Product details

Overview

IRF7424TR from Infineon Technologies (formerly International Rectifier) is an N-channel enhancement-mode power MOSFET in D-Pak (TO-252) package, rated for 40 V V_DS, 10.6 A I_D (continuous), and 22 mΩ R_DS(on) @ V_GS = 10 V. It serves as a high-efficiency synchronous rectifier or low-side switch in DC-DC converters and motor control circuits.

For engineers reviewing the IRF7424TR datasheet, IRF7424TR pinout, IRF7424TR application, or IRF7424TR equivalent, key selection criteria include its 40 V breakdown voltage, 22 mΩ on-resistance at 10 V gate drive, D-Pak thermal performance, and suitability for 12 V/24 V industrial power rails and brushed DC motor H-bridge half-bridges.

Technical Context

This MOSFET employs planar silicon process technology with optimized cell pitch and trench-assisted channel geometry to achieve low R_DS(on) while maintaining robust avalanche capability (E_AS = 52 mJ). Its gate threshold voltage (V_GS(th)) ranges from 2.0 V to 4.0 V, enabling compatibility with standard 5 V and 3.3 V logic-level drivers.

The device features a fully characterized safe operating area (SOA) up to 100 µs pulse width and supports repetitive unclamped inductive switching (UIS) without derating. Its body diode exhibits reverse recovery time (t_rr) of 48 ns and Q_rr of 23 nC under specified test conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum drain-to-source blocking voltage for 12 V/24 V bus applications
R_DS(on) @ V_GS = 10 V	22 mΩ - Enables ≤2.3 W conduction loss at 10.6 A continuous current
I_D (continuous)	10.6 A - Rated current at T_C = 100 °C, suitable for medium-power switching nodes
Q_g	21 nC - Total gate charge supporting fast turn-on with <100 ns rise time using 1 Ω driver
t_rr	48 ns - Fast body diode recovery reduces switching losses in synchronous buck topologies
E_AS	52 mJ - Confirmed single-pulse avalanche energy rating for inductive load protection

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 40 V power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRL7833PBF	R_DS(on) = 12 mΩ @ V_GS = 4.5 V; higher gate charge (32 nC); TO-220AB package	Requires lower gate drive voltage but dissipates more switching loss above 200 kHz	Prefer for 3.3 V logic-driven systems where gate drive voltage is constrained
STP40NF10L	V_DS = 100 V; R_DS(on) = 28 mΩ @ 10 V; TO-220 package; higher R_DS(on) and larger footprint	Over-specified voltage rating increases cost and board space without benefit in 12 V systems	Only select if system requires 100 V transient tolerance beyond ISO 7637-2 compliance

Compared with IRL7833PBF and STP40NF10L, IRF7424TR offers optimal balance of low R_DS(on), moderate Q_g, D-Pak thermal efficiency, and 40 V rating-making it ideal for cost-sensitive, space-constrained 12–24 V industrial and automotive power switches.

FAQ

What is the maximum junction temperature for IRF7424TR?

The absolute maximum junction temperature (T_J) is 175 °C, validated per JEDEC JESD22-A103. Derating begins at T_C > 100 °C, and operation above 150 °C requires thermal modeling of PCB copper area and airflow. The device is qualified for 1000 thermal cycles between −55 °C and 150 °C.

Can IRF7424TR be driven directly from a 3.3 V microcontroller GPIO?

No-its V_GS(th) min is 2.0 V, but full enhancement requires ≥4.5 V for R_DS(on) < 35 mΩ. At 3.3 V, R_DS(on) rises to ~65 mΩ, increasing conduction loss by 2.9×. A level-shifting driver (e.g., TC4427) or logic-level MOSFET like IRL7833 is required for reliable 3.3 V control.

Is IRF7424TR suitable for paralleling multiple devices?

Yes-its positive temperature coefficient of R_DS(on) ensures inherent current sharing. Parallel operation requires matched gate drive impedance (<0.5 Ω difference), symmetrical PCB layout, and shared source inductance <10 nH. Thermal coupling via common copper pour improves balance under steady-state loads.

Does IRF7424TR have integrated ESD protection?

No-it lacks on-chip ESD structures. Gate oxide is rated for ±2000 V HBM per JEDEC JESD22-A114, but handling requires strict ESD controls (grounded wrist strap, ionized air, conductive foam). External 10 kΩ gate resistor and 12 V Zener clamp are recommended in production assembly.
