Product details

Overview

IRLR3714TRLPBF from Infineon Technologies (formerly International Rectifier) is a 20 V, 36 A N-channel enhancement-mode Power MOSFET in D-Pak package, optimized for high-frequency synchronous rectification in isolated DC-DC converters and buck regulators. It features 20 mΩ R_DS(on) at V_GS = 4.5 V, ultra-low gate charge (Q_g = 6.5–9.7 nC), and fully characterized avalanche capability (E_AS = 72 mJ), enabling efficient 48 V-to-12 V/5 V telecom power stages.

For engineers reviewing the IRLR3714TRLPBF datasheet, IRLR3714TRLPBF pinout, IRLR3714TRLPBF application, or IRLR3714TRLPBF equivalent, key selection criteria include its low-voltage gate drive compatibility (4.5 V logic-level turn-on), robust body diode recovery (t_rr = 35–53 ns), thermal performance (R_θJC = 3.2 °C/W), and suitability for space-constrained industrial and telecom SMPS designs.

Technical Context

This HEXFET device uses planar stripe cell structure with optimized gate oxide thickness to achieve stable threshold voltage (V_GS(th) = 1.0–3.0 V) and low on-resistance temperature coefficient (0.022 V/°C). Its dynamic parameters-including Q_gd = 2.9 nC and C_rss = 68 pF-are tuned for fast switching with minimal Miller-induced shoot-through risk in synchronous buck topologies.

The integrated body diode exhibits low forward voltage (V_SD = 0.88 V @ 18 A, T_J = 125°C) and controlled reverse recovery (Q_rr = 34–53 nC), supporting zero-voltage switching (ZVS) operation in resonant converters and reducing EMI in high-dV/dt environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	20 V - Supports input rails up to 16 V DC with 20 % margin; suitable for 12 V and 5 V output stages.
R_DS(on) max	20 mΩ @ V_GS = 4.5 V - Enables <1 W conduction loss at 30 A, critical for high-current CPU VRMs.
Q_g	6.5–9.7 nC - Reduces gate driver power demand and enables >1 MHz switching without excessive driver heating.
t_rr	35–53 ns - Limits diode reverse recovery energy loss and prevents cross-conduction in synchronous rectifiers.
E_AS	72 mJ - Withstands unclamped inductive switching events in hard-switched flyback or forward converters.
R_θJC	3.2 °C/W - Allows 33 W continuous dissipation at T_C = 70°C with minimal heatsinking in D-Pak footprint.
I_D @ 25°C	36 A - Sustains peak load currents in server VRMs and PoE PDs without derating at ambient temperatures ≤50°C.

Pinout & Package

D-Pak (TO-252AA) surface-mount package with exposed drain pad for thermal and electrical connection. Standard 3-pin configuration: Gate (G), Drain (D), Source (S).

Pin/Terminal	Circuit Role	Design Meaning
G	Control electrode	Accepts 4.5 V logic-level drive; requires <10 nC to switch 14 A with <10 ns delay (t_d(on) = 8.7 ns).
D	Main current path anode	Connected to PCB copper pour for thermal transfer; electrically tied to source of synchronous rectifier stage.
S	Main current path cathode / reference node	Serves as return path for load current and gate drive loop; low-inductance layout essential for EMI control.

Key Features

Feature	Design Value
Ultra-low R_DS(on) at 4.5 V	Enables direct interface with 3.3 V/5 V microcontrollers and PWM controllers without level-shifting circuitry.
Fully characterized avalanche rating	Guarantees reliable operation under transient overcurrent conditions in non-isolated buck converters.
Low Q_gd/Q_gs ratio	Reduces Miller plateau duration, improving immunity to dV/dt-induced false turn-on in high-side configurations.
Optimized body diode recovery	Minimizes reverse recovery tail current, lowering switching losses and snubber requirements in synchronous rectification.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level Power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRLR3715PBF	20 V, 32 A, R_DS(on) = 22 mΩ @ 4.5 V; higher Q_g (11.5 nC)	Lower current rating and slower switching limit use in >25 A VRMs	Select when lower cost is prioritized over peak efficiency at high load.
SI2302DS-T1-E3	20 V, 2.6 A, R_DS(on) = 75 mΩ @ 4.5 V; SOT-23 package	Not suitable for >5 A loads; lacks avalanche rating and thermal mass	Only appropriate for low-power auxiliary rails or bias supplies.

Compared with IRLR3714TRLPBF, the IRLR3715PBF trades marginal R_DS(on) increase for broader availability, while the SI2302DS-T1-E3 serves entirely different power-class applications-neither offers drop-in replacement capability for high-current synchronous rectification.

FAQ

Is IRLR3714TRLPBF suitable for 3.3 V gate drive?

No. While rated for 4.5 V logic-level operation, its V_GS(th) minimum is 1.0 V and typical turn-on occurs above 2.5 V, but R_DS(on) rises sharply below 4.5 V. At 3.3 V, R_DS(on) exceeds 45 mΩ-doubling conduction loss. Use only with ≥4.5 V gate drivers.

What is the maximum recommended PCB copper area for thermal relief?

For optimal R_θJC = 3.2 °C/W, the D-Pak drain pad must connect to ≥250 mm² of 2 oz copper on inner layer(s), with ≥4 thermal vias (0.3 mm diameter) directly under the pad. Smaller areas increase junction temperature by >15 °C at 30 A continuous.

Does IRLR3714TRLPBF have lead-free and RoHS-compliant construction?

Yes. The "PbF" suffix confirms lead-free termination and full compliance with EU RoHS Directive 2011/65/EU and JEDEC J-STD-609A Class 3 moisture sensitivity. MSL rating is Level 1 (unlimited floor life at ≤30°C/60% RH).

Can it replace IRLR3714PbF in existing designs?

Yes. IRLR3714TRLPBF is the tape-and-reel packaging variant of IRLR3714PbF, sharing identical die, parametric specs, and qualification. Only packaging differs: TRLPBF denotes 3,000-piece reel with embossed carrier tape; PbF denotes bulk or tube packaging.
