Product details
Overview
DMN3401LDWQ-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 automotive motor control, DC-DC converters, and power management functions under AEC-Q101 qualification.
For engineers reviewing the DMN3401LDWQ-7 datasheet, DMN3401LDWQ-7 pinout, DMN3401LDWQ-7 application, or DMN3401LDWQ-7 equivalent, key selection criteria include dual-channel low-RDS(ON) performance at 4.5V gate drive, fast switching (tF = 13.8ns), ESD-protected gate, and IATF16949-certified manufacturing for automotive-grade reliability.
Technical Context
This dual MOSFET integrates two independent N-channel devices with matched threshold voltage (0.8–1.6V) and body diodes, enabling synchronous rectification or half-bridge configurations without external diodes. Each channel supports ±20V gate-source voltage and exhibits low input capacitance (Ciss = 50pF) and gate charge (Qg = 1.2nC @ 10V).
Thermal design is constrained by RθJA = 360°C/W on FR-4 with 1-inch² copper pad, limiting steady-state power dissipation to 0.35W. The device operates across –55°C to +150°C junction temperature, with RDS(ON) increasing <2× over full range at VGS = 4.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - maximum blocking voltage per channel before avalanche conduction |
| RDS(ON) @ 10V | 0.4Ω - enables ≤0.32W conduction loss at 0.8A ID, critical for thermally constrained automotive PCBs |
| RDS(ON) @ 4.5V | 0.7Ω - ensures functional switching in 5V logic-driven systems like body control modules |
| Qg @ 10V | 1.2nC - reduces gate driver power demand and switching transition time in high-frequency DC-DC stages |
| tF | 13.8ns - minimizes overlap losses in synchronous buck converters operating >500kHz |
| Ciss | 50pF - lowers Miller effect and improves noise immunity in noisy automotive environments |
| TJ Range | –55°C to +150°C - validated operation across engine bay and cabin temperature extremes |
Pinout & Package
Package: SOT363 - surface-mount, 6-pin, dual-channel leadless plastic case with matte tin annealed terminals; moisture sensitivity level 1 per J-STD-020; weight ≈ 0.027g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S1) | Source of Q1 | Low-side return path for first MOSFET; internally connected to pin 2 (D1) via body diode |
| 2 (D1) | Drain of Q1 | High-side switching node for Q1; shares thermal pad with pin 3 (G1) |
| 3 (G1) | Gate of Q1 | ESD-protected control terminal; requires ≤±20V drive; 58Ω gate resistance limits ringing |
| 4 (S2) | Source of Q2 | Independent source node for second MOSFET; electrically isolated from S1 |
| 5 (D2) | Drain of Q2 | Second high-side switching node; symmetrical layout to D1 for balanced layout routing |
| 6 (G2) | Gate of Q2 | Separate gate input; identical electrical characteristics to G1 for matched dual-channel timing |
Key Features
| Feature | Design Value |
|---|---|
| Dual N-channel topology | Enables compact half-bridge or load-switch designs without discrete pairing or matching effort |

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 |
|---|---|---|---|
| DMN3029LSD-13 | Single-channel, 30V, 0.029Ω RDS(ON) @ 10V, SO-8 package | Higher current capacity (6.5A) but larger footprint and no integrated dual topology | Select when higher power density per channel is required and board space allows SO-8 layout |
| NTJD4152PZT5G | Dual N-channel, 30V, 0.22Ω RDS(ON) @ 4.5V, SOT-363, but not AEC-Q101 qualified | Lacks automotive qualification and PPAP support; lower RDS(ON) at 4.5V | Acceptable for non-automotive industrial or consumer DC-DC where qualification is not mandated |
Compared with DMN3401LDWQ-7, DMN3029LSD-13 offers higher current handling but sacrifices integration and automotive compliance, while NTJD4152PZT5G provides better low-voltage RDS(ON) but lacks AEC-Q101 validation - making DMN3401LDWQ-7 the only qualified dual-channel solution in SOT363 for automotive power switching.

FAQ
Is DMN3401LDWQ-7 suitable for hot-swap applications?
No - DMN3401LDWQ-7 lacks built-in current limiting, thermal shutdown, or slew-rate control required for safe hot-swap insertion. Its 0.8A continuous rating and absence of fault reporting make it unsuitable for live backplane or USB-C PD applications without external protection circuitry.
What is the maximum pulsed drain current rating?
The pulsed drain current (IDM) is rated at 4A for 10µs pulses with 1% duty cycle. This value assumes proper PCB thermal design (1-inch² copper pad) and is limited by bond wire integrity and transient thermal impedance, not steady-state power dissipation.
Does the device include internal gate protection diodes?
Yes - each channel includes an integrated gate protection diode between gate and source (G1–S1 and G2–S2), as confirmed by the top-view schematic in the datasheet. These diodes clamp ESD transients up to ±2kV HBM and prevent gate oxide breakdown during handling or system-level surges.
Can DMN3401LDWQ-7 be used in linear mode (ohmic region) operation?
Not recommended - the device is characterized and qualified for switching operation only. Safe Operating Area (SOA) curves show limited linear-mode capability (≤10ms pulse at 0.4A/10V), and thermal runaway risk increases above VGS = 4.5V due to positive RDS(ON) temperature coefficient.
