Product details
Overview
IRFR3910TRL from Infineon Technologies (formerly International Rectifier) is a 100V, 16A N-channel enhancement-mode power MOSFET in TO-252AA (D-Pak) surface-mount package, featuring 0.115Ω RDS(on) at VGS = 10V, fully avalanche-rated, and optimized for DC-DC converters, motor drives, and load switching in industrial power supplies.
For engineers reviewing the IRFR3910TRL datasheet, IRFR3910TRL pinout, IRFR3910TRL application, or IRFR3910TRL equivalent, key selection criteria include its 1.9°C/W junction-to-case thermal resistance, 44nC total gate charge, 130–190ns reverse recovery time, and validated unclamped inductive switching capability up to 150mJ single-pulse avalanche energy.
Technical Context
This HEXFET® device uses fifth-generation silicon process technology to achieve ultra-low on-resistance per die area while maintaining ruggedness against repetitive and single-pulse avalanche stress. Its body diode exhibits 1.3V forward voltage at 9.0A and 25°C, with 650–970nC reverse recovery charge under di/dt = 100A/µs.
The MOSFET operates across –55°C to +175°C junction temperature range, supports ±20V gate drive, and delivers fast switching with 6.4ns turn-on delay, 27ns rise time, 37ns turn-off delay, and 25ns fall time into 12Ω gate resistor-enabling high-frequency PWM control in synchronous rectification and half-bridge topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 100V - Maximum blocking voltage before avalanche onset; sets upper limit for bus voltage in 48V systems. |
| RDS(on) | 0.115Ω @ VGS = 10V, ID = 10A - Determines conduction loss: ~1.0W at 9.5A continuous drain current. |
| ID (TC = 25°C) | 16A - Continuous current rating under ideal heatsinking; derates linearly by 0.53W/°C above 25°C case temp. |
| EAS | 150mJ - Single-pulse avalanche energy rating; enables reliable operation during inductive turn-off transients without snubbers. |
| Qg | 44nC - Total gate charge; defines driver strength requirement: ≥2.2A peak for 20ns gate rise under 10V swing. |
| Ciss | 640pF @ VDS = 0V - Input capacitance affecting gate drive loop stability and EMI filtering design. |
| trr | 130–190ns - Body diode reverse recovery time; impacts shoot-through risk and dead-time setting in bridge circuits. |
Pinout & Package
TO-252AA (D-Pak) surface-mount package with exposed drain pad for thermal conduction and mechanical anchoring. Leads are gull-wing formed for reflow compatibility; recommended footprint per AN-994.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - Gate | Control electrode | High-impedance input requiring low-inductance gate drive path; sensitive to ESD (±20V absolute max). |
| 2 - Drain | Power output terminal | Internally connected to exposed copper pad; primary heat transfer path to PCB ground plane or heatsink. |
| 3 - Source | Reference node / return path | Common reference for gate drive and load current; connects to power ground or low-side switch node. |
| 4 - Drain (tab) | Secondary drain connection | Electrically identical to Pin 2; provides redundant current path and enhanced thermal dissipation via soldered tab. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) | 0.115Ω reduces I²R conduction losses by >30% vs. legacy D-Pak MOSFETs at same voltage class. |
| Fully avalanche rated | 150mJ single-pulse and 7.9mJ repetitive avalanche energy enable robust operation without external clamping in inductive loads. |
| Fast switching performance | 6.4ns td(on), 27ns tr, 37ns td(off), 25ns tf support >500kHz PWM frequencies with minimal switching loss. |
| Optimized body diode | 1.3V VSD at 9.0A and 130–190ns trr reduce freewheeling loss and improve efficiency in synchronous rectifiers. |
| Surface-mount TO-252AA | Thermally efficient D-Pak layout allows 79W power dissipation at TC = 25°C with standard PCB copper area. |

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 |
|---|---|---|---|
| STP16NF10 | TO-220 package; higher RDS(on) = 0.18Ω; lower Qg = 32nC; no specified avalanche rating. | Requires through-hole assembly and external heatsink; unsuitable for unclamped inductive switching. | Select only if board space permits TO-220 and avalanche robustness is not required. |
| IXTP16N10P | TO-220FP package; RDS(on) = 0.12Ω; EAS = 120mJ; slower switching (tr = 45ns). | Lower thermal resistance (1.5°C/W) but larger footprint; limited to ≤200kHz due to higher Ciss. | Prefer when higher avalanche margin than IRFR3910TRL is needed but surface-mount is not mandatory. |
Compared with STP16NF10 and IXTP16N10P, IRFR3910TRL offers superior surface-mount integration, lowest conduction loss in D-Pak form factor, and highest verified avalanche energy-making it optimal for space-constrained, high-reliability industrial switching where thermal and transient robustness are critical.

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The IRFR3910TRL supports 12A continuous drain current at TC = 100°C, as specified in the Absolute Maximum Ratings table. This reflects thermal derating from the 16A rating at 25°C, governed by the 0.53W/°C linear derating factor and 1.9°C/W junction-to-case thermal resistance.
Is the IRFR3910TRL suitable for use in synchronous rectification?
Yes-the device features a low 1.3V body diode forward voltage at 9.0A and fast 130–190ns reverse recovery time, enabling efficient synchronous rectification in buck and flyback topologies. Its 0.115Ω RDS(on) further reduces conduction loss compared to Schottky alternatives at >30V output.
Does the TO-252AA package require special PCB layout considerations?
Yes-the exposed drain pad must be connected to a minimum 1"² copper area on the PCB layer for thermal performance. Per AN-994, use multiple thermal vias (≥8 × 0.3mm) under the pad to inner ground planes, and maintain ≥0.5mm clearance from adjacent traces to avoid solder bridging during reflow.
Can the IRFR3910TRL replace the IRFR3710 in an existing design?
No-while both are D-Pak N-MOSFETs, the IRFR3710 has VDSS = 100V but RDS(on) = 0.055Ω and Qg = 85nC. Substituting IRFR3910TRL would increase conduction loss by ~110% and reduce gate drive demand, but compromise efficiency and thermal margin in high-current operation.
