Product details
Overview
DMN3061SWQ-7 from Diodes Incorporated is an AEC-Q101 qualified N-channel enhancement-mode MOSFET in SOT323 package, rated for 30V VDSS, 60mΩ RDS(ON) @ 10V VGS, and 2.7A continuous drain current at +25°C. It delivers low on-resistance with fast switching (tR = 97ns, Qg = 3.5nC) and is optimized for automotive-grade power management in space-constrained DC-DC converters and load switches.
For engineers reviewing the DMN3061SWQ-7 datasheet, DMN3061SWQ-7 pinout, DMN3061SWQ-7 application, or DMN3061SWQ-7 equivalent, key selection criteria include its AEC-Q101 qualification, 100mΩ RDS(ON) @ 4.5V VGS, thermal resistance of 254°C/W (RθJA), SOT323 footprint compatibility, and body diode forward voltage of 0.7V @ 1A.
Technical Context
This MOSFET employs planar silicon technology with a fully isolated gate structure to achieve stable threshold voltage (VGS(TH) = 0.5–1.8V) and low input capacitance (Ciss = 278pF). Its design targets high-efficiency, low-voltage switching where gate drive capability is limited to 3.3V or 4.5V logic levels.
The device integrates a monolithic body diode with VSD = 0.7V @ 1A and supports pulsed drain currents up to 22A (10µs, 1% duty). Thermal performance is specified for FR-4 PCB mounting with minimum pad layout (RθJA = 254°C/W) and enhanced layout (RθJA = 191°C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Maximum blocking voltage before avalanche conduction; suitable for 24V automotive rail and 12V industrial systems. |
| RDS(ON) | 60mΩ @ 10V VGS - Enables <170mW conduction loss at 2.7A; critical for thermally constrained SOT323 layouts. |
| ID (continuous) | 2.7A @ +25°C - Rated current under standard JEDEC test conditions; derates to 2.2A at +70°C ambient. |
| Qg | 3.5nC - Low total gate charge reduces driver power demand and enables efficient 1MHz+ switching in buck regulators. |
| tR/tF | 97ns/51ns - Fast edge rates minimize switching losses in high-frequency DC-DC topologies with tight layout constraints. |
| TJ range | −55°C to +150°C - Full automotive temperature range support confirmed by AEC-Q101 stress testing. |
Pinout & Package
SOT323 surface-mount package: 3-pin, single-ended leadframe, matte tin-plated copper terminals, UL 94V-0 molded plastic body, 0.027g weight, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G | Gate | Control terminal requiring ≥0.5V VGS(TH) to initiate conduction; driven by 3.3V/4.5V/10V logic sources. |
| S | Source | Reference node for gate drive and current return path; connects to ground or low-side common in switch configurations. |
| D | Drain | High-side current output terminal; handles bidirectional current flow including body diode conduction (S→D). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control modules and ADAS power stages per IATF 16949 manufacturing. |
| Low RDS(ON) @ 4.5V | 100mΩ ensures <210mW conduction loss at 2.1A - enables direct interface with 4.5V microcontroller GPIO without level-shifting. |
| Low Ciss & Crss | 278pF input capacitance and 29pF reverse transfer capacitance reduce Miller effect and improve gate drive efficiency. |
| Green compound | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) meets automotive environmental compliance requirements. |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Load Switch |
|---|---|
Use Scenario: Low-side switching of 12V lighting loads (LED lamps, interior lights) in vehicle BCMs with strict thermal and space constraints. IC Role / Device Role / Timing Role: N-channel load switch controlling power delivery to distributed lighting circuits; operates in static on/off mode with occasional PWM dimming. Use Value: 60mΩ RDS(ON) limits self-heating to <430mW at 2.7A, enabling reliable operation within SOT323's 0.49W PD limit at +70°C ambient. |
Use Scenario: Input protection and hot-swap control in USB-C PD sink ports requiring 5–20V input tolerance and fast fault response. IC Role / Device Role / Timing Role: Reverse-polarity and overcurrent protected high-side switch; activated only during valid VBUS presence and negotiated voltage. Use Value: 30V VDSS headroom accommodates 20V PD profiles plus transients; 97ns tR enables rapid enable/disable during port negotiation sequences. |
| Industrial Sensor Node Power Gate | Portable Medical Device Battery Switch |
Use Scenario: Power gating of ultra-low-power sensor subsystems (e.g., temperature/humidity sensors) in battery-operated IIoT nodes. IC Role / Device Role / Timing Role: Low-leakage (IDSS ≤ 1µA) enable switch isolating sensor supply rails during deep sleep modes. Use Value: Sub-µA off-state leakage preserves battery life over multi-year deployments; SOT323 footprint minimizes PCB area in compact sensor housings. |
Use Scenario: Isolation of Li-ion battery packs from patient-monitoring circuitry during charging or fault conditions in portable ECG/SpO₂ devices. IC Role / Device Role / Timing Role: Fail-safe battery disconnect switch controlled by safety MCU; must withstand 150°C junction temperature during thermal runaway events. Use Value: +150°C TJ(max) rating and AEC-Q101 qualification ensure robustness under fault conditions; 0.7V body diode VSD prevents backfeed during charger insertion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3025LFG-7 | Lower RDS(ON) (25mΩ @ 10V), higher ID (4.2A), same SOT323 package but larger die; Qg = 5.8nC. | Better for higher-current DC-DC outputs; less suitable for 3.3V-only gate drive due to higher VGS(TH) (1.0–2.5V). | Select when >3A continuous current is required and gate drive supports ≥4.5V; avoid if driving from 3.3V GPIO with marginal margin. |
| AO3400 | Same VDSS (30V), higher RDS(ON) (44mΩ @ 10V), different package (SOT23); not AEC-Q101 qualified. | Cost-optimized for consumer electronics; lacks automotive qualification and traceability documentation. | Acceptable for non-automotive, non-safety-critical applications where AEC-Q101 is not mandated and SOT23 footprint is acceptable. |
Compared with DMN3061SWQ-7, DMN3025LFG-7 offers lower conduction loss at higher currents but requires stronger gate drive, while AO3400 sacrifices automotive reliability and thermal performance for cost-making DMN3061SWQ-7 the optimal balance for space-limited, AEC-Q101–required 2–3A switching.

FAQ
Is DMN3061SWQ-7 pin-compatible with standard SOT323 N-channel MOSFETs?
Yes - DMN3061SWQ-7 uses the industry-standard SOT323 pinout: Pin 1 = Gate, Pin 2 = Source, Pin 3 = Drain (top view, marking side up). This matches JEDEC MO-203AA and is mechanically and electrically compatible with other SOT323-packaged N-channel MOSFETs, though electrical parameters (e.g., RDS(ON), Qg) differ.
What is the maximum allowable PCB copper area for thermal improvement in the DMN3061SWQ-7 layout?
Per the datasheet, thermal performance improves significantly with a 1-inch square copper plate connected to the source pad on the bottom layer (2oz copper). This configuration reduces RθJA from 254°C/W to 191°C/W. No larger area is specified or tested - further expansion yields diminishing returns and may violate spacing rules in dense layouts.
Does DMN3061SWQ-7 support 3.3V logic-level gate drive reliably?
Yes - with VGS(TH) as low as 0.5V and RDS(ON) = 200mΩ @ 3.3V VGS (ID = 1.5A), it achieves functional switching at 3.3V. However, conduction loss increases ~3.3× versus 10V drive; use only where 1.5A max load and thermal margin permit.
How does the body diode performance impact reverse-current protection in load-switch applications?
The integrated body diode has VSD = 0.7V @ 1A and supports bidirectional current flow. In high-side load switches, it conducts reverse current if output voltage exceeds input - so external reverse-blocking diodes or complementary FETs are needed for true bidirectional isolation. It is not rated for sustained reverse conduction beyond IS = 0.67A.
