Product details
Overview
IRFR110TRR 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 IRFR110TRR datasheet, IRFR110TRR pinout, IRFR110TRR application, or IRFR110TRR equivalent, this page delivers verified electrical specs, thermal derating behavior, body diode recovery characteristics (trr = 100–200 ns), PCB-mount power dissipation (2.5 W), and validated alternatives for high-reliability discrete power switching.
Technical Context
This third-generation TrenchFET® MOSFET uses planar silicon process to achieve low on-resistance with rugged unclamped inductive switching capability (EAS = 75 mJ). Its gate threshold voltage (2.0–4.0 V) supports standard 10 V gate drive while maintaining noise immunity.
Thermal design relies on junction-to-case resistance of 5.0 °C/W and junction-to-ambient (PCB mount) of 50 °C/W-enabling stable operation up to 150 °C junction temperature when mounted on 1" FR-4 PCB. The integrated body diode exhibits 2.5 V forward drop at 4.3 A and controlled dV/dt recovery (5.5 V/ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - supports 48 V bus systems with 2× safety margin against transients |
| RDS(on) | 0.54 Ω @ VGS = 10 V - enables ≤2.3 W conduction loss at 4.3 A continuous current |
| Qg | 8.3 nC - determines gate driver power requirement and switching speed in hard-switched topologies |
| ID (TC = 100 °C) | 2.7 A - defines maximum continuous current under thermally constrained PCB mounting |
| EAS | 75 mJ - quantifies single-pulse energy handling during inductive turn-off without external snubber |
| trr | 100–200 ns - impacts reverse recovery losses and EMI in synchronous rectification or half-bridge configurations |
| RthJC | 5.0 °C/W - confirms efficient heat transfer to heatsink or copper pour via drain pad |
Pinout & Package
DPAK (TO-252) package with exposed drain pad for thermal and electrical connection; surface-mount compatible with vapor phase, infrared, or wave soldering per JEDEC MO-238.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (G) | Gate | Controls channel conduction; requires ≤±20 V drive; 2.3 nC gate-source charge defines Miller plateau timing |
| Pin 2 (D) | Drain | Main high-side power terminal; electrically and thermally connected to exposed backside metal pad |
| Pin 3 (S) | Source | Power return path and gate reference; internal source inductance (7.5 nH) affects high-speed switching ringing |
Key Features
| Feature | Design Value |
|---|---|
| Repetitive avalanche rated | Supports 4.3 A IAR and 2.5 mJ EAR without degradation-enables robust operation in inductive load switching |
| Dynamic dV/dt rating | 5.5 V/ns minimum-reduces risk of false turn-on in high-noise motor drive or SMPS environments |
| Fast switching | td(on) = 6.9 ns, tr = 16 ns, td(off) = 15 ns, tf = 9.4 ns-minimizes transition losses at 100–500 kHz frequencies |
| Surface-mount (DPAK) | Compatible with automated assembly; thermal pad enables 2.5 W dissipation on 1" FR-4 PCB without heatsink |
| Low Qgd/Qg ratio | 3.8/8.3 ≈ 46%-improves controllability during Miller region and reduces susceptibility to shoot-through |
Applications
| DC-DC Converter Secondary Side | Industrial Motor Driver Half-Bridge |
|---|---|
Use Scenario: Synchronous rectification in 12–48 V input isolated flyback or forward converters. IC Role / Device Role / Timing Role: Low-side switch replacing Schottky diode to reduce conduction loss and improve efficiency. Use Value: 0.54 Ω RDS(on) cuts rectifier loss by >40% vs. 40 V Schottky at 3 A, enabling >92% efficiency at full load. | Use Scenario: High-side or low-side switching in 24 V brushed DC motor H-bridge drivers. IC Role / Device Role / Timing Role: Power stage transistor controlling direction/speed via PWM at ≤20 kHz. Use Value: Repetitive avalanche rating absorbs inductive kickback during PWM commutation without external clamping. |

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 ratings; differs only in lead-free plating and tape/reel packaging code | No functional difference; fully interchangeable in layout and drive circuitry | Select when RoHS-compliant finish and standard tape/reel logistics are required |
| STP12NF10 | Higher RDS(on) (0.85 Ω), lower ID (12 A @ TC = 25 °C), no specified EAS rating; TO-220 package | Requires heatsink for >1.5 A continuous; unsuitable for surface-mount-only designs or unclamped inductive switching | Choose only if through-hole mounting and higher voltage margin (100 V) are acceptable trade-offs for cost |
Compared with IRFR110TRR, IRFL110TRPbF offers identical electrical performance in a functionally equivalent package, while STP12NF10 provides higher current rating but lacks surface-mount compatibility and avalanche ruggedness-making IRFR110TRR optimal for space-constrained, high-reliability industrial switching.

FAQ
What is the maximum continuous drain current for IRFR110TRR at 100 °C case temperature?
The IRFR110TRR supports 2.7 A continuous drain current at TC = 100 °C, as defined by its linear derating factor of 0.20 W/°C from the 25 W maximum power dissipation at TC = 25 °C. This value assumes proper PCB thermal management using a 1" square FR-4 copper area per Vishay's recommended layout.
Does IRFR110TRR have an integrated body diode, and what are its key parameters?
Yes, IRFR110TRR includes an integral body diode rated for 4.3 A continuous source-drain current. Key parameters include VSD = 2.5 V at 4.3 A and TJ = 25 °C, reverse recovery time trr = 100–200 ns, and reverse recovery charge Qrr = 0.44–0.88 μC-critical for evaluating commutation losses in synchronous rectifiers.
What is the gate threshold voltage range for IRFR110TRR, and how does it affect drive requirements?
The IRFR110TRR has a gate threshold voltage VGS(th) of 2.0–4.0 V at ID = 250 μA. This range ensures reliable turn-on with standard 5 V or 10 V logic-level gate drivers while providing noise margin against spurious triggering in noisy industrial environments.
Can IRFR110TRR be used in avalanche mode, and what are the rated conditions?
Yes, IRFR110TRR is repetitively avalanche rated with IAR = 4.3 A and EAR = 2.5 mJ per pulse. Single-pulse avalanche energy is rated at 75 mJ (EAS) under conditions of VDD = 25 V, L = 8.1 mH, Rg = 25 Ω, and starting TJ = 25 °C-validating use in inductive load switching without external protection.
What PCB layout considerations are recommended for optimal thermal performance of IRFR110TRR?
Vishay recommends a minimum 1" square FR-4 PCB copper area for the drain pad to achieve 2.5 W power dissipation. Application Note 826 specifies pad dimensions: 0.224" × 0.243" (5.69 mm × 6.18 mm) for the central thermal pad, with 0.055" (1.397 mm) clearance to adjacent traces to minimize thermal coupling and ensure consistent solder reflow.
