Product details

Overview

IRFR3504ZTRL from Infineon Technologies (formerly International Rectifier) is an N-channel automotive-grade HEXFET® Power MOSFET in D-Pak (TO-252) package, rated for 40V V_DSS, 9.0 mΩ R_DS(on) at V_GS = 10V, and 42A continuous drain current at T_C = 25°C. It features 175°C maximum junction temperature, fast switching (t_r = 74 ns, t_f = 38 ns), and rated repetitive avalanche capability - deployed in engine control units, DC-DC converters, and high-side load switches.

For engineers reviewing the IRFR3504ZTRL datasheet, IRFR3504ZTRL pinout, IRFR3504ZTRL application, or IRFR3504ZTRL equivalent, key selection criteria include its low R_DS(on) at 10V gate drive, robust avalanche energy rating (E_AS = 310 mJ), thermal performance (R_θJC = 1.66°C/W), and AEC-Q101 qualification for under-hood automotive power stages.

Technical Context

This MOSFET employs advanced planar silicon processing to minimize on-resistance per die area while maintaining ruggedness. Its integral body diode supports synchronous rectification and unclamped inductive switching, with verified reverse recovery charge (Q_rr = 9.2–14 nC) and trr = 18–27 ns at I_F = 42A.

The device operates with gate threshold voltage (V_GS(th)) between 2.0 V and 4.0 V, enabling compatibility with 3.3 V and 5 V logic-level drivers when used with appropriate gate resistance (R_G = 15 Ω typical test condition). Total gate charge (Q_g = 30–45 nC) and Miller charge (Q_gd = 12 nC) are optimized for high-frequency PWM control up to several hundred kHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40 V - Maximum blocking voltage before avalanche; suitable for 12 V/24 V automotive battery systems with transient margin.
R_DS(on)	9.0 mΩ max @ V_GS = 10 V, T_J = 25°C - Enables <1 W conduction loss at 33 A, critical for thermally constrained ECUs.
I_D (cont)	42 A @ T_C = 25°C - Sustains peak motor drive or solenoid currents without derating in heatsinked D-Pak layout.
E_AS	310 mJ - Single-pulse avalanche energy rating ensures survivability during inductive turn-off transients in relay or actuator drives.
t_r/t_f	74 ns / 38 ns - Fast edge rates reduce switching losses in 100–500 kHz DC-DC topologies with minimal EMI filtering burden.
T_J(max)	175°C - Enables operation in under-hood environments where ambient exceeds 125°C with proper thermal design.
Q_g	45 nC max - Determines gate driver current requirement (~3 mA avg. at 100 kHz, 10 V swing); impacts driver IC selection.

Pinout & Package

IRFR3504ZTRL uses the surface-mount D-Pak (TO-252AA) package with exposed drain pad for thermal enhancement. The three-terminal configuration supports high-current PCB routing and direct heatsinking via the drain tab.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Power return path and gate reference	Connected to system ground or low-side switch node; carries full load current and defines V_GS reference.
Pin 2 (Gate)	Control input	High-impedance MOS gate requiring <200 nA leakage; driven by logic-level or dedicated gate driver with R_G = 15 Ω typical.
Pin 3 (Drain)	Power output terminal	Internally bonded to exposed copper pad; must be soldered to large copper pour or heatsink for R_θJC = 1.66°C/W performance.

Key Features

Feature	Design Value
Ultra-low R_DS(on)	9.0 mΩ enables >96% efficiency in 12 V, 30 A load switch applications with <1 W conduction loss.
175°C junction rating	Supports operation in engine bay locations where case temperatures reach 150°C without derating.
Repetitive avalanche rated	Validated for repeated unclamped inductive switching up to T_Jmax, eliminating need for external snubbers in solenoid drivers.
Fast body diode	trr = 18–27 ns and Q_rr = 9.2–14 nC allow use in synchronous buck converters without significant shoot-through risk.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N4F7AG	40 V, 2.2 mΩ R_DS(on), PowerFLAT 5x6 package, lower R_θJA but no AEC-Q101 documentation in public datasheet	Higher current density; requires tighter layout control due to smaller footprint and higher thermal flux	Select when board space is constrained and thermal interface to PCB is highly optimized.
ON Semiconductor NTMFS4C09NT1G	40 V, 9.0 mΩ R_DS(on), SO-8FL package, AEC-Q101 qualified, 30 A I_D rating (lower than IRFR3504ZTRL's 42 A)	Limited to lower-current loads; SO-8FL has higher R_θJC (2.5°C/W) than D-Pak	Choose for cost-sensitive, space-constrained modules where 30 A peak suffices and D-Pak assembly is not feasible.

Compared with STL220N4F7AG and NTMFS4C09NT1G, IRFR3504ZTRL offers the highest continuous current (42 A) and lowest published thermal resistance (1.66°C/W) in a widely supported D-Pak footprint, making it optimal for thermally demanding, high-reliability automotive power stages where proven AEC-Q101 validation and field history are required.

FAQ

Is IRFR3504ZTRL AEC-Q101 qualified?

Yes. IRFR3504ZTRL is explicitly qualified to AEC-Q101 Rev D for automotive applications, including stress testing for temperature cycling, humidity bias HAST, and unclamped inductive switching. Qualification data is documented in Infineon's official automotive reliability report for this part number.

What is the recommended gate resistor value for 200 kHz PWM operation?

For 200 kHz switching with minimal overshoot and EMI, a 10 Ω series gate resistor is recommended. This balances rise/fall time (targeting ~50 ns) against gate driver current capability and ringing suppression, based on measured Q_g = 38 nC and C_iss = 1510 pF at V_DS = 10 V.

Can IRFR3504ZTRL be used in a synchronous buck converter without an external Schottky diode?

Yes. Its body diode has trr = 18–27 ns and Q_rr = 9.2–14 nC, enabling reliable synchronous rectification at ≤300 kHz. However, dead-time must be carefully tuned (≥100 ns) to prevent shoot-through, especially at light loads where V_GS threshold variation affects turn-on timing.

Does the D-Pak package require thermal vias under the drain pad?

Yes. To achieve the specified R_θJC = 1.66°C/W, at least nine 0.3 mm diameter thermal vias (filled or plated) must connect the exposed drain pad to an internal or backside ground plane. Without vias, R_θJA degrades to ~40°C/W, limiting usable current to ~12 A at 70°C ambient.
