Product details
Overview
IRF7822TRR from Infineon Technologies is an N-channel HEXFET® Power MOSFET in SO-8 package, optimized for synchronous buck DC-DC converters. It delivers 5.0 mΩ RDS(on) at VGS = 4.5 V, 44 nC total gate charge, and 30 V VDS, enabling high-efficiency CPU core power delivery in notebook and server VRMs.
For engineers reviewing the IRF7822TRR datasheet, IRF7822TRR pinout, IRF7822TRR application, or IRF7822TRR equivalent, key selection criteria include low conduction loss (5.0 mΩ), high Cdv/dt immunity for synchronous FET operation, thermal resistance (RθJA = 40 °C/W), and SO-8 footprint compatibility with standard PCB assembly processes.
Technical Context
The IRF7822TRR employs advanced trench-gate HEXFET technology to minimize both RDS(on) and QG, achieving a balanced trade-off for high-frequency synchronous rectification. Its gate threshold voltage (VGS(th) = 1.0 V typ.) supports 4.5 V logic-level drive, and its body diode exhibits 1.0 V forward voltage at 15 A.
Designed specifically for low-side switching in synchronous buck topologies, the device features enhanced immunity to Cdv/dt-induced turn-on and reduced Qoss (27 nC) to limit switching losses during hard commutation events typical in microprocessor VRMs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum blocking voltage compatible with 24 V input rails and transient margin in point-of-load converters |
| RDS(on) | 5.0 mΩ @ VGS = 4.5 V, ID = 15 A - Enables <1 W conduction loss at 15 A, critical for thermally constrained VRM layouts |
| QG | 44 nC @ VGS = 5.0 V - Determines gate driver current requirement and switching speed in 300–1000 kHz VRM designs |
| RθJA | 40 °C/W - Defines thermal derating on standard 1-inch² copper; limits continuous ID to 13 A at TA = 70 °C |
| VGS(th) | 1.0 V typ. - Ensures reliable enhancement-mode turn-on with 3.3 V or 5 V gate drivers without overdrive risk |
| Qoss | 27 nC @ VDS = 16 V - Directly impacts turn-off energy loss and EMI in hard-switched synchronous FET operation |
Pinout & Package
IRF7822TRR is housed in a standard SO-8 surface-mount package (JEDEC MS-012AA), optimized for vapor-phase, infrared, convection, and wave soldering. The package supports >3 W power dissipation in typical PCB mount configurations and features exposed drain pads for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 7, 8 | Drain (D) | Internally paralleled drain terminals - provide low-inductance, high-current path to output rail and thermal pad |
| 5 | Gate (G) | Single gate input - requires low-impedance drive to control 15 A load with minimal QG-related delay |
| 6 | Source (S) | Common source node - serves as return path for load current and reference for gate drive in low-side configuration |
Key Features
| Feature | Design Value |
|---|---|
| Optimized for synchronous buck FETs | High Cdv/dt immunity prevents false turn-on during high dV/dt transitions across high-side switch |
| Low RDS(on) + low QG balance | Reduces combined conduction and switching losses in 500 kHz–1 MHz VRMs powering modern CPUs |
| Body diode with low Qrr | 120 nC reverse recovery charge minimizes shoot-through risk and associated power loss in synchronous rectification |
| SO-8 footprint with thermal pad | Enables drop-in replacement in existing VRM layouts while supporting >3 W dissipation via PCB copper area |

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) = 4.0 mΩ @ 4.5 V, higher QG (52 nC), same SO-8 package | Better conduction loss but slower switching; suited for lower-frequency (<400 kHz) VRMs where thermal headroom exists | Prefer IRF7832TRPBF when peak efficiency at light-to-moderate loads outweighs switching loss penalty |
| SiR872DP-T1-GE3 | RDS(on) = 4.8 mΩ @ 4.5 V, QG = 39 nC, same SO-8, Vishay Gen 3 TrenchFET | Lower gate charge improves high-frequency efficiency; slightly lower VDS rating (25 V) limits use to ≤19 V input rails | Select SiR872DP-T1-GE3 for 12 V input VRMs prioritizing 1 MHz+ operation and tighter layout constraints |
Compared with IRF7822TRR, IRF7832TRPBF trades higher gate charge for lower RDS(on), favoring thermally limited but lower-frequency designs, while SiR872DP-T1-GE3 offers faster switching at marginally reduced voltage rating-making IRF7822TRR the optimal balance for 24 V-input, 500–800 kHz CPU VRMs.

FAQ
What is the maximum continuous drain current for IRF7822TRR at 70°C ambient temperature?
The IRF7822TRR supports 13 A continuous drain current at TA = 70°C, as specified in its Absolute Maximum Ratings table. This value assumes standard SO-8 mounting on a 1-inch² copper board and accounts for thermal derating due to RθJA = 40 °C/W. At 25°C ambient, the rating increases to 18 A, but system-level thermal design must verify junction temperature remains below 150°C under worst-case load and airflow conditions for IRF7822TRR.
Does IRF7822TRR support 3.3 V gate drive in synchronous buck applications?
Yes, IRF7822TRR is fully compatible with 3.3 V gate drive due to its low 1.0 V typical gate threshold voltage (VGS(th)) and guaranteed RDS(on) of 6.5 mΩ max at VGS = 4.5 V. While optimal RDS(on) (5.0 mΩ) is specified at 4.5 V, the device remains strongly enhanced at 3.3 V, delivering usable on-resistance and safe switching margins in space-constrained VRMs where 5 V gate bias is unavailable. IRF7822TRR has been validated in such configurations per Infineon application note AN-1001.
What is the purpose of the multiple drain pins (pins 1, 2, 3, 4, 7, 8) on IRF7822TRR?
The six paralleled drain pins on IRF7822TRR reduce package inductance and thermal resistance by distributing high-frequency, high-current paths across multiple bond wires and leads. This configuration lowers effective RDS(on) contribution from leadframe resistance and minimizes voltage spikes during fast dI/dt transitions-critical for stability in multi-phase CPU VRMs. Each drain pin connects directly to the internal die's drain metallization and the exposed thermal pad, making IRF7822TRR's SO-8 layout inherently optimized for both electrical and thermal performance.
How does the body diode performance of IRF7822TRR impact synchronous rectification?
The IRF7822TRR body diode exhibits 1.0 V forward voltage at 15 A and 120 nC reverse recovery charge (Qrr), enabling predictable freewheeling behavior during dead-time intervals. Its low Qrr reduces energy loss and EMI during diode conduction, while the well-controlled reverse recovery minimizes cross-conduction risk in synchronous buck topologies. These characteristics make IRF7822TRR suitable as either high-side or low-side switch, though it is optimized as the low-side FET where body diode conduction is most frequent and impactful.
Is IRF7822TRR qualified for automotive applications?
No, IRF7822TRR is explicitly qualified for the Consumer market per its datasheet revision notes and is not AEC-Q101 qualified. It lacks automotive-specific stress testing, extended temperature screening, and failure analysis reporting required for under-hood or safety-critical systems. For automotive DC-DC converters, Infineon recommends AEC-Q101-qualified alternatives such as the IPB120N04S4L-H0, which shares similar RDS(on) and SO-8 packaging but meets full automotive reliability standards. IRF7822TRR remains appropriate for industrial, computing, and telecom applications.
