Product details

Overview

IRF8714PBF from Infineon Technologies (formerly International Rectifier) is a 30V, 14A N-channel enhancement-mode HEXFET Power MOSFET in SO-8 package, optimized for synchronous buck converter topologies with R_DS(on) = 7.1 mΩ @ V_GS = 10V, Q_g = 8.1 nC, and ultra-low gate impedance of 1.6 Ω. It serves as the control MOSFET in notebook CPU power delivery and isolated DC-DC converters for networking equipment.

For engineers reviewing the IRF8714PBF datasheet, IRF8714PBF pinout, IRF8714PBF application, or IRF8714PBF equivalent, key selection criteria include its 4.5V-rated R_DS(on) performance, fully characterized avalanche capability (E_AS = 65 mJ), and SO-8 thermal resistance (R_θJA = 50–55 °C/W), critical for high-efficiency, space-constrained DC-DC designs.

Technical Context

This MOSFET employs trench-gated HEXFET silicon technology to minimize conduction and switching losses simultaneously-achieved via low R_DS(on) (7.1 mΩ typ. @ 10V) and low total gate charge (8.1 nC). Its gate threshold voltage (1.35–2.35 V) enables robust 4.5V drive compatibility in modern controller ICs.

The device integrates a fast, low-V_SD body diode (V_SD ≤ 1.0 V @ I_S = 11A) with t_rr = 14–21 ns and Q_rr = 15–23 nC, supporting efficient synchronous rectification and unclamped inductive switching. Fully tested R_g (1.6–2.6 Ω) ensures predictable turn-on/turn-off timing (t_d(on) = 10 ns, t_f = 5.0 ns).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS Rating	30 V - supports input rails up to 24 V in buck converters with margin against transients
R_DS(on) @ 10V	7.1 mΩ max - reduces conduction loss to <1 W at 14 A continuous drain current
Q_g	8.1 nC - enables fast, low-loss switching with standard gate drivers at >1 MHz frequencies
V_GS(th)	1.35–2.35 V - ensures reliable turn-on with 3.3V/4.5V logic-level controllers
R_g	1.6–2.6 Ω - provides consistent, predictable switching edge rates without external gate resistors
E_AS	65 mJ - withstands unclamped inductive energy in hot-swap and load-dump conditions
t_rr	14–21 ns - minimizes body-diode reverse recovery loss during synchronous FET commutation

Pinout & Package

IRF8714PBF is housed in a standard SO-8 surface-mount package with exposed drain pad for enhanced thermal performance. Pin 1 is Gate (G), Pins 2–4 and 6–8 are Drain (D), Pin 5 is Source (S), and Pin 7 is Source (S) - dual-source configuration improves current sharing and reduces source inductance in high-di/dt applications.

Pin/Terminal	Circuit Role	Design Meaning
1	Gate	Control terminal; low input capacitance (C_iss = 1020 pF) enables fast, low-power driving
2,3,4,6,8	Drain	Main power path; multiple pins reduce resistance and inductance in high-current paths
5,7	Source	Return path for channel current; dual-source layout lowers common-source inductance and improves stability

Key Features

Feature	Design Value
Ultra-low R_DS(on) at 4.5V	8.7 mΩ max - enables direct drive from 4.5V PWM controllers without level-shifting
Very low gate charge	Q_g = 8.1 nC - cuts switching loss by >30% vs. legacy SO-8 MOSFETs at 500 kHz
Fully characterized avalanche	E_AS = 65 mJ @ I_AS = 11 A - eliminates need for external snubbers in inductive switching
Lead-free and RoHS-compliant	Pb-free plating per JEDEC J-STD-020 - supports automated reflow and long-term reliability

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
IRL8726PBF	R_DS(on) = 6.0 mΩ @ 4.5V (lower), Q_g = 12.5 nC (higher), same SO-8 package	Better 4.5V drive but slower switching; suited for lower-frequency, higher-current apps	Prefer when gate drive voltage is limited to 4.5V and switching frequency <300 kHz
SiR872DP	R_DS(on) = 5.8 mΩ @ 4.5V, Q_g = 10.5 nC, TrenchFET Gen IV, same pinout	Lower R_DS(on) and higher Q_g; slightly higher cost but improved thermal resistance	Choose for highest efficiency at 12 V input with tight thermal constraints

Compared with IRL8726PBF and SiR872DP, IRF8714PBF offers the best balance of low Q_g and mid-range R_DS(on), making it optimal for 300–600 kHz synchronous buck converters where both switching and conduction losses must be minimized.

FAQ

What is the maximum continuous drain current for IRF8714PBF at 70°C ambient?

The maximum continuous drain current is 11 A at T_A = 70°C with PCB-mounted SO-8 layout per datasheet Fig. 9. This rating assumes 1 in² copper area (2 oz) and accounts for R_θJA derating. At T_A = 25°C, it rises to 14 A due to reduced thermal resistance.

Does IRF8714PBF support 4.5V gate drive in synchronous buck applications?

Yes. Its R_DS(on) is specified at 8.7 mΩ max @ V_GS = 4.5V, and V_GS(th) range (1.35–2.35 V) ensures full enhancement with 4.5V logic-level drivers. The low Q_g (8.1 nC) further guarantees fast, low-loss switching under this condition.

How is avalanche ruggedness validated for IRF8714PBF?

IRF8714PBF is 100% tested for single-pulse avalanche energy (E_AS) up to 65 mJ at I_AS = 11 A, per Fig. 13. Test conditions follow JEDEC JESD24-11 using unclamped inductive switching (UIS) with di/dt = 300 A/µs and V_DD = 15 V, ensuring robustness in real-world overvoltage events.

Can IRF8714PBF replace older SO-8 MOSFETs like IRF7807 in existing designs?

Yes, with verification. IRF8714PBF shares identical SO-8 footprint and pinout (G-D-D-D-S-A-S-A), but offers 25% lower R_DS(on) and 30% lower Q_g. Layout changes are unnecessary, though gate drive strength and thermal margin should be rechecked due to higher peak currents enabled by improved performance.
