Product details
Overview
IRF7822TRPBF from Infineon Technologies is an N-channel HEXFET® Power MOSFET in SO-8 package, optimized for synchronous buck converters in CPU core power delivery. It delivers 5.0 mΩ RDS(on) at VGS = 4.5 V, 44 nC total gate charge, and 150 µA IDSS leakage at 100°C - enabling high-efficiency DC-DC conversion in microprocessor VRMs.
For engineers reviewing the IRF7822TRPBF datasheet, IRF7822TRPBF pinout, IRF7822TRPBF application, or IRF7822TRPBF equivalent, key selection criteria include low RDS(on)/QG ratio (114 Ω·nC), Cdv/dt immunity for synchronous FET operation, and SO-8 thermal performance with RθJA = 40 °C/W on standard PCB.
Technical Context
This MOSFET employs trench-gated HEXFET technology to minimize conduction and switching losses simultaneously. Its 5.0 mΩ RDS(on) at 4.5 V gate drive and 9.0 nC QGD support fast, low-loss switching in high-frequency synchronous buck topologies.
The device features enhanced Cdv/dt immunity to prevent false turn-on during high-slew-rate transitions, validated by 120 nC reverse recovery charge (Qrr) and 1.0 V source-drain diode forward voltage at 15 A - critical for robust body-diode commutation in multiphase VRMs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - supports input rails up to 24 V in CPU core converters with margin |
| RDS(on) | 5.0 mΩ @ VGS = 4.5 V - enables <1.5 W conduction loss at 15 A output current |
| QG | 44 nC @ VGS = 5.0 V - balances gate drive strength and switching speed for 300–1000 kHz operation |
| QGD | 9.0 nC - minimizes Miller plateau duration and improves hard-switching robustness |
| RθJA | 40 °C/W - allows ≥3.0 W continuous power dissipation on 1-inch² copper PCB |
| VGS(th) | 1.0 V - ensures reliable enhancement-mode turn-on with 3.3 V or 5 V gate drivers |
| ID (TA = 70°C) | 13 A - defines maximum continuous current under typical VRM board temperature conditions |
Pinout & Package
IRF7822TRPBF uses the industry-standard SO-8 surface-mount package (JEDEC MS-012AA), with exposed drain pads on pins 1–4 and 6–8 for thermal and electrical connection. The package supports vapor-phase, IR, convection, and wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–4, 6–8 (D) | Drain | Parallel-connected drain terminals form low-inductance, high-current path to ground plane |
| 5 (G) | Gate | Single gate input with 1.5 Ω internal gate resistance - reduces ringing without external damping |
| 7–8 (S) | Source | Common-source connection for synchronous FET; ties to power ground return path |
Key Features
| Feature | Design Value |
|---|---|
| Optimized RDS(on)/QG ratio | 114 Ω·nC - maximizes efficiency across 300–1000 kHz switching frequencies in VRMs |
| Cdv/dt-induced turn-on immunity | Validated via low QGD/QG ratio (20.5%) - prevents spurious turn-on during high dV/dt transitions |
| Low reverse recovery charge | Qrr = 120 nC - reduces body-diode switching loss and EMI in discontinuous conduction mode |
| Lead-free SO-8 packaging | RoHS-compliant, JEDEC MS-012AA outline - compatible with standard SMT reflow profiles |
| High-temperature leakage control | IDSS = 150 µA @ TJ = 100°C - maintains stability in thermally constrained VRM layouts |

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 |
|---|---|---|---|
| IRF7832TRPBF | RDS(on) = 3.3 mΩ @ 4.5 V; QG = 52 nC; higher conduction efficiency but increased switching loss | Better suited for lower-frequency (<500 kHz), high-current phases where conduction dominates | Select when prioritizing full-load efficiency over light-load EMI or gate drive capability |
| SiR872DP-T1-GE3 | RDS(on) = 4.2 mΩ @ 4.5 V; QG = 39 nC; tighter RDS(on) distribution and lower QGD/QG ratio | Enhanced Cdv/dt immunity and improved gate drive margin in ultra-high-speed (>1 MHz) VRMs | Select when operating above 800 kHz or requiring tighter parametric consistency across production lots |
Compared with IRF7822TRPBF, IRF7832TRPBF trades higher gate charge for lower RDS(on), while SiR872DP-T1-GE3 offers superior gate charge linearity and Cdv/dt margin - making it preferable for high-frequency, high-reliability AI/ML accelerator power stages.

FAQ
Is IRF7822TRPBF suitable for synchronous rectification in buck converters?
Yes. Its low 5.0 mΩ RDS(on) at 4.5 V, 120 nC Qrr, and 1.0 V VSD make it ideal as a low-side synchronous FET in buck converters. The device's Cdv/dt immunity prevents false turn-on during high-slew-rate transitions, ensuring robust commutation in multi-phase VRMs.
What is the maximum continuous drain current at 85°C ambient temperature?
At TA = 85°C, derating from the 13 A rating at 70°C yields approximately 9.5 A continuous drain current, based on its 40 °C/W RθJA and 150°C max junction temperature. This assumes 1-inch² copper pad and still-air convection cooling per JEDEC standards.
Does IRF7822TRPBF require a gate resistor for stable operation?
A small gate resistor (2–10 Ω) is recommended to dampen ringing caused by PCB trace inductance and MOSFET input capacitance. The device's internal 1.5 Ω RG provides partial damping, but external resistance improves EMI and shoot-through margin in high-speed, high-current VRM designs.
Can IRF7822TRPBF be used in place of IRF7807 in existing designs?
Yes, with validation. Both are SO-8 N-channel MOSFETs, but IRF7822TRPBF offers 5.0 mΩ vs. IRF7807's 7.0 mΩ RDS(on) and lower QG (44 nC vs. 55 nC). Gate threshold (1.0 V) and VDS (30 V) match, so no driver changes are needed - however, layout thermal performance must be verified due to higher power density.
