Product details
Overview
IRLR120NPBF from Infineon Technologies is a 100V, 10A N-channel enhancement-mode power MOSFET in D-Pak (TO-252) package, featuring RDS(on) = 0.185Ω at VGS = 10V, fully avalanche-rated, and lead-free. It serves as a high-efficiency switching element in DC-DC converters, motor drivers, and load-switching circuits operating up to 175°C junction temperature.
For engineers reviewing the IRLR120NPBF datasheet, IRLR120NPBF pinout, IRLR120NPBF application, or IRLR120NPBF 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 conduction loss and robust unclamped inductive switching (UIS) performance. Its gate threshold voltage (1.0–2.0V) supports logic-level drive, while the 20nC total gate charge enables efficient high-frequency switching above 100kHz.
The integrated body diode exhibits 1.3V forward voltage at 6A and 110–160ns reverse recovery time, making it suitable for synchronous rectification and freewheeling in buck converters. Thermal design is enabled by validated junction-to-case resistance of 3.1°C/W under PCB-mount conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100V - Maximum blocking voltage for 24V/48V industrial bus and automotive battery-connected loads |
| RDS(on) | 0.185Ω @ VGS = 10V - Enables ≤1.1W conduction loss at 10A continuous current |
| ID | 10A @ TC = 25°C - Continuous current rating with standard heatsinking on FR-4 PCB |
| EAS | 85mJ - Single-pulse avalanche energy tolerance supports reliable operation during inductive load switching |
| Qg | 20nC - Total gate charge determines required driver peak current for <100ns switching transitions |
| RθJC | 3.1°C/W - Junction-to-case thermal resistance enables direct heatsink mounting for high-power density designs |
| td(on) | 4.0ns - Turn-on delay time defines minimum controllable pulse width in PWM applications |
Pinout & Package
IRLR120NPBF is housed in a surface-mount D-Pak (TO-252) package with exposed drain pad for thermal and electrical connection. The three terminals are arranged in a straight-lead configuration compatible with automated pick-and-place and reflow soldering.
| 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 control node requiring <20nC charge for full enhancement |
| Pin 3 (Drain) | Power output (D) | Exposed copper pad - electrically and thermally connected to internal drain structure; must be routed to high-current traces and/or heatsink |
Key Features
| Feature | Design Value |
|---|---|
| Fully avalanche-rated | 85mJ single-pulse energy withstand without failure - eliminates need for external snubbers in inductive switching |
| Logic-level gate drive | VGS(th) = 1.0–2.0V - compatible with 3.3V/5V microcontrollers and gate drivers without level-shifting |
| Low RDS(on) | 0.185Ω @ 10V - reduces conduction losses by >30% vs. legacy 100V MOSFETs in same package |
| Lead-free and RoHS-compliant | Pb-free plating and assembly - meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1) for unlimited floor life |
| Fast switching | 4ns td(on), 22ns tf - supports >500kHz SMPS operation with minimal switching loss |

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 |
|---|---|---|---|
| STP10NK100ZFP | 100V, 10A, RDS(on) = 0.36Ω, TO-220FP package, Zener-protected gate | Higher on-resistance and through-hole mounting - less suitable for high-density SMT designs | Preferred where gate protection against overvoltage is critical and thermal mass from TO-220 is acceptable |
| IXTP10N100D2 | 100V, 10A, RDS(on) = 0.28Ω, TO-220 package, ultra-low Qg = 12nC | Lower gate charge but higher RDS(on) and larger footprint - better for very high-frequency switching with moderate current | Chosen when switching frequency exceeds 1MHz and gate drive strength is limited |
Compared with STP10NK100ZFP and IXTP10N100D2, IRLR120NPBF offers the lowest RDS(on) in surface-mount form factor, optimal for space-constrained 10A DC-DC and motor control where thermal resistance and layout density are prioritized over gate protection or extreme-frequency operation.

FAQ
Is IRLR120NPBF suitable for 5V microcontroller gate drive?
Yes. With a gate threshold voltage range of 1.0–2.0V and full enhancement achievable at VGS = 5V (RDS(on) = 0.265Ω), it interfaces directly with 5V logic without external level shifters. Gate charge remains low at 20nC, enabling clean switching with typical MCU GPIO drive capability.
What is the maximum continuous current at 85°C case temperature?
Per the derating curve in the datasheet, continuous drain current drops linearly from 10A at 25°C to approximately 7.0A at 100°C case temperature. At 85°C case temperature, the rated continuous current is ~7.8A, assuming adequate PCB copper area per AN-994 layout guidelines.
Does IRLR120NPBF have integrated gate protection?
No. IRLR120NPBF does not include integrated gate Zener clamping or ESD protection diodes. External gate resistors (typically 10–47Ω) and TVS diodes are recommended for robustness in noisy environments or high-dV/dt applications such as motor drives.
Can IRLR120NPBF replace IRLU120NPBF in a design?
Yes, with mechanical consideration. Both share identical electrical specs, but IRLR120NPBF uses D-Pak (TO-252) surface-mount packaging while IRLU120NPBF uses I-Pak (TO-220AB) through-hole. Replacement requires PCB footprint change and thermal interface redesign, though thermal performance favors D-Pak due to lower RθJC.
