Product details
Overview
DMN2310UTQ-13 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 delivers low gate charge (0.7nC), fast switching (tR = 138ns), and ESD-protected gate for robust load-switching in space-constrained power rails.
For engineers reviewing the DMN2310UTQ-13 datasheet, DMN2310UTQ-13 pinout, DMN2310UTQ-13 application, or DMN2310UTQ-13 equivalent, this page provides verified electrical parameters, thermal behavior under pulsed and steady-state conditions, SOT523 terminal mapping, and validated automotive-grade alternatives for DC-DC converter and battery protection designs.
Technical Context
This MOSFET operates as a low-voltage, logic-level power switch with gate threshold voltage (VGS(th)) ranging from 0.45V to 0.95V, enabling direct drive from 1.8V/2.5V/3.3V microcontrollers. Its ultra-low input capacitance (Ciss = 38pF) and reverse transfer capacitance (Crss = 6pF) minimize Miller effect and support high-frequency switching up to several MHz.
The device features integrated body diode with VSD = 0.8–1.2V at IS = 1A and exhibits normalized RDS(on) variation of ≤1.4× across −55°C to +150°C junction temperature, ensuring stable conduction in thermally demanding environments such as automotive cabin modules and portable battery management systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20V - supports 12V rail switching and USB PD auxiliary power paths without derating |
| RDS(on) | 240mΩ @ VGS = 4.5V - enables <150mW conduction loss at 1.2A, critical for thermally isolated PCBs |
| ID (continuous) | 1.2A @ TA = +25°C - sufficient for single-cell Li-ion load switching and PMIC enable control |
| Qg | 0.7nC - reduces gate driver power demand and enables efficient operation with low-current GPIOs |
| tR/tF | 138ns / 180ns - supports >1MHz PWM in buck converters while limiting switching losses |
| RθJA | 253°C/W (2oz copper pad) - defines thermal rise of ~64°C at 0.25W dissipation, guiding heatsinking decisions |
| Ciss/Coss | 38pF / 10pF - ensures minimal capacitive loading on driving ICs and stable loop response in feedback-controlled regulators |
Pinout & Package
SOT523 is a 3-pin ultra-small surface-mount package (1.60 × 1.60 × 0.75 mm) with gull-wing leads, optimized for high-density layouts in wearables, hearing aids, and compact IoT sensors. Its matte tin–annealed terminals meet MIL-STD-202 solderability requirements and J-STD-020 Level 1 moisture sensitivity classification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Current return path for channel conduction | Connected to ground or low-side reference; forms common node with body diode cathode |
| 2 (Gate) | Control electrode for channel formation | ESD-protected input requiring <10μA leakage; driven directly by 1.8V–4.5V logic |
| 3 (Drain) | Power output terminal | Carries switched load current; electrically isolated from package tab (no thermal pad) |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) at 2.5V drive | 300mΩ - enables reliable turn-on from legacy 2.5V supply rails without level-shifting |
| Ultra-low Ciss | 38pF - minimizes gate drive energy and improves EMI performance in high-frequency SMPS |
| Fast tD(on)/tD(off) | 8ns / 154ns - reduces dead-time losses in synchronous rectification and half-bridge topologies |
| ESD-protected gate | HBM >2kV - eliminates need for external gate protection in handheld and automotive infotainment modules |
| Green, halogen-free construction | <900ppm Br+Cl, <1000ppm Sb - meets automotive OEM material compliance requirements (e.g., GMW3172, Ford WSS-M99P9999-A1) |

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, higher Qg (1.1nC) | Better conduction loss but slower switching; less suitable for >1MHz DC-DC | Select when thermal margin is constrained and switching frequency ≤500kHz |
| AO3414 | Higher RDS(on) (440mΩ @ 4.5V), SOT23 package, lower cost | Larger footprint, higher conduction loss, not AEC-Q101 qualified | Select for non-automotive consumer applications where board area and qualification are secondary |
Compared with DMN2310UTQ-13, DMN2016LFG-7 trades gate charge for lower on-resistance-ideal for thermally limited 12V-to-3.3V conversion-while AO3414 offers cost savings in non-automotive spaces where SOT23 fit and AEC-Q101 compliance are unnecessary.

FAQ
Is DMN2310UTQ-13 AEC-Q101 qualified?
Yes. DMN2310UTQ-13 is AEC-Q101 qualified and manufactured in IATF 16949 certified facilities. It meets stress test requirements including HTGB, HTRB, and TC1000, with full PPAP documentation available upon request for automotive customers.
What is the maximum safe operating temperature for DMN2310UTQ-13?
The absolute maximum junction temperature is +150°C. Under continuous 1.2A operation at TA = +25°C with 2oz copper thermal pad, junction temperature reaches ~89°C. Derating is required above +75°C ambient to maintain reliability per Figure 5 and Figure 7 in DS42755 Rev. 3-2.
Can DMN2310UTQ-13 be used in reverse conduction mode?
No. While it contains an intrinsic body diode (anode at source, cathode at drain), the device is designed for unidirectional drain-to-source conduction. Reverse current flow (source-to-drain) exceeds safe SOA limits beyond 0.6A and is not characterized for sustained operation.
Does DMN2310UTQ-13 require a gate resistor in typical load-switch applications?
A gate resistor is recommended for EMI control and ringing suppression. For 1.2A switching at ≤1MHz, a 10Ω–47Ω series resistor limits dV/dt and prevents oscillation, especially when driving from high-impedance GPIOs. No resistor is needed for static on/off control with low-capacitance drivers.
