Product details
Overview
DMT2004UFG-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in PowerDI3333-8 package, rated for 24V VDSS, 5.0mΩ RDS(ON) @ 10V VGS, and 70A continuous drain current at TC = +25°C. It serves as a high-current, low-loss power switch in synchronous rectification and DC-DC converter output stages.
For engineers reviewing the DMT2004UFG-7 datasheet, DMT2004UFG-7 pinout, DMT2004UFG-7 application, or DMT2004UFG-7 equivalent, key selection criteria include its 2.5V gate threshold enabling 3.3V logic drive, 100% UIS-rated ruggedness, and thermally optimized PowerDI3333-8 footprint delivering 54°C/W RθJA with thermal pad bias.
Technical Context
This MOSFET employs trench-gate silicon process to achieve sub-5mΩ on-resistance while maintaining fast switching performance: 3.9ns turn-on delay, 30.8ns turn-off delay, and 53.7nC total gate charge at 10V. Its body diode exhibits 0.65V forward voltage at 2A, supporting efficient freewheeling in buck converters.
The device is characterized for operation from –55°C to +150°C junction temperature, with RDS(ON) normalized to 1.0 at 25°C and rising to ~1.3× at 125°C under 4.5V gate drive - critical for thermal design in compact power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 24V - maximum blocking voltage for 5V/12V rail applications without derating |
| RDS(ON) | 5.0mΩ @ VGS = 10V - enables <1W conduction loss at 45A in high-current POL converters |
| ID (continuous) | 70A @ TC = +25°C - supports high-current single-phase output stages with external heatsinking |
| VGS(TH) | 0.55–1.45V - ensures reliable turn-on with 3.3V microcontroller GPIO or PWM controller outputs |
| Qg | 53.7nC @ VGS = 10V - determines gate driver power requirement and switching loss trade-off |
| RθJC | 3.5°C/W - enables direct thermal path to PCB copper pour or heatsink via exposed drain pad |
| EAS | 36mJ - specifies single-pulse avalanche energy handling for inductive load transients |

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 |
|---|---|---|---|
| DMT2004LSD-7 | Same die, SO-8 package - higher RθJA (62°C/W), larger footprint (5.0mm × 6.0mm) | Limited to lower-current (<40A) or forced-air-cooled designs due to thermal resistance | Select when legacy SO-8 layout reuse is required and thermal budget permits 20% higher conduction loss |
| DMTH2004LPS-13 | Same RDS(ON) spec but PowerFLAT 5×6 package - 2.5× larger area, 2.8°C/W RθJC | Better thermal performance but incompatible with space-constrained mobile PCBs | Prefer for industrial motor drives where 5×6mm footprint and superior heatsinking outweigh size penalty |
Compared with DMT2004UFG-7, DMT2004LSD-7 trades 33% board area for easier rework and lower assembly cost, while DMTH2004LPS-13 delivers 20% lower junction-to-case resistance at the expense of footprint - making DMT2004UFG-7 optimal for ultra-dense, thermally constrained DC-DC modules.

FAQ
What is the maximum allowable gate-source voltage for DMT2004UFG-7?
The absolute maximum VGS rating is ±12V per the datasheet's Maximum Ratings table. Exceeding this value risks permanent gate oxide damage. For reliable operation, gate drive should be limited to 10V for full enhancement and 0V to –5V for safe turn-off, with transient spikes clamped using Zener diodes if needed.
Does DMT2004UFG-7 require a gate resistor for typical 200–500kHz DC-DC operation?
Yes - a 2.2Ω to 4.7Ω series gate resistor is recommended to dampen ringing caused by 1.6Ω intrinsic gate resistance and PCB trace inductance. This controls dV/dt during switching, prevents false triggering, and balances switching speed against EMI generation in high-frequency buck converters.
Can DMT2004UFG-7 be used in linear mode (e.g., as a pass element)?
No - it is not characterized or rated for linear (ohmic) operation. The Safe Operating Area (SOA) curve shows only pulsed operation up to 10ms; sustained linear use would exceed thermal limits due to lack of SOA derating data and risk thermal runaway at VDS > 5V and ID > 10A.
How is the exposed drain pad on PowerDI3333-8 connected internally?
The drain pad is electrically and thermally connected to pins 5–8 (all four drain terminals) and forms the primary current and heat conduction path. It must be soldered to a minimum 100mm² copper pour with ≥4 thermal vias (0.3mm diameter) to inner ground/power planes to achieve the specified 54°C/W RθJA rating.
