Product details
Overview
DMC3401LDW-13 from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in a single SOT363 package, integrating one N-channel (30 V, 0.4 Ω @ 10 V) and one P-channel (−30 V, 0.9 Ω @ −10 V) device for half-bridge or level-shifting power control. It delivers 0.8 A continuous drain current (Q1) and −0.55 A (Q2) at +25°C, with ESD-protected gates and fast switching (tF = 13.8 ns / 31 ns), enabling compact DC-DC converters and motor drive stages.
For engineers reviewing the DMC3401LDW-13 datasheet, DMC3401LDW-13 pinout, DMC3401LDW-13 application, or DMC3401LDW-13 equivalent, key selection criteria include dual-channel RDS(ON) matching at low gate drive (4.5 V/−4.5 V), thermal resistance (RθJA = 301 °C/W with copper pad), and SOT363 footprint compatibility with space-constrained PCB layouts.
Technical Context
This dual MOSFET implements complementary switching in a monolithic SOT363 package, where Q1 (N-channel) and Q2 (P-channel) share no internal connection-each channel operates independently with separate gate, drain, and source terminals. The design supports bidirectional current control and synchronous rectification without cross-conduction risk when driven with proper dead-time sequencing.
Gate protection diodes are integrated per channel to suppress transient overvoltage, and both devices meet ±20 V gate-source voltage rating with threshold voltages of 0.8–1.6 V (Q1) and −1.0 to −2.6 V (Q2), enabling reliable turn-on from standard 3.3 V or 5 V logic-level drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V (Q1), −30 V (Q2): Supports 24 V rail systems with 20 % headroom for transients. |
| RDS(ON) | 0.4 Ω @ 10 V (Q1), 0.9 Ω @ −10 V (Q2): Enables <120 mW conduction loss at 0.6 A load. |
| ID Continuous | 0.8 A (Q1), −0.55 A (Q2) at +25°C: Sufficient for low-power motor gate drivers or load switches. |
| Ciss | 50 pF (Q1), 19 pF (Q2): Low input capacitance reduces gate drive power and speeds up edge transitions. |
| tF | 13.8 ns (Q1), 31 ns (Q2): Fast fall time minimizes switching overlap loss in PWM-controlled topologies. |
| RθJA | 301 °C/W (with 1-inch² copper pad): Limits junction rise to ~90°C at 0.29 W dissipation in typical layout. |
| ESD Rating | HBM >2 kV: Integrated gate protection eliminates need for external TVS in non-automotive environments. |
Pinout & Package
Package: SOT363 - 6-pin surface-mount plastic package (2.15 mm × 2.10 mm × 0.95 mm), lead-free, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G1) | N-channel gate | Control input for Q1; accepts 0–10 V logic; protected by integrated Zener clamp. |
| 2 (D1) | N-channel drain | High-side switch node; connects to supply rail in high-side configuration or output in low-side. |
| 3 (S1) | N-channel source | Reference node for Q1; tied to ground in low-side or floating in half-bridge configurations. |
| 4 (S2) | P-channel source | Reference node for Q2; typically connected to VOUT or switched rail in level-shifted drivers. |
| 5 (D2) | P-channel drain | Low-side switch node; sinks current to ground or returns to input in buck converter sync rectifier. |
| 6 (G2) | P-channel gate | Control input for Q2; driven negative relative to S2; threshold centered at −2.2 V. |
Key Features
| Feature | Design Value |
|---|---|
| Complementary dual-channel integration | Single SOT363 footprint replaces discrete N+P pair, saving ≥30 % board area in H-bridge or load-switch designs. |
| Logic-level gate drive support | RDS(ON) = 0.7 Ω (Q1) and 1.7 Ω (Q2) at 4.5 V/−4.5 V enables direct MCU GPIO control without level shifters. |
| Low dynamic losses | Qg = 1.2 nC (Q1) and 0.8 nC (Q2) at rated VGS reduce driver power and EMI in 500 kHz–1 MHz DC-DC stages. |
| Thermally robust construction | Molded "Green" compound (UL 94V-0) and matte tin finish ensure solderability and long-term reliability under thermal cycling. |
| Automotive-ready qualification path | Manufactured in IATF 16949-certified facilities; AEC-Q101 qualification available upon request for automotive power modules. |
Applications
| Brushless DC Motor Driver Stage | USB-C Power Delivery Load Switch |
|---|---|

Use Value: Independent gate control allows precise timing of body diode conduction and MOSFET turn-off, eliminating backfeed leakage <1 μA. |
| Compact Buck Converter Sync Rectifier | Industrial Sensor Signal Conditioning |
|
Use Scenario: Secondary-side synchronous rectification in 3.3 V/1 A isolated DC-DC module for PLC I/O cards. IC Role / Device Role / Timing Role: Q1 replaces Schottky diode; Q2 provides active clamping during light-load discontinuous conduction mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC2038LSD-7 | Same SOT363 package; higher RDS(ON) (0.75 Ω / 1.4 Ω @ 4.5 V); lower Qg (0.65 nC / 0.45 nC). | Better suited for ultra-low-power always-on circuits where gate charge dominates loss. | Select when operating at ≤3.3 V gate drive and average switching frequency <100 kHz. |
| SI6926ADQ-T1-GE3 | SO-8 package; higher current rating (2.5 A / −1.8 A); higher RθJA (110 °C/W). | Requires larger PCB area but supports higher thermal loads in industrial motor drives. | Choose for applications needing >1 A continuous current or extended ambient temperature operation beyond +85 °C. |
Compared with DMC3401LDW-13, DMC2038LSD-7 trades conduction loss for gate drive efficiency at low voltage, while SI6926ADQ-T1-GE3 sacrifices miniaturization for thermal headroom and current capacity-making DMC3401LDW-13 optimal for space-constrained, medium-efficiency 24 V power stages.

FAQ
What is the maximum safe operating junction temperature for DMC3401LDW-13?
The absolute maximum junction temperature is +150 °C, validated across all electrical specifications in the datasheet. Derating begins at +125 °C ambient when mounted on a 1-inch² copper pad (RθJA = 301 °C/W); sustained operation above +135 °C junction requires thermal simulation or derated current limits.
Can DMC3401LDW-13 be used in linear regulator applications?
No-it is not characterized or guaranteed for linear-mode operation. The Safe Operating Area (SOA) curve (Figure 12/24) shows only pulse-limited operation; continuous linear use risks thermal runaway due to positive RDS(ON) temperature coefficient and insufficient thermal mass in SOT363.
Does the DMC3401LDW-13 require external gate resistors for stability?
Yes-external gate resistors (typically 5–22 Ω) are recommended to dampen ringing caused by trace inductance interacting with Ciss (50 pF / 19 pF) and prevent unintended oscillation during fast edge transitions, especially in high-noise industrial environments.
Is the SOT363 package of DMC3401LDW-13 compatible with reflow profiles for lead-free assembly?
Yes-the device is fully RoHS 3 compliant and qualified for standard lead-free reflow (J-STD-020, peak 260 °C, 60 sec max). Its moisture sensitivity level 1 allows unlimited floor life before baking, and matte tin annealed terminations ensure reliable wetting with SAC305 solder paste.
