Product details
Overview
DMN3401LDW-7 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SOT363 package, rated for 30V VDSS, 0.4Ω RDS(ON) @ 10V VGS, and 0.8A continuous drain current at +25°C - designed for compact, high-efficiency DC-DC converters and motor control stages where low gate charge (1.2nC) and fast switching (tF = 13.8ns) reduce conduction and switching losses.
For engineers reviewing the DMN3401LDW-7 datasheet, DMN3401LDW-7 pinout, DMN3401LDW-7 application, or DMN3401LDW-7 equivalent, this page delivers verified electrical parameters, validated SOT363 terminal mapping, thermal derating guidance, and real-world substitution options with documented RDS(ON) and Qg trade-offs for power stage optimization.
Technical Context
This dual MOSFET integrates two matched N-channel devices sharing a common source configuration in a single SOT363 package, enabling half-bridge or synchronous rectifier topologies without discrete layout coupling. Its 0.7Ω RDS(ON) @ 4.5V VGS supports 3.3V logic-level drive, while ESD-protected gates tolerate ±20V VGS transients.
Thermal performance is defined by RθJA = 433°C/W (min pad) and 360°C/W (1-inch copper), with junction temperature range from –55°C to +150°C. Dynamic characteristics include Ciss = 50pF and Crss = 10pF, supporting MHz-range switching in space-constrained buck regulators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Maximum blocking voltage for 5V/3.3V-input DC-DC stages operating up to 24V rail |
| RDS(ON) @ 10V | 0.4Ω - Enables ≤0.32W conduction loss at 0.8A, critical for thermally limited PCBs |
| RDS(ON) @ 4.5V | 0.7Ω - Ensures turn-on with standard microcontroller GPIO without level-shifting |
| Qg @ 10V | 1.2nC - Reduces gate driver power demand and switching transition time in high-frequency designs |
| tF | 13.8ns - Limits shoot-through risk in synchronous rectification when paired with matched P-channel |
| PD (max) | 0.35W - Defines absolute thermal limit on 2oz FR-4 with 1-inch copper pour; derates to 0.29W on minimal pads |

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 |
|---|---|---|---|
| DMN3025LSD-13 | Lower RDS(ON) (0.25Ω @ 10V) but higher Qg (2.8nC); SOT23-6 package | Better conduction loss at high current (>1A), but slower switching increases losses above 1MHz | Prefer for <500kHz, high-current loads where thermal margin exceeds 0.5W |
| SI2302DS-T1-GE3 | Higher RDS(ON) (0.085Ω @ 4.5V) but lower VDSS (20V); same SOT363 footprint | Optimized for 3.3V-only systems; unsuitable for 24V input rails due to 20V rating | Select only for 3.3V/5V logic-level applications with strict size constraints and no 24V transients |
Compared with DMN3401LDW-7, DMN3025LSD-13 trades faster switching for lower conduction loss, while SI2302DS-T1-GE3 sacrifices voltage headroom for superior 3.3V drive efficiency - making DMN3401LDW-7 the balanced choice for 30V-tolerant, 1MHz-class DC-DC and motor control.

FAQ
What is the maximum continuous drain current for DMN3401LDW-7 at +70°C ambient?
The maximum continuous drain current is 0.6A at TA = +70°C, as specified in the Absolute Maximum Ratings table. This reflects thermal derating from the +25°C rating of 0.8A, based on RθJA = 433°C/W and 150°C max junction temperature. Operation above this requires forced airflow or enhanced copper pour.
Can DMN3401LDW-7 be used in a synchronous buck converter's high-side position?
No - DMN3401LDW-7 is a dual N-channel device with common-source configuration and no integrated bootstrap circuitry. It is intended for low-side switching or synchronous rectification. High-side N-channel use requires external gate-drive voltage boosting, which this part does not support.
Is the SOT363 package lead-free and RoHS compliant?
Yes - DMN3401LDW-7 uses matte tin annealed over copper leadframe, fully compliant with EU RoHS 2011/65/EU and RoHS 3 2015/863/EU directives. It contains no purposely added lead, and is halogen- and antimony-free per Diodes' "Green" definition (<900ppm Br/Cl, <1000ppm Sb).
What is the gate threshold voltage range, and how does it vary with temperature?
VGS(TH) ranges from 0.8V to 1.6V at +25°C (typical 1.2V), and decreases linearly to ~0.6V at +150°C, as shown in Figure 8. This negative temperature coefficient ensures stable turn-on behavior across industrial temperature ranges without external bias adjustment.
