Product details
Overview
IRF6617TR1PBF from Infineon Technologies (formerly International Rectifier) is an N-channel enhancement-mode power MOSFET in DirectFET® ST package, optimized for high-frequency synchronous buck converters in CPU core DC-DC applications. It delivers 8.1 mΩ RDS(on) at VGS = 10 V, 10.3 mΩ at 4.5 V, 11 nC total gate charge, and ultra-low 0.7 mm profile with dual-sided cooling capability.
For engineers reviewing the IRF6617TR1PBF datasheet, IRF6617TR1PBF pinout, IRF6617TR1PBF application, or IRF6617TR1PBF equivalent, key selection criteria include RDS(on) vs. VGS trade-off, gate charge minimization for high-frequency switching, thermal resistance under double-sided PCB mounting, and compatibility with Micro8™ footprint layouts per AN-1035.
Technical Context
This MOSFET employs HEXFET® silicon with DirectFET® ST packaging to achieve simultaneous low conduction loss (RDS(on) = 6.2 mΩ typ. @ 10 V) and low switching loss (Qgd = 4.0 nC, Qsw = 5.0 nC). Its gate threshold voltage (1.35–2.35 V) and negative temperature coefficient (∆VGS(th)/∆TJ = −5.4 mV/°C) support stable operation across −40°C to +150°C junction range.
The device integrates a robust body diode with 16 ns typical reverse recovery time and 7.2 nC Qrr, enabling efficient unclamped inductive switching. Thermal design leverages RθJC = 3.0°C/W and RθJ-PCB = 1.0°C/W when mounted with metalized backside and clip heatsink per layout guidelines in AN-1035.

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 |
|---|---|---|---|
| IRF6622TRPBF | RDS(on) = 4.8 mΩ @ 10 V, Qg = 17 nC, same DirectFET ST package | Better conduction loss but higher switching loss; requires stronger gate driver | Preferred where conduction loss dominates (e.g., low-frequency, high-current phases); less suitable for >500 kHz operation |
| SiR626DP-T1-GE3 | RDS(on) = 7.0 mΩ @ 10 V, Qg = 12.5 nC, PowerPAK® 1212-8 package (1.2 mm height) | Higher profile, no dual-sided cooling; 20% larger footprint than DirectFET ST | Used where legacy layout reuse is required; not recommended for ultra-thin or thermally constrained designs |
Compared with IRF6622TRPBF and SiR626DP-T1-GE3, the IRF6617TR1PBF offers optimal balance of RDS(on), Qg, and thermal performance in minimal height - making it uniquely suited for next-gen CPU/GPU VRMs where both efficiency and vertical space are limiting factors.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The IRF6617TR1PBF has a specified operating junction temperature range of −40°C to +150°C. For reliable continuous operation, junction temperature must remain ≤150°C under worst-case thermal conditions - verified using RθJ-PCB = 1.0°C/W with double-sided cooling and proper PCB copper area per AN-1035 layout guidelines.
Is IRF6617TR1PBF pin-compatible with other DirectFET ST devices?
Yes - all DirectFET ST-outline devices (e.g., IRF6615, IRF6622) share identical mechanical footprint, terminal locations, and solder pad geometry. This enables direct layout reuse across the family, provided thermal and electrical derating align with each part's RDS(on) and Qg specifications.
Does this MOSFET require special soldering profiles due to its DirectFET construction?
No - IRF6617TR1PBF is qualified for standard lead-free reflow up to 260°C peak temperature. However, AN-1035 mandates specific stencil design (0.12 mm thickness, 0.35 mm aperture) and substrate plating (ENIG or immersion silver) to ensure void-free solder joints and optimal thermal transfer through the bottom source pad.
Can IRF6617TR1PBF be used in avalanche-rated applications?
It supports single-pulse avalanche energy up to 120 mJ (at IAS = 12 A, starting TJ = 25°C), but is not characterized or guaranteed for repetitive avalanche operation. Designers must limit operation to clamped inductive switching with external snubbers or synchronous rectification to avoid cumulative junction degradation.
