Product details
Overview
IRLR120NTRLPBF from Infineon Technologies is a 100V, 10A N-channel enhancement-mode power MOSFET in D-Pak (TO-252) package, featuring RDS(on) = 0.185Ω @ VGS = 10V, fully avalanche-rated, and lead-free. It serves as a high-efficiency switching element in DC-DC converters, motor drive half-bridges, and industrial power supplies.
For engineers reviewing the IRLR120NTRLPBF datasheet, IRLR120NTRLPBF pinout, IRLR120NTRLPBF application, or IRLR120NTRLPBF equivalent, key selection criteria include its 100V VDS, 0.185Ω on-resistance at 10V gate drive, 35A pulsed drain capability, fast 4ns turn-on delay, and D-Pak thermal performance with RθJC = 3.1°C/W.
Technical Context
This HEXFET® device uses advanced planar process technology to achieve low gate charge (Qg = 20nC) and low Miller capacitance (Crss = 50pF), enabling high-frequency switching up to several hundred kHz. Its body diode exhibits trr = 110–160ns and Qrr = 410–620nC under defined conditions.
The MOSFET is fully rated for unclamped inductive switching (UIS) with EAS = 85mJ and supports repetitive avalanche (EAR = 4.8mJ). Thermal design is enabled by validated junction-to-case resistance of 3.1°C/W and PCB-mount junction-to-ambient rating of 50°C/W on 1"² FR-4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100V - maximum blocking voltage for 24V/48V bus-level switching applications |
| RDS(on) | 0.185Ω @ VGS = 10V - enables ≤1.1W conduction loss at 10A continuous current |
| ID (TC = 25°C) | 10A - continuous drain current rating under heatsink-cooled conditions |
| Qg | 20nC - total gate charge determines driver strength requirement for <100ns switching transitions |
| td(on) | 4.0ns - short turn-on delay supports high-frequency PWM control in SMPS |
| EAS | 85mJ - single-pulse avalanche energy rating ensures robustness against inductive kickback |
| RθJC | 3.1°C/W - enables direct heatsinking via exposed drain pad for thermal management |
Pinout & Package
IRLR120NTRLPBF is housed in a surface-mount D-Pak (TO-252) package with an exposed drain pad for thermal and electrical connection. The package features gull-wing leads compatible with standard reflow soldering profiles (peak 300°C for 10s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal (S) | Reference node for gate drive; connects to low-side return path and PCB ground plane |
| Pin 2 (Gate) | Control input (G) | High-impedance MOSFET gate requiring <20nC charge for full enhancement |
| Pin 3 (Drain) | Power output (D) | Exposed metal pad - electrically and thermally connected to internal drain; must be soldered to large copper area |
Key Features
| Feature | Design Value |
|---|---|
| Fully avalanche-rated | 85mJ single-pulse energy handling without degradation - eliminates need for external snubbers in inductive loads |
| Low RDS(on) at 10V | 0.185Ω enables >95% efficiency in 12V–48V buck converters at 6–10A load |
| Fast switching | 4ns turn-on delay + 22ns fall time supports >500kHz operation with minimal switching loss |
| Lead-free and RoHS-compliant | Meets consumer-level Pb-free qualification - suitable for global commercial and industrial shipments |
| Enhanced body diode | 110–160ns reverse recovery time and 410–620nC Qrr reduce shoot-through risk in synchronous rectification |
Applications
| Motor Drive Half-Bridge | DC-DC Synchronous Buck Converter |
|---|---|
Use Scenario: Driving brushed DC motors in industrial actuators with PWM frequencies up to 20kHz. IC Role / Device Role / Timing Role: Low-side switch in half-bridge topology; handles bidirectional current during PWM commutation. Use Value: 0.185Ω RDS(on) limits conduction loss to <1.8W at 10A, while 35A pulsed rating accommodates motor startup surges. | Use Scenario: High-efficiency 24V-to-5V/12V point-of-load conversion in telecom power systems. IC Role / Device Role / Timing Role: Synchronous rectifier in buck converter secondary side; replaces Schottky diode to reduce forward drop. Use Value: Body diode VSD = 1.3V at 6A and Qrr = 410–620nC enable lower loss than discrete diodes at 300–500kHz switching. |
| Industrial Power Supply Switch | Overcurrent Protection Circuit |
Use Scenario: Primary-side switching in 100W offline flyback or forward converters with universal AC input. IC Role / Device Role / Timing Role: Main power switch operating in discontinuous conduction mode (DCM) at 65–100kHz. Use Value: 100V VDS withstands reflected transients up to 85V; 85mJ EAS prevents failure during output short-circuit events. | Use Scenario: Solid-state replacement for electromechanical circuit breakers in battery management systems. IC Role / Device Role / Timing Role: Current-controlled load switch with fast turn-off (<30ns effective) for fault isolation. Use Value: 23ns turn-off delay + 22ns fall time ensures sub-100ns response to overcurrent detection signals. |
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 |
|---|---|---|---|
| IRLR7843PBF | VDS = 30V, RDS(on) = 0.0055Ω @ 10V, Qg = 32nC | Optimized for low-voltage (<12V) high-current applications; unsuitable for 48V bus | Select only when VDS stress is <35V and RDS(on) priority outweighs switching speed |
| STP10NK100ZFP | VDS = 100V, RDS(on) = 0.75Ω @ 10V, Qg = 35nC, TO-220FP package | Higher on-resistance and slower switching; requires through-hole mounting and larger heatsink | Use only if D-Pak footprint is unavailable and thermal margin allows higher conduction loss |
Compared with IRLR7843PBF and STP10NK100ZFP, IRLR120NTRLPBF uniquely balances 100V rating, 0.185Ω on-resistance, D-Pak surface-mount compatibility, and 20nC gate charge - making it optimal for space-constrained 24–48V industrial switchers where thermal density and layout simplicity matter.

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The IRLR120NTRLPBF supports 7.0A continuous drain current at TC = 100°C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limits of the D-Pak package and must be verified against actual PCB copper area and ambient conditions using RθJA = 50°C/W (1"² FR-4) or RθJC = 3.1°C/W for heatsink-mounted designs.
Is the body diode suitable for synchronous rectification?
Yes - the integrated body diode has VSD = 1.3V at 6A and trr = 110–160ns, with Qrr = 410–620nC. These values support synchronous rectification in buck converters up to ~500kHz, though external Schottky diodes may still be preferred for ultra-low forward drop in <5V outputs.
Does this MOSFET require a gate resistor for stability?
A gate resistor (typically 10–25Ω) is recommended to dampen ringing caused by gate-drain capacitance (Crss = 50pF) and PCB inductance. Test data shows td(on) and td(off) measured with RG = 11Ω; omitting it risks oscillation and increased switching loss, especially at >200kHz.
Can IRLR120NTRLPBF replace IRLR120NPbF in existing designs?
Yes - IRLR120NTRLPBF is the tape-and-reel (3000-unit) version of the same D-Pak MOSFET as IRLR120NPbF (tube-packaged). Both share identical electrical specs, thermal characteristics, pinout, and RoHS/lead-free compliance; only packaging and reel orientation differ (left vs. right tape feed).
