Product details
Overview
IRF7401TRPBF from Infineon Technologies (formerly International Rectifier) is a dual N-channel MOSFET in SO-8 package, optimized for high-efficiency DC-DC conversion and load switching. It features RDS(on) = 0.022 Ω @ VGS = 4.5 V, 6.9 A continuous drain current, and 30 V drain-source voltage rating - enabling use in synchronous buck converters and battery protection circuits.
For engineers reviewing the IRF7401TRPBF datasheet, IRF7401TRPBF pinout, IRF7401TRPBF application, or IRF7401TRPBF equivalent, key selection criteria include gate threshold voltage (1.5 V min), low gate charge (17 nC), body diode reverse recovery time (45 ns), and thermal resistance (RθJA = 62 °C/W).
Technical Context
This dual N-channel device integrates two matched MOSFETs in a single SO-8 package with shared source terminals - configured as a common-source pair ideal for synchronous rectification. Its logic-level gate drive (VGS(th) = 1.5–2.5 V) enables direct interfacing with 3.3 V and 5 V controllers without level-shifting.
The device uses TrenchMOS technology to achieve low RDS(on) and fast switching (td(on) = 12 ns, tf = 15 ns), while its integrated body diodes support bidirectional current flow in half-bridge topologies and provide controlled reverse recovery (Qrr = 23 nC).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - supports 24 V rail systems with margin for transients |
| RDS(on) @ 4.5 V | 0.022 Ω - enables <1 W conduction loss at 6.9 A in compact layouts |
| ID (continuous) | 6.9 A - rated for sustained operation at TC = 100 °C |
| QG | 17 nC - reduces gate driver power demand and switching losses |
| VGS(th) | 1.5–2.5 V - ensures full enhancement with standard logic-level PWM signals |
| tr/tf | 10/15 ns - minimizes overlap loss in high-frequency (>500 kHz) converters |
| RθJA | 62 °C/W - defines thermal derating on standard 1-oz FR4 PCB with 1-in² copper pour |
Pinout & Package
SO-8 surface-mount package per JEDEC MS-012AA, 4.9 × 6.0 mm footprint, 1.27 mm lead pitch, gull-wing leads. Thermal pad not present; power dissipation relies on copper area under drain pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Drain (Channel 1) | High-current output node; electrically tied to exposed drain tab (pins 1–4) |
| 5 | Gate (Channel 1) | Control input for first MOSFET; requires <17 nC charge for full turn-on |
| 6, 7, 8 | Source (Common) | Shared source node for both channels; return path for load current |
| - | Drain (Channel 2) | Not separately accessible - second channel shares drain pins 1–4 and source pins 6–8 |
Key Features
| Feature | Design Value |
|---|---|
| Dual N-channel configuration | Single-package synchronous rectifier pair eliminates layout mismatch and timing skew |
| Logic-level gate drive | Operates fully enhanced down to 3.3 V supply - compatible with microcontroller GPIOs |
| Low QGD/QG ratio | 0.41 - improves Miller immunity and reduces risk of shoot-through in half-bridge |
| Fast body diode recovery | trr = 45 ns, Qrr = 23 nC - limits voltage spikes and EMI during freewheeling |
| Lead-free and RoHS compliant | Meets IPC-J-STD-020 moisture sensitivity level 1 - no bake required before reflow |
Applications
| DC-DC Synchronous Buck Converter | USB-C Power Delivery Switch |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si7852DP-T1-GE3 | RDS(on) = 0.018 Ω @ 4.5 V; higher QG = 22 nC; same SO-8 package | Better conduction loss but slower switching; less suitable above 1 MHz | Prefer for <500 kHz high-current apps where thermal margin dominates switching loss |
| DMN3022LSD-13 | RDS(on) = 0.025 Ω @ 4.5 V; lower QG = 12 nC; dual N-channel with independent sources | Independent source pins enable asymmetric configurations (e.g., OR-ing); no shared-source constraint | Choose when gate drive isolation or non-synchronous control of each channel is required |
Compared with Si7852DP-T1-GE3 and DMN3022LSD-13, IRF7401TRPBF offers the best balance of low RDS(on), moderate gate charge, and shared-source simplicity - making it optimal for cost-sensitive, space-constrained synchronous rectifiers where layout symmetry matters.

FAQ
What is the maximum safe operating junction temperature for IRF7401TRPBF?
The absolute maximum junction temperature is 150 °C per datasheet. Derating begins at TJ > 125 °C, and continuous operation above 150 °C risks irreversible parametric shift or bond-wire failure. Thermal design must ensure TJ ≤ 150 °C under worst-case ambient and power dissipation conditions.
Can IRF7401TRPBF be used in a half-bridge configuration?
Yes - its dual N-channel structure with shared source enables half-bridge use, but external high-side gate driving (e.g., bootstrap or isolated supply) is required since no integrated level shifter exists. The low QG and fast tf support reliable commutation up to 1 MHz with proper dead-time control.
Does IRF7401TRPBF have avalanche rating?
Yes - it is 100% avalanche tested per EAS = 31 mJ at TJ = 25 °C. This rating applies to single-pulse inductive switching events only; repetitive avalanche is not guaranteed and may degrade reliability over time.
Is the SO-8 package thermally enhanced?
No - IRF7401TRPBF uses a standard SO-8 outline without an exposed thermal pad. Heat transfer occurs through leads and PCB copper; thermal performance depends entirely on board layout - minimum 1-in² 2-oz copper pour under drain pins is recommended for full 6.9 A rating.
