Product details
Overview
IRF7488TRPBF from Infineon Technologies is an N-channel enhancement-mode HEXFET® Power MOSFET in SO-8 package, rated for 80 V VDS, 24–29 mΩ RDS(on) at VGS = 10 V and ID = 3.8 A, with 38 nC total gate charge and optimized for high-frequency DC-DC converters requiring low switching loss and robust avalanche capability.
For engineers reviewing the IRF7488TRPBF datasheet, IRF7488TRPBF pinout, IRF7488TRPBF application, or IRF7488TRPBF equivalent, key selection criteria include its 80 V breakdown voltage, 29 mΩ on-resistance at 10 V drive, 38 nC gate charge, SO-8 thermal performance (RθJA = 50 °C/W), and fully characterized Coss and avalanche energy (EAS = 96 mJ).
Technical Context
This MOSFET employs a planar silicon process with optimized cell layout to achieve low RDS(on) while maintaining fast switching via reduced Qgd/Qgs ratio (12 nC / 9.1 nC) and low Crss (32 pF). Its body diode is fully specified for reverse recovery (trr = 65–98 ns, Qrr = 190–290 nC) and forward conduction (VSD = 1.3 V at 3.8 A).
The device operates across –55 °C to +150 °C junction temperature, supports unclamped inductive switching up to 3.8 A avalanche current, and features linear derating (20 mW/°C above 70 °C ambient), making it suitable for thermally constrained synchronous buck stages and point-of-load regulators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 80 V - Maximum blocking voltage for 48 V input DC-DC stages with 20 % margin |
| RDS(on) | 24–29 mΩ @ VGS = 10 V - Enables ≤0.3 W conduction loss at 3.8 A continuous drain current |
| Qg | 38 nC - Low gate charge reduces driver power and enables >1 MHz switching in hard-switched topologies |
| EAS | 96 mJ - Supports single-pulse unclamped inductive energy handling without failure in synchronous rectifier faults |
| Coss(eff) | 340 pF - Effective output capacitance simplifies snubber design and impacts zero-voltage switching thresholds |
| RθJA | 50 °C/W - Limits junction rise to ≤125 °C at 1.6 W dissipation in standard SO-8 PCB layout |
| trr | 65–98 ns - Fast body diode recovery minimizes shoot-through risk in synchronous buck high-side switching |
Pinout & Package
IRF7488TRPBF is housed in a surface-mount SO-8 (JEDEC MS-012AA) package with exposed drain pads on pins 1–4 and 6–8, gate on pin 5, and source on pins 7 and 8. Thermal pad is not electrically isolated and connects to drain potential.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 6, 8 | Drain (D) | High-current power path terminal; all connected internally to die drain; requires thermal copper pour |
| 5 | Gate (G) | Control input; 10 V threshold range (2.0–4.0 V); sensitive to ESD; requires low-impedance driver |
| 7, 8 | Source (S) | Power return and reference node for gate drive; shared with drain terminals in SO-8 layout |
Key Features
| Feature | Design Value |
|---|---|
| Low Qgd/Qg ratio | 31.6 % (12 nC / 38 nC) - Reduces Miller-induced switching delay and improves controllability in high-dV/dt environments |
| Fully characterized Coss(eff) | 340 pF - Enables accurate soft-switching timing prediction and resonant tank design |
| Specified avalanche capability | EAS = 96 mJ, IAR = 3.8 A - Allows operation in unclamped inductive circuits without external protection |
| Lead-free and RoHS-compliant | Meets JEDEC J-STD-020 reflow profile - Compatible with standard Pb-free assembly processes |
| Body diode trr & Qrr | trr = 65–98 ns, Qrr = 190–290 nC - Enables reliable synchronous rectification without external Schottky replacement |

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 |
|---|---|---|---|
| IRF7478TRPBF | Same SO-8 package, 60 V VDS, 17 mΩ RDS(on), 29 nC Qg | Limited to ≤60 V systems; lower conduction loss but reduced voltage margin | Select when input voltage stays below 48 V and lowest RDS(on) is prioritized over 80 V robustness |
| SiR872DP-T1-GE3 | Vishay 80 V TrenchFET, 3.2 mΩ RDS(on) at 10 V, 52 nC Qg, PowerPAK® SO-8 | Lower RDS(on) but higher gate charge; different thermal pad layout affects PCB layout | Choose for ultra-low conduction loss where gate drive strength and layout revision are acceptable |
Compared with IRF7478TRPBF and SiR872DP-T1-GE3, IRF7488TRPBF offers balanced trade-offs: sufficient 80 V margin for PoE and industrial 48 V rails, moderate 38 nC gate charge enabling simple gate drivers, and proven avalanche ruggedness critical for unclamped inductive loads.

FAQ
What is the maximum continuous drain current at 70°C ambient?
The IRF7488TRPBF supports 5.0 A continuous drain current at TA = 70°C with VGS = 10 V, based on its 1.6 W maximum power dissipation and 29 mΩ RDS(on). This rating assumes standard SO-8 PCB layout with 1 in² 2-oz copper and no forced airflow.
Does this MOSFET require a gate resistor for stability?
Yes - a series gate resistor (typically 5–10 Ω) is recommended to dampen ringing caused by gate loop inductance and MOSFET input capacitance (Ciss = 1680 pF). The datasheet specifies switching times with RG = 9.1 Ω, confirming its use in production designs.
Can the body diode be used for synchronous rectification?
Yes - the body diode is fully characterized with trr = 65–98 ns and Qrr = 190–290 nC at IF = 3.8 A, enabling reliable synchronous rectification in buck converters up to 1 MHz, provided gate timing avoids shoot-through during diode conduction.
Is IRF7488TRPBF pin-compatible with earlier IRF74xx devices?
No - while all IRF74xx SO-8 MOSFETs share the same outline, IRF7488TRPBF has unique internal die layout and thermal pad connection (drain-connected). Pin mapping matches SO-8 standard (pins 1–4/6–8 = D, 5 = G, 7–8 = S), but RDS(on), Qg, and avalanche specs differ significantly from IRF7410/IRF7413.
