Infineon Technologies IRF6607TR1

Overview

IRF6607TR1 from Infineon Technologies is a 30V N-channel Power MOSFET in DirectFET® M package, optimized as a synchronous buck low-side FET for CPU core DC-DC converters. It delivers 3.3 mΩ R_DS(on) @ V_GS = 10 V, 50 nC total gate charge, and >80% improved thermal resistance vs. prior solutions via dual-sided cooling. Its high C_dv/dt immunity and ultra-low package inductance enable reliable operation in high-frequency, high-efficiency point-of-load regulators powering modern processors.

For engineers reviewing the IRF6607TR1 datasheet, IRF6607TR1 pinout, IRF6607TR1 application, or IRF6607TR1 equivalent, key selection criteria include R_DS(on) at 4.5 V (4.4 mΩ), Q_gd/Q_gs1 ratio for C_dv/dt immunity, junction-to-PCB thermal resistance (1.0 °C/W), and SO-8 footprint compatibility with sub-0.7 mm profile - all critical for compact, thermally constrained VRM designs.

Technical Context

The IRF6607TR1 employs trench-gate HEXFET silicon combined with copper-clip DirectFET packaging to minimize conduction loss and parasitic inductance. Its gate charge profile (Q_gs1 = 13 nC, Q_gd = 16 nC) and low Q_gd/Q_gs1 ratio (1.23) directly suppress C_dv/dt-induced turn-on in high-dV/dt synchronous nodes.

Thermally, it leverages dual-sided cooling: top-side heatsink contact and bottom-side PCB copper transfer, achieving R_θJ-PCB = 1.0 °C/W and R_θJC = 3.0 °C/W. This architecture enables sustained 94 A continuous drain current at T_C = 25 °C while maintaining <0.7 mm height for low-profile power stages.

Key Specifications

Pinout & Package

IRF6607TR1 uses the DirectFET® M package - a leadless, copper-clip construction with top-side source and drain terminals, and bottom-side gate connection. The package measures 5.0 × 6.0 mm with 0.65 mm max height and is compatible with standard SO-8 PCB footprints and reflow processes.

Compared with IRF6607TR1, IRF6617TR1PBF offers lower R_DS(on) but increases gate drive loss and thermal stress due to higher Q_g, while SiR626DP-T1-GE3 sacrifices thermal performance and height for reduced gate charge - making IRF6607TR1 optimal for thermally dense, low-profile VRMs demanding balanced conduction/switching loss.

FAQ

What is the maximum continuous drain current for IRF6607TR1 at 70°C ambient?

The IRF6607TR1 supports 22 A continuous drain current at T_A = 70°C with standard PCB mounting (no heatsink). This rating assumes 1 in² of 2 oz. copper on both sides of a 4-layer board with 1 oz. internal layers, per Infineon's thermal test conditions in the datasheet. Derating follows the linear factor of 0.029 W/°C above 70°C ambient.

Does IRF6607TR1 require a gate resistor for stability in synchronous buck applications?

Yes - a 2–5 Ω gate resistor is recommended to dampen ringing caused by low package inductance and PCB trace inductance. Infineon's application note AN-1115 specifies 3.3 Ω for optimal EMI suppression and switching speed balance in 1–2 MHz VRMs, preventing overshoot that could exceed ±12 V gate rating.

How does the DirectFET M package improve thermal performance over SO-8?

The DirectFET M package eliminates bond wires and uses copper clips to connect die to top and bottom terminals, reducing thermal resistance by 80% versus SO-8. Its R_θJ-PCB = 1.0 °C/W enables direct heat transfer to internal PCB copper, whereas SO-8 relies solely on leads and solder joints, resulting in R_θJA ≈ 35 °C/W under identical conditions.

Can IRF6607TR1 be used as a high-side switch in a floating gate configuration?

No - IRF6607TR1 is optimized as a low-side FET with source tied to ground. Its gate threshold voltage (1.0–2.0 V) and lack of integrated level-shifting circuitry make it unsuitable for high-side operation without external bootstrap or isolated gate drive. For high-side use, Infineon recommends the complementary IRF6642TR1PBF in the same package.
