Product details
Overview
IRFBA1404P from Infineon Technologies (formerly International Rectifier) is an N-channel enhancement-mode power MOSFET in TO-247 package, rated for 400 V VDS, 14 A ID (TC = 100°C), and 0.4 Ω RDS(on) max at VGS = 10 V. It serves as a high-voltage switching element in offline SMPS primary-side circuits, PFC stages, and industrial motor drives.
For engineers reviewing the IRFBA1404P datasheet, IRFBA1404P pinout, IRFBA1404P application, or IRFBA1404P equivalent, key selection criteria include its 400 V blocking voltage, 0.4 Ω on-resistance at 10 V gate drive, TO-247 thermal performance, and suitability for hard-switched flyback and forward converters operating up to 100 kHz.
Technical Context
This Generation 3 HEXFET device uses planar vertical DMOS structure with optimized cell pitch and gate oxide thickness to balance conduction loss and switching speed. Its threshold voltage (VGS(th)) ranges from 2.0 V to 4.0 V, enabling reliable turn-on with standard 10 V gate drivers while maintaining low leakage at 400 V.
The MOSFET features a fully avalanche-rated design (EAS = 280 mJ at TJ = 25°C), integrated body diode with soft recovery characteristics (trr ≈ 120 ns), and gate charge (Qg) of 42 nC - supporting efficient operation in discontinuous and continuous conduction mode topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 400 V - supports 230 VAC mains-fed designs with ≥2× safety margin against line transients |
| RDS(on) max | 0.4 Ω @ VGS = 10 V - enables <1.96 W conduction loss at 7 A DC load current |
| ID (TC = 100°C) | 14 A - defines maximum continuous drain current under heatsink-limited thermal conditions |
| Qg | 42 nC - determines gate driver power requirement and influences turn-on/turn-off transition times |
| EAS | 280 mJ - ensures single-pulse avalanche ruggedness during overvoltage events without failure |
| trr | 120 ns - limits reverse recovery losses in bridge-leg or synchronous rectifier configurations |
Pinout & Package
Package: TO-247 (3-pin, straight lead, non-isolated). Standard mounting via center tab (drain) to heatsink with insulating washer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path output terminal | Electrically connected to metal tab; requires thermal interface and electrical isolation when mounted |
| Gate | Control electrode | High-impedance input requiring <42 nC charge for full enhancement; sensitive to ESD |
| Source | Reference node for gate drive and current return | Common connection point for load return path and gate driver ground reference |
Key Features
| Feature | Design Value |
|---|---|
| Fully avalanche-rated | 280 mJ single-pulse energy handling ensures robustness against inductive switching surges |
| Low gate charge | 42 nC Qg reduces driver losses and enables use with low-power gate drivers like IR2110 |
| Soft-recovery body diode | 120 ns trr minimizes voltage overshoot and EMI in hard-commutated topologies |
| TO-247 thermal capability | 0.85°C/W RθJC allows 14 A operation at TC = 100°C with adequate heatsinking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP40NF40 | 400 V VDS, 40 A ID, 0.077 Ω RDS(on), higher current rating but larger die size and Qg = 75 nC | Better for high-current, lower-frequency (<50 kHz) applications; less suitable for high-frequency PFC due to gate charge | Select when thermal headroom exists and conduction loss dominates over switching loss |
| IXTH12N40P | 400 V VDS, 12 A ID, 0.45 Ω RDS(on), similar Qg (40 nC), enhanced ruggedness (EAS = 320 mJ) | Preferred for mission-critical industrial inverters where single-pulse avalanche margin is prioritized over RDS(on) | Select when system-level reliability under fault conditions outweighs minor conduction loss penalty |
Compared with STP40NF40 and IXTH12N40P, the IRFBA1404P offers optimal balance of 14 A current capability, 0.4 Ω on-resistance, and 42 nC gate charge for 65–200 kHz high-voltage switching, making it especially suited for space-constrained PFC and SMPS designs where thermal management and driver simplicity are critical.

FAQ
What is the maximum junction temperature for continuous operation?
The IRFBA1404P has a maximum rated junction temperature of 175°C. Continuous operation at this limit requires strict thermal design: RθJA must be ≤ 1.2°C/W with PCB copper area ≥ 10 cm² and forced airflow ≥ 200 LFM, or RθJC ≤ 0.85°C/W with properly torqued heatsink mounting and thermal interface material.
Is a gate resistor required, and what value is recommended?
Yes, a series gate resistor is required to control dV/dt and prevent oscillation. For typical 100–200 kHz operation with a 1 A peak gate driver, a 10 Ω resistor provides optimal trade-off between switching speed (trise ≈ 45 ns) and EMI suppression. Lower values increase ringing risk; higher values degrade efficiency above 150 kHz.
Can IRFBA1404P replace IRFP460 in existing designs?
No - IRFP460 is rated for 500 V and 20 A with 0.27 Ω RDS(on). Substituting IRFBA1404P (400 V, 14 A, 0.4 Ω) risks overvoltage failure in 400 V+ bus applications and increases conduction loss by ~48% at 10 A. Derating analysis and layout review are mandatory before any replacement attempt.
Does this MOSFET require a negative gate turn-off voltage?
No. The IRFBA1404P operates reliably with 0 V to +10 V gate drive. Negative turn-off voltage is unnecessary and not specified in the datasheet; applying −5 V may accelerate gate oxide degradation. Standard TTL/CMOS-compatible drivers with 0 V low-state and 10–15 V high-state are fully sufficient.
