Product details
Overview
IRFP048N from Infineon Technologies (formerly International Rectifier) is an N-channel enhancement-mode power MOSFET in TO-247AC package, rated for 55 V VDS, 68 A ID (TC = 25°C), and 180 W PD. It features RDS(on) ≤ 12.5 mΩ at VGS = 10 V and is used in DC-DC converters, motor drives, and uninterruptible power supplies.
For engineers reviewing the IRFP048N datasheet, IRFP048N pinout, IRFP048N application, or IRFP048N equivalent, key selection criteria include on-resistance at 10 V gate drive, safe operating area under repetitive avalanche conditions, thermal resistance from junction to case, and gate charge for high-frequency switching efficiency.
Technical Context
This MOSFET employs planar stripe cell structure with optimized gate oxide thickness and doped polysilicon gate for low RDS(on) and controlled Qg. Its body diode exhibits trr = 120 ns and Qrr = 190 nC at IF = 34 A, enabling hard-switched flyback and synchronous rectification.
The device supports continuous drain current up to 68 A at TC = 25°C and derates linearly to 34 A at TC = 100°C. It is characterized for unclamped inductive switching (UIS) with EAS = 420 mJ at TJ = 25°C, confirming ruggedness in motor control transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 55 V - Maximum blocking voltage in off-state; defines maximum bus voltage in buck or half-bridge topologies |
| RDS(on) max | 12.5 mΩ at VGS = 10 V - Directly impacts conduction loss in high-current 12 V/24 V systems |
| ID (continuous) | 68 A at TC = 25°C - Supports >50 A load current with adequate heatsinking in industrial SMPS |
| Qg | 120 nC - Determines gate driver power requirement and switching transition time at 100 kHz–500 kHz |
| trr | 120 ns - Limits reverse recovery loss in freewheeling paths; enables operation without external snubbers |
| EAS | 420 mJ - Specifies single-pulse avalanche energy handling; critical for motor phase-leg short-circuit robustness |
Pinout & Package
IRFP048N uses the TO-247AC package: three-terminal through-hole outline with isolated tab (drain-connected), standard lead spacing, and 1.0 mm lead diameter. Thermal resistance RθJC = 0.85°C/W enables direct mounting to heatsinks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current return path to high-side switch node or ground reference | Electrically connected to metal tab; requires insulating washer when mounted to grounded heatsink |
| Gate | Control terminal for channel inversion and conduction initiation | High-impedance input requiring <120 nC total charge for full turn-on; sensitive to ESD |
| Source | Reference node for gate drive and current sensing | Common connection point for shunt resistor, gate driver return, and controller ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) at 10 V drive | Enables <1.5 W conduction loss at 30 A DC in 12 V battery-powered inverters |
| Fast body diode recovery | Reduces switching loss by 30% vs. legacy MOSFETs in non-synchronous buck converters |
| 100% UIS tested | Guarantees survival under worst-case inductive turn-off without external clamping |
| Lead-free (PbF) construction | Complies with RoHS Directive 2011/65/EU; no exemption required for solderability or reliability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP55NF06L | RDS(on) = 14 mΩ at VGS = 10 V; lower VDS (60 V) but higher Qg (145 nC) | Suitable for 24 V systems only; less efficient above 40 kHz due to gate charge | Prefer for cost-sensitive 24 V motor control where switching frequency ≤20 kHz |
| IXTH50N50L2 | VDS = 500 V; RDS(on) = 100 mΩ; higher voltage rating sacrifices on-resistance | Used in 400 V DC link inverters, not 12–48 V low-voltage systems | Select only when 55 V rating is insufficient and system requires ≥400 V blocking capability |
Compared with STP55NF06L and IXTH50N50L2, IRFP048N delivers optimal balance of low conduction loss, manageable gate drive demand, and proven ruggedness in 12–48 V industrial power stages-making it the preferred choice for high-reliability mid-power switching where both efficiency and transient robustness matter.

FAQ
Is IRFP048N logic-level compatible?
No. IRFP048N requires ≥10 V gate drive for full enhancement and specified RDS(on); it is not guaranteed to operate reliably below 4.5 V. For 3.3 V or 5 V microcontroller-driven applications, a gate driver IC such as TC4427 or IR2104 is mandatory to achieve low on-resistance and fast switching.
What is the maximum allowable junction temperature?
The absolute maximum junction temperature is 175°C. Derating curves in the official datasheet show that continuous drain current drops to 34 A at TC = 100°C, implying a practical thermal design limit of ≤150°C junction temperature for long-term reliability in sealed enclosures with limited airflow.
Does IRFP048N have integrated ESD protection?
No. The device has no built-in gate protection diodes. Gate-source voltage must be limited to ±20 V, and handling requires strict ESD controls-grounded wrist straps, conductive foam, and ionized air workstations-to prevent latent damage from static discharges exceeding 1000 V HBM.
Can IRFP048N replace IRFP250N in existing designs?
Yes, with verification. IRFP048N offers lower RDS(on) (12.5 mΩ vs. 45 mΩ), faster trr (120 ns vs. 220 ns), and identical TO-247AC footprint and pinout. Layout changes are unnecessary, but gate drive strength and PCB thermal relief should be rechecked due to higher peak current capability.
