Product details
Overview
IRL3714ZPBF from Infineon Technologies is a 20V N-channel HEXFET Power MOSFET in TO-262 (I2PAK) package, optimized as a synchronous rectifier FET in high-frequency buck converters for CPU core power delivery. It delivers 16 mΩ RDS(on) at VGS = 4.5 V, 4.8 nC total gate charge, and 14 A continuous drain current at TC = 25°C, enabling efficient low-voltage, high-current switching in server and desktop VRMs.
For engineers reviewing the IRL3714ZPBF datasheet, IRL3714ZPBF pinout, IRL3714ZPBF application in synchronous buck stages, or IRL3714ZPBF equivalent for 20V logic-level MOSFETs, this page provides verified electrical parameters, thermal performance data, validated pin configuration, and direct-fit alternatives for VRM design continuity and supply chain resilience.
Technical Context
This MOSFET employs planar vertical HEXFET architecture with fully characterized unclamped inductive avalanche capability (EAS = 100 mJ at TJ = 25°C) and ultra-low gate impedance to support fast switching at >1 MHz frequencies. Its 99 pF Crss and 2.5 nC Qsw minimize Miller-induced turn-on risk in high-dV/dt node environments.
The device features a robust body diode with 8.3–12 ns reverse recovery time (trr) and 1.5–2.3 nC Qrr, enabling reliable synchronous rectification without external Schottky supplementation. Its RθJC = 4.3°C/W supports direct heatsink mounting in compact VRM layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 20 V - Maximum blocking voltage compatible with 12 V input rails and transient overshoot margins in modern CPU VRMs. |
| RDS(on) max @ 4.5 V | 16 mΩ - Enables <1.5 W conduction loss at 12 A DC load, critical for thermally constrained socket-mounted VRMs. |
| Qg | 4.8 nC - Low gate drive energy reduces controller gate driver stress and enables use with low-power PWM ICs like IR35201. |
| ID @ TC = 25°C | 36 A - Supports peak phase current demands in multi-phase 150 W+ CPU power stages without derating. |
| RθJC | 4.3 °C/W - Allows direct thermal interface to heatsink; junction-to-case path sustains 140 W dissipation before reaching 175°C TJ. |
| trr | 8.3–12 ns - Fast body diode recovery prevents shoot-through during dead-time transitions in synchronous buck operation. |
| VGS(th) | 1.65–2.55 V - Guaranteed turn-on with 3.3 V logic-level gate drivers, eliminating need for level-shifting in integrated PMIC designs. |
Pinout & Package
IRL3714ZPBF uses the TO-262 (I2PAK) package: 3-pin, single-ended, isolated tab, surface-mount compatible with through-hole footprint adaptation. Tab is electrically connected to the Drain terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path from source to load | Electrically tied to metal tab; requires insulated mounting or heatsink isolation; carries full output current in synchronous FET position. |
| Source | Reference node for gate control and current return | Connected to power ground plane; serves as common reference for gate drive and current sensing in low-side configuration. |
| Gate | Control electrode for channel modulation | High-impedance input requiring <5 V logic-level drive; sensitive to dV/dt coupling-layout must minimize loop area with gate resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) at 4.5 V | 16 mΩ enables <1 W conduction loss at 12 A, reducing thermal load on PCB and allowing tighter phase spacing in multi-phase VRMs. |
| Fully characterized avalanche rating | EAS = 100 mJ ensures survivability during transient overloads and inductor saturation events without derating or external clamping. |
| Low Qgd/Qgs1 ratio | Qgd = 1.7 nC, Qgs1 = 1.7 nC minimizes Cdv/dt turn-on risk at switching nodes with >10 V/ns slew rates typical in 500 kHz–1 MHz VRMs. |
| Lead-free D2Pak-compatible footprint | TO-262 package maintains mechanical and thermal compatibility with legacy D2Pak layouts while meeting RoHS/REACH requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 20V logic-level power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRL3713ZPBF | RDS(on) = 12 mΩ @ 4.5 V; Qg = 5.7 nC; TO-262 package | Lower conduction loss but higher gate charge increases switching loss above 600 kHz | Preferred for <600 kHz VRMs where conduction dominates; less suitable for 1 MHz+ high-density designs. |
| SI7850DP-T1-GE3 | RDS(on) = 14 mΩ @ 4.5 V; Qg = 4.2 nC; PowerPAK SO-8 package | Smaller footprint and lower Qg, but RθJA = 40°C/W limits power handling without copper pour | Better for space-constrained consumer boards; not recommended for >40 A continuous industrial loads due to thermal limitations. |
Compared with IRL3714ZPBF, IRL3713ZPBF trades higher gate drive loss for lower conduction loss, while SI7850DP-T1-GE3 offers superior switching efficiency in compact layouts but lacks the thermal headroom for high-current server applications.

FAQ
Is IRL3714ZPBF RoHS-compliant and lead-free?
Yes, IRL3714ZPBF is lead-free and RoHS-compliant per EU Directive 2011/65/EU. The "PbF" suffix explicitly denotes lead-free plating and packaging. It meets JEDEC J-STD-020 moisture sensitivity level 1 and is qualified for reflow soldering up to 260°C for 10 seconds.
What is the maximum safe operating frequency for IRL3714ZPBF in a synchronous buck converter?
IRL3714ZPBF supports stable operation up to 1.2 MHz based on its 2.5 nC Qsw, 99 pF Crss, and 13 ns rise time. Above 1 MHz, layout parasitics dominate; optimal performance is achieved between 500 kHz and 1 MHz with gate resistance ≤2.2 Ω and minimized source inductance.
Does IRL3714ZPBF require a gate resistor, and what value is recommended?
Yes-a gate resistor is required to dampen ringing and control dV/dt. For 500–800 kHz operation, a 2.2 Ω non-inductive resistor between driver output and gate is recommended. At 1 MHz+, reduce to 1.5 Ω; values below 1 Ω increase risk of oscillation without compromising switching speed.
Can IRL3714ZPBF be used as a high-side switch in a floating-gate configuration?
No-it is optimized as a low-side or synchronous rectifier FET. Its 20 V VDS rating and lack of integrated bootstrap diode or level-shifter make it unsuitable for high-side operation in buck topologies. Use dedicated high-side drivers (e.g., IR2110) with 30 V+ rated MOSFETs for that role.
