Product details

Overview

IRF710PBF-BE3 from Vishay Siliconix is a 400 V, 2.0 A N-channel power MOSFET in TO-220AB package, featuring 3.6 Ω R_DS(on) at V_GS = 10 V, 17 nC total gate charge, and repetitive avalanche rating-designed for flyback and SMPS primary-side switching in industrial AC-DC adapters.

For engineers reviewing the IRF710PBF-BE3 datasheet, IRF710PBF-BE3 pinout, IRF710PBF-BE3 application, or IRF710PBF-BE3 equivalent, key selection criteria include unclamped inductive switching capability (120 mJ E_AS), dV/dt ruggedness (4.0 V/ns), body diode recovery performance (240–540 ns t_rr), and thermal resistance (R_thJC = 3.5 °C/W).

Technical Context

This device belongs to Vishay's third-generation high-voltage power MOSFET family optimized for hard-switched topologies. Its design emphasizes dynamic ruggedness-evidenced by specified repetitive avalanche current (2.0 A I_AR) and energy (3.6 mJ E_AR)-and fast, controlled switching via low Q_gd/Q_g ratio (8.5/17 nC) and 21 ns turn-off delay.

The TO-220AB package enables direct heatsink mounting with 0.50 °C/W case-to-sink thermal resistance, while its 400 V V_DS rating and 2.0 A continuous drain current support operation in universal-input offline converters up to ~35 W output power under convection cooling.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	400 V - Supports 375 V DC link in universal AC input (85–265 VAC) flyback converters without derating.
R_DS(on)	3.6 Ω @ V_GS = 10 V - Limits conduction loss to ≤0.86 W at 1.2 A continuous ID, enabling thermally stable operation at TC = 100 °C.
Q_g	17 nC - Enables efficient gate drive with standard 10 V logic-level drivers; Q_gd/Q_g = 50% supports clean voltage-controlled switching transitions.
E_AS	120 mJ - Allows safe single-pulse unclamped inductive switching in transformer-coupled topologies without external snubbers.
t_r/t_f	9.9 ns / 11 ns - Reduces switching transition time, minimizing overlap loss in 65–100 kHz SMPS designs.
V_SD	1.6 V @ I_S = 2.0 A - Defines forward drop of integral body diode during synchronous rectification or freewheeling phases.

Pinout & Package

IRF710PBF-BE3 uses the industry-standard TO-220AB package with isolated tab (drain-connected), offering mechanical robustness, low thermal resistance (R_thJC = 3.5 °C/W), and compatibility with automated through-hole assembly.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control electrode	Receives 10 V gate drive signal; requires ≤11.2 Ω series resistance to damp ringing per internal R_g spec.
D (Drain)	High-side power terminal	Connected to TO-220AB metal tab; electrically tied to drain-must be insulated from heatsink unless referenced to same potential.
S (Source)	Power return and reference node	Serves as local ground reference for gate drive; source inductance (L_S = 7.5 nH) impacts switching waveform fidelity.

Key Features

Feature	Design Value
Repetitive avalanche rated	Supports reliable operation under transient overvoltage conditions (e.g., transformer leakage spikes) with 2.0 A I_AR and 3.6 mJ E_AR.
Dynamic dV/dt rating	4.0 V/ns immunity prevents false turn-on during high-speed voltage transients across drain-source terminals.
Fast switching	Combined 21 ns t_d(off) + 11 ns t_f enables high-frequency operation with minimized switching losses in 65–130 kHz converters.
Low Q_gd/Q_g ratio	8.5/17 = 0.5 reduces Miller plateau duration, improving controllability during hard-switching transitions.

FAQ

What is the maximum continuous drain current rating for IRF710PBF-BE3 at 100 °C case temperature?

The IRF710PBF-BE3 has a maximum continuous drain current (I_D) of 1.2 A when the case temperature (T_C) is 100 °C. This derating reflects thermal limitations of the TO-220AB package and ensures junction temperature remains within the -55 to +150 °C operating range. At T_C = 25 °C, the rating increases to 2.0 A. The linear derating factor is 0.29 W/°C for power dissipation.

Does IRF710PBF-BE3 have a specified avalanche energy rating?

Yes, IRF710PBF-BE3 is repetitively avalanche rated with a single-pulse avalanche energy (E_AS) of 120 mJ and repetitive avalanche energy (E_AR) of 3.6 mJ. These values are measured under defined test conditions (V_DD = 50 V, L = 52 mH, I_AS = 2.0 A) and confirm the device's ability to safely absorb inductive switching energy without failure-critical for flyback and forward converter reliability.

What is the gate threshold voltage range for IRF710PBF-BE3?

The gate-source threshold voltage (V_GS(th)) for IRF710PBF-BE3 is specified from 2.0 V to 4.0 V at V_DS = V_GS and I_D = 250 μA. This range indicates the minimum gate voltage required to begin channel conduction. Full enhancement and low R_DS(on) require V_GS ≥ 10 V, as confirmed by the 3.6 Ω on-resistance specification at that drive level.

Is IRF710PBF-BE3 compatible with standard TO-220AB footprints and heatsinks?

Yes, IRF710PBF-BE3 uses the standard TO-220AB package with drain-connected metal tab, matching mechanical dimensions and mounting hole pattern of industry-standard TO-220AB components. Its case-to-sink thermal resistance is 0.50 °C/W with greased surface contact, enabling direct attachment to heatsinks without insulating hardware-provided the heatsink is referenced to drain potential.

What is the typical reverse recovery time of the body diode in IRF710PBF-BE3?

The body diode reverse recovery time (t_rr) for IRF710PBF-BE3 is specified from 240 ns to 540 ns at T_J = 25 °C, I_F = 2.0 A, and dI/dt = 100 A/μs. This parameter directly affects switching loss and EMI in topologies where the body diode conducts, such as in asynchronous flyback or half-bridge configurations-designers should account for this in snubber and layout decisions.
