Product details

Overview

IRLL014PBF from Vishay Siliconix is a logic-level N-channel enhancement-mode 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 delivers fast switching (t_r = 110 ns), low gate charge (Q_g = 8.4 nC), and robust avalanche capability (E_AS = 100 mJ), enabling use in compact DC-DC converters and load-switching circuits.

For engineers reviewing the IRLL014PBF datasheet, IRLL014PBF pinout, IRLL014PBF application, or IRLL014PBF equivalent, key selection criteria include logic-level gate drive compatibility (V_GS(th) = 1.0–2.0 V), thermal performance on PCB mount (R_thJA = 60 °C/W), body diode recovery time (t_rr = 65–130 ns), and SOT-223 footprint suitability for high-density surface-mount designs.

Technical Context

This MOSFET employs planar V-groove technology optimized for low R_DS(on) and stable threshold voltage across temperature. Its dynamic dV/dt rating of 4.5 V/ns supports reliable operation in noisy switching environments without spurious turn-on.

The device integrates a monolithic body diode with V_SD = 1.6 V at I_S = 2.7 A and t_rr = 65–130 ns, enabling synchronous rectification and unclamped inductive switching applications where controlled diode recovery is critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - maximum blocking voltage for 24 V input systems with margin
R_DS(on) @ V_GS = 5 V	0.20 Ω - enables ≤0.86 W conduction loss at 2.7 A, suitable for thermally constrained PCBs
Q_g	8.4 nC - supports efficient gate driving with standard logic-level drivers (e.g., microcontroller GPIO)
t_r/t_f	110 ns / 26 ns - reduces switching losses in 100–500 kHz DC-DC topologies
E_AS	100 mJ - withstands single-pulse inductive energy without failure in motor drive or solenoid control
T_J Range	−55 to +150 °C - qualified for industrial ambient and under-hood automotive auxiliary functions

Pinout & Package

SOT-223 package with exposed drain tab for enhanced thermal conduction; 3.3 mm × 6.7 mm footprint; 1.8 mm height; JEDEC TO-261AA compliant; designed for vapor-phase, infrared, or wave soldering.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control electrode	Accepts logic-level drive (1.0–2.0 V threshold); requires <3.5 nC charge to reach full enhancement
D (Drain)	High-side power terminal	Internally connected to exposed copper tab; primary heat path to PCB copper pour
S (Source)	Reference/return node	Common return for gate drive and load current; defines local ground reference for control circuitry

Key Features

Feature	Design Value
Logic-level gate drive	V_GS(th) = 1.0–2.0 V ensures full enhancement from 3.3 V or 5 V microcontrollers without level-shifting
Dynamic dV/dt immunity	Rated 4.5 V/ns - prevents false turn-on during high-slew-rate switching transients
Enhanced thermal performance	PCB-mounted P_D = 2.0 W - 60% higher than standard SOT-23 equivalents due to enlarged drain tab
Fast body diode recovery	t_rr = 65–130 ns - minimizes reverse-recovery losses in buck converter freewheeling paths

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SiHLL014TR-GE3	Same die, Pb-free/halogen-free construction; identical R_DS(on), Q_g, and thermal specs	No functional difference; preferred for RoHS-compliant production	Select SiHLL014TR-GE3 when lead-free compliance is mandatory per IPC-J-STD-609
IRLML0030TRPBF	Lower V_DS (30 V), lower R_DS(on) (0.055 Ω @ 4.5 V), SOT-23 package, lower I_D (2.0 A)	Not suitable for 48 V bus or high-energy inductive loads; limited thermal dissipation (1.3 W PCB mount)	Choose IRLML0030TRPBF only for ≤12 V, low-power (<5 W) applications where board space is critical

Compared with SiHLL014TR-GE3, IRLL014PBF offers identical electrical performance but differs in marking and packaging; versus IRLML0030TRPBF, IRLL014PBF provides higher voltage rating and superior thermal capability at the cost of larger footprint-making it optimal for 24–48 V industrial power stages requiring reliability and margin.

FAQ

What is the maximum continuous drain current for IRLL014PBF at 100 °C case temperature?

The IRLL014PBF supports 1.7 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the SOT-223 package under sustained high-temperature operation and must be verified against actual PCB layout and airflow conditions in the final design.

Does IRLL014PBF have avalanche capability, and how is it rated?

Yes, IRLL014PBF is rated for unclamped inductive switching with single-pulse avalanche energy E_AS = 100 mJ (V_DD = 25 V, I_AS = 2.7 A). This rating is validated per test condition Fig. 12 and enables safe operation in relay drivers and solenoid controls without external snubbers-provided pulse width and duty cycle remain within datasheet limits.

Can IRLL014PBF be driven directly from a 3.3 V microcontroller GPIO?

Yes, IRLL014PBF features a logic-level gate threshold (V_GS(th) = 1.0–2.0 V) and is fully enhanced at V_GS = 4.0 V (R_DS(on) = 0.28 Ω) and V_GS = 5.0 V (R_DS(on) = 0.20 Ω). A 3.3 V GPIO can reliably switch the IRLL014PBF in low-frequency applications; for >100 kHz PWM, verify gate drive strength meets Q_g = 8.4 nC requirement.

What is the thermal resistance from junction to ambient for IRLL014PBF in standard PCB mount?

When mounted on a 1" square FR-4 PCB, IRLL014PBF has R_thJA = 60 °C/W. This value assumes minimum copper area per JEDEC standards and is used to calculate worst-case junction temperature: T_J = T_A + (P_D × R_thJA). For higher power, thermal vias and extended copper pours significantly improve this metric.

Is IRLL014PBF pin-compatible with other SOT-223 N-channel MOSFETs?

IRLL014PBF uses standard SOT-223 pinout (G-D-S, with D connected to tab), matching industry-standard layouts. However, pin compatibility alone does not guarantee functional equivalence-always verify V_DS, R_DS(on), Q_g, and thermal specs. The IRLL014PBF pinout is documented in Figure 14 of its datasheet and confirmed on Vishay's official package drawing 91363.
