Product details
Overview
IRF6617TR1 from Infineon Technologies (formerly International Rectifier) is an N-channel 30V HEXFET® Power MOSFET in DirectFET® ST package, optimized for high-frequency synchronous buck converters in CPU core DC-DC applications. It delivers 6.2 mΩ RDS(on) @ VGS = 10 V, 11 nC total gate charge, and ultra-low 0.7 mm profile with dual-sided cooling capability.
For engineers reviewing the IRF6617TR1 datasheet, IRF6617TR1 pinout, IRF6617TR1 application, or IRF6617TR1 equivalent, key selection criteria include RDS(on) at 4.5 V (10.3 mΩ), Qgd (4.0 nC), thermal resistance RθJC (3.0 °C/W), body diode trr (16–24 ns), and compatibility with vapor-phase reflow per AN-1035.
Technical Context
The IRF6617TR1 employs trench-gate silicon technology and DirectFET ST packaging to minimize both conduction loss (via low RDS(on)) and switching loss (via low Qg, Qgd, and package inductance). Its gate threshold voltage (1.35–2.35 V) and negative temperature coefficient (∆VGS(th)/∆TJ = −5.4 mV/°C) support stable parallel operation in multiphase VRMs.
Designed specifically for control-FET roles in 30 V input synchronous buck topologies, it features a fully rated 55 A continuous drain current at TC = 25 °C, 120 mJ single-pulse avalanche energy, and 1.0 µA IDSS leakage - enabling robust operation under transient overvoltage and high-temperature conditions typical in server and desktop CPU power delivery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage compatible with 24 V input bus and transient margin in CPU VRMs |
| RDS(on) max @ 10 V | 8.1 mΩ - Enables <1 W conduction loss at 15 A, critical for >90% efficiency targets |
| RDS(on) max @ 4.5 V | 10.3 mΩ - Ensures stable on-resistance during low-voltage gate drive in adaptive voltage positioning (AVP) |
| Qg typ. | 11 nC - Reduces gate driver power loss and enables fast turn-on (<11 ns delay) at high PWM frequencies |
| Qgd typ. | 4.0 nC - Limits Miller-induced shoot-through risk and improves hard-switching robustness |
| RθJC | 3.0 °C/W - Supports dual-sided cooling to sustain >40 W power dissipation with <10 °C junction-to-case rise |
| trr | 16–24 ns - Minimizes body diode reverse recovery loss during dead-time conduction in synchronous rectification |
Pinout & Package
The IRF6617TR1 uses the DirectFET® ST (Small Size Can, T-Designation) package - a top-side-drain, bottom-side-source/gate copper can structure with 0.7 mm height, 4.75 × 3.70 mm footprint, and no leads. It mounts directly to PCBs via soldered copper pads on both sides for enhanced thermal transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Top Metal Pad | Drain (D) | Primary high-current path; serves as thermal interface for heatsink or copper plane on board top side |
| Bottom Left Pad | Source (S) | Low-impedance return path; connects to ground plane and provides primary thermal path to PCB |
| Bottom Right Pad | Gate (G) | Control terminal; isolated pad minimizes coupling to high-dI/dt drain node and reduces EMI |
Key Features
| Feature | Design Value |
|---|---|
| DirectFET ST packaging | 0.7 mm profile enables ultra-thin VRM designs while supporting dual-sided cooling for 80% lower RθJA vs. SO-8 |
| Ultra-low Qgd/Qg ratio | 36% - Improves switching efficiency and reduces gate drive losses in 300–1000 kHz buck converters |
| Optimized RDS(on) vs. Qg trade-off | 6.2 mΩ / 11 nC - Balances conduction and switching loss for best FOM (RDS(on) × Qg = 68 mΩ·nC) |
| Enhanced avalanche ruggedness | 120 mJ EAS - Withstands unclamped inductive switching events in high-current CPU load transients |
| Low Crss (160 pF) | Reduces Miller feedback, enabling stable operation with standard gate drivers without external Miller clamp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-frequency power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRF6622TR1PBF | 30 V, 5.5 mΩ @ 10 V, 14.5 nC Qg, same DirectFET ST package | Lower RDS(on) but higher Qg; better for low-frequency, high-current phases; less optimal for high-frequency light-load efficiency | Select when conduction loss dominates; avoid if gate drive capability is limited or switching frequency exceeds 700 kHz |
| SiR626DP-T1-GE3 | 30 V, 6.0 mΩ @ 10 V, 10.5 nC Qg, PowerPAK® SO-8L package (1.05 mm height) | Higher profile and single-sided cooling only; RθJA ≈ 58 °C/W vs. IRF6617TR1's 12.5 °C/W (dual-sided) | Select only when DirectFET assembly infrastructure is unavailable; expect ~25% higher thermal resistance and reduced power density |
Compared with IRF6622TR1PBF and SiR626DP-T1-GE3, the IRF6617TR1 offers the best balance of low Qg, low RDS(on), and ultra-low profile - making it uniquely suited for space-constrained, high-efficiency CPU VRMs where thermal management and switching speed are co-critical.

FAQ
What is the maximum continuous drain current for IRF6617TR1 at 70°C ambient?
The IRF6617TR1 supports 11 A continuous drain current at TA = 70 °C with standard PCB mounting (1 in² Cu), as specified in the Absolute Maximum Ratings table. This value assumes natural convection and accounts for RθJA = 58 °C/W. Dual-sided cooling increases effective current handling significantly - up to 42 A at TC = 25 °C per the datasheet.
Is IRF6617TR1 RoHS-compliant and halogen-free?
Yes. The IRF6617TR1 is RoHS-compliant and halogen-free per Infineon's material declarations. It meets JEDEC J-STD-609 Class 1 for moisture sensitivity (MSL-1), and its DirectFET ST package contains no leaded solder or brominated flame retardants. Full compliance documentation is available via Infineon's Quality Portal.
Can IRF6617TR1 be used in parallel configurations?
Yes - its negative VGS(th) temperature coefficient (−5.4 mV/°C) and matched RDS(on) distribution enable stable current sharing in parallel operation. Designers must ensure symmetrical PCB layout, matched gate drive impedance, and thermal coupling between devices. Application note AN-1035 provides layout guidelines for multi-device DirectFET arrays.
What is the recommended gate resistor value for IRF6617TR1 in a 500 kHz buck converter?
A 2.2 Ω to 4.7 Ω gate resistor is recommended for 500 kHz operation to balance switching speed (minimizing tr/tf) and gate driver stress. At 11 nC Qg, a 3.3 Ω resistor yields ~37 ns RC time constant - sufficient to damp ringing without excessive delay. Layout parasitics must be minimized; gate loop inductance should remain <1 nH for reliable operation.
