Product details
Overview
DMN61D9UWQ-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET rated for 60V VDSS, with RDS(ON) = 1.6Ω @ VGS = 5.0V and 2.5Ω @ VGS = 2.5V, delivering 340mA continuous drain current at +25°C. It serves as a low-voltage, low-power switching device in space-constrained automotive and portable power management circuits.
For engineers reviewing the DMN61D9UWQ-7 datasheet, DMN61D9UWQ-7 pinout, DMN61D9UWQ-7 application, or DMN61D9UWQ-7 equivalent, key selection criteria include its AEC-Q101 qualification, SOT323 package footprint, 2kV ESD protection, and gate threshold voltage range of 0.5–1.0V - all critical for robust low-side switching in motor control and backlighting.
Technical Context
This MOSFET employs planar silicon process technology optimized for low RDS(ON) while maintaining fast switching (tD(ON) = 2.1ns, tF = 8.4ns) and low input capacitance (Ciss = 28.5pF). Its gate threshold voltage (0.5–1.0V) enables direct drive from 1.8V/2.5V logic without level shifting.
The integrated body diode supports bidirectional current flow in H-bridge configurations, and thermal resistance RθJA = 289°C/W (t<5s, high-copper PCB) ensures stable operation under pulsed loads up to 1.2A. The device is fully qualified per AEC-Q101 and manufactured in IATF 16949 facilities.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60V - Withstands up to 60V drain-source blocking voltage, suitable for 24V automotive and 3.3V/5V logic-level systems with margin. |
| RDS(ON) | 1.6Ω @ VGS = 5V - Enables <100mW conduction loss at 340mA, critical for thermally constrained SOT323 layouts. |
| ID (continuous) | 340mA @ TA = +25°C - Supports low-power load switching in battery-powered sensors and LED drivers. |
| Qg | 0.4nC - Low gate charge minimizes driver power and enables efficient PWM operation above 1MHz. |
| Ciss | 28.5pF - Reduces Miller effect and improves noise immunity in high-frequency switching nodes. |
| VGS(TH) | 0.5–1.0V - Ensures reliable turn-on with 1.8V microcontroller GPIO, eliminating need for external gate drivers. |
| ESD Rating | 2kV HBM - Integrated protection reduces external TVS requirements in compact consumer and automotive modules. |
Pinout & Package
Package: SOT323 - ultra-small surface-mount plastic package (2.15 × 2.10 × 0.95 mm), lead-free, halogen-free, moisture sensitivity level 1 (J-STD-020).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Current return path for channel conduction | Connected to ground or low-side reference; ties directly to PCB ground plane for thermal and EMI control. |
| 2 (Gate) | Control electrode for channel formation | High-impedance input requiring minimal drive current; sensitive to ESD but protected to 2kV HBM. |
| 3 (Drain) | Current output terminal of the MOSFET channel | Connects to load or higher potential node; exposed pad not present - thermal path relies on trace copper area. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at 2.5V drive | 2.5Ω enables use with 2.5V logic without gate boosting, reducing BOM count in portable designs. |
| Fast switching speed | tF = 8.4ns and tD(OFF) = 14.4ns support >500kHz PWM in backlight dimming and motor commutation. |
| AEC-Q101 qualification | Validated for automotive temperature range (−55°C to +150°C) and reliability stress tests including HTGB and TC. |
| Integrated ESD protection | 2kV HBM rating eliminates need for discrete ESD diodes in cost-sensitive infotainment and body control modules. |
| Green packaging | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) meets automotive OEM environmental mandates. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel low-voltage MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN61D8UWQ-7 | RDS(ON) = 1.2Ω @ 5V (lower), but VGS(TH) = 0.6–1.2V (wider spread); same SOT323 package and AEC-Q101 rating. | Better conduction efficiency at 5V drive, but less predictable turn-on with 1.8V logic due to higher VGS(TH) ceiling. | Select when driving from 3.3V/5V sources and thermal margin is critical; avoid for 1.8V-only systems. |
| NX7002AKW,115 | RDS(ON) = 3.5Ω @ 5V (higher), no AEC-Q101 qualification, lower ESD rating (1.5kV), same SOT323 footprint. | Cost-optimized for industrial/commercial use only; unsuitable for automotive PPAP or extended temperature operation. | Acceptable for non-automotive prototypes or cost-sensitive consumer products where qualification is not required. |
Compared with DMN61D9UWQ-7, DMN61D8UWQ-7 offers lower on-resistance for improved efficiency at 5V drive but sacrifices 1.8V compatibility, while NX7002AKW,115 provides footprint compatibility at lower cost but lacks automotive qualification and thermal robustness.

FAQ
Is DMN61D9UWQ-7 suitable for 1.8V logic-level drive?
Yes. Its gate threshold voltage is specified from 0.5V to 1.0V, ensuring full enhancement with 1.8V gate drive. At VGS = 1.8V and ID = 50mA, RDS(ON) is typically 3.5Ω - sufficient for low-duty-cycle or low-current switching in portable devices.
What is the maximum pulsed drain current rating?
The pulsed drain current (IDM) is rated at 1.2A for 10µs pulses with 1% duty cycle. This rating assumes proper PCB layout (1"×1" 2oz copper) and accounts for thermal limitations during short transients in motor startup or LED surge conditions.
Does DMN61D9UWQ-7 have a built-in body diode?
Yes. It features an integrated parasitic body diode with forward voltage VSD = 0.75V (typical) at IS = 115mA. This diode supports freewheeling current in inductive loads and enables half-bridge operation when paired with a complementary high-side switch.
How does the SOT323 package affect thermal performance?
In the SOT323 package, thermal resistance RθJA is 289°C/W (t<5s, high-copper PCB). This requires careful attention to copper pour area under the drain pad and adjacent traces. Derating is necessary above +70°C ambient to maintain TJ ≤ +150°C.
