Product details
Overview
DMT6005LFG from Diodes Incorporated is a 60V N-channel enhancement-mode MOSFET in PowerDI3333-8 package, optimized for high-efficiency power conversion with RDS(ON) = 4.1 mΩ @ VGS = 10V, 100A continuous drain current at TC = +25°C, and 100% production-tested UIS robustness. It serves as a primary switching element in synchronous rectification stages of DC-DC converters.
For engineers reviewing the DMT6005LFG datasheet, DMT6005LFG pinout, DMT6005LFG application, or DMT6005LFG equivalent, key selection criteria include its low on-resistance at 4.5V gate drive (7 mΩ), thermally efficient exposed-drain package, and validated avalanche energy rating (EAS = 171 mJ) for inductive load reliability.
Technical Context
This MOSFET employs a trench-gate silicon process to achieve simultaneous low RDS(ON) and fast switching performance, with Ciss = 3150 pF and Qg = 48.7 nC at VGS = 10V. Its body diode exhibits tRR = 40.8 ns and QRR = 51.5 nC under IF = 30A, di/dt = 100 A/μs conditions.
The device is rated for operation from –55°C to +150°C junction temperature, with RθJC = 2.0°C/W enabling high-power dissipation when mounted on a thermally enhanced PCB pad. Gate threshold voltage VGS(TH) is specified 1–2.5 V, supporting TTL- and 3.3V-compatible gate drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - Maximum blocking voltage before avalanche conduction; suitable for 48V bus systems with margin. |
| RDS(ON) @ VGS = 10V | 4.1 mΩ - Enables <1W conduction loss at 50A, critical for high-current synchronous rectifiers. |
| ID Continuous @ TC = 25°C | 100 A - Limited by package thermal capability; requires proper copper pour and soldering to exposed drain pad. |
| EAS | 171 mJ - Confirmed single-pulse avalanche energy; supports reliable operation in inductive switching circuits without snubbers. |
| Qg @ VGS = 10V | 48.7 nC - Determines gate driver current requirement; enables efficient 500 kHz+ switching with moderate driver strength. |
| tRR / QRR | 40.8 ns / 51.5 nC - Low reverse recovery charge minimizes shoot-through risk and switching losses in synchronous buck topologies. |
| RθJC | 2.0°C/W - Thermal resistance from junction to case (exposed drain); enables direct heatsinking via PCB copper or external metal slug. |
Pinout & Package
Package: PowerDI® 3333-8 - Thermally enhanced 8-pin surface-mount package with exposed drain pad occupying only 33% board area vs. SO-8; UL 94V-0 molded plastic, matte tin annealed terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 8, 7, 6, 5 (Top View) | Drain (D), Source (S), Gate (G) | Pins 1–4 & 6–8: Parallel-connected drain terminals; Pin 5: Gate; Pin 6: Source - dual-source configuration reduces source inductance and improves switching stability. |
Key Features
| Feature | Design Value |
|---|---|
| 100% UIS tested in production | Guarantees minimum 171 mJ avalanche energy per unit, eliminating need for batch-level qualification testing in end applications. |
| Low RDS(ON) @ 4.5V | 7 mΩ enables use with 5V or 4.5V logic-level gate drivers without level-shifting, reducing BOM count in cost-sensitive motor drives. |
| PowerDI3333-8 footprint | 3.3 mm × 3.3 mm outline with exposed drain pad delivers 31× lower RθJC than SO-8, allowing >3× higher power density in space-constrained converters. |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets automotive and industrial environmental compliance requirements. |
Applications
| Synchronous Rectification in DC-DC Converters | Brushless DC Motor Control Stages |

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 |
|---|---|---|---|
| DMT6005LK3-13 | Same die, identical RDS(ON), Qg, and EAS; differs only in tape-and-reel packaging (3k vs. 2k units). | No functional difference; selected for volume procurement where 3k reels align with SMT line setup. | Drop-in replacement for DMT6005LFG-7 when reel quantity matches production batch size. |
| DMTH6005LPS-13 | Same RDS(ON) and voltage rating but in PowerFLAT™ 5x6 package; RθJC = 1.7°C/W (vs. 2.0°C/W); Qg = 52.5 nC (vs. 48.7 nC). | Better thermal performance but slightly slower switching; suited for thermally limited but less aggressive frequency designs. | Preferred when board layout allows larger 5x6 footprint and junction temperature margin is more critical than switching speed. |
Compared with DMT6005LFG-7, DMT6005LK3-13 offers identical electrical performance in a different reel size, while DMTH6005LPS-13 trades minor gate charge increase for improved thermal resistance-making it preferable in thermally constrained but lower-frequency applications.

FAQ
What is the maximum continuous drain current at TA = +70°C?
The DMT6005LFG supports 14 A continuous drain current at ambient temperature +70°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits imposed by FR-4 PCB mounting with 2 oz copper and 1-inch² thermal bias plate, not package limitation.
Does this MOSFET require a gate resistor for safe operation?
A gate resistor is recommended to control dV/dt and prevent oscillation during switching. With Qg = 48.7 nC and typical gate driver output impedance, a 3.3 Ω resistor achieves measured tR = 11.3 ns and tF = 11.0 ns, matching characterization conditions in the datasheet.
Is the PowerDI3333-8 package lead-free and RoHS compliant?
Yes, the DMT6005LFG features matte tin annealed terminals over copper leadframe and complies with EU RoHS directives 2011/65/EU and 2015/863/EU. It is also halogen- and antimony-free, meeting Diodes' "Green" definition with <900 ppm bromine/chlorine and <1000 ppm antimony.
Can this MOSFET be used in automotive applications?
While DMT6005LFG is not AEC-Q101 qualified, Diodes offers automotive-grade variants (e.g., DMT6005LFGQ) with PPAP support and IATF 16949 manufacturing. For non-safety-critical BCM or lighting loads, DMT6005LFG may be used subject to customer qualification per internal stress testing protocols.
