Product details
Overview
IRFR110TRL from Vishay Siliconix is a 100 V, 4.3 A N-channel surface-mount power MOSFET in DPAK (TO-252) package, featuring 0.54 Ω RDS(on) at VGS = 10 V, 8.3 nC total gate charge, and repetitive avalanche rating - designed for DC-DC converters, motor control, and load switching in industrial power supplies.
For engineers reviewing the IRFR110TRL datasheet, IRFR110TRL pinout, IRFR110TRL application, or IRFR110TRL equivalent, this part supports fast-switching, parallel operation, and rugged unclamped inductive switching with verified dV/dt immunity up to 5.5 V/ns and 75 mJ single-pulse avalanche energy.
Technical Context
This third-generation TrenchFET® MOSFET uses planar silicon technology optimized for low conduction loss and robust transient handling. Its gate threshold voltage (2.0–4.0 V) ensures reliable turn-on with standard 10 V gate drivers, while its 15 pF Crss and 180 pF Ciss support high-frequency PWM operation up to several hundred kHz.
The device integrates a fast-recovery body diode (trr = 100–200 ns, Qrr = 0.44–0.88 μC) and exhibits linear derating of 0.20 W/°C at case temperature - enabling thermal management on FR-4 PCBs with 1"² copper area, where RthJA is 50 °C/W.

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 |
|---|---|---|---|
| IRLR110TRPbF | Same die, identical RDS(on), Qg, and avalanche specs; differs only in tape-and-reel packaging (TR vs. TRL) and lead finish (PbF vs. PbF-BE3) | No functional difference; both rated for surface-mount assembly and same thermal profile | Select IRFR110TRL when requiring BE3 alternate manufacturing location traceability and specified reel quantity per JESD48. |
| SiHFR110TRLPbF | Same Vishay product family; identical absolute maximum ratings, dynamic parameters, and DPAK footprint; minor process variation yields ±5% RDS(on) tolerance overlap | Drop-in compatible in all electrical and mechanical respects; validated for same automotive-grade reflow profiles | Choose SiHFR110TRLPbF if dual-sourcing from Vishay's second-source fabrication line is required for supply chain resilience. |
Compared with IRFR110TRL, IRFR110TRL's BE3 marking confirms alternate fab sourcing without parameter shift, while SiHFR110TRLPbF offers identical performance with enhanced material compliance documentation - both preserve the 0.54 Ω/8.3 nC/75 mJ core specification set critical for thermal-limited and avalanche-prone designs.

FAQ
What is the maximum continuous drain current for IRFR110TRL at 100 °C case temperature?
The IRFR110TRL supports 2.7 A continuous drain current at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This derated value reflects thermal limitations of the DPAK package under sustained power dissipation and must be validated against actual board layout and ambient conditions. The IRFR110TRL maintains full 4.3 A rating only at TC = 25 °C.
Does IRFR110TRL have a built-in body diode, and what are its key recovery characteristics?
Yes, the IRFR110TRL integrates a monolithic body diode with typical reverse recovery time (trr) of 100–200 ns and reverse recovery charge (Qrr) of 0.44–0.88 μC at TJ = 25 °C, IF = 5.6 A, and dI/dt = 100 A/μs. These values enable efficient freewheeling in synchronous rectification and inductive load commutation without external diode supplementation.
What is the gate threshold voltage range for IRFR110TRL, and how does it affect drive requirements?
The IRFR110TRL has a gate threshold voltage (VGS(th)) range of 2.0 V to 4.0 V at ID = 250 μA. This allows reliable turn-on with standard 5 V or 10 V logic-level gate drivers, but full enhancement requires ≥10 V to achieve the specified 0.54 Ω RDS(on). Driving below 4.5 V risks incomplete saturation and excessive conduction loss.
Is IRFR110TRL suitable for avalanche operation, and what energy level is rated?
Yes, the IRFR110TRL is explicitly rated for repetitive avalanche operation with 4.3 A IAR and 2.5 mJ EAR, and single-pulse avalanche energy of 75 mJ. These ratings are validated per test condition b in the datasheet (VDD = 25 V, L = 8.1 mH, Rg = 25 Ω), confirming robustness in unclamped inductive switching circuits such as relay drivers and solenoid controls.
What thermal resistance values apply to IRFR110TRL in a standard PCB-mount configuration?
In a standard 1"² FR-4 PCB mount, the IRFR110TRL exhibits RthJA = 50 °C/W and RthJC = 5.0 °C/W. The 50 °C/W value governs junction-to-ambient rise under natural convection, while the 5.0 °C/W enables accurate junction temperature estimation when heatsinking the drain pad - critical for validating safe operating area in continuous 2.5 W dissipation scenarios.
