Product details

Overview

IRLL014 from Vishay Siliconix is a logic-level N-channel power MOSFET in SOT-223 package, rated for 60 V V_DS, 2.7 A continuous drain current at T_C = 25 °C, and R_DS(on) = 0.20 Ω at V_GS = 5 V. It features fast switching (t_r = 110 ns), low gate charge (Q_g = 8.4 nC), and dynamic dV/dt rating of 4.5 V/ns - used in DC-DC converter synchronous rectification and low-voltage motor control.

For engineers reviewing the IRLL014 datasheet, IRLL014 pinout, IRLL014 application, or IRLL014 equivalent, this page delivers verified electrical parameters, thermal performance data, SOT-223 terminal mapping, and real-world use cases for logic-driven high-side/low-side switching in space-constrained PCB designs.

Technical Context

This device belongs to Vishay's third-generation surface-mount power MOSFET family optimized for logic-level gate drive compatibility with 3.3 V and 5 V microcontrollers. Its R_DS(on) is specified at both V_GS = 4 V (0.28 Ω) and 5 V (0.20 Ω), enabling reliable turn-on under marginal gate drive conditions.

The SOT-223 package integrates an enlarged drain tab for enhanced thermal conduction, supporting >1.25 W power dissipation on FR-4 PCBs. Internal source/drain inductances (L_S = 6.0 nH, L_D = 4.0 nH) and body diode recovery characteristics (t_rr = 65–130 ns, Q_rr = 0.33–0.65 μC) are characterized for hard-switching and unclamped inductive load applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - supports 48 V rail systems with 20 % margin against transients
R_DS(on) @ V_GS = 5 V	0.20 Ω - enables <1.3 W conduction loss at 2.5 A DC load

E_AS	100 mJ - withstands single-pulse inductive energy up to 2.7 A × 25 V × 1.5 ms
T_J range	–55 to +150 °C - qualified for industrial ambient environments

Pinout & Package

SOT-223 package with exposed drain tab (pin 2) for thermal and electrical connection; standard 3-pin configuration with G-S-D layout. Mounting uses vapor-phase, infrared, or wave soldering per JEDEC TO-261AA outline.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (G)	Gate	Logic-level input requiring ≤2.0 V threshold; driven directly by MCU GPIO or low-power gate driver

Pin 3 (S)	Source	Reference node for gate drive; connects to ground or low-side return path in half-bridge configurations

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS = 4 V - eliminates need for level-shifting in 3.3 V control systems
Dynamic dV/dt rating	4.5 V/ns - prevents false turn-on during high-slew-rate voltage transients in noisy environments
Fast switching	110 ns rise time with 12 Ω gate resistor - reduces overlap loss in synchronous buck converters
Thermal-enhanced SOT-223	60 °C/W R_thJA (PCB mount) - achieves 2.0 W power dissipation on 1" FR-4 without heatsink
Body diode recovery	Q_rr = 0.33–0.65 μC - minimizes reverse-recovery loss when used as freewheeling diode in flyback or buck topologies

Compared with SiHLL014TR-GE3, IRLL014 offers identical performance with alternate manufacturing sourcing; versus DMN2004LK-7, IRLL014 provides 3× higher voltage rating and superior thermal handling in SOT-223, making it suitable for industrial 24–48 V power rails where reliability under transient overvoltage is essential.

FAQ

What is the maximum continuous drain current for IRLL014 at 100 °C case temperature?

The IRLL014 supports 1.7 A continuous drain current at T_C = 100 °C, per its Absolute Maximum Ratings table. This derating reflects thermal limitations of the SOT-223 package on standard PCBs; actual usable current depends on copper area, airflow, and ambient temperature. The IRLL014 maintains R_DS(on) stability up to 150 °C junction temperature.

Can IRLL014 be used with a 3.3 V microcontroller GPIO without a gate driver?

Yes - the IRLL014 has a gate threshold voltage (V_GS(th)) of 1.0–2.0 V and is fully enhanced at V_GS = 4 V, making it compatible with 3.3 V logic outputs. At 3.3 V, R_DS(on) increases slightly (to ~0.32 Ω estimated), but remains sufficient for ≤1.5 A loads. The IRLL014 avoids shoot-through risk in half-bridge use due to its moderate Q_g and dV/dt immunity.

What is the avalanche energy rating of IRLL014 and how is it tested?

The IRLL014 is rated for 100 mJ single-pulse avalanche energy (E_AS) under test conditions of V_DD = 25 V, starting T_J = 25 °C, L = 16 mH, and R_g = 25 Ω. This rating validates robustness against inductive switching transients in relay drivers or solenoid controls. The IRLL014 also specifies 0.31 mJ repetitive avalanche energy, confirming suitability for cyclic inductive loads.

How does the SOT-223 package of IRLL014 improve thermal performance over SOT-23?

The IRLL014's SOT-223 package features an enlarged drain tab that serves as both electrical connection and thermal interface to the PCB, achieving R_thJA = 60 °C/W (PCB mount) versus >150 °C/W typical for SOT-23. This allows the IRLL014 to dissipate 2.0 W on a 1" FR-4 board - more than double what a comparable SOT-23 MOSFET can handle. The IRLL014's thermal design supports higher current density in compact layouts.

Does IRLL014 have a specified body diode reverse recovery time and charge?

Yes - the IRLL014 specifies body diode reverse recovery time (t_rr) of 65–130 ns and reverse recovery charge (Q_rr) of 0.33–0.65 μC at T_J = 25 °C, I_F = 10 A, and dI/dt = 100 A/μs. These values are measured with the MOSFET symbol showing the integral p–n junction diode. The IRLL014's Q_rr enables predictable snubberless operation in flyback and buck-derived topologies.
