Product details
Overview
IRF6622TRPBF from Infineon Technologies (formerly International Rectifier) is a 25 V, 12 A N-channel Power MOSFET in DirectFET® SQ package, optimized for synchronous buck converter control FETs in CPU core DC-DC applications. It delivers 4.9 mΩ RDS(on) at VGS = 10 V, 6.8 mΩ at 4.5 V, and ultra-low 11 nC total gate charge - enabling high-frequency, high-efficiency operation with dual-sided cooling capability.
For engineers reviewing the IRF6622TRPBF datasheet, IRF6622TRPBF pinout, IRF6622TRPBF application, or IRF6622TRPBF equivalent, key selection criteria include its low-profile (0.7 mm) DirectFET SQ footprint, 3.7 °C/W junction-to-case thermal resistance, and body diode recovery performance (trr = 10–15 ns, Qrr = 7.1–11 nC) critical for hard-switched synchronous rectification.
Technical Context
This MOSFET employs HEXFET® silicon in a copper-can DirectFET SQ package with top-side drain and bottom-side source/gate terminals - enabling dual-sided thermal management and sub-1 nH package inductance. Its gate threshold voltage (1.35–2.35 V) and negative temperature coefficient of VGS(th) (−5.9 mV/°C) support stable parallel operation in multiphase VRMs.
The device is characterized for clamped inductive switching (EAS = 59 mJ), avalanche-rated (IAR = 12 A), and specified for repetitive pulsed operation up to 120 A peak drain current. Gate charge partitioning (Qgs2 = 1.6 nC, Qgd = 3.8 nC) enables precise timing control in high-dV/dt synchronous buck stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 25 V - Maximum blocking voltage compatible with 12 V input bus and 5 V logic-level gate drive in point-of-load converters. |
| RDS(on) @ 10 V | 4.9 mΩ - Enables <1 W conduction loss at 15 A DC, critical for >90% efficiency in CPU core rails. |
| RDS(on) @ 4.5 V | 6.8 mΩ - Supports direct drive from 5 V PWM controllers without level-shifting, reducing BOM count. |
| Qg total | 11 nC - Low gate charge minimizes driver power and propagation delay, supporting >1 MHz switching. |
| trr / Qrr | 10–15 ns / 7.1–11 nC - Fast, low-charge body diode reduces shoot-through risk and reverse recovery loss in synchronous rectification. |
| RθJC | 3.7 °C/W - Enables effective heat extraction via PCB copper and optional clip heatsink, essential for compact VRM layouts. |
| Package | DirectFET SQ - 0.7 mm profile, metal-can construction with top-drain/bottom-source-gate layout for dual-sided cooling. |
Pinout & Package
IRF6622TRPBF uses the DirectFET® SQ (Small Size Can, Q-designation) package: a surface-mount copper can with exposed top-side drain and bottom-side source/gate terminals. Dimensions: 4.8 × 3.8 × 0.7 mm (L × W × H), RoHS-compliant lead-free finish (reflow qualified to 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Top Metal Surface | Drain (D) | Primary high-current path; thermally coupled to heatsink or PCB copper pour for dual-sided cooling. |
| Bottom Left Pad | Source (S) | Low-side return node; connects to ground plane and driver return, minimizing loop inductance. |
| Bottom Right Pad | Gate (G) | Control input; isolated pad geometry supports clean gate drive routing and EMI suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low Qg/RDS(on) ratio | 11 nC / 4.9 mΩ = 2.25 nC·mΩ - balances switching and conduction losses for optimal figure-of-merit in 500 kHz–2 MHz VRMs. |
| DirectFET SQ thermal architecture | Junction-to-case RθJC = 3.7 °C/W - improves thermal transfer by 80% vs. SO-8, enabling higher power density in thin-profile systems. |
| High Cdv/dt immunity | Specified for hard-switched operation with dV/dt > 50 V/ns - suppresses false turn-on in fast-rising synchronous buck nodes. |
| Optimized for ControlFET socket | Gate threshold (1.8 V typ.) and transconductance (55 S) tuned for stable gate drive in high-side position of synchronous buck converters. |

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 |
|---|---|---|---|
| IRF6616TRPBF | Higher RDS(on) (6.0 mΩ @ 10 V), same Qg (11 nC), identical DirectFET SQ package | Slightly lower current rating (10 A vs. 12 A); suitable for lower-power VRMs or cost-sensitive designs | Select when thermal margin allows higher RDS(on) and procurement favors older revision. |
| SiR626DP-T1-GE3 | Lower RDS(on) (4.0 mΩ @ 10 V), higher Qg (15.5 nC), PowerPAK® SO-8 package (1.7 mm height) | Requires taller board clearance; higher gate drive loss limits max frequency vs. IRF6622TRPBF | Select when lowest conduction loss is prioritized over switching speed and board height. |
Compared with IRF6622TRPBF, IRF6616TRPBF trades 22% higher conduction loss for identical switching performance and footprint, while SiR626DP-T1-GE3 reduces RDS(on) by 18% but increases gate drive demand and board height - making IRF6622TRPBF the optimal balance for space-constrained, high-frequency CPU/GPU VRMs.

FAQ
What is the maximum continuous drain current for IRF6622TRPBF at 70°C ambient?
The IRF6622TRPBF supports 12 A continuous drain current at TA = 70°C with VGS = 10 V, provided the PCB layout provides adequate copper area for thermal dissipation. This rating assumes mounting on a 1 in² copper board with still air convection and accounts for derating per the 0.017 W/°C linear factor above 70°C ambient.
Does IRF6622TRPBF require a gate resistor for stability in synchronous buck applications?
Yes - a 2–5 Ω gate resistor is recommended to dampen ringing caused by interaction between gate driver output impedance and the MOSFET's low package inductance (<1 nH). The datasheet specifies RG = 25 Ω for characterization, but practical designs use lower values (e.g., 2.2 Ω) to optimize switching speed while maintaining gate waveform integrity.
Can IRF6622TRPBF be used in parallel configurations?
Yes - its negative VGS(th) temperature coefficient (−5.9 mV/°C) and matched RDS(on) tolerance support stable current sharing in paralleled operation. Layout symmetry, individual gate resistors, and Kelvin source connections are required to ensure balanced dynamic current distribution across multiple devices in high-current VRM phases.
Is IRF6622TRPBF pin-compatible with standard SO-8 MOSFETs?
No - it uses the DirectFET SQ package with top-side drain and bottom-side source/gate pads, differing fundamentally from SO-8's through-hole or gull-wing leaded layout. While footprint area is similar to Micro-8, the terminal arrangement and thermal interface require dedicated PCB land patterns and assembly processes per AN-1035.
