Product details
Overview
IRF1405LPBF from Infineon Technologies is a 55 V, 131 A N-channel HEXFET® Power MOSFET in TO-262 (ISOTOP) package, featuring 4.6 mΩ typical RDS(on) at VGS = 10 V, 175°C maximum junction temperature, and 590 mJ single-pulse avalanche energy. It serves as a high-current main switch in DC-DC synchronous rectifiers and motor phase-legs.
For engineers reviewing the IRF1405LPBF datasheet, IRF1405LPBF pinout, IRF1405LPBF application, or IRF1405LPBF equivalent, key selection criteria include its 5.3 mΩ max RDS(on), 680 A pulsed drain current capability, fast 190 ns rise time, and robust 175°C thermal rating for industrial power stage design.
Technical Context
This planar stripe HEXFET device uses advanced silicon processing to minimize conduction loss while maintaining high dv/dt immunity (5.0 V/ns) and fast switching (13 ns turn-on delay, 110 ns fall time). Its body diode exhibits 1.3 V forward voltage at 101 A and 88–130 ns reverse recovery time.
The MOSFET supports repetitive avalanche operation up to Tjmax, enabled by validated thermal response curves and 0.75°C/W junction-to-case thermal resistance. Gate charge parameters (170–260 nC total, 62–93 nC Miller charge) are optimized for gate driver compatibility in hard-switched topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 55 V - Maximum blocking voltage in off-state; defines upper limit for bus voltage in 48 V systems. |
| RDS(on) max | 5.3 mΩ @ VGS = 10 V, ID = 101 A - Directly determines conduction loss (Pcond ≈ I² × 5.3 mΩ) in continuous high-current operation. |
| ID @ TC = 25°C | 131 A - Continuous current rating under ideal heatsink conditions; sets PCB copper and thermal interface requirements. |
| EAS | 590 mJ - Single-pulse avalanche energy handling capacity; enables reliable unclamped inductive switching in motor drives. |
| tr / tf | 190 ns / 110 ns @ VDD = 38 V, ID = 110 A - Defines minimum achievable switching period and associated switching loss in PWM converters. |
| RθJC | 0.75°C/W - Junction-to-case thermal resistance; allows direct calculation of die temperature rise above heatsink temperature. |
| Qg max | 260 nC - Total gate charge; determines required gate driver peak current (Idrive ≥ Qg/trise) for target switching speed. |
Pinout & Package
IRF1405LPBF is housed in a TO-262 (ISOTOP) package with isolated tab, designed for surface-mount or through-hole mounting on thermally enhanced PCBs. The case is electrically connected to the Drain terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main high-side current path | Electrically tied to metal tab; requires insulated mounting hardware when referenced to non-ground potentials. |
| Source | Return path for load current | Low-inductance connection point for source loop; critical for minimizing switching oscillation and EMI. |
| Gate | Control input for channel conduction | High-impedance node requiring low-impedance gate driver and RC snubber to suppress ringing during fast transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) | 4.6 mΩ typ. at 10 V drive - Reduces conduction loss by >30% vs. legacy 55 V MOSFETs in 100 A applications. |
| 175°C rated junction | Extended thermal margin - Enables operation in sealed enclosures or high ambient environments without derating. |
| Repetitive avalanche rated | Validated up to Tjmax - Eliminates need for external clamping in inductive load commutation (e.g., BLDC motor phases). |
| Fast body diode | trr = 88–130 ns, Qrr = 250–380 nC - Minimizes reverse recovery loss and shoot-through risk in synchronous rectification. |
| Dynamic dv/dt rating | 5.0 V/ns - Ensures noise immunity against parasitic turn-on during high-speed switching in high-di/dt circuits. |
Applications
| Industrial Motor Drive | DC-DC Synchronous Rectifier |

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 |
|---|---|---|---|
| STP130N5F6 | RDS(on) = 4.2 mΩ min, 5.0 mΩ max; 175°C rating; TO-220FP package | Lower RDS(on) but higher RθJA (62°C/W); no isolated tab | Select for cost-sensitive designs where heatsink isolation is not required and board space permits TO-220 footprint. |
| IXTH120N50L2 | RDS(on) = 5.5 mΩ max; 500 V VDSS; TO-247 package; 150°C Tj | Higher voltage rating but lower thermal capability and slower switching (tr = 250 ns) | Choose only if 500 V blocking is mandatory and 175°C operation is not needed; avoid for 48 V systems due to over-spec. |
Compared with STP130N5F6 and IXTH120N50L2, IRF1405LPBF offers superior thermal performance (0.75°C/W vs. ≥1.2°C/W), verified repetitive avalanche capability, and TO-262 isolation-making it optimal for compact, high-reliability industrial inverters where heatsink grounding constraints exist.

FAQ
Is IRF1405LPBF RoHS-compliant and lead-free?
Yes, IRF1405LPBF is RoHS-compliant and lead-free, as indicated by the "PbF" suffix in its part number and confirmed in Infineon's official compliance documentation. It meets EU Directive 2011/65/EU and JEDEC J-STD-609A Class 3 moisture sensitivity level.
What is the recommended gate resistor value for 100 kHz switching?
For 100 kHz operation with minimal overshoot, a 10 Ω series gate resistor is recommended based on gate charge (260 nC max) and typical driver output impedance. This balances switching speed (≈100 ns effective rise/fall) against ringing and EMI, especially with 1.1 Ω test condition reference data.
Can IRF1405LPBF replace IRF1404 in existing designs?
Yes, IRF1405LPBF is a direct upgrade to IRF1404: both share TO-262 package, 55 V rating, and pinout. However, IRF1405LPBF offers 15% lower RDS(on) (5.3 mΩ vs. 6.0 mΩ), higher ID (131 A vs. 120 A), and improved avalanche energy (590 mJ vs. 470 mJ), enabling higher efficiency and reliability without layout changes.
Does the TO-262 package require thermal compound when mounted to a heatsink?
Yes, thermal compound (e.g., silicone-based grease or phase-change pad) is required between the IRF1405LPBF's isolated metal tab and heatsink to minimize interfacial thermal resistance. Mounting torque must be controlled to 1.1 N·m (10 lbf·in) to ensure uniform pressure without damaging the package seal.
