant industrial and automotive programs where legacy Pb-based IRFU024 is restricted	Choose SiHFU024 for new designs targeting environmental compliance without circuit or layout changes.

Compared with IRFU024, IRFR024 offers identical performance in a surface-mount form ideal for volume production, while SiHFU024 provides drop-in regulatory compliance - both preserve the same 60 V/14 A switching capability and thermal behavior, but differ in assembly method and material content.

FAQ

What is the maximum continuous drain current for IRFU024 at 100 °C case temperature?

The IRFU024 supports 9.0 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derated value reflects thermal limitations of the IPAK package when mounted on standard FR-4 PCBs, and must be used for thermal design validation instead of the 14 A rating at 25 °C.

Does IRFU024 have avalanche capability, and how is it rated?

Yes, the IRFU024 is rated for single-pulse avalanche energy of 91 mJ under defined test conditions (V_DD = 25 V, I_AS = 14 A, T_J = 25 °C). This capability allows safe operation during inductive load switching events without external protection, provided pulse width and duty cycle remain within datasheet limits.

What is the gate-source threshold voltage range for IRFU024?

The IRFU024 has a gate-source threshold voltage (V_GS(th)) range of 2.0 V to 4.0 V at I_D = 250 μA. This ensures reliable turn-on with standard 5 V or 10 V logic-level drivers while maintaining noise immunity against spurious gate excursions in electrically noisy environments.

Can IRFU024 be used in parallel with other MOSFETs, and why?

Yes, the IRFU024 can be paralleled due to its positive temperature coefficient of R_DS(on). As junction temperature rises, on-resistance increases, promoting natural current balancing across multiple devices - a key advantage for high-current applications like motor phase legs or redundant power stages.

What is the recommended PCB footprint for IRFU024's IPAK (TO-251) package?

Vishay recommends a minimum copper pad area of 0.224" × 0.420" (5.69 mm × 10.67 mm) for the drain tab of IRFU024, with thermal vias spaced ≤2 mm apart and filled or plated to enhance heat transfer to inner layers. The straight leads require 0.055" (1.397 mm) diameter plated-through holes aligned to JEDEC TO-251AA dimensions.
