Product details
Overview
IRFR2405PBF from Infineon Technologies (formerly International Rectifier) is a 55 V, 56 A N-channel enhancement-mode power MOSFET in D-Pak surface-mount package, featuring 11.8 mΩ typical RDS(on) at VGS = 10 V, fully avalanche-rated, and optimized for high-efficiency DC-DC converters and motor control in industrial power supplies.
For engineers reviewing the IRFR2405PBF datasheet, IRFR2405PBF pinout, IRFR2405PBF application, or IRFR2405PBF equivalent, key selection criteria include its 130 mJ single-pulse avalanche energy, 5.0 V/ns diode recovery dv/dt rating, 70 nC total gate charge, and thermal resistance of 1.4 °C/W junction-to-case - critical for thermally constrained PCB layouts and unclamped inductive switching.
Technical Context
This seventh-generation HEXFET device uses advanced silicon processing to achieve low on-resistance per die area while maintaining ruggedness under repetitive avalanche stress. Its body diode exhibits 62 ns typical reverse recovery time and 170 nC reverse recovery charge at IF = 34 A and di/dt = 100 A/µs.
The MOSFET supports fast switching with 15 ns turn-on delay, 130 ns rise time, and 78 ns fall time under standard test conditions (VDD = 28 V, ID = 34 A, RG = 6.8 Ω), enabled by low input capacitance (2430 pF) and Miller charge (19 nC).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 55 V - maximum blocking voltage before avalanche; sets upper limit for bus voltage in buck converters and half-bridge topologies |
| RDS(on) @ 10 V | 0.0118 Ω typ - enables ≤0.4 W conduction loss at 6 A continuous drain current in compact SMT designs |
| ID @ TC = 25°C | 56 A - continuous current capability when mounted on heatsinked PCB; limited to 40 A at 100°C case temperature |
| EAS | 130 mJ - single-pulse avalanche energy rating allows safe operation during inductive load turn-off without external snubbers |
| Qg | 70 nC - total gate charge determines driver strength requirement; compatible with standard 1-A peak gate drivers |
| dv/dt Rating | 5.0 V/ns - ensures robustness against parasitic turn-on during high-speed switching in noisy power stages |
| RθJC | 1.4 °C/W - enables direct thermal path to copper pour or heatsink; supports >80 W power dissipation with proper mounting |
Pinout & Package
D-Pak (TO-252AA) surface-mount package with exposed drain pad for thermal and electrical connection; three terminals: Drain (D), Source (S), Gate (G).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (D) | Main current-carrying terminal, tied to internal die substrate | Electrically and thermally connected to large exposed copper pad; must be routed to high-current paths and thermal plane |
| Source (S) | Reference node for gate drive and current return path | Connected to source bond wires and internal source metallization; forms low-inductance loop with gate driver ground |
| Gate (G) | Control electrode for channel formation | High-impedance input requiring <200 nA leakage at ±20 V; sensitive to ESD and requires series resistor for ringing suppression |
Key Features
| Feature | Design Value |
|---|---|
| Fully avalanche rated | Guarantees survivability under unclamped inductive switching up to 130 mJ single-pulse and 11 mJ repetitive energy |
| Low RDS(on) × Qg figure-of-merit | 0.83 Ω·nC - balances conduction and switching losses for high-frequency (>100 kHz) SMPS designs |
| Fast body diode recovery | 62 ns trr and 170 nC Qrr - reduces cross-conduction loss and EMI in synchronous rectification and H-bridge motor drives |
| Lead-free and RoHS compliant | Meets JEDEC J-STD-020 reflow profile; compatible with vapor phase, infrared, and wave soldering processes |
| Thermally enhanced D-Pak | 1.4 °C/W RθJC - enables >50 W continuous power dissipation with minimal PCB copper area versus standard SO-8 |

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 |
|---|---|---|---|
| STP55NF06L | 60 V VDSS, 50 A ID, 0.014 Ω RDS(on), TO-220 package | Through-hole mounting only; higher RθJA (62 °C/W) limits power density | Preferred where mechanical robustness and manual assembly outweigh SMT density requirements |
| IXTP50N055T | 55 V VDSS, 50 A ID, 0.012 Ω RDS(on), TO-220AB package | No avalanche rating specified; lacks EAS specification and dv/dt immunity data | Suitable for non-inductive or snubber-protected circuits where cost is primary constraint |
Compared with STP55NF06L and IXTP50N055T, IRFR2405PBF offers superior thermal performance in surface-mount form factor, guaranteed avalanche ruggedness, and faster body diode recovery - making it optimal for high-reliability, space-constrained, and inductive-load applications.

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The IRFR2405PBF supports 40 A continuous drain current at TC = 100°C with VGS = 10 V, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the D-Pak package and requires adequate PCB copper area or heatsinking to maintain junction temperature below 175°C.
Is the body diode suitable for synchronous rectification?
Yes - the integrated body diode has 62 ns typical reverse recovery time and 170 nC Qrr at IF = 34 A, enabling use in synchronous rectifier configurations up to ~200 kHz. However, external Schottky diodes remain preferred for ultra-low forward drop in high-efficiency designs.
Does IRFR2405PBF require a gate resistor for stability?
Yes - a 5–10 Ω series gate resistor is recommended to dampen ringing caused by gate loop inductance and Miller capacitance interaction. This improves switching waveform integrity and reduces EMI, especially in high-di/dt applications like motor drives and inverters.
Can IRFR2405PBF replace IRFR2405 without design changes?
Yes - IRFR2405PBF is the lead-free, RoHS-compliant version of IRFR2405, with identical electrical specifications, pinout, and package dimensions. The "PbF" suffix denotes lead-free termination; no layout or thermal redesign is required for drop-in replacement in new production.
