Product details
Overview
DMN3061SQ-13 from Diodes Incorporated is an AEC-Q101 qualified N-channel enhancement-mode MOSFET in SOT23 package, rated for 30V VDSS, 59 mΩ RDS(ON) @ 10VGS, and 2.9A continuous drain current at +25°C. It serves as a low-side power switch in automotive body electronics, including LED lighting control and sensor interface circuits.
For engineers reviewing the DMN3061SQ datasheet, DMN3061SQ pinout, DMN3061SQ application, or DMN3061SQ equivalent, key selection criteria include its 4.5V gate drive compatibility, 98 mΩ RDS(ON) at 4.5VGS, AEC-Q101 qualification, thermal resistance of 161 °C/W (FR-4, min pad), and SOT23 footprint constraints.
Technical Context
This MOSFET employs planar trench-gate technology optimized for low gate charge (5.5 nC @ 10VGS) and fast switching (tr = 2.8 ns, tf = 2.4 ns), enabling efficient operation in high-frequency DC-DC converter synchronous rectification and load-switching topologies.
Its gate threshold voltage range (0.5–1.8 V) ensures reliable turn-on with 3.3V and 4.5V logic-level drivers, while the integrated body diode (VSD = 0.7–1.0 V @ 1A) supports bidirectional current handling in reverse-polarity protection and H-bridge half-bridge configurations.

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 |
|---|---|---|---|
| DMN3025LSD-13 | Lower RDS(ON) (25 mΩ @ 10VGS), higher Qg (12.5 nC), same SOT23 package | Better conduction efficiency but slower switching; less suitable for >500 kHz PWM | Select when thermal budget dominates over switching frequency constraints. |
| NTMFS4C02P8T1G | Higher ID (12.5A), SO-8FL package, 2.2 mΩ RDS(ON) @ 10VGS, not AEC-Q101 qualified | Requires PCB redesign; lacks automotive qualification and PPAP support | Use only in non-automotive industrial designs where footprint flexibility and higher current are prioritized. |
Compared with DMN3061SQ-13, DMN3025LSD-13 trades faster switching for lower conduction loss in static loads, while NTMFS4C02P8T1G offers superior current handling but forfeits automotive compliance and SOT23 compatibility-making DMN3061SQ the optimal balance for space- and qualification-constrained automotive switches.

FAQ
Is DMN3061SQ-13 suitable for 3.3V microcontroller GPIO drive?
Yes. With a gate threshold voltage range of 0.5–1.8 V and guaranteed RDS(ON) of 196 mΩ at VGS = 3.3V, the DMN3061SQ-13 turns on fully using standard 3.3V logic outputs. Its 5.6 Ω gate resistance and low 2.9 nC Qg @ 4.5V ensure minimal drive strength requirements and fast edge rates without external buffering.
What is the maximum safe operating temperature for continuous 2.3A drain current?
At 2.3A continuous drain current and ambient temperature of +70°C, the junction temperature reaches approximately +145°C assuming RθJA = 101 °C/W (with 1-inch² copper plate). This remains within the rated –55°C to +150°C operating range. Derating is required above +70°C ambient to maintain TJ ≤ +150°C.
Does DMN3061SQ-13 include built-in ESD protection?
No. The DMN3061SQ-13 does not integrate dedicated ESD protection circuitry. Its gate oxide is rated for ±20V VGSS, and it complies with HBM ESD classification per AEC-Q101 (≥2 kV), but external TVS or RC filtering is recommended for board-level ESD immunity in automotive harness interfaces.
Can DMN3061SQ-13 be used in parallel configurations?
Parallel operation is not recommended due to positive temperature coefficient of RDS(ON) being insufficient to ensure current sharing across devices. Variations in VGS(TH) (0.5–1.8 V) and dynamic gate charge cause unequal turn-on timing and potential thermal runaway without individual gate resistors and matched layout.
