Product details

Overview

IRFL014PBF from Vishay Siliconix is a 60 V, 2.7 A N-channel enhancement-mode power MOSFET in SOT-223 package, featuring 0.20 Ω R_DS(on) at V_GS = 10 V, 11 nC total gate charge, and 100 mJ single-pulse avalanche energy - optimized for low-power DC-DC converters, LED drivers, and load-switching applications.

For engineers reviewing the IRFL014PBF datasheet, IRFL014PBF pinout, IRFL014PBF application, or IRFL014PBF equivalent, key selection criteria include its surface-mount SOT-223 thermal performance (2.0 W PCB-mount power dissipation), fast switching (10 ns turn-on delay, 19 ns fall time), dynamic dV/dt rating (4.5 V/ns), and ease of paralleling due to positive temperature coefficient of R_DS(on).

Technical Context

This MOSFET employs planar V-groove technology for ruggedized unclamped inductive switching, with built-in body diode characterized for 70–140 ns reverse recovery time and 0.20–0.40 μC Q_rr. Its gate threshold voltage (2.0–4.0 V) supports standard logic-level drive without level-shifting.

The device operates across –55 °C to +150 °C junction temperature range and is rated for 60 V drain-source breakdown with ±20 V gate-source voltage tolerance. Thermal resistance is 60 °C/W (junction-to-ambient, PCB mount) and 40 °C/W (junction-to-case), enabling reliable operation under moderate heatsinking.

Key Specifications

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
SiHFL014TR-GE3	Same die, Pb-free/halogen-free SOT-223 variant; identical R_DS(on), Q_g, and thermal specs	No functional difference; preferred for RoHS-compliant production	Select SiHFL014TR-GE3 when lead-free compliance is mandatory per IPC-J-STD-609
IRFL9110PBF	60 V, 1.8 A, 0.40 Ω R_DS(on), higher V_GS(th) (2.5–4.5 V); lower current rating and higher on-resistance	Less suitable for >2 A continuous loads; higher conduction loss at same current	Choose IRFL9110PBF only if lower gate charge (7.5 nC) or legacy design reuse outweighs efficiency penalty

Compared with IRFL014PBF, SiHFL014TR-GE3 offers identical electrical and thermal performance with updated environmental compliance, while IRFL9110PBF trades off conduction efficiency for marginally faster gate charging - making IRFL014PBF optimal for thermally constrained 2–2.7 A switching applications.

FAQ

What is the maximum continuous drain current rating for IRFL014PBF at 100 °C case temperature?

The IRFL014PBF is rated for 1.7 A continuous drain current at T_C = 100 °C, reflecting linear derating from 2.7 A at 25 °C using a factor of 0.025 W/°C. This value is validated under standard SOT-223 PCB-mount conditions per Vishay document 91191, and must be applied when ambient temperature or board layout limits heat dissipation.

Does IRFL014PBF have a built-in body diode, and what are its key parameters?

Yes, IRFL014PBF integrates a monolithic body diode with 2.7 A continuous forward current rating, 1.6 V forward voltage at 2.7 A and 25 °C, and 70–140 ns reverse recovery time. Its Q_rr is 0.20–0.40 μC, making IRFL014PBF suitable for synchronous rectification where controlled diode conduction and recovery are critical.

Can IRFL014PBF be driven directly by a 3.3 V microcontroller GPIO pin?

No - IRFL014PBF has a gate threshold voltage range of 2.0–4.0 V and requires ≥10 V V_GS to achieve its specified 0.20 Ω R_DS(on). At 3.3 V, R_DS(on) rises significantly (>1.5 Ω), increasing conduction loss. A gate driver or level shifter is required for full enhancement; IRFL014PBF is not a logic-level MOSFET.

What is the avalanche energy rating of IRFL014PBF, and under what test conditions is it specified?

The IRFL014PBF is rated for 100 mJ single-pulse avalanche energy (E_AS) under conditions of V_DD = 25 V, starting T_J = 25 °C, L = 16 mH, R_g = 25 Ω, and I_AS = 2.7 A. This rating validates robustness against inductive switching transients without external clamping, as confirmed in Figure 12 of Vishay document 91191.

Is IRFL014PBF suitable for use in automotive applications?

IRFL014PBF is not AEC-Q101 qualified and is intended for industrial, consumer, and commercial applications. While it operates across –55 °C to +150 °C, its qualification data, failure-in-time (FIT) rates, and stress-test coverage do not meet automotive-grade requirements. For automotive use, designers should select Vishay's AEC-Q101-qualified equivalents such as SQJAxx series instead of IRFL014PBF.
