Product details
Overview
DMT47M2LDV-7 from Diodes Incorporated is a dual 40V N-channel enhancement-mode MOSFET in PowerDI3333-8 package, featuring 10.8mΩ RDS(ON) @ VGS=10V, 30.2A continuous drain current at TC=+25°C, and AEC-Q101 qualification for automotive-grade reliability-used in high-efficiency DC-DC converters and motor control stages.
For engineers reviewing the DMT47M2LDV-7 datasheet, DMT47M2LDV-7 pinout, DMT47M2LDV-7 application, or DMT47M2LDV-7 equivalent, key selection criteria include dual-channel RDS(ON) matching, 100% UIS-rated ruggedness, thermal resistance (RθJC = 8.43°C/W), and PowerDI3333-8 footprint compatibility with space-constrained power stages.
Technical Context
This dual N-channel MOSFET integrates two matched silicon die in a single exposed-drain PowerDI3333-8 package, enabling synchronous rectification or half-bridge configurations without external paralleling. Its low gate charge (Qg = 14.0nC @ 10V) and fast switching (tF = 8.53ns) support high-frequency operation up to 1MHz in buck converters.
The device's 100% unclamped inductive switching (UIS) rating (EAS = 24.4mJ, IAS = 22.1A) and -55°C to +150°C operating range ensure robust performance under transient overloads and automotive under-hood conditions-validated per AEC-Q101 stress test requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40V - Maximum blocking voltage for 12V/24V automotive and industrial DC bus applications |
| RDS(ON) @ 10V | 10.8mΩ - Enables ≤0.65W conduction loss at 25A, critical for thermally constrained PCB layouts |
| ID (TC=25°C) | 30.2A - Continuous current capability with heatsinked case mounting for high-power density designs |
| Qg @ 10V | 14.0nC - Low gate drive energy reduces controller IC loading and improves efficiency above 300kHz |
| RθJC | 8.43°C/W - Thermal path from junction to exposed drain pad enables direct copper pour cooling |
| tF | 8.53ns - Fast fall time minimizes switching overlap losses in synchronous rectifiers |
| AEC-Q101 | Qualified - Meets automotive reliability standards for temperature cycling, HTRB, and UIS testing |
Pinout & Package
Package: PowerDI3333-8 (Type UXC), surface-mount, thermally enhanced with exposed drain pad (D1/D2). Molded green compound, UL 94V-0 rated, 0.072g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (D1) | Drain 1 | High-current output node for Channel 1; electrically tied to exposed drain pad for thermal conduction |
| Pin 2 (S1) | Source 1 | Return path for Channel 1; referenced to ground or low-side switch node |
| Pin 3 (G1) | Gate 1 | Control input for Channel 1; requires <2.3V threshold and 14nC charge for full enhancement |
| Pin 4 (D2) | Drain 2 | Independent high-current output for Channel 2; isolated from D1 but shares thermal pad |
| Pin 5 (S2) | Source 2 | Separate return path for Channel 2; enables independent source referencing or floating configuration |
| Pin 6 (G2) | Gate 2 | Independent control input for Channel 2; matched threshold (1.2–2.3V) and drive requirements to G1 |
| Pads 7–8 | Exposed Drain (D1/D2) | Common thermal and electrical connection point for both drains; must be soldered to large copper area |
Key Features
| Feature | Design Value |
|---|---|
| Dual matched N-channel die | Ensures consistent RDS(ON), Qg, and timing between channels for balanced half-bridge operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT47M2LDVQ-7 | Identical silicon die and package, but AEC-Q101 certified with full automotive PPAP documentation | Required for production automotive ECUs; same electrical specs but traceable lot control and extended temp validation | Select when automotive OEM qualification or zero-defect supply chain requirements apply |
| DMTH4007LPS-13 | Single-channel 40V MOSFET in PowerDI5060, RDS(ON) = 7.5mΩ @ 10V, higher current (42A), no dual configuration | Suitable for discrete half-bridge builds where layout flexibility outweighs integration benefit | Choose when higher single-channel current or different thermal interface geometry is needed |
Compared with DMT47M2LDV-7, the DMT47M2LDVQ-7 adds automotive compliance overhead without electrical change, while DMTH4007LPS-13 trades dual integration for lower RDS(ON) and higher current-but requires two devices and larger board area for equivalent functionality.

FAQ
What is the maximum safe operating temperature for DMT47M2LDV-7?
The device has a specified junction temperature range of –55°C to +150°C. Its absolute maximum rating is TJ = +150°C, and thermal design must ensure this limit is not exceeded under worst-case ambient and power dissipation conditions. The RθJC = 8.43°C/W value applies only when the exposed drain pad is soldered to ≥1in² of 2oz copper on the PCB.
Can DMT47M2LDV-7 be used in a synchronous buck converter as both high-side and low-side switches?
No-DMT47M2LDV-7 contains two N-channel MOSFETs only, so it cannot function as a high-side switch without an external gate driver capable of bootstrap or isolated level-shifting. It is commonly used as dual low-side switches or as the low-side pair in a half-bridge with an external high-side P-channel or N-channel driver.
Is the PowerDI3333-8 package lead-free and RoHS compliant?
Yes-DMT47M2LDV-7 is fully RoHS compliant per EU Directive 2015/863/EU (RoHS 3), with matte tin annealed finish over copper leadframe and halogen/antimony-free green molding compound (<900ppm Br, <900ppm Cl, <1000ppm Sb).
How does the 100% UIS testing impact circuit design?
100% unclamped inductive switching testing means each unit is validated to survive single-pulse avalanche energy of 24.4mJ (IAS = 22.1A, L = 0.1mH) without parameter shift or failure. This eliminates the need for external clamping diodes or snubbers in relay driving, solenoid control, and motor commutation circuits.
