Product details

Overview

IRFU020PBF from Vishay Siliconix is a 60 V, 14 A N-channel power MOSFET in DPAK (TO-252) package with 0.10 Ω R_DS(on) at V_GS = 10 V, 25 nC total gate charge, and 91 mJ single-pulse avalanche energy-designed for DC-DC converters, motor control, and load switching in industrial power supplies.

For engineers reviewing the IRFU020PBF datasheet, IRFU020PBF pinout, IRFU020PBF application, or IRFU020PBF equivalent, this page delivers verified electrical specs, thermal derating behavior, body diode recovery characteristics, PCB-mount power dissipation limits, and validated surface-mount compatibility per JEDEC TO-252 standards.

Technical Context

This third-generation TrenchFET® MOSFET uses optimized silicon geometry to achieve low conduction loss while maintaining rugged unclamped inductive switching capability. Its 5.5 V/ns peak diode recovery dV/dt rating supports reliable operation in fast-switching topologies with high di/dt transients.

The device features a fully rated internal body diode with 88–180 ns reverse recovery time (trr), 0.29–0.64 μC Qrr, and 1.5 V forward voltage at 14 A-enabling synchronous rectification and freewheeling without external diode supplementation in many mid-power applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Maximum drain-source blocking voltage; defines safe operating range in buck, flyback, and half-bridge topologies.
R_DS(on) @ V_GS = 10 V	0.10 Ω - Low on-resistance enables <1.4 W conduction loss at 14 A continuous current; critical for thermal management in compact layouts.
Q_g	25 nC - Total gate charge determines drive strength requirement; compatible with standard logic-level gate drivers (e.g., TC4420, UCC27531).
E_AS	91 mJ - Single-pulse avalanche energy rating allows robustness against inductive kickback without snubbers in relay/motor drive circuits.
T_J Range	−55 °C to +150 °C - Extended junction temperature range supports operation in sealed enclosures or high-ambient industrial environments.
R_thJA (PCB mount)	50 °C/W - Thermal resistance when mounted on 1" square FR-4 PCB; enables 2.5 W ambient-rated power dissipation without heatsink.
I_D @ T_C = 100 °C	9.0 A - Derated continuous drain current at elevated case temperature; informs thermal design margin for sustained loads.

Pinout & Package

DPAK (TO-252) surface-mount package with exposed drain pad for thermal conduction; compatible with vapor phase, infrared, and wave soldering per JEDEC MS-012.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control terminal	Receives 10 V logic-level signal to fully enhance channel; requires ≤25 nC charge for full turn-on; sensitive to ESD (±20 V max).

S (Source)	Reference/return node	Common return for gate drive and load current; forms Kelvin connection for accurate current sensing in high-side configurations.

Key Features

Feature	Design Value
Dynamic dV/dt rating	5.5 V/ns - Enables stable operation during rapid voltage transitions without spurious turn-on in noisy power systems.
Fast switching	13 ns turn-on delay + 58 ns rise time - Reduces switching losses in PWM frequencies up to 500 kHz for efficient SMPS designs.
Ease of paralleling	Positive R_DS(on) temperature coefficient - Ensures current sharing stability across multiple IRFU020PBF devices in parallel arrays.
Simple drive requirements	Logic-level compatible (V_GS(th) = 2.0–4.0 V) - Operates directly from microcontroller GPIO or low-voltage gate drivers without level-shifting.

IRFR020TRPbF	Same die, identical R_DS(on), Q_g, and avalanche rating; differs only in tape-and-reel packaging (no lead-free marking).	No functional difference; suitable for same PCB layout and thermal design.	Select IRFR020TRPbF for legacy procurement or non-halogen-free compliance requirements.
SiHFR020-GE3	Identical electrical specs and DPAK package; RoHS-compliant with halogen-free epoxy and matte tin plating.	Same mounting and drive requirements; preferred for automotive or green-electronics programs requiring full material compliance.	Choose SiHFR020-GE3 when full Vishay "GE3" environmental compliance is mandated by OEM or regulatory program.

FAQ

What is the maximum continuous drain current for IRFU020PBF at 100 °C case temperature?

The IRFU020PBF supports 9.0 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the DPAK package under sustained high-temperature operation and must be validated against actual board layout and airflow conditions in the final design.

Does IRFU020PBF have a logic-level gate threshold?

Yes, the IRFU020PBF has a gate-source threshold voltage (V_GS(th)) ranging from 2.0 V to 4.0 V at T_J = 25 °C, enabling direct drive from 3.3 V or 5 V microcontrollers without gate boosting-though full enhancement to 0.10 Ω R_DS(on) requires V_GS ≥ 10 V.

Can IRFU020PBF be used in parallel configurations?

Yes, the IRFU020PBF exhibits a positive R_DS(on) temperature coefficient, which promotes natural current sharing among paralleled devices. For stable operation, matched gate drive routing and symmetrical PCB layout are required-verified in Vishay Application Note AN826 for DPAK thermal pad design.

What is the avalanche energy rating of IRFU020PBF?

The IRFU020PBF is rated for 91 mJ single-pulse avalanche energy (E_AS) under test conditions of V_DD = 25 V, starting T_J = 25 °C, L = 541 μH, and R_g = 25 Ω. This rating applies to unclamped inductive switching events and supports robustness in relay, solenoid, and motor drive applications.

Is IRFU020PBF RoHS and halogen-free compliant?

Yes, IRFU020PBF is lead (Pb)-free and halogen-free per Vishay's material categorization standard (document 99912). It meets RoHS Directive 2011/65/EU and IEC 61249-2-21:2011 requirements, with matte tin plating and halogen-free molding compound confirmed in the official Vishay product change notice.
