Product details

Overview

IRFR4104TRL 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, 58 A I_D (T_C = 25°C), and 9.5 mΩ R_DS(on) max at V_GS = 10 V. It serves as a high-efficiency synchronous rectifier or low-side switch in DC-DC converters and motor drive half-bridges.

For engineers reviewing the IRFR4104TRL datasheet, IRFR4104TRL pinout, IRFR4104TRL application, or IRFR4104TRL equivalent, key selection criteria include its 40 V breakdown voltage, 9.5 mΩ on-resistance at 10 V gate drive, D-Pak thermal performance, and suitability for 25–50 kHz switching in industrial power supplies and BLDC controllers.

Technical Context

This MOSFET uses planar silicon process with optimized cell pitch and trench-assisted channel geometry to achieve low R_DS(on) × Q_g figure-of-merit. Its gate threshold voltage (V_GS(th)) is specified between 2.0 V and 4.0 V, enabling compatibility with standard 5 V and 3.3 V logic-level drivers.

The device features fully avalanche-rated operation (E_AS = 170 mJ), non-punch-through (NPT) drift region design, and guaranteed 100% UIS testing per JEDEC JESD22-A109. It is not logic-level optimized - minimum recommended V_GS for full enhancement is 10 V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum drain-source blocking voltage; sets upper limit for bus voltage in buck converters and half-bridge legs.
R_DS(on) max	9.5 mΩ @ V_GS = 10 V - Directly determines conduction loss in high-current paths; enables <1.5 W dissipation at 40 A continuous.
I_D (T_C = 25°C)	58 A - Continuous drain current rating under ideal heatsink conditions; derates to ~35 A at T_C = 100°C.
Q_g	52 nC - Total gate charge; defines driver strength requirement and switching energy loss at 100 kHz PWM.
E_AS	170 mJ - Single-pulse avalanche energy rating; supports robustness against inductive turn-off transients in relay/motor drive circuits.
V_GS(th)	2.0–4.0 V - Gate threshold range; confirms turn-on begins below 5 V but full enhancement requires ≥10 V drive.

Pinout & Package

IRFR4104TRL is housed in a surface-mount D-Pak (TO-252AA) package with exposed drain pad for thermal relief. The package has three terminals: Gate (G), Drain (D), and Source (S), with Drain electrically connected to the metal tab.

Pin/Terminal	Circuit Role	Design Meaning
G	Gate	Controls channel formation; requires 10 V drive for minimal R_DS(on); Miller plateau occurs near 3.5 V.
D	Drain	Main high-side current path; internally bonded to exposed copper pad for PCB heat sinking.
S	Source	Reference node for gate drive; connects to power ground plane; source inductance impacts switching speed.

Key Features

Feature	Design Value
100% UIS tested	Guarantees ruggedness against unclamped inductive switching events without derating.
Enhanced body diode recovery	Reduces reverse recovery charge (Q_rr = 120 nC), lowering EMI and cross-conduction loss in synchronous rectification.
Lead-free and RoHS compliant	Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1); suitable for lead-free reflow assembly.
Optimized for hard-switched topologies	Low output capacitance (C_oss = 1900 pF) and gate-drain charge (Q_gd = 18 nC) reduce turn-off delay and overlap loss.

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
STP40NF10L	R_DS(on) = 11.5 mΩ @ 10 V; higher Q_g (65 nC); TO-220 package	Larger footprint and lower thermal conductivity than D-Pak; less suitable for dense SMT layouts	Prefer when through-hole mounting or legacy board compatibility required
IXTP40N10P	R_DS(on) = 10.5 mΩ @ 10 V; TO-220FP package; lower E_AS (120 mJ)	Reduced avalanche margin; same thermal resistance but taller profile limits airflow	Choose only if existing thermal design accommodates vertical height and lower transient robustness

Compared with STP40NF10L and IXTP40N10P, IRFR4104TRL offers superior thermal performance in SMT space-constrained designs, lowest R_DS(on) among the three, and highest guaranteed avalanche energy - critical for motor and inductive load reliability.

FAQ

Is IRFR4104TRL a logic-level MOSFET?

No. IRFR4104TRL is a standard-gate MOSFET requiring 10 V for full enhancement. Its V_GS(th) range (2.0–4.0 V) allows partial turn-on at 5 V, but R_DS(on) rises sharply below 8 V - it is not rated or characterized for reliable operation with 3.3 V or 5 V gate drive alone.

What is the maximum junction temperature for continuous operation?

The absolute maximum junction temperature is 175°C. For continuous operation, thermal design must ensure T_J remains ≤175°C under worst-case ambient, power dissipation, and PCB copper area conditions. Derated current ratings assume T_C = 25°C to 100°C per datasheet curves.

Can IRFR4104TRL be used in parallel configurations?

Yes, but with careful layout: matched gate resistors (≤1 Ω), symmetrical source inductance, and shared thermal mass are required. Its positive temperature coefficient of R_DS(on) supports current sharing, but gate drive skew must be minimized to avoid dynamic imbalance during switching transitions.

Does IRFR4104TRL have integrated ESD protection?

No. IRFR4104TRL lacks on-chip ESD protection diodes. External gate protection (e.g., 12 V Zener clamp from G to S) is recommended during handling and in systems exposed to human contact or cable discharge events per IEC 61000-4-2 Level 2+.
