Product details
Overview
IRFR120NTRLPBF from Infineon Technologies (formerly International Rectifier) is a 100 V, 7.5 A N-channel enhancement-mode MOSFET in DPAK (TO-252) package, optimized for high-efficiency DC-DC converters and motor control switches. It features 0.27 Ω RDS(on) at VGS = 10 V, 45 nC total gate charge, and 100% avalanche-rated ruggedness for reliable operation in inductive load switching.
For engineers reviewing the IRFR120NTRLPBF datasheet, IRFR120NTRLPBF pinout, IRFR120NTRLPBF application, or IRFR120NTRLPBF equivalent, key selection criteria include RDS(on) vs. thermal resistance, gate charge for PWM switching loss trade-offs, and SOA compliance under repetitive unclamped inductive switching conditions.
Technical Context
This MOSFET employs planar stripe cell technology with optimized channel density to achieve low on-resistance while maintaining fast turn-on/turn-off times. Its 100 V VDSS rating supports 48 V bus systems, and the 7.5 A ID rating is specified at TC = 25 °C with derating above 25 °C.
The device uses a standard logic-level gate drive compatible with 5 V microcontrollers, and its 45 nC Qg enables efficient operation at 100–500 kHz switching frequencies in synchronous buck topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 100 V - Supports 48 V nominal input systems with 2× safety margin against transients |
| RDS(on) @ VGS = 10 V | 0.27 Ω - Enables ≤2.0 W conduction loss at 7.5 A continuous drain current |
| ID (continuous) | 7.5 A @ TC = 25 °C - Requires heatsinking above ambient for sustained full-load operation |
| Qg | 45 nC - Determines gate driver power requirement and switching loss in hard-switched PWM |
| EAS | 190 mJ - Confirmed single-pulse avalanche energy rating for inductive load snubbing |
| RθJC | 3.5 °C/W - Defines junction-to-case thermal path for PCB copper pour design |
Pinout & Package
DPAK (TO-252) surface-mount package with exposed drain pad for thermal and electrical connection. Standard 3-pin configuration: Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Gate (G) | Control terminal | Receives voltage-controlled signal to modulate channel conductivity; requires <1 μA bias current |
| Drain (D) | High-side power output | Connected to load or supply rail; electrically and thermally tied to exposed metal tab |
| Source (S) | Reference node | Serves as return path for load current and reference for gate drive; common node in low-side switch configuration |

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 |
|---|---|---|---|
| STP12NF10 | RDS(on) = 0.22 Ω, Qg = 32 nC, TO-220 package | Higher thermal mass but no surface-mount compatibility; lower gate charge reduces driver stress | Prefer for prototyping or through-hole designs where board space is not constrained |
| IXTP12N10P | RDS(on) = 0.25 Ω, Qg = 40 nC, TO-220FP package | Shorter lead time availability; same voltage rating but slightly lower RDS(on) | Choose when DPAK footprint is not required and vertical mounting is acceptable |
Compared with STP12NF10 and IXTP12N10P, IRFR120NTRLPBF offers superior surface-mount thermal performance via its DPAK drain tab, enabling higher power density in compact DC-DC modules without sacrificing avalanche ruggedness.

FAQ
What is the maximum continuous drain current rating for IRFR120NTRLPBF?
The IRFR120NTRLPBF is rated for 7.5 A continuous drain current at case temperature TC = 25 °C. This rating decreases linearly with increasing case temperature, reaching approximately 4.5 A at TC = 100 °C, based on the device's 3.5 °C/W thermal resistance and safe operating area limits.
Does IRFR120NTRLPBF require a gate resistor for typical PWM switching?
Yes - a 10–22 Ω series gate resistor is recommended to dampen ringing and limit peak gate current during 10–500 kHz switching. With 45 nC total gate charge and typical 12 V gate drive, peak current exceeds 1 A without limiting, risking gate oxide stress and EMI generation in high-speed layouts.
Can IRFR120NTRLPBF be used in linear mode for analog current regulation?
Yes - it is qualified for linear-mode operation with defined Safe Operating Area (SOA) curves up to 100 V × 1 A DC. For constant-current LED drivers, operation must remain within the SOA boundary at the target junction temperature, typically requiring active heatsinking above 500 mA.
Is the exposed drain pad on the DPAK package electrically connected to the drain terminal?
Yes - the large exposed metal pad on the underside of the DPAK package is internally bonded to the drain terminal and must be soldered to a PCB copper pour for both electrical continuity and thermal dissipation. Thermal vias beneath the pad are strongly recommended to transfer heat to inner ground planes.
