Product details
Overview
IRFR110TR 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 IRFR110TR datasheet, IRFR110TR pinout, IRFR110TR application, or IRFR110TR 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 N-channel enhancement-mode MOSFET uses third-generation trench-gate silicon technology optimized for low conduction loss and high switching efficiency. Its dynamic dV/dt rating and repetitive avalanche capability enable robust operation in inductive load circuits without external snubbers.
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-supporting thermal management on standard FR-4 PCBs with 1"² copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - Maximum drain-source blocking voltage for use in ≤100 V bus applications |
| RDS(on) @ VGS = 10 V | 0.54 Ω - Conduction loss of ≤5.9 W at 4.3 A continuous drain current |
| Qg | 8.3 nC - Gate drive energy requirement enabling <15 ns turn-off delay with 24 Ω gate resistor |
| ID (TC = 25 °C) | 4.3 A - Continuous current capability with heatsink or high-copper PCB mounting |
| EAS | 75 mJ - Single-pulse avalanche energy tolerance for reliable unclamped inductive switching |
| dV/dt Rating | 5.5 V/ns - Immunity to false turn-on during high-slew-rate transients in motor drives |
| RthJC | 5.0 °C/W - Junction-to-case thermal resistance enabling direct heatsink attachment via drain tab |
Pinout & Package
DPAK (TO-252) surface-mount package with exposed drain pad for thermal and electrical connection; dimensions per JEDEC outline (Version 1: facility code Y), including 6.35 mm × 6.73 mm body width and 9.40–10.41 mm length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (G) | Gate | Control terminal requiring ≤±20 V drive; 2.3 nC gate-source charge enables logic-level compatibility with 5 V microcontrollers when used with appropriate gate driver |
| Pin 2 (D) | Drain | Main power output terminal; electrically and thermally connected to exposed copper pad-must be soldered to ≥1"² PCB copper for 2.5 W ambient-rated dissipation |
| Pin 3 (S) | Source | Power return path and reference for gate drive; internal source inductance of 7.5 nH impacts high-frequency switching stability and requires careful layout |
Key Features

|---|---|
| Repetitive avalanche rated | Supports 4.3 A IAR and 2.5 mJ EAR without degradation-enables reliable operation in flyback and buck-boost topologies with no added clamping circuitry |
| Dynamic dV/dt rating | 5.5 V/ns immunity prevents spurious turn-on during rapid voltage transients in half-bridge and motor phase-leg configurations |
| Fast switching | 15 ns td(off) and 9.4 ns tf at VDD = 50 V reduce switching losses in 100–500 kHz SMPS designs |
| Surface-mount (DPAK) | Compatible with vapor-phase, infrared, and wave soldering; thermal pad allows direct heatsinking on PCB without mechanical fasteners |
| Easy paralleling | Low RDS(on) tolerance and positive temperature coefficient enable stable current sharing across multiple IRFR110TR devices in high-current rails |

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-but TO-220AB package with isolated tab and higher RthJC (3.0 °C/W vs. 5.0 °C/W) | Requires mechanical mounting and insulation; unsuitable for space-constrained SMT layouts | Select when board-level heatsinking is impractical and discrete heatsink integration is preferred |
| SiHFR110TR-GE3 | Functionally identical second-source part from same Vishay fab; Pb-free/halogen-free construction, same DPAK footprint and pinout | No functional or layout differences; qualified for same automotive and industrial temperature ranges (−55 to +150 °C) | Preferred for RoHS-compliant production; fully interchangeable with IRFR110TR in existing designs |
Compared with IRFR110TR, IRLR110TRPbF trades surface-mount convenience for superior thermal performance in through-hole systems, while SiHFR110TR-GE3 offers identical electrical behavior with enhanced environmental compliance-making it the drop-in replacement for new designs requiring halogen-free materials.

FAQ
What is the maximum continuous drain current for IRFR110TR at 100 °C case temperature?
The IRFR110TR supports 2.7 A continuous drain current at TC = 100 °C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limitations of the DPAK package mounted on standard PCBs; actual current capability increases with improved heatsinking or lower ambient temperatures. The IRFR110TR maintains safe operation up to 150 °C junction temperature under pulsed conditions.
Does IRFR110TR have a built-in body diode, and what are its key parameters?
Yes, the IRFR110TR integrates a monolithic body diode with typical forward voltage VSD = 2.5 V at IS = 4.3 A and TJ = 25 °C. Its reverse recovery time trr is 100–200 ns, and reverse recovery charge Qrr is 0.44–0.88 μC under standardized test conditions (IF = 5.6 A, dI/dt = 100 A/μs). These values confirm suitability for freewheeling in non-synchronous buck converters.
Can IRFR110TR be used in avalanche mode, and what are the limits?
Yes, the IRFR110TR is explicitly rated for repetitive avalanche operation: IAR = 4.3 A and EAR = 2.5 mJ per pulse, with pulse width limited by junction temperature. It also supports single-pulse avalanche energy EAS = 75 mJ. These ratings are validated per Figure 12 in the datasheet and allow safe operation in unclamped inductive switching without external protection components.
What is the gate threshold voltage range for IRFR110TR, and how does it affect drive requirements?
The IRFR110TR has a gate-source threshold voltage VGS(th) ranging from 2.0 V to 4.0 V at TJ = 25 °C. This ensures reliable turn-on with standard 5 V logic-level drivers, though full enhancement (RDS(on) = 0.54 Ω) requires VGS ≥ 10 V. The IRFR110TR's positive temperature coefficient further enhances current sharing in parallel configurations.
Is IRFR110TR compatible with lead-free reflow soldering processes?
Yes, the IRFR110TR is qualified for lead-free reflow soldering with peak temperature up to 260 °C for 10 seconds, as stated in its Absolute Maximum Ratings. Its DPAK (TO-252) package meets JEDEC standards for surface-mount assembly, and the "PbF-BE3" suffix confirms lead-free and halogen-free construction compliant with RoHS Directive 2011/65/EU.
