Product details
Overview
DMT47M2LDVQ-7 from Diodes Incorporated is a dual 40V N-channel enhancement-mode MOSFET in PowerDI3333-8 package, qualified to AEC-Q101 and PPAP-capable for automotive use. It delivers RDS(ON) = 10.8 mΩ @ VGS = 10 V, 30.2 A continuous drain current at TC = +25°C, and supports motor controls, DC-DC converters, and power-management functions.
For engineers reviewing the DMT47M2LDVQ-7 datasheet, DMT47M2LDVQ-7 pinout, DMT47M2LDVQ-7 application, or DMT47M2LDVQ-7 equivalent, key selection criteria include dual-channel layout, low RDS(ON) at 4.5 V and 10 V gate drive, AEC-Q101 qualification, thermal resistance (RθJC = 8.43°C/W), and unclamped inductive switching robustness.
Technical Context
This dual N-channel MOSFET integrates two independent 40 V, 30.2 A channels in a single PowerDI3333-8 package with shared thermal pad. Each channel features VGS(TH) = 1.2–2.3 V, low input capacitance (Ciss = 891 pF), and fast switching (tD(ON) = 3.95 ns, tF = 8.53 ns).
It supports high-efficiency synchronous rectification and half-bridge topologies in automotive power systems. The device's 100% production-tested UIS capability, normalized RDS(ON) stability over –55°C to +150°C, and body diode tRR = 56.6 ns enable reliable operation under transient load and thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40 V - Maximum blocking voltage per channel; suitable for 12 V/24 V automotive bus systems with margin. |
| RDS(ON) @ VGS = 10 V | 10.8 mΩ - Enables <1.2 W conduction loss at 30.2 A; critical for high-current motor driver stages. |
| RDS(ON) @ VGS = 4.5 V | 15 mΩ - Ensures robust turn-on with standard 5 V logic-level gate drivers in space-constrained modules. |
| ID Continuous @ TC = +25°C | 30.2 A - Dual-channel rating allows parallel operation without external current sharing components. |
| Qg @ VGS = 10 V | 14.0 nC - Low gate charge reduces driver power demand and enables >1 MHz switching in DC-DC controllers. |
| tRR (Body Diode) | 56.6 ns - Fast reverse recovery minimizes shoot-through risk and EMI in synchronous buck converters. |
| RθJC | 8.43°C/W - Efficient heat transfer to PCB copper pad supports compact thermal design in engine bay modules. |
Pinout & Package
Package: PowerDI3333-8 (Type UXC), surface-mount, thermally enhanced with exposed drain pad. Molded green compound (UL 94V-0), matte tin annealed terminals, MSL Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (D1) | Drain of Channel 1 | High-current output node; electrically tied to exposed thermal pad for low-inductance, low-resistance heat path. |
| Pin 2 (S1) | Source of Channel 1 | Reference node for gate drive; connects to low-side switch return or current-sense resistor. |
| Pin 3 (G1) | Gate of Channel 1 | CMOS-compatible control input; requires <14 nC charge for full enhancement at 10 V. |
| Pin 4 (D2) | Drain of Channel 2 | Independent high-current output; enables dual-phase or complementary switching without cross-coupling. |
| Pin 5 (S2) | Source of Channel 2 | Isolated source node; supports floating high-side configuration when used with level-shifted gate drive. |
| Pin 6 (G2) | Gate of Channel 2 | Separate control input; allows independent timing and dead-time management per channel. |
| Pads 7–8 (Exposed Drain) | Common Drain Thermal Pad | Primary thermal interface; must be soldered to ≥1 in² 2 oz copper plane for rated 14.8 W dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| 100% UIS tested in production | Guarantees avalanche energy handling (EAS = 24.4 mJ) without derating - eliminates need for external snubbers in motor phase-legs. |
| Low RDS(ON) at 4.5 V | 15 mΩ enables direct drive from microcontroller GPIO or low-voltage PMIC outputs - reduces BOM count in compact ECUs. |
| Fast body diode recovery | tRR = 56.6 ns and QRR = 40.0 nC minimize reverse-recovery losses and voltage spikes in synchronous rectifiers. |
| AEC-Q101 qualification & PPAP support | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD - required for Tier-1 power module designs. |
| Green, halogen-free construction | <900 ppm Br/Cl, <1000 ppm Sb - meets global automotive environmental mandates (e.g., ELV, RoHS 3) without performance trade-offs. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT47M2LPSQ-7 | Same die, PowerDI5060-8 package; RθJC = 3.5°C/W, higher PD = 30 W, but larger footprint and 3× higher Ciss (2700 pF). | Better thermal performance but slower switching; suited for lower-frequency (<200 kHz), high-power (>25 W) motor drives. | Select when thermal budget dominates over switching speed - e.g., radiator fan drivers where size is less constrained. |
| DMTH4007LPSQ-7 | 40 V, single-channel, PowerDI5060-8; RDS(ON) = 5.5 mΩ @ 10 V, but no second channel; Qg = 22 nC. | Higher current density per channel but lacks dual integration; requires two devices for same functionality. | Choose only if board area permits discrete duplication and higher peak efficiency justifies added component count and routing complexity. |
Compared with DMT47M2LDVQ-7, DMT47M2LPSQ-7 trades switching speed for superior thermal handling, while DMTH4007LPSQ-7 sacrifices integration and gate drive efficiency to achieve lower on-resistance - making the DMT47M2LDVQ-7 optimal for space- and efficiency-constrained dual-channel automotive power stages.

FAQ
What is the maximum junction temperature and how does it affect continuous current rating?
The DMT47M2LDVQ-7 has an operating junction temperature range of –55°C to +150°C. At TC = +100°C, its continuous drain current drops to 24.2 A due to thermal derating - confirmed by the RθJC = 8.43°C/W and PD = 14.8 W rating. This ensures safe operation in under-hood environments without active cooling.
Is the device suitable for synchronous rectification in a 48 V automotive buck converter?
Yes - its 56.6 ns body diode reverse-recovery time, 15 mΩ RDS(ON) at 4.5 V, and matched dual-channel structure make it ideal for synchronous rectification in 48 V-to-12 V converters. The low Qgd/Qgs ratio (2.52/1.04 nC) also supports clean zero-voltage switching transitions.
How is the PowerDI3333-8 package thermally optimized for automotive PCB layouts?
The PowerDI3333-8 uses an exposed drain pad soldered directly to a large copper area (≥1 in², 2 oz) on the PCB. Its RθJC = 8.43°C/W and low RθJA = 53.7°C/W (on FR-4) enable efficient heat extraction - validated for sustained 14.8 W dissipation at TC = +25°C without heatsinks.
Does the device support logic-level gate drive from a 3.3 V microcontroller?
No - the gate threshold voltage VGS(TH) is specified 1.2–2.3 V, but RDS(ON) rises sharply below 4.5 V (15 mΩ max). At 3.3 V, conduction losses exceed 3× the 10 V value. A dedicated gate driver or level shifter is required for reliable enhancement in automotive MCU interfaces.
