Product details
Overview
DMN6040SSDQ-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SO-8 package, rated for 60V VDS, 40mΩ RDS(ON) @ 10V VGS, and 5.0A continuous drain current at +25°C - designed for high-efficiency DC-DC converters and automotive-grade power management circuits.
For engineers reviewing the DMN6040SSDQ-13 datasheet, DMN6040SSDQ-13 pinout, DMN6040SSDQ-13 application, or DMN6040SSDQ-13 equivalent, key selection criteria include AEC-Q101 qualification, low gate charge (22.4nC @ 10V), body diode recovery performance (tRR = 18ns), and thermal resistance (RθJA = 75°C/W with enhanced layout).
Technical Context
This dual MOSFET integrates two matched N-channel silicon devices in a single SO-8 package with independent source, gate, and drain terminals per channel. Its design emphasizes low conduction loss and fast switching via optimized gate oxide thickness and trench cell structure.
The device supports synchronous rectification in buck converters and load-switching in automotive infotainment systems, leveraging its 4.5V-rated RDS(ON) of 55mΩ and 1.0–3.0V gate threshold range to ensure robust turn-on with standard logic-level drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60V - supports 48V bus and 36V automotive systems with margin against transients |
| RDS(ON) @ 10V | 40mΩ max - enables ≤200mW conduction loss at 5A, critical for thermally constrained PCBs |
| RDS(ON) @ 4.5V | 55mΩ max - ensures reliable operation with 3.3V/5V microcontroller GPIO drive |
| QG @ 10V | 22.4nC - reduces gate driver power demand and switching transition time in high-frequency SMPS |
| tRR | 18ns - minimizes reverse recovery losses and EMI in synchronous rectifier topologies |
| RθJA (enhanced layout) | 75°C/W - allows 1.7W continuous dissipation at +70°C ambient without heatsink |
| AEC-Q101 Qualified | Yes - validated for automotive power modules requiring extended temperature (-55°C to +150°C) and reliability |
Pinout & Package
Package: SO-8 (Surface-Mount, 8-pin, 4.9mm × 6.0mm footprint, 1.45mm height, RoHS-compliant green molding compound).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G1) | Gate of Channel 1 | High-impedance control input; requires <22.4nC charge for full turn-on |
| 2 (S1) | Source of Channel 1 | Reference node for Channel 1; tied to local ground or switch-node return path |
| 3 (D1) | Drain of Channel 1 | High-side or low-side power path connection; shares thermal pad with D2/S2 |
| 4 (D2) | Drain of Channel 2 | Independent high-current output; electrically isolated but thermally coupled to D1 |
| 5 (S2) | Source of Channel 2 | Separate return path for Channel 2; enables dual independent switching or paralleled operation |
| 6 (G2) | Gate of Channel 2 | Independent control terminal; identical drive requirements to G1 |
| 7,8 (Thermal Pad) | Exposed Drain Tie | Internally connected to both D1 and D2; must be soldered to PCB copper for thermal performance |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) @ 4.5V | 55mΩ max - enables direct drive from 3.3V/5V MCUs without level-shifting |

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 |
|---|---|---|---|
| DMN6040SSDQ-7 | Same die, identical specs; differs only in tape-and-reel packaging (1,000 pcs vs. 2,500 pcs) | No functional difference; selected for lower MOQ prototyping or small-batch production | Choose -7 for evaluation or pilot runs where volume does not justify full reel |
| NTMFS4C02PT1G | 60V, 3.8mΩ @ 10V, SO-8FL package; lower RDS(ON) but higher QG (34nC) and no AEC-Q101 rating | Better conduction loss but unsuitable for automotive due to qualification gap and larger gate drive requirement | Select only for industrial non-automotive designs where thermal margin exceeds 2× and qualification is not required |
Compared with DMN6040SSDQ-13, the -7 variant offers identical electrical performance with smaller reel size for flexibility, while NTMFS4C02PT1G trades AEC-Q101 compliance and gate drive efficiency for lower on-resistance - making the DMN6040SSDQ-13 optimal for cost-sensitive, qualified automotive power stages.

FAQ
What is the maximum continuous drain current for each channel at +70°C ambient?
The DMN6040SSDQ-13 supports 4.1A continuous drain current per channel at TA = +70°C with standard FR-4 PCB layout (Note 7). This derating reflects thermal limitations under steady-state conduction; using enhanced thermal pads increases capability to 5.3A at the same ambient.
Is the thermal pad (pins 7–8) internally connected to the drains?
Yes - pins 7 and 8 form a single exposed thermal pad internally bonded to both D1 and D2 drains. It must be soldered to a dedicated PCB copper pour tied to system ground or power plane to achieve the specified RθJA of 75°C/W.
Can this device be used in back-to-back configuration for bidirectional blocking?
Yes - the matched dual N-channel structure supports back-to-back connection for battery protection ICs. Each channel's body diode orientation allows symmetrical blocking of ±60V, provided gate drive maintains VGS > VGS(th) on both devices during conduction.
Does the 18ns body diode reverse recovery time apply under all operating conditions?
The 18ns tRR is measured at IS = 4.3A, di/dt = 100A/µs, and TJ = +25°C. Recovery time increases to ~25ns at +125°C junction temperature and decreases slightly at lower currents - design margins should account for worst-case thermal and current conditions.
