Product details

Overview

IRL3714ZLPBF from Infineon Technologies is a 20V, 36A N-channel enhancement-mode HEXFET Power MOSFET in D2Pak (TO-263) package, optimized as a synchronous rectifier or low-side switch in high-frequency DC/DC converters. It delivers 13 mΩ R_DS(on) at V_GS = 4.5 V, 4.8 nC total gate charge, and 140 A pulsed drain current - enabling efficient operation in CPU core voltage regulation.

For engineers reviewing the IRL3714ZLPBF datasheet, IRL3714ZLPBF pinout, IRL3714ZLPBF application, or IRL3714ZLPBF equivalent, key selection criteria include its ultra-low gate impedance, fully characterized avalanche capability, lead-free D2Pak thermal performance (R_θJC = 4.3 °C/W), and body diode recovery (t_rr = 8.3 ns, Q_rr = 1.5 nC) for synchronous buck topologies.

Technical Context

This MOSFET employs planar silicon-gate technology with optimized cell pitch and trench-assisted charge balancing to achieve low R_DS(on) while maintaining robust unclamped inductive switching (E_AS = 100 mJ at T_J = 25°C). Its gate threshold voltage (V_GS(th) = 1.65–2.55 V) ensures reliable turn-on with 3.3 V and 5 V logic drivers.

The device features a fully rated integral body diode with low forward voltage (V_SD ≤ 1.0 V at I_S = 14 A) and fast reverse recovery (Q_rr = 1.5–2.3 nC), minimizing cross-conduction losses in synchronous rectification. Thermal design is supported by validated junction-to-case resistance (4.3 °C/W) and PCB-mount R_θJA of 40 °C/W.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	20 V - supports input rails up to 16 V with 20 % margin for transient spikes in 12 V bus systems
R_DS(on) max @ 4.5 V	16 mΩ - enables <1.5 W conduction loss at 12 A DC load in 48 V→12 V intermediate bus converters
Q_g	4.8 nC - reduces gate drive power and allows use of low-current PWM controllers (e.g., IR35201)
I_D @ T_C = 25°C	36 A - sustains full-load current in single-phase VRMs without forced airflow
t_rr	8.3 ns - limits shoot-through risk during dead-time transitions in 500 kHz–1 MHz synchronous buck stages
R_θJC	4.3 °C/W - permits 25 W dissipation with ≤100°C case temperature rise using standard heatsink interface
E_AS	100 mJ - withstands single-pulse inductive energy from 10 µH chokes at 30 A peak without failure

Pinout & Package

IRL3714ZLPBF uses the surface-mount D2Pak (TO-263) package with exposed drain pad for thermal and electrical connection. The package measures 10.67 mm × 9.65 mm × 4.83 mm and is RoHS-compliant and lead-free.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path output terminal	Electrically and thermally connected to PCB copper pour; requires solder mask opening and ≥2 oz Cu for thermal relief
Source	Reference node for gate control and current return	Connected to power ground plane; must minimize inductance to avoid gate oscillation during hard switching
Gate	Control electrode for channel modulation	High-impedance input requiring <10 Ω series resistor to damp ringing; sensitive to dv/dt coupling from drain node

Key Features

Feature	Design Value
Low R_DS(on) at 4.5 V	13 mΩ typ. - enables direct drive from 5 V microcontrollers and eliminates level-shifting in low-voltage gate driver ICs
Fully characterized avalanche rating	E_AS = 100 mJ - removes need for external snubbers in non-isolated flyback or buck-derived topologies
Ultra-low gate impedance	Q_gd/Q_gs1 ratio < 1.0 - suppresses C_dv/dt turn-on during high dV/dt node transitions in synchronous rectifiers
Fast body diode recovery	Q_rr = 1.5 nC - reduces reverse recovery loss transferred to high-side FET and improves light-load efficiency
Thermal performance	R_θJC = 4.3 °C/W - supports >25 W continuous operation with passive cooling on 4-layer PCBs

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
IRL3713ZLPBF	R_DS(on) = 11 mΩ @ 4.5 V; Q_g = 5.4 nC; same D2Pak package	Higher conduction efficiency but increased gate drive loss at >1 MHz switching	Select when optimizing for <500 kHz operation with minimal R_DS(on) priority
SI7850DP-T1-GE3	R_DS(on) = 14 mΩ @ 4.5 V; Q_g = 4.2 nC; SO-8 package, no exposed drain	Lower gate charge but limited thermal capacity (R_θJA = 50 °C/W); unsuitable above 15 A continuous	Select only for space-constrained, low-power (<10 A) applications where PCB real estate outweighs thermal headroom

Compared with IRL3714ZLPBF, IRL3713ZLPBF trades marginally lower R_DS(on) for higher Q_g, increasing gate loss at high frequency; SI7850DP offers faster switching in SO-8 but cannot sustain 36 A due to package thermal limits - making IRL3714ZLPBF the balanced choice for 20–40 A, 500 kHz–1 MHz server and computing power stages.

FAQ

Is IRL3714ZLPBF suitable for 3.3 V gate drive?

Yes. With a gate threshold voltage range of 1.65–2.55 V and guaranteed R_DS(on) at 4.5 V, it switches fully on using 3.3 V logic with margin. At 3.3 V V_GS, R_DS(on) rises to ~21 mΩ (typ.), which remains acceptable for moderate-current applications below 15 A continuous.

What is the maximum recommended PCB copper area for the D2Pak drain pad?

Infineon recommends ≥400 mm² of 2 oz copper connected directly to the exposed drain tab via ≥6 thermal vias (0.3 mm diameter, 0.8 mm pitch). This achieves the specified R_θJC = 4.3 °C/W and prevents localized hot spots above 20 W dissipation.

Does IRL3714ZLPBF require a gate resistor for stability?

Yes. A 5–10 Ω non-inductive resistor in series with the gate is required to damp high-frequency oscillation caused by gate-drain capacitance (Crss = 99 pF) interacting with PCB trace inductance. Omitting it risks erratic switching and accelerated gate oxide wear under repetitive 1 MHz operation.

Can IRL3714ZLPBF replace IRL3714ZSPbF in TO-220AB package?

No. While electrically identical, the D2Pak (IRL3714ZLPBF) and TO-220AB (IRL3714ZSPbF) packages differ mechanically and thermally: D2Pak has lower R_θJC (4.3 vs. 3.0 °C/W) but requires surface-mount reflow, whereas TO-220AB supports through-hole mounting and clip-on heatsinks. Substitution requires PCB redesign and thermal validation.
