Product details
Overview
DMT3006LFDFQ-7 from Diodes Incorporated is an AEC-Q101 qualified N-channel enhancement-mode MOSFET designed for automotive power management. It delivers 14.1A continuous drain current at VGS = 10V, 7mΩ RDS(ON), 30V VDSS, and operates across –55°C to +150°C junction temperature-used in battery management systems and DC-DC converters.
For engineers reviewing the DMT3006LFDFQ-7 datasheet, DMT3006LFDFQ-7 pinout, DMT3006LFDFQ-7 application, or DMT3006LFDFQ-7 equivalent, key selection criteria include its U-DFN2020-6 package footprint (4mm²), low 1.3V typical gate threshold, fast switching (tR = 5.5ns), and IATF 16949 manufacturing compliance for automotive-grade reliability.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) and fast switching in high-efficiency synchronous rectification and load-switching topologies. Its gate threshold voltage (1.0–3.0V) enables direct drive from 3.3V and 5V controllers without level-shifting.
The device integrates a robust body diode with 19.3ns reverse recovery time and 8.6nC QRR, supporting high-frequency operation in buck converters and OR-ing circuits. Thermal design is enabled by RθJA = 60°C/W on 1-inch² copper and RθJC = 6.9°C/W for heatsink-coupled layouts.
Key Specifications

|---|---|
| VDSS | 30V - supports 24V automotive rail with 25% margin against transients |
| RDS(ON) @ 10V | 7mΩ max - enables <1W conduction loss at 12A in compact 2×2mm layout |
| ID (TA = 25°C) | 14.1A - sustains peak load currents in battery disconnect and pre-charge circuits |
| VGS(TH) | 1.0–3.0V - compatible with 3.3V microcontroller GPIOs for direct logic-level control |
| QG @ 10V | 8.4nC - minimizes gate drive power and enables >1MHz PWM operation |
| tR/tF | 5.5ns/4.6ns - reduces switching losses and EMI in high-frequency DC-DC stages |
| RθJA (enhanced pad) | 60°C/W - allows 2.1W power dissipation at ambient ≤70°C without heatsink |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT3006LSDQ-7 | Same die, SOT-23-6 package - larger 2.9mm × 2.8mm footprint, RθJA = 155°C/W | Suitable for prototyping or space-tolerant designs where thermal budget allows higher junction rise | Select when manual soldering or legacy PCB land patterns require SOT-23-6 compatibility |
| IPB012N03L3ATMA1 | 30V, 1.2mΩ @ 10V, TO-263-7 - 5× lower RDS(ON), but 10× larger footprint and 10g weight | Used in high-current (>60A) traction inverters where conduction loss dominates over size constraints | Select only when <1mΩ RDS(ON) is mandatory and board area/weight are secondary to efficiency |
Compared with DMT3006LSDQ-7, the DMT3006LFDFQ-7 saves 75% board area and improves thermal resistance by 61%; versus IPB012N03L3ATMA1, it trades 83% higher RDS(ON) for 95% smaller footprint and 99% lower mass-ideal for distributed power nodes in modern vehicle domains.

FAQ
What is the maximum continuous drain current at 100°C ambient?
At TA = 100°C with the recommended 1-inch² copper pad, the DMT3006LFDFQ-7 supports 7.2A continuous drain current. This is derived from its 2.1W power rating and 60°C/W thermal resistance, ensuring safe operation below the 150°C maximum junction temperature.
Does this MOSFET require a gate resistor for automotive 12V systems?
A 10Ω gate resistor is recommended for EMI suppression and ringing control when driven by standard automotive MCU GPIOs. The device's 1.6Ω intrinsic gate resistance and 8.4nC total gate charge make it compatible with low-power drivers without external level-shifting.
Can DMT3006LFDFQ-7 be used in paralleled configurations?
Yes-the device exhibits positive temperature coefficient for RDS(ON) above 25°C (Figure 6), enabling stable current sharing. Parallel operation requires matched gate drive paths and symmetrical PCB layout to avoid thermal imbalance and localized hot spots.
Is the body diode suitable for reverse polarity protection?
No-the body diode conducts from source to drain and cannot block reverse input voltage. For reverse polarity protection, the device must be placed in the high-side configuration with external Schottky or ideal diode controller, as its intrinsic diode lacks sufficient VR rating and speed for that function.
