Product details
Overview
DMN3190LDWQ-7 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SOT363 package, rated for 30V VDSS, 190mΩ RDS(ON) @ 10VGS, and 1A continuous drain current at +25°C. It is AEC-Q101 qualified, PPAP-capable, and designed for automotive motor control, DC-DC converters, and load switching.
For engineers reviewing the DMN3190LDWQ-7 datasheet, DMN3190LDWQ-7 pinout, DMN3190LDWQ-7 application, or DMN3190LDWQ-7 equivalent, key selection criteria include dual-N-channel topology, low RDS(ON) at 4.5VGS (335mΩ), AEC-Q101 qualification, thermal resistance of 320°C/W (steady-state), and SOT363 footprint compatibility with space-constrained automotive PCBs.
Technical Context
This dual MOSFET integrates two independent N-channel devices in a single SOT363 package, each featuring ESD-protected gate structures and optimized for low-voltage logic-level drive (4.5VGS capable). Its 30V breakdown voltage and 1A steady-state current rating support 12V automotive rail switching.
The device exhibits fast switching performance (tD(ON) = 4.5ns, tF = 15.6ns) and low input capacitance (Ciss = 87pF), enabling high-frequency operation in DC-DC converter topologies while maintaining low gate drive power loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - supports 12V automotive systems with margin against transients |
| RDS(ON) @ 10VGS | 190mΩ max - enables <190mW conduction loss at 1A, critical for thermally constrained modules |
| RDS(ON) @ 4.5VGS | 335mΩ max - ensures reliable turn-on with standard 5V microcontroller GPIO |
| ID (continuous, TA=+25°C) | 1A - suitable for low-power motor drivers and auxiliary load switches |
| Ciss | 87pF - reduces gate drive energy and improves switching efficiency in >500kHz converters |
| RθJA (steady-state) | 320°C/W - defines thermal derating on standard FR-4; requires minimal copper area for 0.4W dissipation |
| TJ range | −55°C to +150°C - meets under-hood automotive temperature requirements |
Pinout & Package
Package: SOT363 - 6-pin, surface-mount, dual-source/dual-drain configuration with exposed thermal pad (not electrically connected); dimensions: 2.15mm × 2.10mm × 0.95mm height; moisture sensitivity level 1.

| 2 (D1) | Drain of Q1 | Switched output terminal for Q1; connects to load or inductive flyback path |
| 3 (G1) | Gate of Q1 | Logic-level control input for Q1; includes integrated ESD protection diode to S1 |
| 4 (G2) | Gate of Q2 | Independent logic-level control input for Q2; ESD protected to S2 |
| 5 (D2) | Drain of Q2 | Switched output terminal for Q2; electrically isolated from D1 |
| 6 (S2) | Source of Q2 | Low-side return path for second MOSFET; may be tied to S1 or kept separate |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at 4.5VGS | 335mΩ max - eliminates need for gate boosters in 5V MCU-driven loads |
| ESD-protected gates | ±20V VGSS rating with integrated diodes - prevents latch-up during board handling and system integration |
| AEC-Q101 qualification | Validated for automotive use per stress test conditions - required for Tier-1 supplier BOMs |
| Green, halogen-free construction | <900ppm Br/Cl, <1000ppm Sb - satisfies EU automotive environmental compliance mandates |
| Fast switching speed | tF = 15.6ns - minimizes transition losses in 1–2MHz synchronous buck stages |
Applications

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 | Lower RDS(ON) (25mΩ @ 4.5VGS), higher ID (3.8A), same SOT363 package | Better suited for higher-current motor drives (>1.5A), but requires larger gate drive capability | Select when thermal budget allows higher peak currents and gate drive can support 2.0nC Qg |
| NTJD4152PZ-1 | Higher RDS(ON) (420mΩ @ 4.5VGS), lower VDSS (20V), same footprint | Limited to 5V/3.3V logic systems; not AEC-Q101 qualified | Acceptable for non-automotive consumer applications where cost is prioritized over qualification and performance |
Compared with DMN3190LDWQ-7, DMN3025LFD-7 delivers significantly lower conduction loss but demands more gate charge; NTJD4152PZ-1 offers cost advantage in non-automotive designs but lacks AEC-Q101 validation and thermal robustness for under-hood use.

FAQ
Is DMN3190LDWQ-7 suitable for hot-swap applications?
No - DMN3190LDWQ-7 lacks integrated slew-rate control, current limiting, or fault reporting circuitry required for safe hot-swap insertion. Its gate threshold (1.5–2.8V) and lack of built-in charge pump make it vulnerable to inrush-induced shoot-through. Use dedicated hot-swap controllers like DIODES AP22802W5-7 for such applications.
What is the maximum safe operating frequency for DMN3190LDWQ-7 in a synchronous buck converter?
Based on its 15.6ns fall time and 87pF Ciss, DMN3190LDWQ-7 supports stable operation up to 2MHz with appropriate gate driver strength (≥1A peak) and layout optimization. Above 1.5MHz, gate drive impedance must be ≤5Ω to avoid ringing and ensure clean transitions.
Can both channels be paralleled to increase current capacity?
No - the two N-channel MOSFETs share no internal thermal coupling or matching; paralleling risks current imbalance due to VGS(TH) mismatch (±0.65V) and differing RDS(ON) drift with temperature. For higher current, use a single-channel part like DMN3025LFD-7 instead.
Does DMN3190LDWQ-7 require external gate resistors in automotive applications?
Yes - a 10Ω series gate resistor is recommended per channel to dampen oscillation caused by PCB trace inductance and gate capacitance interaction. This prevents false triggering during ESD events and ensures controlled turn-on in noisy automotive environments per ISO 11452-4.
