Product details
Overview
DMN24H11DSQ-13 from Diodes Incorporated is an AEC-Q101-qualified N-channel enhancement-mode MOSFET in SOT23 package, rated for 240V VDSS, 11Ω RDS(ON) @ VGS = 10V, and 0.27A continuous drain current at +25°C. It serves as a low-power switching device in automotive DC-DC converters, solid-state relays, and battery-management load switches.
For engineers reviewing the DMN24H11DSQ-13 datasheet, DMN24H11DSQ-13 pinout, DMN24H11DSQ-13 application, or DMN24H11DSQ-13 equivalent, key selection criteria include its 1.0–3.0V gate threshold voltage, 76.8pF input capacitance, 3.7nC total gate charge, and suitability for PPAP-capable automotive subsystems operating up to +150°C junction temperature.
Technical Context
This MOSFET employs planar silicon technology optimized for high-voltage, low-current switching with fast turn-on (4.8ns delay) and controlled dv/dt (6.0V/ns). Its low gate threshold enables direct drive from 3.3V/5V microcontrollers without level-shifting.
The device integrates a body diode with 0.7–1.2V forward voltage and 45.6ns reverse recovery time, supporting synchronous rectification and inductive load driving in compact automotive modules where thermal resistance (RθJA = 166°C/W on FR-4) must be managed via PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 240V - Supports 24V/48V automotive bus systems with 2× safety margin against transients. |
| RDS(ON) | 11Ω @ VGS = 10V - Limits conduction loss to ≤0.3W at 0.27A, enabling thermally constrained SOT23 layouts. |
| VGS(TH) | 1.0–3.0V - Ensures reliable turn-on with standard logic-level GPIOs, reducing external driver complexity. |

| Qg | 3.7nC - Allows full switching in <100ns using ≤10mA peak gate current, compatible with MCU GPIOs. |
| TJ Range | −55°C to +150°C - Meets under-hood automotive ambient requirements per AEC-Q101 stress testing. |
| PD | 0.75W (FR-4, min pad) - Defines maximum continuous power dissipation in standard PCB mounting. |

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 |
|---|---|---|---|
| DMN24H11DQ-7 | Same die, identical electrical specs, but packaged in 3,000-piece tape-and-reel (vs. 10,000 for -13). | No functional difference; only packaging quantity and reel size differ. | Select -7 for prototyping or low-volume builds; -13 for production runs requiring higher reel efficiency. |
| DMN2041UFA-7 | Lower VDSS (200V), lower RDS(ON) (4.5Ω @ 4.5V), SOT-23-3L package, AEC-Q101 qualified. | Better suited for 12V systems needing lower on-resistance; not rated for 240V transient margins. | Choose when system max voltage ≤200V and lower conduction loss is prioritized over voltage headroom. |
Compared with DMN24H11DQ-7, the -13 offers identical performance with higher reel quantity; versus DMN2041UFA-7, it trades lower RDS(ON) for higher voltage tolerance-critical for 24V+ automotive bus protection.

FAQ
What is the maximum continuous drain current for DMN24H11DSQ-13 at +70°C ambient?
The maximum continuous drain current is 0.22A at TA = +70°C, derated from 0.27A at +25°C per the datasheet's thermal characteristics table. This reflects junction-to-ambient thermal resistance (166°C/W) and power dissipation limit (0.75W) on standard FR-4 PCB with minimum pad layout.
Is DMN24H11DSQ-13 suitable for driving inductive loads like solenoids?
Yes-it supports pulsed drain current up to 0.8A with 10μs pulse width and ≤1% duty cycle, and its body diode has 45.6ns reverse recovery time and 0.7–1.2V forward voltage, making it appropriate for flyback energy handling in solenoid drivers without external diodes in many cases.
Does DMN24H11DSQ-13 require a gate resistor for MCU GPIO drive?
A small gate resistor (10–100Ω) is recommended to damp ringing and limit peak current, especially given its 3.7nC total gate charge and 17Ω internal gate resistance. While direct GPIO connection is possible, a series resistor improves EMI and prevents overshoot in noisy automotive environments.
How does the SOT23 package affect thermal performance in sustained operation?
On standard FR-4 with minimum pad layout, RθJA is 166°C/W, limiting continuous power to 0.75W. With 2oz copper and 1-inch² pad, RθJA improves to 104°C/W, raising allowable power to ~1.2W-so thermal design must match expected ambient and duty cycle to avoid exceeding +150°C junction temperature.
