Product details
Overview
DMN3401LVQ-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SOT563 package, rated for 30V VDSS, 0.4Ω RDS(ON) at VGS = 10V, and 0.8A continuous drain current at TA = +25°C. It is AEC-Q101 qualified, PPAP-capable, and designed for automotive motor control, DC-DC converters, and backlighting power stages.
For engineers reviewing the DMN3401LVQ-13 datasheet, DMN3401LVQ-13 pinout, DMN3401LVQ-13 application, or DMN3401LVQ-13 equivalent, this part supports low-voltage logic-level drive (VGS(TH) = 0.8–1.6V), delivers fast switching (tF = 13.8ns), and maintains stable RDS(ON) across -55°C to +150°C junction temperature.
Technical Context
This dual N-channel MOSFET integrates two matched silicon die in a single SOT563 package with shared source terminals per channel, enabling half-bridge or load-switch configurations. Its gate threshold voltage range (0.8–1.6V) ensures reliable turn-on with 3.3V/5V microcontroller outputs.
The device features ESD-protected gates (±20V VGSS), low input capacitance (Ciss = 50pF), and thermally optimized construction for operation up to +150°C junction temperature. Its RDS(ON) increases only 1.6× from 25°C to 150°C at VGS = 10V, supporting robust thermal performance in automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Supports 24V automotive systems with margin against transients. |
| RDS(ON) @ VGS = 10V | 0.4Ω max - Enables <100mW conduction loss at 0.5A, critical for thermally constrained PCBs. |
| RDS(ON) @ VGS = 4.5V | 0.7Ω max - Ensures full enhancement with 3.3V logic drivers without external level-shifting. |
| ID Continuous @ TA = +25°C | 0.8A - Sufficient for LED backlight strings or small BLDC gate drivers in compact footprints. |
| Ciss | 50pF - Reduces gate drive power and enables >1MHz switching in DC-DC applications. |
| tF | 13.8ns - Minimizes switching losses during high-frequency PWM in motor control loops. |
| TJ Range | -55°C to +150°C - Validated for under-hood automotive use per AEC-Q101 stress testing. |

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 |
|---|---|---|---|
| DMN3025LFD-7 | Single-channel, 30V, 0.025Ω RDS(ON) @ 10V, SOT23-6 package | Higher current (3.8A), but lacks dual topology; requires two devices for same functionality | Select when higher efficiency at >1A load is needed and board area permits discrete layout. |
| DMN3029LFD-7 | Single-channel, 30V, 0.029Ω RDS(ON) @ 4.5V, SOT23-6 package | Better 4.5V RDS(ON) (0.029Ω vs. 0.7Ω), but no integrated dual structure or AEC-Q101 certification | Choose for non-automotive industrial DC-DC where lower on-resistance outweighs qualification needs. |
Compared with DMN3401LVQ-13, DMN3025LFD-7 offers 28× lower RDS(ON) but doubles component count and lacks AEC-Q101 validation; DMN3029LFD-7 improves low-VGS conduction but sacrifices automotive reliability assurance and dual integration.

FAQ
Is DMN3401LVQ-13 pin-compatible with other SOT563 dual MOSFETs?
No-DMN3401LVQ-13 uses a proprietary internal connection where Pins 1 and 4 are both sources (common-source dual configuration), unlike generic dual-N SOT563 parts with independent source pins. Substitution requires verification of schematic topology and layout routing.
What is the maximum safe operating frequency for DMN3401LVQ-13 in PWM applications?
Based on tF = 13.8ns and tR = 3.3ns, the device supports clean switching up to 5 MHz in low-duty-cycle applications. For continuous 50% duty-cycle operation, thermal limits constrain practical use to ≤1 MHz with adequate PCB copper area.
Does DMN3401LVQ-13 include intrinsic body diode protection for inductive flyback?
Yes-the MOSFET integrates a monolithic body diode with VSD = 0.7–1.2V at 0.1A and 150°C. It is rated for 0.9A continuous body diode current (IS) and supports freewheeling in motor and relay drive circuits without external diodes.
Can DMN3401LVQ-13 be used in hot-swap or inrush current limiting circuits?
Yes-its 0.8A continuous rating, 4.5A pulsed capability (IDM), and 30V VDSS allow controlled ramp-up of capacitive loads. Gate threshold stability over temperature (±0.2V from -55°C to +150°C) ensures predictable turn-on behavior during cold-start conditions.
