Product details
Overview
IRFR224TR 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 RDS(on) at VGS = 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 IRFR224TR datasheet, IRFR224TR pinout, IRFR224TR application, or IRFR224TR equivalent, this page delivers verified electrical specs, thermal derating behavior, body diode recovery characteristics, and real-world mounting guidance for PCB layout and thermal management.
Technical Context
This third-generation TrenchFET® MOSFET uses optimized silicon geometry to achieve low on-resistance while maintaining high dV/dt immunity (4.8 V/ns) and robust unclamped inductive switching capability (EAS = 130 mJ). Its gate threshold voltage (2.0–4.0 V) ensures reliable turn-on with standard 10 V logic-level drivers.
The device integrates a fast-recovery body diode (trr = 200–400 ns, Qrr = 0.93–1.9 μC) and exhibits linear SOA up to 100 μs, supporting hard-switched topologies without external snubbers. Thermal resistance from junction-to-case is 3.0 °C/W, enabling high-power operation when mounted on heatsinked PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 250 V - supports input rails up to 200 V DC with margin for transient spikes in industrial SMPS |
| RDS(on) | 1.1 Ω @ VGS = 10 V - enables ≤4.3 W conduction loss at 2.3 A continuous drain current |
| Qg | 14 nC - determines gate drive power requirement; compatible with low-current drivers like TC4427 |
| ID (TC = 100 °C) | 2.4 A - defines maximum sustained current under typical heatsinked PCB conditions |
| EAS | 130 mJ - allows safe operation in unclamped inductive load switching without external protection |
| trr | 200–400 ns - limits reverse recovery losses in synchronous rectification and half-bridge freewheeling |
| RthJC | 3.0 °C/W - confirms efficient heat transfer to external heatsink or copper pour via exposed drain pad |
Pinout & Package
DPAK (TO-252) surface-mount package with exposed drain pad on underside for thermal and electrical connection; 3-pin configuration optimized for high-current routing and low-inductance layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Gate (G) | Control terminal | Receives 10 V logic-level signal; 2.7 nC gate-source charge enables fast turn-on with minimal driver stress |
| Drain (D) | High-side power output | Connected to exposed metal pad; carries full load current and dissipates heat directly to PCB copper or heatsink |
| Source (S) | Reference node / return path | Serves as common reference for gate drive and current sensing; low-inductance source leads reduce switching oscillation |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic dV/dt rating | 4.8 V/ns - prevents false turn-on during high-slew-rate transients in bridge configurations |
| Repetitive avalanche rated | EAR = 4.2 mJ - sustains repeated inductive energy dump without degradation in motor drive commutation |
| Fast switching | td(on) = 7 ns, tr = 13 ns - reduces switching losses in 100–500 kHz DC-DC applications |
| Low Qgd/Qg ratio | 7.8/14 = 56% - improves Miller immunity and enables stable operation with moderate gate resistors |
| Surface-mount (DPAK) | Compatible with vapor-phase and IR reflow - eliminates through-hole assembly cost and supports automated SMT lines |
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 |
|---|---|---|---|
| IRFR220TRPbF | Lower VDS (200 V), lower RDS(on) (0.8 Ω), same DPAK package and pinout | Not suitable for 200+ V bus applications; better for 12–48 V systems requiring lower conduction loss | Select IRFR220TRPbF only if system max VDS < 180 V and thermal budget demands sub-0.85 Ω on-resistance |
| SiHFR224-GE3 | Identical electrical specs and DPAK footprint; differs only in halogen-free material compliance and tape/reel packaging | No functional difference; fully interchangeable in design and layout | Choose SiHFR224-GE3 for RoHS-compliant production runs requiring halogen-free certification per IEC 61249-2-21 |
Compared with IRFR224TR, IRFR220TRPbF trades off voltage rating for lower on-resistance, while SiHFR224-GE3 offers identical performance with updated environmental compliance-making it a drop-in replacement for new designs targeting green manufacturing standards.

FAQ
What is the maximum continuous drain current for IRFR224TR at 100 °C case temperature?
The IRFR224TR supports 2.4 A continuous drain current at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This value reflects thermal derating from the 3.8 A rating at 25 °C and assumes proper PCB copper area per Vishay's recommended DPAK pad layout (Document 72594).
Does IRFR224TR have avalanche capability, and how is it rated?
Yes, the IRFR224TR is repetitively avalanche rated with IAR = 3.8 A and EAR = 4.2 mJ, and single-pulse rated for EAS = 130 mJ. These values are measured under defined test conditions (VDD = 50 V, L = 14 mH, Rg = 25 Ω) and require adherence to junction temperature limits (≤150 °C) for reliability.
What is the gate threshold voltage range for IRFR224TR, and how does it affect drive requirements?
The IRFR224TR has a gate threshold voltage VGS(th) of 2.0–4.0 V at ID = 250 μA. This range ensures turn-on with standard 5 V logic (marginally) but guarantees full enhancement only with ≥10 V gate drive-making it incompatible with 3.3 V microcontrollers without level-shifting or gate boosting.
Can IRFR224TR be used in parallel configurations, and what design considerations apply?
Yes, the IRFR224TR is designed for ease of paralleling due to its positive temperature coefficient of RDS(on), which promotes current sharing. Key considerations include matched gate drive impedance, symmetrical PCB layout, and individual gate resistors (≥10 Ω) to dampen oscillation between paralleled devices.
What is the thermal resistance from junction to ambient for IRFR224TR when mounted on a standard PCB?
When mounted on a 1" square FR-4 PCB, the IRFR224TR has a maximum junction-to-ambient thermal resistance RthJA of 50 °C/W. This value assumes no external heatsink and defines the worst-case temperature rise (ΔT = PD × 50) for board-level thermal design.
