Product details
Overview
IRF6894MTR1PBF from Infineon Technologies is a 25 V, 37 A N-channel Power MOSFET in DirectFET™ MX package with integrated Schottky diode, optimized for synchronous buck converter high-side and low-side (Sync FET) sockets. It delivers 0.9 mΩ RDS(on) @ 10 V, 31 nC total gate charge, and dual-sided cooling capability for CPU core DC-DC converters.
For engineers reviewing the IRF6894MTR1PBF datasheet, IRF6894MTR1PBF pinout, IRF6894MTR1PBF application, or IRF6894MTR1PBF equivalent, key selection criteria include ultra-low on-resistance at 4.5 V gate drive, Qrr of 58 nC for reduced switching loss in high-frequency operation, thermal resistance RθJC of 2.3 °C/W, and compatibility with existing SO-8 footprint layouts.
Technical Context
This MOSFET employs HEXFET® silicon with DirectFET™ MX packaging-metal-can, top-drain, double-sided thermal interface-to achieve sub-1 mΩ conduction resistance while maintaining low gate charge (Qg = 31 nC) and gate resistance (RG = 0.2 Ω). Its integrated monolithic Schottky diode reduces body diode Qrr by suppressing minority carrier storage.
The device is characterized for operation up to 150 °C junction temperature, with VGS(th) = 1.6 V (typ), dVGS(th)/dTJ = −3.8 mV/°C, and avalanche-rated EAS = 540 mJ. It supports high-frequency PWM switching in synchronous rectification due to fast turn-on (td(on) = 17 ns) and turn-off (td(off) = 23 ns) delays under 4.5 V drive.
Key Specifications

Pinout & Package
IRF6894MTR1PBF uses the DirectFET™ MX (Medium Can, X-designation) package: metal-can, top-drain, bottom-source/gate terminals, 0.7 mm profile, SO-8 footprint-compatible layout. Dimensions: 6.3 mm × 5.05 mm × 0.7 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

|---|---|
| Dual-sided cooling interface | Enables simultaneous top-can and bottom-pad thermal transfer, improving RθJA by 80% vs. SO-8 packages. |
| Integrated monolithic Schottky diode | Reduces Qrr to 58 nC, eliminating external diode need and minimizing dead-time losses in sync buck. |
| Low-profile 0.7 mm height | Allows dense component placement in space-constrained VRM modules and mobile computing power stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRF6662TRPbF | RDS(on) = 1.3 mΩ @ 10 V; Qg = 22 nC; no integrated Schottky diode | Higher Qrr (105 nC) increases switching loss in high-frequency sync buck | Preferred where gate drive strength is limited and thermal budget allows higher RDS(on) |
| SIZ202DT-T1-GE3 | RDS(on) = 0.85 mΩ @ 10 V; Qg = 35 nC; TrenchFET® Gen IV, PQFN 5×6 mm | Higher gate charge increases driver loss; no top-side cooling interface | Selected when board-level thermal design favors bottom-side-only heatsinking |

FAQ
What is the maximum continuous drain current at 70°C ambient?
The IRF6894MTR1PBF supports 29 A continuous drain current at TA = 70°C with VGS = 10 V, based on silicon-limited rating and thermal derating per RθJA = 12.5 °C/W (double-sided cooled). This value assumes proper PCB copper area and airflow per AN-1035 guidelines.
Does this MOSFET require a gate resistor for stability?
Yes-a gate resistor (typically 1–5 Ω) is recommended to dampen ringing caused by low RG (0.2 Ω) and parasitic inductance in high-di/dt switching. The datasheet specifies tr = 47 ns and tf = 13 ns with RG = 1.8 Ω, confirming design sensitivity to gate loop inductance.
Can IRF6894MTR1PBF be used in parallel configurations?
Yes-its positive RDS(on) temperature coefficient (0.02 %/°C) enables inherent current sharing. Parallel operation requires matched gate drive paths, symmetrical layout, and shared thermal interface to avoid thermal runaway; typical designs use 2–4 devices per phase.
Is the integrated Schottky diode rated for continuous conduction?
No-the integrated Schottky diode is optimized for reverse recovery suppression during synchronous rectification, not continuous forward conduction. Its forward voltage is 0.75 V at 30 A and 25°C, but sustained source current must remain within the MOSFET's 37 A continuous rating (TJ ≤ 150°C) and thermal limits.
