Product details

Overview

IRLR014 from Vishay Siliconix is a 60 V, 7.7 A N-channel surface-mount power MOSFET in DPAK (TO-252) package, featuring logic-level gate drive (V_GS(th) = 1.0–2.0 V), R_DS(on) = 0.20 Ω at V_GS = 5 V, and fast switching with Q_g = 8.4 nC - used in DC-DC converters, motor control stages, and load switching circuits requiring low gate drive voltage and rugged unclamped avalanche capability.

For engineers reviewing the IRLR014 datasheet, IRLR014 pinout, IRLR014 application, or IRLR014 equivalent, key selection considerations include its 60 V V_DS, 0.20 Ω on-resistance at 5 V gate drive, 8.4 nC total gate charge, 27.4 mJ single-pulse avalanche energy, and thermal resistance of 5.0 °C/W junction-to-case - critical for high-reliability, space-constrained power stage designs.

Technical Context

The IRLR014 employs a third-generation TrenchFET® process optimized for low R_DS(on) and fast switching, with dynamic dV/dt rating up to 4.5 V/ns and integral body diode recovery time (t_rr) of 65–130 ns. Its gate threshold voltage range (1.0–2.0 V) ensures reliable turn-on with 3.3 V or 5 V logic controllers.

Designed for surface mounting on FR-4 PCBs, the DPAK package delivers 2.5 W power dissipation in PCB-mount configuration and supports vapor-phase, infrared, or wave soldering. The device's unclamped inductive switching capability (E_AS = 27.4 mJ) enables robust operation in flyback and motor drive topologies without external snubbers.

Pinout & Package

DPAK (TO-252) surface-mount package with exposed drain pad for thermal and electrical connection; 3-terminal configuration (G, D, S) with G and S on leads, D on bottom thermal pad.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control electrode	Accepts logic-level voltage (≥4 V) to fully enhance channel; requires <8.4 nC charge for full turn-on
D (Drain)	High-side current output	Connected to exposed thermal pad; carries full load current and serves as primary heat transfer path to PCB

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced with 4–5 V gate voltage - eliminates need for gate driver IC in 3.3 V/5 V MCU systems
Ruggedized dV/dt rating	4.5 V/ns immunity - prevents false turn-on during high-speed switching in noisy power environments

SiHLR014-GE3	Pb-free/halogen-free variant of same die and package; identical electrical specs and pinout	Required for RoHS-compliant and green manufacturing programs	Direct material substitution - no design or layout changes needed for compliance upgrade

Compared with IRLR2905Z, the IRLR014 offers lower gate charge (8.4 nC vs. 22 nC) and true logic-level operation but higher R_DS(on); compared with SiHLR014-GE3, it shares identical performance but differs only in lead finish and environmental compliance status.

FAQ

What is the maximum continuous drain current for IRLR014 at 100 °C case temperature?

The IRLR014 supports 4.9 A continuous drain current at T_C = 100 °C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limitations of the DPAK package under sustained high-temperature operation and must be validated against actual PCB layout and heatsinking. The IRLR014 datasheet confirms this value applies to surface-mount configurations with proper copper area per Application Note 826.

Does IRLR014 require a gate resistor for safe operation?

Yes - while not strictly mandatory, a gate resistor (typically 10–25 Ω) is recommended for the IRLR014 to control dI/dt, suppress ringing, and prevent parasitic oscillation during switching. The IRLR014 datasheet specifies R_g = 25 Ω in its switching time test conditions (Fig. 10b), and its 8.4 nC Q_g makes it sensitive to fast edge rates without damping. Omitting the resistor may cause shoot-through or EMI in high-frequency applications.

Can IRLR014 be used in avalanche mode repeatedly?

No - the IRLR014 is rated for single-pulse avalanche energy (E_AS = 27.4 mJ), not repetitive avalanche. Its datasheet explicitly states "repetitive rating; pulse width limited by maximum junction temperature" and defines E_AS under unclamped inductive switching with specific test conditions (V_DD = 25 V, I_AS = 7.7 A). Repeated avalanche stress exceeds design intent and risks parametric shift or failure; use clamping or snubbing for cyclic inductive loads.

What is the thermal resistance from junction to ambient for IRLR014 in standard PCB mount?

The IRLR014 has a maximum junction-to-ambient thermal resistance (R_thJA) of 50 °C/W when mounted on a 1" square FR-4 PCB, per its Thermal Resistance Ratings table. This value assumes optimal copper pour under the exposed drain pad and is significantly better than the 110 °C/W rating for still-air conditions. The IRLR014's 5.0 °C/W R_thJC confirms its suitability for heatsink attachment when higher power dissipation is required.

Is IRLR014 compatible with lead-free reflow soldering processes?

Yes - the IRLR014PbF and IRLR014TRLPbFa ordering variants are lead-free and qualified for standard Pb-free reflow profiles, including peak temperatures up to 260 °C for 10 seconds. The IRLR014 datasheet specifies "Soldering recommendations (peak temperature): 260 °C for 10 s", confirming compatibility with IPC/JEDEC J-STD-020-compliant processes. Always verify landing pad geometry per Vishay's Application Note 826 for DPAK thermal pad reliability.
