Product details
Overview
DMN3401LDWQ-13 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 automotive motor control and DC-DC converter power stages.
For engineers reviewing the DMN3401LDWQ-13 datasheet, DMN3401LDWQ-13 pinout, DMN3401LDWQ-13 application, or DMN3401LDWQ-13 equivalent, key selection criteria include AEC-Q101 qualification, low gate charge (1.2 nC @ 10V), fast switching (tF = 13.8 ns), thermal resistance (RθJA = 360°C/W on 1-in² copper), and dual-channel integration in a 6-pin SOT363 footprint.
Technical Context
This dual MOSFET integrates two independent N-channel devices with ESD-protected gates and integrated body diodes. Each channel supports 30V blocking, operates down to -55°C, and delivers stable RDS(ON) across temperature (±20% variation from -55°C to +150°C at VGS = 10V).
It employs planar trench-gate technology optimized for low input capacitance (Ciss = 50 pF) and fast turn-on/turn-off timing (tD(ON) = 3.5 ns, tD(OFF) = 16.8 ns), enabling high-frequency operation in automotive power management circuits without external gate drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum drain-source voltage before avalanche breakdown; enables use in 24V automotive systems with margin. |
| RDS(ON) @ 10V | 0.4 Ω max - Low conduction loss at nominal gate drive; supports ≤0.32 W I²R loss at 0.8A DC. |
| RDS(ON) @ 4.5V | 0.7 Ω max - Ensures usable on-resistance with 3.3V/5V logic-level gate drive in low-voltage control circuits. |
| Qg @ 10V | 1.2 nC - Low total gate charge reduces driver power demand and switching energy loss in PWM applications. |
| tF | 13.8 ns - Fast fall time minimizes overlap conduction loss during synchronous rectification in DC-DC converters. |
| RθJA | 360 °C/W - Thermal resistance on 1-in² copper; defines maximum power dissipation (0.35 W) under steady-state PCB layout. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥2 kV). |

| 2 (Q1 Gate) | Gate terminal of first MOSFET | Control input for Q1; requires <±20V rating and ESD protection compatible with microcontroller GPIO. |
| 3 (Q2 Drain) | Drain terminal of second MOSFET | High-side switching node for Q2; connects to load or inductive flyback path in H-bridge topologies. |
| 4 (Q2 Source) | Source terminal of second MOSFET | Common source for Q2; may be floating or referenced to bootstrap supply in high-side drive applications. |
| 5 (Q2 Gate) | Gate terminal of second MOSFET | Independent control input for Q2; enables asynchronous or complementary PWM control of dual channels. |
| 6 (Q1 Drain) | Drain terminal of first MOSFET | Primary output node for Q1; used for low-side switching, current sensing, or synchronous rectification. |
Key Features
| Feature | Design Value |
|---|---|
| Dual N-channel topology | Two matched MOSFETs in one SOT363 package reduce board area by >40% vs. discrete solutions and improve channel-to-channel timing matching. |
| Low RDS(ON) @ 4.5V | 0.7 Ω max enables direct interface with 3.3V/5V MCUs without level-shifting, simplifying gate drive design in space-constrained modules. |
| ESD-protected gate | HBM rating ≥2 kV per AEC-Q101 ensures robustness against handling and system-level ESD events in automotive assembly and field environments. |
| Fast switching speed | Combined tD(ON) + tR + tD(OFF) + tF < 38 ns supports >1 MHz PWM operation in buck converters with minimal dead-time overhead. |

| Automotive Power Management | LED Driver Current Switching |
Use Scenario: Load switching for battery-powered subsystems such as telematics gateways and body control modules. IC Role / Device Role / Timing Role: Dual-channel protected load switch providing reverse polarity, overcurrent, and thermal shutdown functions via external circuitry. Use Value: AEC-Q101 qualification and -55°C to +150°C operation ensure reliability in under-hood environments; 0.4Ω RDS(ON) limits voltage drop to <320 mV at 0.8A. | Use Scenario: Constant-current switching for interior ambient lighting and dashboard backlighting using PWM dimming. IC Role / Device Role / Timing Role: Low-side current sink controlling LED strings up to 300 mA per channel with precise duty-cycle modulation.

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 | Higher RDS(ON) (2.5Ω @ 4.5V), single-channel SOT23-6, lower ID (0.25A) | Not suitable for motor control or >200mA loads; limited to signal switching or low-power bias networks | Select only if space constraints prohibit SOT363 and current demand is <250mA per channel. |
| NTJD4152PT1G | Lower VDSS (20V), higher RDS(ON) (0.85Ω @ 4.5V), same SOT363 package | Restricted to 12V systems; unsuitable for 24V automotive rails or transient overvoltage conditions | Choose only for cost-sensitive 12V consumer applications where 30V margin is unnecessary. |
Compared with DMN3401LDWQ-13, DMN3025LSD-13 sacrifices current capability and dual functionality for smaller footprint, while NTJD4152PT1G trades voltage rating and on-resistance for broader distributor availability - neither matches the AEC-Q101-compliant 30V/0.7Ω@4.5V performance envelope required for modern automotive power stages.

FAQ
Is DMN3401LDWQ-13 qualified for automotive applications?
Yes. The DMN3401LDWQ-13 is fully AEC-Q101 qualified, manufactured in IATF 16949:2016-certified facilities, and supported by PPAP documentation. It undergoes stress testing including HTGB, HTRB, temperature cycling, and ESD (HBM ≥2 kV), meeting automotive reliability standards for under-hood and cabin applications.
What is the maximum continuous drain current per channel at +70°C?
The maximum continuous drain current per channel is 0.6 A at TA = +70°C, derated from 0.8 A at +25°C per the datasheet's thermal characteristics table (Note 6). This reflects junction-to-ambient thermal limits on standard FR-4 PCB with 1-inch square copper pour.
Can DMN3401LDWQ-13 be used in high-side switching configurations?
Yes - each channel operates independently, and Q2 can function as a high-side switch when its source is connected to a bootstrap or floating supply. However, no internal level-shifter is included; external gate drive circuitry must provide VGS ≥4.5V relative to the source node to achieve specified RDS(ON).
Does DMN3401LDWQ-13 include integrated gate protection diodes?
Yes. The device integrates gate protection diodes for both channels, as shown in the top-view pinout diagram (D1 and D2). These clamp transient overvoltage on the gate terminals, supporting robust operation in noisy automotive environments without external TVS components.
