Product details
Overview
DMT32M4LFG-7 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET in PowerDI3333-8 package, delivering 1.7mΩ RDS(ON) @ VGS = 10V, 100A continuous drain current at TC = +25°C, and 100% UIS-rated avalanche capability - deployed in high-density DC-DC converters for notebook GPU power rails.
For engineers reviewing the DMT32M4LFG-7 datasheet, DMT32M4LFG-7 pinout, DMT32M4LFG-7 application, or DMT32M4LFG-7 equivalent, key selection criteria include low RDS(ON) at 4.5V gate drive, Qgd × RDS(ON) figure-of-merit for synchronous buck efficiency, thermal resistance (RθJC = 3.9°C/W), and PowerDI3333-8 board-area footprint reduction versus SO-8.
Technical Context
This MOSFET employs trench-gate silicon technology optimized for low conduction loss and fast switching in high-frequency synchronous rectification. Its 3.9°C/W junction-to-case thermal resistance enables direct thermal coupling to PCB copper planes via the exposed drain pad.
The device features a gate threshold voltage of 1–3V, supports 4.5V logic-level drive, and delivers 2.8mΩ RDS(ON) under 4.5V bias - critical for 12V input/1V output multiphase VRMs where gate drive voltage is constrained by controller limitations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Maximum blocking voltage compatible with 12V input bus systems with margin for transient spikes. |
| RDS(ON) @ VGS = 10V | 1.7mΩ - Enables <1.7W conduction loss at 100A, reducing heat sink requirements in high-current power stages. |
| RDS(ON) @ VGS = 4.5V | 2.8mΩ - Ensures stable on-resistance under typical controller gate drive, minimizing dropout in 5V/3.3V auxiliary rails. |
| Qgd | 12.9nC - Low gate-drain charge reduces Miller-induced switching delay and improves hard-switching efficiency. |
| RθJC | 3.9°C/W - Allows >2.6W power dissipation at case temperature ≤100°C without external heatsink in compact layouts. |
| UIS Rating | 100% rated - Withstands single-pulse avalanche energy of 172mJ (L = 0.1mH), eliminating need for external clamping in inductive load switching. |
Pinout & Package
Package: PowerDI3333-8 - thermally enhanced 8-pin surface-mount package with exposed drain pad for direct PCB thermal conduction; occupies 33% board area of SO-8; UL 94V-0 molded compound; matte tin annealed terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (S) | Source | Four parallel source terminals reduce bond-wire inductance and improve current sharing in high-di/dt applications. |
| 5, 6, 7, 8 (D) | Drain | Four drain terminals connected to large exposed copper pad - primary thermal path to PCB ground plane. |
| Pin 1 (G) | Gate | Single gate input located adjacent to source pins to minimize gate loop inductance and suppress oscillation during fast switching. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at 4.5V | 2.8mΩ enables efficient operation with standard PWM controller gate drivers without level-shifting circuitry. |
| Optimized Qgd × RDS(ON) | 36.7 mΩ·nC - balances switching loss and conduction loss for 500kHz–1MHz synchronous buck topologies. |
| 100% UIS-rated avalanche | Validated 58A single-pulse avalanche current ensures robustness against inductive kickback in motor gate drives and DC-DC startup faults. |
| Green packaging | Halogen- and antimony-free, RoHS 3 compliant (Br+Cl <1500ppm, Sb <1000ppm), suitable for automotive and medical end equipment. |
Applications
| GPU Core Voltage Regulator | USB-C PD Fast-Charge Controller |

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 |
|---|---|---|---|
| DMTH3010LPS-13 | Same PowerDI3333-8 package, but 30V/1.4mΩ @ 10V, higher Qg (75nC) and RθJC (4.2°C/W). | Slightly lower RDS(ON) but slower switching due to higher gate charge - better for lower-frequency (<300kHz), higher-current applications. | Select when conduction loss dominates and thermal margin exceeds 2.2W; avoid in 1MHz+ VRMs due to increased switching loss. |
| SIS890DN-T1-GE3 | SO-8 package, 30V/1.8mΩ @ 10V, RθJC = 5.5°C/W, no UIS rating, larger board footprint. | Lacks avalanche ruggedness and thermal performance - requires external TVS and heatsinking in inductive loads. | Acceptable only in cost-sensitive, non-automotive consumer applications with strict SO-8 compatibility requirements. |
Compared with DMT32M4LFG-7, DMTH3010LPS-13 trades marginal RDS(ON) improvement for higher switching loss, while SIS890DN-T1-GE3 sacrifices reliability and thermal density for legacy package compatibility - making DMT32M4LFG-7 optimal for space-constrained, high-reliability DC-DC designs.

FAQ
What is the maximum continuous drain current at TA = +70°C?
The DMT32M4LFG-7 supports 24A continuous drain current at ambient temperature +70°C, derated from 30A at +25°C per its thermal resistance (RθJA = 115°C/W on FR-4 with 2oz copper). This rating assumes standard PCB layout with thermal vias to inner ground layers.
Is this MOSFET qualified for automotive applications?
No - DMT32M4LFG-7 is not AEC-Q101 qualified. While it meets RoHS 3 and halogen-free requirements, Diodes specifies that automotive-grade variants require explicit PPAP documentation and IATF 16949 manufacturing - confirmed separately via part numbers suffixed with "-Q" or "-AQ".
How does the PowerDI3333-8 package improve thermal performance over SO-8?
PowerDI3333-8 achieves RθJC = 3.9°C/W versus ~6°C/W for SO-8 by using a larger exposed drain pad directly soldered to PCB copper, reducing thermal impedance by 35%. Its 33% smaller footprint also lowers parasitic inductance in high-di/dt paths.
Can this MOSFET be used in synchronous rectification with 3.3V gate drive?
Yes - with RDS(ON) = 2.8mΩ at VGS = 4.5V and gate threshold of 1–3V, it remains fully enhanced at 3.3V gate drive in most cases. However, actual on-resistance rises to ~3.5mΩ at 3.3V (per extrapolated transfer curves), increasing conduction loss by ~25% versus 4.5V drive.
