Product details
Overview
DMN3066LQ-13 from Diodes Incorporated is an AEC-Q101 qualified N-channel enhancement-mode MOSFET in SOT23 package, rated for 30V VDSS, 67mΩ RDS(ON) @ 4.5V VGS, and 3.6A continuous drain current at +25°C. It serves as a low-voltage load switch in automotive power rails and USB port protection circuits.
For engineers reviewing the DMN3066LQ-13 datasheet, DMN3066LQ-13 pinout, DMN3066LQ-13 application, or DMN3066LQ-13 equivalent, key selection criteria include gate threshold voltage (0.5–1.5V), fast switching performance (tD(ON) = 5.7ns), ESD-protected gate, and IATF 16949 manufacturing compliance.
Technical Context
This MOSFET employs planar trench-gate technology to achieve low RDS(ON) while maintaining robust switching characteristics. Its 0.5–1.5V gate threshold enables direct drive from 1.8V/3.3V logic and supports low-power wake-up functionality in battery-powered systems.
Thermal design is enabled by two distinct RθJA ratings: 154°C/W on minimal FR-4 layout and 94°C/W with 1-inch² copper pad-critical for sustained 2.9A operation at +85°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Supports 24V automotive supply rails with 20% margin against transients. |
| RDS(ON) | 67mΩ @ 4.5V VGS - Limits conduction loss to ≤0.61W at 3.6A, enabling compact thermal design. |
| ID (TA = +25°C) | 3.6A - Sustains full-rated load in ambient-cooled consumer and automotive control modules. |
| VGS(TH) | 0.5–1.5V - Ensures reliable turn-on with 1.8V GPIOs and reduces shoot-through risk in half-bridge configurations. |
| Qg | 4.1nC - Enables efficient 1MHz switching with <1.5W gate driver power at 5V drive. |
| tD(ON)/tF | 5.7ns / 11ns - Minimizes dead-time requirements and improves efficiency in high-frequency DC-DC converters. |
| PD (with pad) | 1.33W - Allows 2.9A continuous current at +85°C ambient when using recommended copper area. |
Pinout & Package
SOT23-3 package: ultra-compact surface-mount outline (2.4mm × 1.3mm × 0.9mm), RoHS-compliant matte tin finish, moisture sensitivity level 1, weight 0.008g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Power return path | Connected to system ground or low-side reference; carries full load current with minimal IR drop. |
| 2 (Gate) | Control input | ESD-protected node accepting 0–4.5V logic; requires <4.1nC charge for full enhancement. |
| 3 (Drain) | Power output | Switches 30V loads; internal body diode provides reverse-current blocking in load-switch applications. |
Key Features
| Feature | Design Value |
|---|---|
| Low gate threshold voltage | 0.5–1.5V range ensures compatibility with 1.8V microcontrollers and reduces false turn-on during brown-out conditions. |
| Fast switching speed | 5.7ns turn-on delay + 11ns fall time minimizes transition losses in 500kHz–1MHz power management ICs. |
| ESD-protected gate | HBM rating ≥2kV per JESD22-A114 - eliminates need for external gate protection in board-level ESD environments. |
| AEC-Q101 qualification | Validated for automotive temperature range (−55°C to +150°C) and PPAP-capable production in IATF 16949 facilities. |
| Green packaging | Halogen- and antimony-free molding compound (<900ppm Br+Cl, <1000ppm Sb) meets automotive OEM environmental mandates. |
Applications
| Automotive Body Control Module | USB Type-C Port Power Switch |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3025LQ-7 | Lower RDS(ON) (25mΩ @ 4.5V), higher Qg (6.8nC), same SOT23 package | Better conduction loss but slower switching; suited for <500kHz applications where efficiency > speed | Select when thermal budget is tighter than timing budget, e.g., always-on industrial sensors |
| AO3400 | Higher RDS(ON) (42mΩ @ 4.5V), no AEC-Q101 qualification, non-automotive grade | Lacks PPAP support and extended temperature validation; limited to commercial-grade consumer products | Choose only for cost-sensitive non-automotive designs where qualification documentation is not required |
Compared with DMN3066LQ-13, DMN3025LQ-7 trades faster switching for lower conduction loss, while AO3400 sacrifices automotive qualification and thermal robustness for lower unit cost-making DMN3066LQ-13 optimal for AEC-Q101–mandated, high-reliability 12V/24V load switching.

FAQ
Is DMN3066LQ-13 suitable for hot-swap applications?
Yes-its 30V VDSS, 21A pulsed drain rating, and fast 11ns fall time enable controlled inrush current limiting during live insertion. Combined with low 67mΩ RDS(ON), it minimizes voltage droop and thermal stress during repeated hot-plug cycles in USB-C and modular industrial interfaces.
What is the maximum allowable PCB trace width for the SOT23 drain pad?
The datasheet specifies a 1-inch² copper area for the 94°C/W thermal rating. For standard 2oz copper, this corresponds to a ~25mm × 25mm thermal pad connected via ≥4 thermal vias (0.3mm diameter) to inner ground planes-no minimum trace width is defined, but traces carrying ≥2A should be ≥0.5mm wide to limit temperature rise to <20°C.
Does DMN3066LQ-13 require a gate resistor for stability?
A 10Ω series gate resistor is recommended per the datasheet's dynamic test condition (RGEN = 10Ω). This value damps ringing caused by gate-drain capacitance (Crss = 42pF) and prevents oscillation when driven by low-impedance sources, especially in high-noise automotive environments.
Can DMN3066LQ-13 replace Si2302DS in existing designs?
Yes-both are SOT23 N-channel MOSFETs with compatible pinout (G-S-D), 30V rating, and 1.5V max VGS(TH). DMN3066LQ-13 offers lower RDS(ON) (67mΩ vs. 90mΩ @ 4.5V) and AEC-Q101 qualification, making it a functional and reliability upgrade for automotive and industrial revisions.
