Product details
Overview
DMT3006LDK-7 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET in V-DFN3030-8 (Type Q) package, optimized for high-efficiency power management with 6.5mΩ RDS(ON) @ 10VGS, 46.2A continuous drain current at TC = +25°C, and fast switching (tF = 4.6ns), used in DC-DC converters and LED backlighting circuits.
For engineers reviewing the DMT3006LDK-7 datasheet, DMT3006LDK-7 pinout, DMT3006LDK-7 application, or DMT3006LDK-7 equivalent, key selection criteria include low RDS(ON) at 4.5VGS (10mΩ), thermal resistance RθJC = 6°C/W, body diode recovery charge QRR = 8.6nC, and V-DFN3030-8 footprint compatibility with space-constrained PCB layouts.
Technical Context
This MOSFET employs trench-gate silicon technology to achieve ultra-low on-resistance while maintaining robust switching performance. Its gate threshold voltage (1.0–3.0V) supports direct drive from 3.3V and 5V logic, and its low input capacitance (Ciss = 1155pF) reduces driver losses in high-frequency operation.
The device integrates a low-forward-voltage body diode (VSD ≤ 1.0V @ 2A) with fast reverse recovery (tRR = 19.3ns), enabling efficient synchronous rectification and minimizing shoot-through risk in buck converter topologies. Thermal design is supported by a low junction-to-case resistance of 6°C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Maximum blocking voltage before avalanche; suitable for 24V rail systems with margin. |
| RDS(ON) @ 10VGS | 6.5mΩ max - Enables <1W conduction loss at 40A, critical for high-current power stages. |
| RDS(ON) @ 4.5VGS | 10mΩ max - Ensures full enhancement with standard 3.3V/5V controllers without level-shifting. |
| Qg @ 10VGS | 16.7nC - Determines gate drive energy; enables efficient 1MHz+ switching with moderate driver strength. |
| tF | 4.6ns - Fast fall time minimizes switching transition losses in hard-switched topologies. |
| RθJC | 6°C/W - Allows direct thermal coupling to PCB copper pour or heatsink for high-power density designs. |
| QRR | 8.6nC - Low reverse recovery charge reduces EMI and cross-conduction losses in synchronous rectifiers. |
Pinout & Package
Package: V-DFN3030-8 (Type Q), 3.0mm × 3.0mm × 0.8mm, exposed drain pad (Pin 1–3, 5–8 = Source; Pin 4 = Gate; Pin 6 = Drain), RoHS-compliant NiPdAu-plated terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,2,3,5,6,7,8 | Source (S) | Common source connection; pins 1–3 and 5–8 are internally tied to source; pin 6 is also drain-requires careful layout to avoid shorting. |
| 4 | Gate (G) | Control terminal; low input capacitance (Ciss = 1155pF) eases drive requirements from microcontroller GPIO or dedicated gate drivers. |
| 6 (exposed pad) | Drain (D) | Main power output node; thermally coupled to PCB via exposed copper pad-must be connected to high-current drain net and thermal plane. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at 4.5VGS | 10mΩ max enables use with 3.3V logic-level controllers without external level shifters. |
| Fast switching speed | tF = 4.6ns and tD(OFF) = 13.5ns support >1MHz PWM in compact DC-DC converters. |
| Low QRR body diode | 8.6nC reverse recovery charge reduces switching losses and EMI in synchronous rectifier applications. |
| Thermally enhanced package | RθJC = 6°C/W allows >2.8W dissipation when mounted on 2oz copper thermal pad per datasheet note 6. |
| Green, halogen-free construction | <900ppm Br/Cl and <1000ppm Sb meets automotive and industrial environmental compliance mandates. |
Applications
| LED Backlighting | Point-of-Load DC-DC Converter |
|---|---|
|
Use Scenario: Driving white LED strings in LCD displays using constant-current buck topology. IC Role / Device Role / Timing Role: High-side switch controlling LED current path; operates at 200–500kHz PWM frequency. Use Value: Low RDS(ON) (6.5mΩ) minimizes power loss in high-current paths; fast tF ensures clean dimming transitions without visible flicker. |

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 |
|---|---|---|---|
| DMT3006LPS-7 | Same die, but in PSOF-8 package (leadless SO-8); RθJA = 50°C/W vs. 44°C/W for DMT3006LDK-7; no exposed drain pad. | Lacks thermal pad; unsuitable for >2W continuous dissipation without large copper area. | Select DMT3006LPS-7 only if legacy SO-8 footprint compatibility is required and thermal budget permits higher junction temperature. |
| SiR872DP-T1-GE3 | 30V, 5.2mΩ @ 10VGS, but larger PowerPAK® 1212-8 package; Qg = 22.5nC; RθJC = 3.2°C/W. | Higher thermal performance but 1212 footprint incompatible with 3030 layout; requires PCB redesign. | Choose SiR872DP-T1-GE3 only when >3W power handling is needed and board space allows larger package. |
Compared with DMT3006LDK-7, DMT3006LPS-7 trades thermal efficiency for SO-8 compatibility, while SiR872DP-T1-GE3 delivers superior thermal capability at the cost of footprint size and gate drive energy-making DMT3006LDK-7 optimal for space-constrained, medium-power DC-DC and backlighting designs.

FAQ
What is the maximum continuous drain current for DMT3006LDK-7 at 70°C case temperature?
The datasheet specifies 37.0A continuous drain current at TC = +70°C with VGS = 10V. This derating reflects thermal limitations of the V-DFN3030-8 package under real-world PCB thermal conditions, not ambient temperature alone. Designers must verify actual case temperature using thermal simulation or measurement under load.
Does DMT3006LDK-7 support 3.3V gate drive in practice?
Yes-its gate threshold voltage range is 1.0–3.0V, and RDS(ON) is guaranteed at 4.5VGS (10mΩ max). While full enhancement occurs above ~2.5V, reliable switching at 3.3V is confirmed by typical transfer curves showing >20A ID at VGS = 3.3V and VDS = 5V, making it compatible with standard 3.3V logic outputs.
How is the exposed drain pad on the bottom side electrically connected?
The exposed pad (Pin 6) is internally connected to the drain terminal only. It is not tied to source or gate. PCB layout must isolate this pad from all other nets except the main drain power net and thermal plane. Solder mask opening and thermal vias to inner-layer copper are required per Diodes' recommended pad layout for optimal thermal and electrical performance.
Is DMT3006LDK-7 suitable for avalanche-rated applications?
Yes-the datasheet specifies IAS = 25A and EAS = 31mJ under defined test conditions (L = 0.1mH, single-pulse). These ratings apply to unclamped inductive switching events, such as motor freewheeling or relay coil snubbing. However, repeated avalanche operation is not recommended; proper snubber design or clamping remains essential for long-term reliability.
