Product details
Overview
DMN2310UW-13 from Diodes Incorporated is a 20V N-channel enhancement-mode MOSFET in SOT323 package, optimized for low RDS(ON) (200 mΩ @ VGS = 4.5V) and fast switching in space-constrained power management circuits. It delivers 1.3A continuous drain current at +25°C and supports DC-DC converters, analog switches, and general-purpose interfacing where low gate charge (0.7 nC) and low input capacitance (38 pF) reduce drive losses.
For engineers reviewing the DMN2310UW-13 datasheet, DMN2310UW-13 pinout, DMN2310UW-13 application, or DMN2310UW-13 equivalent, key selection criteria include its 200 mΩ on-resistance at 4.5V gate drive, 0.7 nC total gate charge, SOT323 thermal resistance of 226 °C/W (with thermal pad), 1.3A ID rating, and AEC-Q101 readiness for automotive-grade designs.
Technical Context
This MOSFET operates as a low-voltage, logic-level switch with gate threshold voltage between 0.45 V and 0.95 V, enabling direct drive from 1.8V/2.5V/3.3V microcontrollers. Its RDS(ON) remains stable across −55°C to +150°C junction temperature, varying only 1.6× over full range at VGS = 4.5V.
Designed for high-efficiency operation, it features low output capacitance (Coss = 10 pF) and reverse transfer capacitance (Crss = 6 pF), minimizing Miller effect and improving switching speed. Turn-off delay (181 ns) dominates total switching time, making it suitable for moderate-frequency (<1 MHz) synchronous buck stages and load-switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20 V - Maximum blocking voltage for 3.3V/5V rail switching without derating |
| RDS(ON) | 200 mΩ @ VGS = 4.5V - Enables <130 mW conduction loss at 1.3A, critical for thermally limited SOT323 layouts |
| ID (max) | 1.3 A @ TA = +25°C - Continuous current capability under standard FR-4 PCB conditions with 2 oz copper |
| Qg | 0.7 nC - Low gate drive energy reduces MCU GPIO stress and enables efficient 1–2 MHz PWM control |

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 |
|---|---|---|---|
| DMN2016LSD-13 | Lower RDS(ON) (160 mΩ @ 4.5V), higher ID (2.0A), but larger SOT523 package (2.1 × 1.25 × 0.95 mm) | Requires more PCB area; better suited for higher-current loads where thermal headroom exists | Select when >1.3A continuous current or lower conduction loss is required and board space permits SOT523 |
| AO3414 | Higher RDS(ON) (210 mΩ @ 4.5V), same SOT23-3 footprint, but not AEC-Q101 qualified | Lacks automotive qualification and tighter VGS(TH) distribution; lower gate charge (0.55 nC) | Prefer for cost-sensitive consumer applications where AEC-Q101 compliance is unnecessary and gate drive is extremely light |
Compared with DMN2310UW-13, DMN2016LSD-13 offers higher current capacity at the expense of footprint size, while AO3414 trades automotive qualification and tighter threshold control for slightly lower gate charge-making DMN2310UW-13 the optimal balance of miniaturization, thermal performance, and automotive-readiness in SOT323.

FAQ
What is the maximum continuous drain current for DMN2310UW-13 at +70°C ambient?
The DMN2310UW-13 supports 1.1 A continuous drain current at TA = +70°C under standard FR-4 PCB conditions with 2 oz copper and thermal bias to a 1-inch² copper plate. This reflects thermal derating from 1.3 A at +25°C due to reduced heat dissipation capability at elevated ambient temperatures.
Is DMN2310UW-13 qualified for automotive applications?
Yes-DMN2310UW-13 is AEC-Q101 qualified and manufactured in IATF 16949 certified facilities. It meets PPAP requirements and supports automotive change control protocols, making it suitable for body electronics, infotainment power rails, and ADAS subsystems where reliability and process traceability are mandated.
Can DMN2310UW-13 be used as a high-side switch with 3.3V gate drive?
Yes-its gate threshold voltage (0.45–0.95 V) and guaranteed RDS(ON) of 200 mΩ at VGS = 4.5V and 280 mΩ at VGS = 2.5V confirm reliable enhancement-mode operation with 3.3V logic. For high-side configuration, ensure gate drive referenced to source (e.g., using charge pump or level shifter) to maintain VGS ≥ 2.5V under load.
What is the safe operating area (SOA) limitation at DC for DMN2310UW-13?
At DC, the SOA is limited by RDS(ON) conduction and thermal resistance. With RDS(ON) = 200 mΩ and RθJA = 226 °C/W, maximum DC power dissipation is 0.55 W, corresponding to ~1.65 A at 20V VDS-but practical DC current is capped at 1.3 A by package and bondwire limits per datasheet absolute maximum ratings.
