Product details
Overview
IRFL014TRPBF-BE3 from Vishay Siliconix is a 60 V, 2.7 A N-channel surface-mount power MOSFET in SOT-223 package, with RDS(on) = 0.20 Ω at VGS = 10 V, Qg = 11 nC, and 100 mJ single-pulse avalanche energy - used in DC-DC converters, LED drivers, and load switching where fast switching and ruggedness are required.
For engineers reviewing the IRFL014TRPBF-BE3 datasheet, IRFL014TRPBF-BE3 pinout, IRFL014TRPBF-BE3 application, or IRFL014TRPBF-BE3 equivalent, this page delivers verified electrical parameters, thermal derating behavior, body diode recovery metrics (trr = 70–140 ns), PCB-mount power dissipation (2.0 W), and SOT-223 terminal mapping for layout and reliability validation.
Technical Context
This device belongs to Vishay's third-generation high-voltage SOT-223 MOSFET family, optimized for surface-mount applications requiring >1.25 W power dissipation without heatsinks. Its enlarged drain tab improves thermal resistance to 40 °C/W (junction-to-case) and enables stable operation up to TJ = 150 °C.
The IRFL014TRPBF-BE3 features dynamic dV/dt immunity (4.5 V/ns), low gate charge (Qgd = 5.8 nC), and intrinsic body diode with VSD = 1.6 V at IS = 2.7 A - enabling robust unclamped inductive switching and ease of paralleling in medium-power SMPS designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - supports 48 V rail systems with 20 % margin against transients |
| RDS(on) | 0.20 Ω @ VGS = 10 V - limits conduction loss to ≤0.86 W at 2.7 A continuous current |
| Qg | 11 nC - enables efficient gate drive with standard 5–12 V logic-level controllers |
| EAS | 100 mJ - withstands unclamped inductive energy in relay/actuator snubberless designs |
| trr | 70–140 ns - ensures minimal reverse recovery loss during hard-switched flyback or buck operation |
| PD (PCB mount) | 2.0 W @ TA = 25 °C - achievable on 1" FR-4 board without external heatsink |
| dV/dt rating | 4.5 V/ns - suppresses false turn-on in noisy motor-drive or industrial control environments |
Pinout & Package
SOT-223 package with exposed drain tab for thermal conduction; standardized JEDEC TO-261AA outline; 3-pin configuration with G, D, S terminals arranged in linear order (Pin 1 = Gate, Pin 2 = Drain, Pin 3 = Source).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (G) | Gate | Control input; requires ≤±20 V drive; low Ciss = 300 pF minimizes driver loading |
| Pin 2 (D) | Drain | Main power output node; thermally connected to exposed copper tab for PCB heat sinking |
| Pin 3 (S) | Source | Power return path; internal source inductance LS = 6.0 nH affects high-dI/dt ringing |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount SOT-223 | Enables automated assembly and eliminates through-hole drilling; compatible with vapor-phase reflow |
| Dynamic dV/dt rating | 4.5 V/ns immunity prevents spurious turn-on in high-noise industrial switching nodes |
| Fast switching | td(on) = 10 ns, tr = 50 ns, tf = 19 ns - reduces switching losses in 100–500 kHz DC-DC stages |
| Ease of paralleling | Positive temperature coefficient of RDS(on) ensures current sharing stability across multiple devices |
| Simple drive requirements | Logic-level compatible (VGS(th) = 2.0–4.0 V); Qgs/Qgd ratio = 0.54 supports clean Miller plateau control |
Applications

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, Pb-free/halogen-free variant; identical RDS(on), Qg, and thermal specs; marking code "FA" unchanged | No functional difference; selected when RoHS-compliant tape-and-reel packaging is mandatory | Drop-in substitute for IRFL014TRPBF-BE3 in new designs requiring full halogen-free compliance |
| IRFL9014TRPBF-BE3 | P-channel counterpart: -60 V, -1.7 A, RDS(on) = 0.35 Ω; complementary topology, not pin-compatible | Used in high-side switch configurations where load referencing to VIN is required | Select only for high-side switching; requires inverted gate drive and cannot replace IRFL014TRPBF-BE3 directly |
Compared with SiHFL014TR-GE3 and IRFL9014TRPBF-BE3, the IRFL014TRPBF-BE3 offers optimal cost-performance balance for low-side switching at ≤2.7 A, with superior thermal mounting flexibility and proven avalanche ruggedness in unclamped inductive loads.

FAQ
What is the maximum continuous drain current for IRFL014TRPBF-BE3 at 100 °C case temperature?
The IRFL014TRPBF-BE3 supports 1.7 A continuous drain current at TC = 100 °C, per its absolute maximum ratings table. This derating reflects thermal limitations of the SOT-223 package; operation above this current requires active cooling or reduced ambient temperature. The IRFL014TRPBF-BE3 maintains safe SOA boundaries up to 22 A pulsed under defined test conditions.
Does IRFL014TRPBF-BE3 have a built-in body diode, and what are its key characteristics?
Yes, the IRFL014TRPBF-BE3 integrates a monolithic body diode with VSD = 1.6 V at IS = 2.7 A and TJ = 25 °C, reverse recovery time trr = 70–140 ns, and Qrr = 0.20–0.40 μC. These values are measured under standardized conditions (IF = 10 A, dI/dt = 100 A/μs) and confirm suitability for freewheeling in buck or flyback topologies. The IRFL014TRPBF-BE3 body diode is not optimized for synchronous rectification but handles typical inductive recovery reliably.
Is IRFL014TRPBF-BE3 suitable for logic-level gate drive without a dedicated driver IC?
Yes - the IRFL014TRPBF-BE3 has a gate threshold voltage VGS(th) of 2.0–4.0 V and total gate charge Qg of 11 nC, making it compatible with 3.3 V or 5 V microcontroller GPIOs when driving moderate capacitive loads. However, for reliable full-enhancement and fast switching, a buffered gate driver is recommended above 100 kHz. The IRFL014TRPBF-BE3 does not require level-shifting circuitry for standard logic-level sources.
What is the thermal resistance from junction to ambient for IRFL014TRPBF-BE3 in standard PCB mount?
The IRFL014TRPBF-BE3 has a maximum junction-to-ambient thermal resistance RthJA of 60 °C/W when mounted on a 1" square FR-4 PCB, per Vishay's test condition (Note e). This value assumes no additional copper pour or heatsinking; adding thermal vias or a 2 oz copper plane can improve performance. The IRFL014TRPBF-BE3 achieves significantly lower RthJC = 40 °C/W to the drain tab, enabling effective heat transfer to the PCB ground plane.
Can IRFL014TRPBF-BE3 be paralleled with identical units for higher current handling?
Yes - the IRFL014TRPBF-BE3 exhibits a positive temperature coefficient for RDS(on), which promotes natural current sharing among paralleled devices. Layout symmetry, matched gate drive paths, and individual gate resistors (≥10 Ω) are recommended to minimize oscillation and ensure balanced switching. The IRFL014TRPBF-BE3's low Qgd/Qg ratio further enhances paralleling stability by reducing Miller-induced cross-talk.
