Product details
Overview
IRF7424PBF from Infineon Technologies (formerly International Rectifier) is a P-channel enhancement-mode MOSFET designed for high-efficiency load and battery management switching. It features -30 V VDS, 13.5 mΩ RDS(on) at VGS = -10 V and ID = -11 A, SO-8 package with enhanced thermal leadframe, and operates across -55 °C to +150 °C junction temperature. Used in portable power distribution and USB-C PD load switches.
For engineers reviewing the IRF7424PBF datasheet, IRF7424PBF pinout, IRF7424PBF application, or IRF7424PBF equivalent, key selection criteria include verified RDS(on) at -4.5 V (-22 mΩ), pulsed drain current capability (-47 A), gate charge (75–110 nC), and SO-8 thermal resistance (50 °C/W).
Technical Context
This device employs trench-gate HEXFET architecture optimized for low RDS(on) per die area and fast switching. Its body diode exhibits 40–60 ns reverse recovery time and 47–71 nC Qrr at IF = -2.5 A, supporting synchronous rectification in buck converters.
The SO-8 package uses a customized leadframe to improve thermal conduction and enable multi-die configurations. Gate threshold voltage ranges from -1.0 V to -2.5 V, ensuring reliable turn-on with standard logic-level drive down to -4.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -30 V - Maximum blocking voltage in high-side switch or reverse polarity protection circuits |
| RDS(on) @ VGS = -10 V | 13.5 mΩ - Enables <1.5 W conduction loss at 11 A continuous, critical for thermally constrained PCBs |
| RDS(on) @ VGS = -4.5 V | 22 mΩ - Supports direct interface with 5 V microcontroller GPIO without level-shifting |
| Qg | 75–110 nC - Determines gate driver strength requirement; enables ~100 kHz PWM operation with 1 Ω driver |
| IDM | -47 A - Allows short-circuit robustness and inrush current handling in hot-swap applications |
| RθJA | 50 °C/W - Defines thermal derating on 1-in² copper; requires heatsinking above ~1.6 W dissipation |
Pinout & Package
IRF7424PBF is housed in a surface-mount SO-8 package (JEDEC MS-012AA) with exposed drain pads for improved thermal performance. The leadframe is modified for lower thermal resistance and supports multiple-die integration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 7, 8 | Drain (D) | Internally connected drain terminals - provide parallel current paths and low-inductance heat sinking to PCB copper |
| 6 | Gate (G) | Control input - requires ≤±20 V drive; Miller charge (12–18 nC) dominates turn-off timing |
| Source (S) | Source (S) | Reference node for gate drive and load return - tied to system ground in low-side configuration |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) | 13.5 mΩ @ -10 V enables >95% efficiency in 5 V/10 A load switches |
| Logic-level compatible | Guaranteed turn-on at VGS = -4.5 V supports direct MCU control without external drivers |
| Enhanced SO-8 thermal design | Custom leadframe reduces RθJA by ~25% vs. standard SO-8, enabling higher power density |
| Fast body diode | 40–60 ns trr and low Qrr allow use in synchronous buck topologies without added Schottky |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si7157DP-T1-GE3 | RDS(on) = 12.5 mΩ @ -10 V; Qg = 65 nC; SO-8, same pinout | Slightly lower gate charge improves switching efficiency above 200 kHz | Preferred for high-frequency DC-DC output stages where gate drive loss dominates |
| IPD95R1K2P7ATMA1 | 950 V rating, 1.2 Ω RDS(on), TO-252 package - not pin-compatible | Designed for AC-DC primary-side switching, not low-voltage load control | Only suitable if system requires >60 V blocking and can accommodate larger footprint and higher RDS(on) |
Compared with Si7157DP-T1-GE3, IRF7424PBF offers higher pulsed current (−47 A vs −40 A) and better thermal resistance in SO-8; versus IPD95R1K2P7ATMA1, it delivers 100× lower RDS(on) at 30 V but lacks HV isolation capability.

FAQ
What is the maximum safe operating voltage for IRF7424PBF in continuous DC operation?
The absolute maximum drain-to-source voltage is -30 V under all conditions, including transient spikes. Operation beyond this rating risks avalanche breakdown and permanent damage. Derating is not specified; design margins must be applied based on system-level surge testing per IEC 61000-4-5.
Can IRF7424PBF be used in a high-side switch configuration with 5 V logic control?
Yes - its gate threshold voltage range (-1.0 V to -2.5 V) and guaranteed RDS(on) of 22 mΩ at VGS = -4.5 V enable direct drive from 5 V microcontrollers. A pull-up resistor to VIN is required for high-side topology to ensure proper gate bias relative to source.
Does IRF7424PBF have an integrated ESD protection diode on the gate?
No - the device does not include on-chip gate ESD protection. External Zener clamping (e.g., 12 V TVS between gate and source) is recommended when routing gate traces outside shielded areas or connecting to connectors subject to human handling.
How does the SO-8 package modification affect PCB layout requirements?
The modified SO-8 leadframe increases copper exposure on pins 1–5 and 7–8, requiring full-solder mask opening over all drain pads. Thermal vias under the drain pad array (minimum 6 × 0.3 mm) are essential to achieve rated RθJA; insufficient copper area raises junction temperature by >30 °C at 2.5 W.
