Product details
Overview
DMN3061SW-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in SOT323 package, rated for 30V VDSS, 60 mΩ RDS(ON) @ 10V VGS, and 2.7A continuous drain current at +25°C. It delivers low on-resistance with fast switching (tR = 97 ns, Qg = 3.5 nC), optimized for compact DC-DC converters and power management switches in space-constrained portable electronics.
For engineers reviewing the DMN3061SW-7 datasheet, DMN3061SW-7 pinout, DMN3061SW-7 application, or DMN3061SW-7 equivalent, key selection criteria include its 4.5V gate drive compatibility (RDS(ON) = 100 mΩ), thermal resistance of 254°C/W on FR-4, and AEC-Q101 readiness for automotive-grade power switching where footprint and efficiency are critical.
Technical Context
This MOSFET employs planar silicon technology to balance conduction loss and switching speed, supporting PWM-based regulation in synchronous buck stages and load-switching circuits. Its gate threshold voltage range (0.5–1.8 V) enables reliable turn-on with 3.3V logic-level drivers, while low Ciss (278 pF) and Crss (29 pF) minimize Miller effect and improve gate drive efficiency.
The device operates across –55°C to +150°C junction temperature, with RDS(ON) increasing only 1.8× from 25°C to 125°C at VGS = 10V, ensuring stable performance in thermally demanding environments such as automotive body control modules and industrial sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage before avalanche; supports 24V rail systems with margin. |
| RDS(ON) @ 10V | 60 mΩ - Conduction loss of 432 mW at 2.7A; enables >92% efficiency in 1A–2A DC-DC stages. |
| RDS(ON) @ 4.5V | 100 mΩ - Fully compatible with 3.3V/5V microcontroller GPIOs without level-shifting. |
| Qg | 3.5 nC - Low gate charge reduces driver power and enables <100 ns switching transitions. |
| Ciss | 278 pF - Limits high-frequency oscillation risk and eases EMI filtering design. |
| PD (FR-4) | 0.49 W - Thermal limit on standard PCB; requires minimal copper area for 1.5A continuous operation. |
| TJ Range | –55°C to +150°C - Qualified for under-hood automotive and industrial ambient conditions. |

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 |
|---|---|---|---|
| DMN2004LK-7 | RDS(ON) = 45 mΩ @ 4.5V, but larger SOT23-3 package (3.0 × 1.4 mm); higher Ciss (420 pF). | Better conduction loss, but less suitable for ultra-dense layouts requiring SOT323 footprint. | Select when lower RDS(ON) outweighs board area constraints and thermal budget permits higher Ciss. |
| AO3400A | RDS(ON) = 40 mΩ @ 10V but 120 mΩ @ 4.5V; SOT23-3 package; not AEC-Q101 qualified. | Higher gate threshold variation (1.0–2.5 V) risks incomplete turn-on with marginal 3.3V drivers. | Acceptable for cost-sensitive consumer designs where automotive qualification and tight VGS(TH) tolerance are not required. |
Compared with DMN2004LK-7 and AO3400A, the DMN3061SW-7 uniquely combines SOT323 miniaturization, 100 mΩ RDS(ON) at 4.5V, and AEC-Q101 readiness-making it optimal for automotive and portable systems where footprint, logic-level drive, and reliability must coexist.

FAQ
What is the maximum continuous drain current at +70°C ambient?
The DMN3061SW-7 supports 2.2 A continuous drain current at TA = +70°C with derating from the +25°C rating of 2.7 A. This is specified in the Absolute Maximum Ratings table and assumes operation on a standard FR-4 PCB with minimum recommended pad layout per datasheet Figure 13 thermal model.
Does this MOSFET include an integrated body diode, and what is its forward voltage?
Yes, the DMN3061SW-7 has an inherent parasitic body diode between source and drain. Its typical forward voltage is 0.7 V at IS = 1 A and VGS = 0 V, as measured in the Electrical Characteristics table under "Diode Forward Voltage (VSD)." This diode supports freewheeling in inductive loads and reverse-polarity protection.
Is the DMN3061SW-7 qualified for automotive applications?
The DMN3061SW-7 is manufactured in IATF 16949-certified facilities and meets AEC-Q101 stress test requirements for discrete semiconductors. While not pre-qualified as a full automotive part, Diodes Incorporated confirms it is suitable for automotive body electronics and infotainment power rails when used within its specified operating conditions.
Can this MOSFET be driven directly by a 3.3V microcontroller GPIO?
Yes-the DMN3061SW-7 has a guaranteed gate threshold voltage (VGS(TH)) of ≤1.8 V and delivers 100 mΩ RDS(ON) at VGS = 4.5 V, ensuring full enhancement with 3.3V logic. Its low Qg (3.5 nC) further minimizes required drive strength, making direct GPIO control feasible without external buffers in low-current switching applications.
