Product details
Overview
DMN2310UTQ-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in SOT523 package, rated for 20V VDSS, 240mΩ RDS(on) at VGS = 4.5V and 1.2A continuous drain current at TA = +25°C. It serves as a low-voltage load switch or synchronous rectifier in space-constrained DC-DC converters.
For engineers reviewing the DMN2310UTQ-7 datasheet, DMN2310UTQ-7 pinout, DMN2310UTQ-7 application, or DMN2310UTQ-7 equivalent, key selection criteria include its ultra-small SOT523 footprint, 174mΩ typical RDS(on) at 4.5V, 38pF Ciss, ESD-protected gate, and AEC-Q101 qualification for automotive power management.
Technical Context
This MOSFET employs planar trench-gate technology to achieve low on-resistance while maintaining fast switching (tR = 138ns, tF = 180ns) and low gate charge (Qg = 0.7nC). Its 0.002g mass and 1.6mm × 1.6mm SOT523 outline support high-density PCB layouts.
Designed for 1.8V–4.5V logic-level drive, it delivers 211mΩ RDS(on) at VGS = 2.5V and 263mΩ at VGS = 1.8V, enabling direct interface with low-voltage microcontrollers and PMICs without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20V - supports input rails up to 18V in USB PD, battery-powered, and automotive accessory circuits |
| RDS(on) @ VGS = 4.5V | 240mΩ max - limits conduction loss to ≤0.35W at 1.2A, critical for thermally constrained SOT523 layout |
| Qg | 0.7nC - enables efficient 1MHz+ switching in buck converters with minimal gate-drive power |
| Ciss | 38pF - reduces Miller effect and improves noise immunity in high-dv/dt environments |
| TJ Range | −55°C to +150°C - qualified per AEC-Q101 for under-hood automotive modules and industrial controllers |
| PD (FR-4, 2oz Cu) | 0.49W - defines maximum steady-state power handling with thermal pad bias to inner copper layer |
Pinout & Package
SOT523 is a 3-pin ultra-small surface-mount package (1.60mm × 1.60mm × 0.90mm), optimized for high-volume automated assembly and minimal board area consumption in portable electronics.

| Source (S) | Reference node for gate drive and current return path | Internally connected to die substrate; requires low-impedance PCB ground plane for thermal and switching stability |
| Drain (D) | Power output terminal | Carries switched load current; connects to output rail in high-side or low-side configurations |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) at 2.5V drive | 300mΩ max - enables use with 2.5V I/O domains in modern SoCs and MCUs without gate drivers |
| Low input capacitance | Ciss = 38pF - minimizes gate-drive energy and improves switching efficiency in high-frequency DC-DC stages |
| Fast turn-off capability | tD(off) = 154ns, tF = 180ns - reduces dead-time losses and supports synchronous rectification in buck converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2016LFG-7 | Lower RDS(on) (160mΩ @ 4.5V), same SOT523 package, but higher Qg (1.1nC) | Better conduction loss, but slower switching and higher gate-drive demand | Prefer when thermal budget dominates over switching frequency (e.g., <500kHz DC-DC) |
| AO3414 | Higher RDS(on) (45mΩ @ 4.5V), larger SOT23 package, AEC-Q101 not claimed | Higher current rating (4.2A), but unsuitable for space-constrained automotive designs | Select only if board area allows SOT23 and AEC-Q101 compliance is not required |
Compared with DMN2310UTQ-7, DMN2016LFG-7 trades faster switching for lower conduction loss, while AO3414 sacrifices miniaturization and automotive qualification for higher current capacity-making DMN2310UTQ-7 optimal for ultra-compact, AEC-Q101-compliant 1–1.2A load switching.

FAQ
What is the maximum continuous drain current for DMN2310UTQ-7 at +75°C ambient?
At TA = +75°C, the maximum continuous drain current is 1.0A with VGS = 4.5V, based on thermal derating from the 0.49W power dissipation limit on a 2oz FR-4 board with thermal bias. This reflects a 17% reduction from the +25°C rating of 1.2A due to junction-to-ambient thermal resistance (RθJA = 253°C/W).
Is DMN2310UTQ-7 suitable for reverse-polarity protection?
Yes-its body diode forward voltage is 0.8–1.2V at 1A, and its 20V VDSS rating supports standard 12V automotive and 5V USB systems. When used in high-side configuration with gate driven above source, it blocks reverse current while maintaining low forward drop, provided external gate control ensures proper turn-on timing.
Does DMN2310UTQ-7 require a gate resistor for ESD protection?
No-its gate is internally ESD-protected to ±2kV HBM per JESD22-A114, eliminating need for external series resistors in most applications. However, a 10Ω gate resistor is recommended in high-noise environments (e.g., motor drives) to dampen ringing and reduce dv/dt-induced false turn-on.
Can DMN2310UTQ-7 be used in parallel with identical units for higher current handling?
Not recommended-its positive temperature coefficient of RDS(on) (normalized to 1.4× at 150°C) provides limited inherent current sharing. Without matched gate drive and symmetrical PCB layout, imbalance exceeding 30% can occur. For >1.2A loads, select a single higher-rated device such as DMN2016LFG-7 instead.
