Product details

Overview

IRFL014TR from Vishay Siliconix is a 60 V, 2.7 A N-channel enhancement-mode power MOSFET in SOT-223 package, with R_DS(on) = 0.20 Ω at V_GS = 10 V, Q_g = 11 nC, and 100 mJ single-pulse avalanche energy-designed for DC-DC converters, motor drivers, and load-switching in industrial and consumer power supplies.

For engineers reviewing the IRFL014TR datasheet, IRFL014TR pinout, IRFL014TR application, or IRFL014TR equivalent, key selection criteria include its surface-mount SOT-223 thermal performance (2.0 W PCB mount), fast switching (t_r = 50 ns), dynamic dV/dt rating (4.5 V/ns), and gate drive simplicity (V_GS(th) = 2.0–4.0 V).

Technical Context

This MOSFET employs third-generation silicon technology optimized for ruggedized switching in medium-power surface-mount applications. Its design integrates low gate charge (Q_g = 11 nC) and low output capacitance (C_oss = 160 pF) to minimize switching losses while maintaining high avalanche robustness (E_AS = 100 mJ).

The device operates as a unidirectional voltage-controlled switch with an integral body diode (V_SD = 1.6 V, t_rr = 70–140 ns). It supports linear-mode operation within SOA limits and features ±20 V gate-source voltage tolerance and 150 °C maximum junction temperature.

Key Specifications

I_D (continuous)	2.7 A @ T_C = 25 °C - Continuous current capability under heatsink conditions; derates to 1.7 A at 100 °C case.
E_AS	100 mJ - Unclamped inductive switching energy handling; supports reliable operation in relay/snubberless flyback designs.
dV/dt rating	4.5 V/ns - Immunity to parasitic turn-on during high-speed commutation; reduces need for external gate clamping.

Key Features

Feature	Design Value
Surface-mount SOT-223	Enables automated assembly and eliminates through-hole drilling; tab improves thermal transfer over standard SOT-23.
Dynamic dV/dt rating	4.5 V/ns immunity prevents false triggering in noisy switching nodes without added gate resistors or clamps.
Fast switching	10 ns turn-on delay + 50 ns rise time allows >500 kHz PWM operation with low overlap loss.
Ease of paralleling	Positive temperature coefficient of R_DS(on) ensures self-balancing current sharing when multiple IRFL014TR devices are used.

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
SiHFL014TR-GE3	Same die, identical R_DS(on), Q_g, and SOA; differs only in lead-free plating specification and manufacturing location (GE3 vs BE3).	No functional difference; qualified for same industrial and commercial temperature ranges and PCB mount profiles.	Select SiHFL014TR-GE3 if RoHS-compliant tin-silver-copper plating is required per procurement policy.
IRFL9014TRPbF	P-channel counterpart (−60 V, −1.7 A); complementary topology only; not pin-compatible or functionally interchangeable.	Used in high-side switching configurations where N-channel would require bootstrap or isolated gate drive.	Choose IRFL9014TRPbF only for high-side load switch designs requiring negative V_GS control; not a drop-in replacement.

Compared with IRFL014TR, SiHFL014TR-GE3 offers identical electrical and thermal behavior with alternate plating compliance, while IRFL9014TRPbF serves a fundamentally different circuit role (high-side vs low-side) and requires layout redesign.

FAQ

What is the maximum continuous drain current for IRFL014TR at 100 °C case temperature?

The IRFL014TR 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 current depends on copper area, airflow, and ambient conditions. The IRFL014TR datasheet specifies linear derating beyond 25 °C at 0.025 W/°C for junction-to-case and 0.017 W/°C for PCB-mounted configurations.

Does IRFL014TR have avalanche capability, and how is it rated?

Yes, the IRFL014TR is rated for single-pulse avalanche energy of 100 mJ under specified test conditions (V_DD = 25 V, L = 16 mH, I_AS = 2.7 A). This rating applies to unclamped inductive switching events and is validated per JEDEC standards. The IRFL014TR does not specify repetitive avalanche capability, so designers must ensure system-level protection or limit duty cycle accordingly.

Can IRFL014TR be driven directly from a 3.3 V microcontroller GPIO?

The IRFL014TR has a gate threshold voltage range of 2.0–4.0 V, meaning a 3.3 V GPIO may partially enhance the channel but will not achieve full R_DS(on) = 0.20 Ω. At V_GS = 3.3 V, R_DS(on) rises significantly (typical ~0.45 Ω), increasing conduction loss. For optimal performance, the IRFL014TR requires ≥10 V gate drive; use a level shifter or gate driver IC when interfacing with 3.3 V logic.

What is the thermal resistance from junction to ambient for IRFL014TR in standard PCB mount?

When mounted on a 1" square FR-4 PCB, the IRFL014TR has a maximum junction-to-ambient thermal resistance (R_thJA) of 60 °C/W. This value assumes no additional heatsinking; adding copper pour or thermal vias can improve performance. The junction-to-case (R_thJC) is 40 °C/W, and the exposed drain tab must be soldered to maximize heat transfer-critical for sustaining 2.0 W power dissipation.

Is IRFL014TR suitable for linear-mode (active-region) operation?

Yes, the IRFL014TR is characterized for linear-mode operation within its Safe Operating Area (SOA), as shown in Figure 8 of its datasheet. It supports DC and pulsed operation with voltage and current combinations bounded by thermal and avalanche limits. However, sustained linear use requires careful thermal design due to power dissipation concentrated at the die; the IRFL014TR is not optimized for extended analog pass-transistor roles like LDOs.
