Product details

Overview

IRFR224TRLPBF from Vishay Siliconix is a 250 V, 3.8 A N-channel surface-mount power MOSFET in DPAK (TO-252) package, featuring 1.1 Ω R_DS(on) at V_GS = 10 V, 14 nC total gate charge, and repetitive avalanche rating-designed for DC-DC converters, motor control, and industrial power switching where ruggedness and fast switching are required.

For engineers reviewing the IRFR224TRLPBF datasheet, IRFR224TRLPBF pinout, IRFR224TRLPBF application, or IRFR224TRLPBF equivalent, this part supports high-reliability unclamped inductive switching, offers dV/dt immunity up to 4.8 V/ns, and delivers 130 mJ single-pulse avalanche energy-key selection criteria for hard-switched flyback, solenoid drivers, and overvoltage-protected SMPS designs.

Technical Context

This third-generation TrenchFET® MOSFET uses optimized silicon geometry to achieve low conduction loss while maintaining robust avalanche capability. Its 1.1 Ω on-resistance at 10 V gate drive enables efficient operation in 12–48 V input systems, and its 14 nC gate charge supports switching frequencies up to several hundred kHz without excessive driver losses.

The device integrates a fast-recovery body diode with 200–400 ns reverse recovery time and 0.93–1.9 μC Q_rr, enabling synchronous rectification replacement in low-side configurations. Thermal resistance of 3.0 °C/W (junction-to-case) allows direct heatsinking in compact PCB layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	250 V - supports 200 V DC bus applications with 25 % safety margin
R_DS(on)	1.1 Ω @ V_GS = 10 V - limits I²R loss to ≤10 W at 3 A continuous drain current
Q_g	14 nC - determines gate driver current requirement (~1.4 mA avg. at 100 kHz, 10 V swing)
I_D (T_C = 25 °C)	3.8 A - usable in thermally constrained SMT layouts with minimal copper area
E_AS	130 mJ - withstands unclamped inductive energy in relay/solenoid snubberless designs
dV/dt Rating	4.8 V/ns - suppresses false turn-on in high-noise motor drive and industrial PLC outputs
R_thJC	3.0 °C/W - enables direct thermal pad mounting to external heatsink for >25 W dissipation

Pinout & Package

DPAK (TO-252) package with exposed thermal pad on underside; standard 3-pin surface-mount footprint compatible with vapor-phase and infrared reflow. Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Gate (G)	Control electrode	Accepts 10 V logic-level drive; threshold voltage 2.0–4.0 V ensures reliable turn-on with standard microcontroller GPIO
Drain (D)	High-side power terminal	Connected to internal die backside; electrically tied to exposed metal tab-must be isolated from heatsink unless referenced to same potential
Source (S)	Return path and reference node	Serves as common return for gate drive and load current; low-inductance layout critical for minimizing switching overshoot

Key Features

Feature	Design Value
Repetitive avalanche rated	Enables reliable operation under transient overcurrent without derating or external clamping in inductive loads
Dynamic dV/dt rating	4.8 V/ns immunity prevents spurious turn-on during fast bus transients in motor drives and industrial I/O
Fast switching with low Q_g	14 nC total gate charge reduces driver power loss and enables <50 ns turn-off delay in hard-switched topologies
Surface-mount DPAK package	TO-252 outline supports automated assembly and provides 3.0 °C/W junction-to-case thermal path for board-level heatsinking
Low R_DS(on) × Q_g figure of merit	1.54 Ω·nC - balances conduction and switching loss for high-efficiency 100–300 kHz DC-DC stages

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
IRFR220TRLPBF	Lower V_DS (200 V), higher R_DS(on) (1.5 Ω), same DPAK package and pinout	Not suitable for 200+ V bus applications; limited to ≤150 V DC systems	Select only when lower voltage rating and reduced cost justify trade-off in conduction loss and avalanche margin
SiHFR224-GE3	Identical electrical specs and DPAK package; RoHS-compliant with matte tin lead finish vs. IRFR224TRLPBF's Pb-free annealed finish	No functional difference; qualified for same industrial temperature range (−55 to +150 °C)	Preferred for new designs requiring full Vishay Green standard compliance and long-term supply continuity

Compared with IRFR224TRLPBF, IRFR220TRLPBF sacrifices 50 V blocking and increases conduction loss by 36 %, while SiHFR224-GE3 matches all key parameters but offers enhanced environmental compliance-making it the drop-in alternative for future-proofed industrial designs.

FAQ

What is the maximum continuous drain current for IRFR224TRLPBF at 100 °C case temperature?

The maximum continuous drain current for IRFR224TRLPBF is 2.4 A at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the DPAK package under sustained high-temperature operation and must be verified against actual PCB copper area and ambient conditions in final layout.

Does IRFR224TRLPBF have a built-in body diode, and what are its key characteristics?

Yes, IRFR224TRLPBF integrates a parasitic body diode with typical forward voltage of 1.8 V at 3.8 A and reverse recovery time of 200–400 ns. Its Q_rr is 0.93–1.9 μC, supporting moderate-frequency freewheeling in low-side switch configurations without external diode supplementation.

Is IRFR224TRLPBF suitable for logic-level gate drive applications?

No-IRFR224TRLPBF has a gate threshold voltage range of 2.0–4.0 V and requires 10 V for full enhancement (R_DS(on) = 1.1 Ω). It is not a logic-level MOSFET; for 3.3 V or 5 V microcontroller drive, consider Vishay's Si2300 or similar logic-compatible devices instead of IRFR224TRLPBF.

What is the thermal resistance from junction to ambient for IRFR224TRLPBF in standard PCB mount?

When mounted on a 1" square FR-4 PCB, IRFR224TRLPBF has a maximum junction-to-ambient thermal resistance (R_thJA) of 50 °C/W. This value assumes minimal copper area; adding thermal vias and copper pour can improve heat dissipation, but datasheet limits remain valid for design margining.

Can IRFR224TRLPBF replace IRFU224PbF in an existing through-hole design?

No-IRFR224TRLPBF uses DPAK (TO-252) surface-mount packaging, while IRFU224PbF uses IPAK (TO-251) through-hole packaging. Their footprints, soldering methods, and mechanical mounting are incompatible; direct replacement would require PCB redesign and is not recommended without full thermal and layout validation of IRFR224TRLPBF.
