Product details
Overview
IRF6626TR1 from Infineon Technologies (formerly International Rectifier) is a 30 V, 16 A N-channel Power MOSFET in DirectFET™ ST package, optimized for synchronous buck converters in CPU core DC-DC applications. It delivers 4.0 mΩ RDS(on) @ 10 V, 19 nC total gate charge, and ultra-low 0.7 mm profile with dual-sided cooling capability.
For engineers reviewing the IRF6626TR1 datasheet, IRF6626TR1 pinout, IRF6626TR1 application, or IRF6626TR1 equivalent, this part is selected for high-frequency switching power stages where conduction loss, switching loss, and thermal resistance are critical - especially in 12 V input, multiphase VRMs powering modern processors.
Technical Context
The IRF6626TR1 employs HEXFET® silicon in a copper-can DirectFET™ ST package with top-side drain terminals and bottom-side source/gate connections. Its layout enables dual-sided PCB cooling and achieves 3.0 °C/W junction-to-case thermal resistance.
It is specifically tuned for synchronous FET roles in buck converters: low Qgd/Qg ratio (6.7 nC / 19 nC), 5.2 mΩ RDS(on) @ 4.5 V, and 260 pF Crss support fast, low-loss transitions at >1 MHz switching frequencies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Withstands 12 V bus transients with margin in synchronous buck high-side or low-side positions. |
| RDS(on) @ 10 V | 4.0 mΩ - Enables ≤1 W conduction loss at 16 A continuous current in compact VRM layouts. |
| Qg Total | 19 nC - Reduces gate drive power and allows use of smaller, lower-cost gate drivers in high-frequency designs. |
| Qgd | 6.7 nC - Low Miller charge minimizes switching delay and improves immunity to dv/dt-induced turn-on in hard-switched topologies. |
| RθJC | 3.0 °C/W - Supports direct heatsink mounting to top drain surface, enabling dual-sided thermal path for <10 °C temperature rise at 20 W dissipation. |
| Package Height | 0.7 mm - Fits under low-profile VRM inductors and enables dense, stacked power stage layouts on thin PCBs. |
Pinout & Package
IRF6626TR1 uses the DirectFET™ ST (Small Size Can, T-Designation) package: a copper-can, top-drain, bottom-source/gate configuration with 7 terminals (dual drain pads, dual source pads, single gate). Dimensions: 4.8 × 3.9 × 0.7 mm. Compatible with MICRO-8 footprint layouts and standard SMT reflow processes per AN-1035.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 6, 7 (Drain) | Drain connection (top-side copper can) | Provides low-inductance, high-current path and primary thermal interface for heatsink mounting. |
| 3, 4 (Source) | Source connection (bottom-side pads) | Minimizes source loop inductance in synchronous FET placement; connects directly to ground plane. |
| 5 (Gate) | Gate control terminal (bottom-side pad) | Enables short, low-impedance gate routing adjacent to source; supports tight gate loop design. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-sided cooling | Top-side drain and bottom-side source/gate allow simultaneous thermal interface to heatsink and PCB, improving thermal resistance by 80% vs. SO-8. |
| Ultra-low package inductance | DirectFET™ construction reduces parasitic LDS and LGS, enabling clean switching waveforms above 1 MHz without snubbers. |
| Optimized for 4.5 V drive | 5.2 mΩ RDS(on) @ 4.5 V supports logic-level gate drivers in space-constrained VRMs without level-shifting circuitry. |
| Synchronous FET + Control FET capable | Low Qgd/Qg ratio and 1.8 V VGS(th) enable reliable operation in both low-side sync-FET and high-side control-FET roles. |
Applications
| Server CPU Core VRM | GPU Power Delivery |

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 |
|---|---|---|---|
| IRF6614TR1PBF | Same DirectFET™ ST package but 3.3 mΩ RDS(on) @ 10 V and 22 nC Qg; higher gate charge increases driver loss. | Better conduction loss at cost of higher switching loss; suited for lower-frequency (<600 kHz), higher-current phases. | Select when RDS(on) dominates system loss budget and gate drive capability permits higher Qg. |
| SiR626DP-T1-GE3 | Vishay 30 V TrenchFET® in PowerPAK® 1212-8; 4.2 mΩ @ 10 V, 17 nC Qg, but 1.0 mm height and single-sided cooling only. | Higher RθJA (25 °C/W vs. 12.5 °C/W with dual cooling); less effective in thermally dense VRMs. | Choose if existing layout uses PowerPAK footprint and thermal headroom exceeds 15 °C/W junction-to-ambient. |
Compared with IRF6626TR1, IRF6614TR1PBF trades higher gate charge for lower RDS(on), while SiR626DP-T1-GE3 sacrifices thermal performance for broader distributor availability - making IRF6626TR1 optimal for space- and thermally constrained high-frequency CPU/GPU VRMs.

FAQ
What is the maximum continuous drain current for IRF6626TR1 at 70°C ambient?
The IRF6626TR1 supports 13 A continuous drain current at TA = 70°C with proper PCB copper area and airflow. This rating assumes surface mounting on a 1 in² copper board per datasheet condition h. Derating is linear at 17 mW/°C above 70°C ambient.
Can IRF6626TR1 be used as a high-side control FET in a synchronous buck converter?
Yes - its 1.8 V gate threshold voltage, 5.2 mΩ RDS(on) @ 4.5 V, and low Qgd (6.7 nC) support robust high-side operation with bootstrap gate drivers. However, external level-shifting is required for 10 V drive due to lack of integrated charge pump.
Does IRF6626TR1 include an integrated Schottky diode?
No. The IRF6626TR1 contains only the intrinsic body diode of the N-channel MOSFET. Its reverse recovery charge (Qrr) is 5.4 nC, and trr is 15 ns - typical for silicon HEXFET devices. External Schottky or GaN co-packaged diodes are not integrated.
Is the DirectFET™ ST package RoHS-compliant and lead-free?
Yes. IRF6626TR1 is manufactured in a lead-free, RoHS-compliant process. The DirectFET™ ST package uses matte tin-plated copper leads and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), allowing unlimited floor life before reflow.
