Product details
Overview
IRF7425PBF from Infineon Technologies (formerly International Rectifier) is a P-channel enhancement-mode HEXFET® Power MOSFET in SO-8 package, rated for -20 V VDS, 8.2 mΩ RDS(on) at -4.5 V VGS, and -15 A continuous drain current at 25°C. It serves as a high-efficiency low-side load switch or synchronous rectifier in DC-DC converters and battery protection circuits.
For engineers reviewing the IRF7425PBF datasheet, IRF7425PBF pinout, IRF7425PBF application, or IRF7425PBF equivalent, key selection criteria include its -4.5 V logic-level gate drive compatibility, 87 nC total gate charge, body diode reverse recovery time (120–180 ns), and SO-8 thermal resistance (50 °C/W junction-to-ambient).
Technical Context
This device operates as a normally-off P-channel switch with gate threshold voltage between -0.45 V and -1.2 V, enabling direct interface with 3.3 V or 5 V microcontroller outputs. Its RDS(on) increases only 1.5× from 25°C to 125°C junction temperature, supporting stable conduction in thermally constrained layouts.
The integrated body diode exhibits -1.2 V forward voltage at -2.5 A and 25°C, with 160–240 nC reverse recovery charge under di/dt = -100 A/μs - critical for minimizing switching loss in synchronous buck topologies where it replaces external Schottky diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -20 V - Maximum blocking voltage for low-voltage battery-side switching (e.g., 12 V automotive or 5 V USB PD systems) |
| RDS(on) @ VGS = -4.5 V | 8.2 mΩ - Enables ≤120 mW conduction loss at -15 A, suitable for compact 2 W+ power stages |
| Qg | 87 nC (typ.) - Determines gate driver current requirement (~17 mA avg. for 100 kHz, 10 ns rise) |
| trr | 120–180 ns - Limits minimum off-time in synchronous rectification to avoid shoot-through |
| RθJA | 50 °C/W - Requires ≥1 in² copper pour for 2.5 W continuous dissipation at ambient 25°C |
| VGS(th) | -0.45 to -1.2 V - Ensures reliable turn-on with standard 3.3 V GPIO without level-shifting |
| Ciss | 7980 pF - Impacts gate drive loop stability and EMI filtering design in high-frequency SMPS |
Pinout & Package
SO-8 surface-mount package (JEDEC MS-012AA), 5.0 mm × 4.0 mm footprint, MSL1 rating, RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5 | Drain (D) | High-current output node; internally paralleled pins reduce package inductance and thermal resistance |
| 6 | Gate (G) | Control input; requires <100 nA leakage budget and 87 nC charge for full enhancement |
| 7, 8 | Source (S) | Return path for load current; dual pins lower source inductance for improved switching fidelity |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Operates fully enhanced down to -4.5 V VGS, eliminating need for gate driver ICs in 3.3 V systems |
| Low RDS(on) at low VGS | 13 mΩ @ -2.5 V enables use in ultra-low-voltage applications like single-cell Li-ion power paths |
| Fast body diode | 120 ns trr supports >500 kHz synchronous rectification without excessive diode loss |
| Industry-standard SO-8 | Drop-in replacement for multiple vendors' P-channel MOSFETs, simplifying second-source qualification |
Applications
| Battery Protection Circuit | USB Type-C Power Delivery Switch |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si7157DP-T1-GE3 | RDS(on) = 9.5 mΩ @ -4.5 V; Qg = 72 nC; SO-8 package | Lower gate charge reduces driver stress but slightly higher conduction loss | Preferred when gate drive capability is limited and thermal margin exceeds 10% |
| DMN2011UFG-7 | RDS(on) = 7.8 mΩ @ -4.5 V; Qg = 95 nC; 2×2 mm WDFN package | Smaller footprint and lower RDS(on), but no exposed drain pad for thermal relief | Selected for space-constrained designs where PCB area is prioritized over thermal derating |
Compared with IRF7425PBF, Si7157DP offers lower gate drive demand at modest RDS(on) penalty, while DMN2011UFG delivers superior conduction efficiency in ultra-compact layouts - choice depends on whether thermal management or board area dominates the design constraint.

FAQ
What is the maximum safe operating temperature for IRF7425PBF?
The junction temperature must not exceed +150°C, and storage temperature range is -55°C to +150°C. At 70°C case temperature, continuous drain current drops to -12 A due to thermal derating; the 20 mW/°C linear derating factor applies above 25°C ambient on a 1 in² copper board.
Does IRF7425PBF require a gate resistor for ESD protection?
No external gate resistor is required for ESD protection - the device has built-in gate protection diodes rated for ±12 V VGS. However, a 10–100 Ω series gate resistor is recommended to dampen ringing and limit peak gate current during fast switching transitions.
Can IRF7425PBF be used in parallel with identical units?
Yes - its positive temperature coefficient of RDS(on) ensures current sharing stability. Parallel operation requires matched layout symmetry, equal gate drive routing, and shared thermal plane; derate total current by 15% to account for parametric spread and thermal coupling.
Is the body diode suitable for continuous freewheeling conduction?
The body diode supports continuous conduction up to -2.5 A at 25°C (VSD = -1.2 V), but its 160–240 nC Qrr and 120–180 ns trr make it unsuitable for high-frequency freewheeling above 200 kHz without snubbing; use only in synchronous rectification or low-duty-cycle clamp applications.
