Product details

Overview

IRFR014 from Vishay Siliconix is a 60 V, 7.7 A N-channel surface-mount power MOSFET in DPAK (TO-252) package, featuring 0.20 Ω R_DS(on) at V_GS = 10 V, 11 nC total gate charge, and 27.4 mJ single-pulse avalanche energy - designed for DC-DC converters, motor drivers, and load switching in industrial power supplies.

For engineers reviewing the IRFR014 datasheet, IRFR014 pinout, IRFR014 application, or IRFR014 equivalent, key selection criteria include its 60 V V_DS, 0.20 Ω on-resistance at 10 V drive, 11 nC Q_g, 5.0 °C/W R_thJC, and DPAK thermal performance under PCB-mounted conditions.

Technical Context

This third-generation TrenchFET® MOSFET uses optimized silicon geometry to achieve low conduction loss while maintaining rugged unclamped inductive switching capability. Its 27.4 mJ E_AS rating and 4.5 V/ns peak diode recovery dV/dt support reliable operation in hard-switched topologies without external snubbers.

The device integrates a fast-recovery body diode with t_rr = 70–140 ns and Q_rr = 0.20–0.40 μC, enabling efficient synchronous rectification and freewheeling in buck and half-bridge circuits. Gate drive is simplified by a 2.0–4.0 V V_GS(th) and low 3.1 nC Q_gs, supporting direct microcontroller interfacing.

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
SiHFR014-GE3	Same die, identical R_DS(on), Q_g, and E_AS; Pb-free and halogen-free construction	No functional difference; preferred for RoHS-compliant production	Select SiHFR014-GE3 when lead-free/halogen-free compliance is required per IPC-J-STD-609
IRFU014PbF	Identical electrical specs but IPAK (TO-251) through-hole package; higher R_thJA (110 °C/W vs. 50 °C/W PCB mount)	Suitable for prototyping or low-volume through-hole assembly; not drop-in compatible with DPAK footprint	Choose IRFU014PbF only when board layout mandates through-hole mounting and thermal derating is acceptable

Compared with IRFR014, SiHFR014-GE3 offers identical performance with environmental compliance, while IRFU014PbF trades surface-mount thermal efficiency for through-hole mechanical robustness - neither is pin-compatible, requiring layout revision.

FAQ

What is the maximum continuous drain current for IRFR014 at 100 °C case temperature?

The IRFR014 supports 4.9 A continuous drain current at T_C = 100 °C, derived from its 25 W P_D rating and 0.20 W/°C linear derating factor. This value assumes proper thermal coupling to a heatsink or thermally enhanced PCB - actual current must be validated against measured junction temperature using R_thJC = 5.0 °C/W.

Does IRFR014 have a logic-level gate drive requirement?

The IRFR014 is not a logic-level MOSFET; its gate threshold voltage ranges from 2.0 V to 4.0 V, and it is specified for R_DS(on) at V_GS = 10 V. While it can turn on with 5 V drive, full enhancement requires ≥10 V to achieve the rated 0.20 Ω on-resistance - use of 3.3 V logic directly is not recommended without gate boosting.

What is the avalanche energy rating of IRFR014 and how is it tested?

The IRFR014 has a single-pulse avalanche energy rating of 27.4 mJ, measured under conditions of V_DD = 25 V, starting T_J = 25 °C, L = 924 μH, R_g = 25 Ω, and I_AS = 7.7 A per Figure 12 of the datasheet. This rating validates ruggedness during unclamped inductive switching but does not imply unlimited repetitive avalanche capability.

Can IRFR014 be paralleled with other MOSFETs for higher current handling?

Yes, the IRFR014 is designed for ease of paralleling due to its positive temperature coefficient of R_DS(on), which promotes current sharing across multiple devices. Successful paralleling requires matched gate drive paths, symmetrical PCB layout, and individual gate resistors to suppress oscillation - refer to Vishay Application Note AN826 for layout guidelines.

What is the thermal resistance from junction to ambient for IRFR014 in a typical PCB mount configuration?

When mounted on a 1" square FR-4 PCB, the IRFR014 exhibits R_thJA = 50 °C/W. This value assumes standard JEDEC test conditions and defines the maximum power dissipation (2.5 W at T_A = 25 °C) before exceeding T_J(max) = 150 °C - actual performance depends on copper area, layer count, and airflow.
