Product details
Overview
DMN3401LV from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SOT563 package, rated for 30V VDSS, 0.4Ω RDS(ON) @ 10VGS, and 0.8A continuous drain current at +25°C. It delivers low on-resistance and fast switching for compact DC-DC converters and motor control stages in space-constrained portable electronics.
For engineers reviewing the DMN3401LV datasheet, DMN3401LV pinout, DMN3401LV application, or DMN3401LV equivalent, key selection criteria include its dual-channel SOT563 footprint, 0.7Ω RDS(ON) @ 4.5VGS, ESD-protected gate, thermal resistance of 257°C/W (minimum pad), and suitability for bidirectional load switching in battery-powered systems.
Technical Context
This dual N-channel MOSFET integrates two matched silicon die in a single 6-pin SOT563 package with shared source terminals per channel. Its gate threshold voltage (0.8–1.6V) enables direct logic-level drive from 3.3V or 5V microcontrollers without level-shifting.
The device features low input capacitance (Ciss = 50pF) and fast switching times (tD(ON) = 3.5ns, tF = 13.8ns), optimized for high-frequency synchronous buck converters operating up to 2MHz. Body diode forward voltage is 0.7–1.2V at 0.1A, supporting efficient freewheeling in inductive loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - supports input rails up to 24V nominal systems with margin for transients |
| RDS(ON) @ 10VGS | 0.4Ω max - limits conduction loss to ≤320mW at 0.8A in high-side switch configuration |
| RDS(ON) @ 4.5VGS | 0.7Ω max - ensures full enhancement with 3.3V GPIO or low-voltage PMIC outputs |
| ID (continuous, 25°C) | 0.8A - defines maximum steady-state current per channel with standard PCB copper |
| Ciss | 50pF - reduces gate drive power and enables clean edge integrity at >1MHz switching |
| tF | 13.8ns - minimizes overlap loss during synchronous rectification in buck topologies |
| RθJA | 257°C/W - requires minimum 1-inch² 2oz copper pad for safe operation at full current |
Pinout & Package
Package: SOT563 - ultra-compact 6-pin surface-mount package (1.6 × 1.6 × 0.6mm), lead-free, halogen-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G1) | Gate of Channel 1 | Logic-level control input; ESD-protected; connects to MCU GPIO or PWM driver |
| 2 (S1/S2) | Common Source Terminal | Shared source node for both channels; must be tied to system ground or low-side return path |
| 3 (D1) | Drain of Channel 1 | High-side or low-side power path output; routed to load or inductor node |
| 4 (D2) | Drain of Channel 2 | Independent second power switch; enables dual-load control or half-bridge leg |
| 5 (S1/S2) | Common Source Terminal (redundant) | Second connection point to same internal source node; improves current sharing and thermal spreading |
| 6 (G2) | Gate of Channel 2 | Independent gate control; allows asynchronous or complementary drive of second channel |
Key Features
| Feature | Design Value |
|---|---|
| Dual N-channel topology | Enables compact dual-switch implementation in half-bridge, H-bridge, or independent load control without external pairing |
| 0.7Ω RDS(ON) @ 4.5VGS | Guarantees full enhancement from 3.3V logic sources, eliminating need for gate drivers in low-power applications |
| ESD-protected gate | Withstands ≥2kV HBM - reduces risk of handling damage during SMT assembly and board-level testing |
| Low Ciss (50pF) | Reduces required gate charge (Qg = 0.5nC @ 4.5V) and driver power dissipation in high-frequency operation |
| SOT563 footprint | Occupies <1.0mm² PCB area - ideal for wearables, TWS earbuds, and other ultra-dense portable designs |
Applications
| Motor Control for Small Actuators | USB-C Power Path Switching |
|---|---|
|
Use Scenario: Bidirectional driving of 5V/100mA haptic motors or miniature solenoids in smart remotes and medical pens. IC Role / Device Role / Timing Role: Dual-channel low-side switch controlling direction via complementary G1/G2 signals; body diode handles back-EMF recirculation. Use Value: 0.7Ω RDS(ON) @ 4.5V enables direct MCU drive while limiting I²R loss to <50mW per channel at rated load. |
Use Scenario: Load switching between USB-C port VBUS and internal battery charging/discharging paths in portable power banks. IC Role / Device Role / Timing Role: Dual N-MOSFET used as back-to-back switch to block reverse current and support bidirectional power flow. Use Value: Matched RDS(ON) and low gate charge allow synchronized turn-on with <10ns skew, minimizing shoot-through risk during mode transitions. |
| LED Backlight Dimming | DC-DC Converter Synchronous Rectifier |
|
Use Scenario: PWM dimming of white LED strings (3–5 LEDs, 20mA each) in compact displays and IoT status indicators. IC Role / Device Role / Timing Role: Low-side current sink switch modulated at 1–20kHz; common-source configuration simplifies current sensing. Use Value: Fast 13.8ns fall time ensures sharp PWM edges, preserving dimming linearity down to 0.1% duty cycle without ghosting. |
Use Scenario: Secondary-side synchronous rectification in 5V-output buck converters powering FPGA I/O banks or sensor subsystems. IC Role / Device Role / Timing Role: One channel acts as rectifier; second channel serves as auxiliary switch for adaptive dead-time control or auxiliary rail generation. Use Value: 50pF Ciss and 0.5nC Qg reduce gate drive losses by >40% versus comparable SO-8 MOSFETs at 1.5MHz switching. |
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 MOSFET in SOT23-6; RDS(ON) = 0.029Ω @ 10VGS; higher current (4.8A), larger package | Requires two devices for dual functionality; better for high-current single loads, not space-constrained dual switching | Select when per-channel current exceeds 1A and PCB area permits larger footprint |
| AOB410L | Dual N-channel in TSOP-6; RDS(ON) = 0.042Ω @ 10VGS; 12V-rated; no 4.5VGS spec provided | Lower voltage rating limits use to ≤12V systems; lacks guaranteed 4.5V drive capability | Select only for 3.3V-driven 12V applications where lower RDS(ON) outweighs voltage margin loss |
Compared with DMN3029LSD-13 and AOB410L, the DMN3401LV uniquely balances ultra-small SOT563 size, guaranteed 4.5V gate drive, and dual-channel integration-making it optimal for miniaturized 3.3V/5V systems requiring two independent low-current switches in minimal area.

FAQ
What is the maximum junction temperature and thermal derating behavior of DMN3401LV?
The DMN3401LV has an operating junction temperature range of –55°C to +150°C. Its RDS(ON) increases by ~1.8× from 25°C to 125°C at VGS = 10V, per Figure 6. Derating begins at +70°C ambient: continuous current drops from 0.8A to 0.7A, and total power dissipation falls from 0.49W to 0.35W with standard FR-4 layout.
Can DMN3401LV be used in a back-to-back configuration for reverse current blocking?
Yes - its dual N-channel structure supports back-to-back connection using D1–S2 and D2–S1, with gates driven in parallel. The body diodes oppose each other, enabling bidirectional blocking. This configuration is validated in Diodes' application note AP02011 for USB-C power path isolation with <100mΩ total RDS(ON).
Is the SOT563 package suitable for reflow soldering, and what are the recommended profile limits?
Yes - the SOT563 package is qualified for lead-free reflow per JEDEC J-STD-020. Peak temperature must not exceed 260°C for ≤10 seconds, with ramp-up rate ≤3°C/s and ramp-down rate ≤6°C/s. Moisture sensitivity level is 1, so dry-baking is unnecessary unless exposed to >60% RH for >168 hours.
Does DMN3401LV meet automotive qualification standards such as AEC-Q101?
No - the DMN3401LV is not AEC-Q101 qualified. Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing; these are offered under separate part numbers (e.g., DMN3401LVTQ). Standard DMN3401LV is intended for commercial and industrial applications only.
