Product details
Overview
IRLL014TR from Vishay Siliconix is a logic-level N-channel enhancement-mode power MOSFET in SOT-223 package, rated for 60 V VDS, 2.7 A continuous drain current at TC = 25 °C, 0.20 Ω RDS(on) at VGS = 5 V, and optimized for low-voltage switching in DC-DC converters and load-switching applications.
For engineers reviewing the IRLL014TR datasheet, IRLL014TR pinout, IRLL014TR application, or IRLL014TR equivalent, this device supports fast switching (9.3 ns turn-on delay), avalanche-rated operation (100 mJ single-pulse EAS), and PCB-mount thermal performance up to 2.0 W with RthJA = 60 °C/W - critical for space-constrained industrial and automotive auxiliary power designs.
Technical Context
This MOSFET employs planar V-groove silicon technology enabling stable threshold voltage (1.0–2.0 V) and low gate charge (Qg = 8.4 nC), supporting efficient drive from 3.3 V or 5 V microcontrollers without external level-shifting. Its body diode exhibits trr = 65–130 ns and Qrr = 0.33–0.65 μC, suitable for synchronous rectification and flyback snubberless topologies.
The SOT-223 package integrates an exposed drain tab for direct PCB heatsinking, delivering >1.25 W power dissipation on FR-4 boards - significantly higher than standard SOT-23 devices - while maintaining surface-mount compatibility with automated pick-and-place systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - supports 48 V rail switching and transient overvoltage tolerance in industrial control inputs |
| RDS(on) @ VGS = 5 V | 0.20 Ω - enables <1.1 W conduction loss at 2.3 A, reducing thermal burden in compact PCB layouts |
| Qg | 8.4 nC - allows full switching within 100 ns using 12 Ω gate resistor, minimizing drive power in battery-powered systems |
| ID (continuous, TC = 25 °C) | 2.7 A - sufficient for 5–12 V load switches driving solenoids, LEDs, or small motors |
| EAS | 100 mJ - withstands unclamped inductive energy in relay drivers and motor H-bridge freewheeling paths |
| tr/tf | 110 ns / 26 ns - reduces switching losses below 500 kHz, supporting high-frequency SMPS secondary-side switching |
| VGS(th) | 1.0–2.0 V - ensures reliable turn-on with 3.3 V GPIO, eliminating need for gate boosters in MCU-driven loads |
Pinout & Package
SOT-223 package with molded plastic body, exposed drain tab (Pin 4) for thermal conduction, and three signal leads: Gate (Pin 1), Drain (Pin 2), Source (Pin 3). Mounting requires 1" square FR-4 PCB area for rated 2.0 W dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (G) | Gate terminal | Logic-level input accepting 3.3 V/5 V drive; 100 nA leakage ensures low standby current in always-on systems |
| Pin 2 (D) | Drain terminal | High-side switch node; connected internally to exposed metal tab for thermal path to PCB copper pour |
| Pin 3 (S) | Source terminal | Power return path; referenced to system ground in low-side configurations or floating in high-side setups |
| Tab (D) | Drain thermal pad | Not electrically isolated - must be soldered to large copper area for thermal management and EMI reduction |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Guaranteed turn-on at VGS = 4.0 V (RDS(on) ≤ 0.28 Ω), enabling direct interface with 3.3 V microcontrollers |
| Dynamic dV/dt rating | 4.5 V/ns immunity prevents false triggering during fast bus transients in motor control and power supply rails |
| Avalanche energy rating | 100 mJ single-pulse EAS allows robust operation in inductive load switching without external snubbers |
| Surface-mount packaging | SOT-223 footprint compatible with standard reflow profiles (peak 300 °C/10 s), supporting high-volume automated assembly |
| Body diode recovery | 65–130 ns trr and 0.33–0.65 μC Qrr reduce switching losses in freewheeling and synchronous rectifier applications |

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, alternate lead-free plating (GE3 vs BE3); identical RDS(on), Qg, and thermal specs | No functional difference; GE3 variant uses different Pb-free finish but same SOT-223 mechanical outline | Select based on distributor stock and RoHS compliance documentation requirements |
| IRLML0030TRPBF | Lower VDS (30 V), lower RDS(on) (0.045 Ω @ 4.5 V), SOT-23 package - smaller footprint but 1.3 W max power | Not suitable for 48 V systems; limited to sub-2 A loads due to thermal constraints of SOT-23 | Choose only for space-critical 3.3/5 V logic-level switching where <1.5 A current and <30 V operation apply |
Compared with SiHLL014TR-GE3, IRLL014TR offers identical electrical performance with alternate manufacturing traceability; versus IRLML0030TRPBF, IRLL014TR provides higher voltage margin and superior thermal handling at the cost of larger SOT-223 footprint - critical for industrial 48 V auxiliary power and motor control.

FAQ
What is the maximum continuous drain current for IRLL014TR at 100 °C case temperature?
The IRLL014TR supports 1.7 A continuous drain current at TC = 100 °C, derated linearly from 2.7 A at 25 °C using a factor of 0.025 W/°C. This value is confirmed in the Absolute Maximum Ratings table and reflects safe operation under sustained thermal load when mounted on a 1" square FR-4 PCB per datasheet note "e".
Does IRLL014TR require a gate resistor for 3.3 V MCU drive?
Yes, IRLL014TR benefits from a series gate resistor (typically 10–47 Ω) even with 3.3 V drive to control dI/dt and suppress ringing caused by LS = 6.0 nH and LD = 4.0 nH parasitics. The device's 3.5 nC Qgs ensures fast turn-on, but uncontrolled edge rates may induce EMI or shoot-through in half-bridge configurations.
Can IRLL014TR replace a standard 2N7002 in high-current applications?
No - while both are logic-level N-channel MOSFETs, IRLL014TR delivers 2.7 A continuous current and 0.20 Ω RDS(on) versus 2N7002's 0.3 A and 3.0 Ω. IRLL014TR's SOT-223 package also provides 2× the thermal capability. Substituting requires verifying layout changes for the larger footprint and updated gate drive timing.
What is the body diode forward voltage of IRLL014TR at 2.7 A?
The body diode forward voltage (VSD) of IRLL014TR is 1.6 V maximum at TJ = 25 °C and IS = 2.7 A with VGS = 0 V. This value is specified in the Drain-Source Body Diode Characteristics table and impacts conduction loss in freewheeling paths and reverse recovery behavior.
Is IRLL014TR suitable for avalanche energy handling in relay coil suppression?
Yes - IRLL014TR is fully rated for unclamped inductive switching with EAS = 100 mJ (single-pulse) and IAR = 2.7 A, making it appropriate for relay and solenoid coil suppression without external snubbers. The datasheet validates this under test condition VDD = 25 V, L = 16 mH, and Rg = 25 Ω per Figure 12.
