Product details
Overview
DMN3110SQ-7 from Diodes Incorporated is an AEC-Q101-qualified N-channel enhancement-mode MOSFET in SOT23 package, rated for 30V VDSS, 73mΩ RDS(ON) @ 10VGS, and 3.3A ID @ 4.5VGS. It serves as a high-reliability power switch in automotive power management, boost converters, and analog switching circuits.
For engineers reviewing the DMN3110SQ-7 datasheet, DMN3110SQ-7 pinout, DMN3110SQ-7 application, or DMN3110SQ-7 equivalent, key selection criteria include its low 110mΩ RDS(ON) at 4.5VGS, 305.8pF Ciss, AEC-Q101 qualification, SOT23 thermal performance (RθJA = 173.4°C/W), and PPAP-capable automotive supply chain support.
Technical Context
This MOSFET employs planar silicon process technology optimized for low gate charge (Qg = 8.6nC @ 10VGS) and fast switching (tr = 4.6ns, tf = 2.5ns), enabling efficient operation in DC-DC boost stages and load-switching applications up to 30V. Its 1.0–3.0V VGS(TH) range ensures robust turn-on with standard logic-level drivers.
Thermal design is constrained by its SOT23 package: maximum steady-state power dissipation is 0.74W on FR-4 PCB (RθJA = 173.4°C/W), rising to 1.8W under 10-second pulsed conditions. The integrated body diode exhibits VSD = 0.75V @ 1A, supporting synchronous rectification and reverse-current blocking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Maximum drain-source blocking voltage; supports 24V automotive rail and 12V boost outputs. |
| RDS(ON) | 73mΩ @ 10VGS, 110mΩ @ 4.5VGS - Enables <100mW conduction loss at 2.7A in 4.5V logic-driven loads. |
| ID (max) | 3.3A @ 4.5VGS, 25A pulsed - Sustains continuous current for small-signal power switches and transient peak loads. |
| Ciss | 305.8pF @ 15VDS - Low input capacitance reduces gate drive power and improves switching efficiency above 1MHz. |
| Qg | 8.6nC @ 10VGS - Minimizes gate driver current demand and enables fast turn-on with low-RG drivers. |
| TJ Range | −55°C to +150°C - Rated for under-hood automotive environments and industrial temperature cycling. |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with matte tin annealed terminals, UL 94V-0 rating, moisture sensitivity level 1, and 0.027g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Source terminal | Reference node for gate control; connects to ground or low-side return path in switching topologies. |
| 2 (Gate) | Control input | Receives logic-level voltage (≥4.5V) to fully enhance channel; requires <8.6nC charge for full turn-on. |
| 3 (Drain) | Power output | Carries switched load current; must be routed with adequate copper area to manage 0.74W steady-state dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use with PPAP documentation support and failure rate <10 FIT over 15-year lifetime. |

Applications
| Automotive Body Control Module | USB-C Power Delivery Switch |
|---|---|
Use Scenario: Controlling 12V accessory loads (e.g., LED lighting, solenoids) in vehicle door modules and seat controls. IC Role / Device Role / Timing Role: Low-side power switch managing ON/OFF state of resistive and inductive loads. Use Value: AEC-Q101 qualification ensures reliability across −40°C to +125°C ambient; 110mΩ RDS(ON) limits self-heating during sustained 2.7A operation. |
Use Scenario: Enabling/disabling VBUS path in USB-C receptacles with 5–20V input range and 3A max current. IC Role / Device Role / Timing Role: Bidirectional load switch with integrated body diode for reverse-current blocking. Use Value: 30V VDSS headroom accommodates 20V PD3.0 transients; 0.75V VSD minimizes forward drop during source-sinking mode. |
| Industrial Sensor Interface | Portable Medical Device Power Sequencing |
Use Scenario: Isolating analog sensor supplies (e.g., pressure, temperature) from shared MCU rails to reduce noise coupling. IC Role / Device Role / Timing Role: Precision analog switch with low leakage (IDSS ≤ 1μA) and minimal on-resistance variation. Use Value: 1.0–3.0V VGS(TH) window ensures clean turn-on at 3.3V logic; 39.5pF Crss suppresses Miller-induced shoot-through. |
Use Scenario: Sequencing power to RF transceivers and ADCs in handheld diagnostic tools requiring strict startup timing. IC Role / Device Role / Timing Role: Controlled enable switch with fast tON = 2.6ns delay and sub-10ns rise time. Use Value: Low Qg (4.1nC @ 4.5VGS) allows precise timing control using standard GPIO; SOT23 footprint saves board space in compact enclosures. |
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 |
|---|---|---|---|
| DMN3025LSD-13 | Lower RDS(ON) (25mΩ @ 4.5VGS), but larger TSOP-6 package and higher Ciss (620pF). | Preferred for higher-current (>4A) or lower-loss requirements where board space permits larger footprint. | Select when thermal budget allows higher ID and lower conduction loss outweighs SOT23 size advantage. |
| AO3400 | Similar RDS(ON) (45mΩ @ 10VGS, 65mΩ @ 4.5VGS), but not AEC-Q101 qualified and lacks PPAP support. | Suitable for commercial-grade consumer electronics, not automotive or safety-critical systems. | Choose only for cost-sensitive non-automotive designs where qualification and traceability are not required. |
Compared with DMN3110SQ-7, DMN3025LSD-13 delivers superior conduction efficiency in larger packages, while AO3400 offers lower cost at the expense of automotive compliance and guaranteed reliability data - making DMN3110SQ-7 the optimal choice for space-constrained, AEC-Q101-mandated applications.

FAQ
Is DMN3110SQ-7 suitable for 3.3V GPIO direct drive?
Yes. With a gate threshold voltage range of 1.0–3.0V and RDS(ON) = 110mΩ at VGS = 4.5V, the device achieves full enhancement using standard 3.3V microcontroller outputs. At 3.3VGS, RDS(ON) rises to ~140mΩ (per Fig. 4), still supporting ≤2A loads with acceptable conduction loss.
What is the maximum continuous power dissipation on a standard FR-4 PCB?
When mounted on FR-4 with minimum recommended pad layout, DMN3110SQ-7 has a steady-state power dissipation limit of 0.74W (RθJA = 173.4°C/W). This corresponds to ~2.7A at 110mΩ RDS(ON) at +25°C ambient, derating linearly above 25°C per the thermal resistance curve in Fig. 12.
Does DMN3110SQ-7 include an integrated ESD protection diode?
No. The device does not integrate dedicated ESD protection structures. Its gate oxide is rated for ±20V VGSS, and system-level ESD protection (e.g., TVS diodes on gate/drain lines) is required per IEC 61000-4-2 Level 4 when used in exposed interfaces such as USB-C or automotive harness connections.
Can DMN3110SQ-7 replace Si2300DS in existing designs?
Functionally yes, but with critical differences: DMN3110SQ-7 has higher RDS(ON) (110mΩ vs. 60mΩ @ 4.5VGS) and lower ID rating (2.7A vs. 3.0A), yet adds AEC-Q101 qualification and PPAP support. Thermal validation is required if replacing in thermally constrained layouts.
