Product details
Overview
DMT3006LFG-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in PowerDI3333-8 package, rated for 30V VDSS, 6 mΩ RDS(ON) @ 10V VGS, and 55.6A continuous drain current at TC = +25°C. It delivers low conduction loss and high switching efficiency for compact DC-DC converters and LED backlighting power stages.
For engineers reviewing the DMT3006LFG-7 datasheet, DMT3006LFG-7 pinout, DMT3006LFG-7 application, or DMT3006LFG-7 equivalent, key selection criteria include RDS(ON) at 4.5V (10 mΩ), QGD × RDS(ON) figure-of-merit, thermal resistance (RθJC = 4.5 °C/W), avalanche rating (EAS = 31 mJ), and board-area reduction versus SO-8.
Technical Context
This MOSFET employs trench-gate silicon technology optimized for high-current, low-voltage synchronous rectification and buck converter high-side/low-side switching. Its 30V breakdown voltage and 100% UIS-rated ruggedness support reliable operation under transient overvoltage conditions in automotive and industrial power rails.
The PowerDI3333-8 package integrates an exposed drain pad for direct thermal coupling to PCB copper, enabling 27.8W power dissipation at TC = +25°C. Gate charge parameters (QG = 16.7 nC @ 10V) and fast switching times (tF = 4.6 ns) are tuned for high-frequency (>1 MHz) DC-DC topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage for 12V/24V input rail applications |
| RDS(ON) @ 10V | 6 mΩ - Enables ≤335 mW conduction loss at 7A load in 5V output converters |
| RDS(ON) @ 4.5V | 10 mΩ - Supports logic-level gate drive in 3.3V-controller systems without level shifters |
| ID (continuous, TC=25°C) | 55.6 A - Sustains high-current output stages with minimal paralleling |
| EAS | 31 mJ - Confirmed single-pulse avalanche energy for robustness against inductive switching spikes |
| RθJC | 4.5 °C/W - Allows direct thermal path to heatsink or large copper pour for high-power density layouts |
| QGD | 3.5 nC - Low gate-drain charge minimizes Miller-induced switching delay and shoot-through risk |
Pinout & Package
Package: PowerDI3333-8 - thermally enhanced 8-pin surface-mount package with exposed drain pad (pins 1–4 and 5–8 are source/drain pairs; pin 3 is gate).

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT3006LSD-7 | Same die, SO-8 package - higher RθJA (62 °C/W vs. 54 °C/W) and larger footprint | Lacks PowerDI3333-8's board-area savings and thermal performance; suitable only where legacy SO-8 layout exists | Select when reusing existing SO-8 footprints and thermal budget allows ≥15% higher junction temperature rise |
| SiR870DP-T1-GE3 | 30V, 5.2 mΩ @ 10V, 60A, PowerPAK® SO-8 - lower RDS(ON) but no 4.5V characterization; QGD = 4.8 nC | Better conduction loss at 10V drive but less suited for 3.3V controllers; not 100% UIS rated | Prefer for fixed 10V gate drive and maximum efficiency; avoid where 4.5V compatibility or avalanche ruggedness is mandatory |
Compared with DMT3006LFG-7, DMT3006LSD-7 trades thermal and space efficiency for footprint compatibility, while SiR870DP-T1-GE3 improves RDS(ON) at the cost of 4.5V drive assurance and avalanche validation - making DMT3006LFG-7 optimal for compact, rugged, logic-level DC-DC designs.

FAQ
What is the maximum safe operating temperature for DMT3006LFG-7?
The device has a specified junction temperature range of –55°C to +150°C. Under continuous operation, the absolute maximum TJ is 150°C. With RθJC = 4.5 °C/W and 27.8W power dissipation at TC = 25°C, maintaining case temperature below 110°C ensures safe margin. PCB layout with ≥1-inch² 2oz copper on drain pad is required to achieve this.
Does DMT3006LFG-7 support 3.3V gate drive reliably?
Yes - its gate threshold voltage (VGS(TH)) is specified from 1.0V to 3.0V, and RDS(ON) is characterized at 4.5V (10 mΩ max). At 3.3V VGS, typical RDS(ON) is ~15 mΩ (per Figure 3), delivering usable performance in logic-level applications with moderate current requirements (≤8A continuous).
Is the PowerDI3333-8 package lead-free and RoHS compliant?
Yes - DMT3006LFG-7 features matte tin annealed over copper leadframe, fully compliant with EU RoHS directives 2002/95/EC, 2011/65/EU, and 2015/863/EU. It is also halogen- and antimony-free ("Green" per Diodes' definition: <900 ppm Br, <900 ppm Cl, <1000 ppm Sb).
How does the body diode performance compare to standard Schottky solutions?
The integrated body diode has VSD = 0.7–1.0V at 2A and tRR = 19.3 ns, offering faster recovery than general-purpose MOSFETs but higher forward drop than discrete Schottkys. It is suitable for synchronous rectification where gate control eliminates reverse recovery loss - not recommended as a standalone freewheeling diode in high-frequency, low-VF applications.
