Product details

Overview

IRFR224TRL 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 IRFR224TRL datasheet, IRFR224TRL pinout, IRFR224TRL application, or IRFR224TRL equivalent, this page delivers verified electrical specs, thermal derating behavior, body diode recovery characteristics, and direct-mount PCB layout guidance per Vishay's recommended DPAK pad dimensions.

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 unclamped inductive switching capability. Its 1.1 Ω R_DS(on) and 14 nC Q_g support efficient hard-switching up to ~100 kHz in medium-power SMPS topologies.

The device integrates a robust intrinsic body diode with 200–400 ns reverse recovery time and 0.93–1.9 μC Q_rr, enabling synchronous rectification and freewheeling operation without external Schottky supplementation in many 24–48 V systems.

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
IRFR220PbF	200 V V_DS, 4.2 A I_D, 0.8 Ω R_DS(on) - lower voltage rating but lower on-resistance	Not suitable for 200+ V bus applications; preferred in 12–48 V DC-DC where lower R_DS(on) improves efficiency	Select IRFR220PbF only if system maximum V_DS stress remains below 160 V and lower conduction loss is prioritized over voltage margin.
SiHFR224-GE3	Identical V_DS, R_DS(on), Q_g, and package; Vishay's newer halogen-free variant with same die and DPAK footprint	No functional difference; fully interchangeable in new designs requiring RoHS-compliant materials	SiHFR224-GE3 is a direct material-compliance upgrade; IRFR224TRL remains valid for legacy BOMs and Pb-free process lines.

Compared with IRFR224TRL, IRFR220PbF trades voltage headroom for lower conduction loss in low-voltage systems, while SiHFR224-GE3 offers identical electrical performance with updated environmental compliance - neither requires PCB layout changes, but only SiHFR224-GE3 is halogen-free.

FAQ

What is the maximum continuous drain current for IRFR224TRL at 100 °C case temperature?

The IRFR224TRL supports 2.4 A continuous drain current at T_C = 100 °C, derived from its 3.8 A rating at 25 °C and linear derating factor of 0.33 W/°C. This value assumes proper PCB copper area per Vishay's DPAK mounting guidelines and accounts for thermal resistance from junction to case (R_thJC = 3.0 °C/W).

Does IRFR224TRL require a gate driver for microcontroller-level PWM control?

IRFR224TRL has a gate threshold voltage range of 2.0–4.0 V and is specified for 10 V gate drive, so direct connection to 3.3 V or 5 V GPIO is insufficient for full enhancement. A gate driver (e.g., TC4420 or similar) is required to deliver ≥10 V and sufficient peak current to charge its 14 nC gate capacitance within nanoseconds and avoid linear-mode heating.

Can IRFR224TRL be used in avalanche mode repeatedly without degradation?

Yes - IRFR224TRL is explicitly rated for repetitive avalanche operation with I_AR = 3.8 A and E_AR = 4.2 mJ per pulse, provided pulse width and duty cycle remain within limits defined by maximum junction temperature (150 °C). Data sheet Figure 11 provides the safe operating area under repetitive avalanche conditions.

What is the recommended PCB pad layout for IRFR224TRL's DPAK package?

Vishay recommends a minimum 0.224" × 0.420" (5.69 × 10.67 mm) copper pad for the drain tab of IRFR224TRL, with thermal vias to inner layers. The Application Note 826 document specifies exact dimensions and spacing to ensure mechanical reliability and optimal thermal transfer - critical for sustaining 2.5 W dissipation on FR-4 boards.

How does the body diode performance of IRFR224TRL compare to discrete Schottky diodes?

The IRFR224TRL's integrated body diode has V_SD = 1.8 V at 3.8 A and t_rr = 200–400 ns, making it slower and higher-drop than most Schottky diodes (typically 0.4–0.6 V, <50 ns t_rr). However, its Q_rr of 0.93–1.9 μC is well-characterized and enables predictable snubberless operation in low-frequency freewheeling - unlike Schottky diodes, it avoids thermal runaway at elevated temperatures.
