Product details
Overview
DMN6075SQ-7 from Diodes Incorporated is a 60V N-channel enhancement-mode MOSFET in SOT23 package, qualified to AEC-Q101 for automotive use. It delivers 2.5A continuous drain current at VGS = 10V, 85mΩ RDS(ON), and fast switching with 12.3nC total gate charge - enabling high-efficiency DC-DC converters and power management circuits in space-constrained automotive modules.
For engineers reviewing the DMN6075SQ-7 datasheet, DMN6075SQ-7 pinout, DMN6075SQ-7 application, or DMN6075SQ-7 equivalent, key selection criteria include its AEC-Q101 qualification, low RDS(ON) at 4.5V (120mΩ), thermal resistance of 110°C/W with thermal vias, and suitability for backlighting and load-switching in harsh-temperature automotive environments.
Technical Context
This MOSFET operates as a single N-channel power switch with gate threshold voltage between 1V and 3V, enabling compatibility with 3.3V and 5V logic-level drive. Its body diode exhibits 0.8–1.2V forward voltage at 2.5A, supporting synchronous rectification and flyback recovery.
The device's dynamic characteristics include Ciss = 606pF, Coss = 32.6pF, and Crss = 24.6pF at VDS = 20V, contributing to predictable turn-on/turn-off timing (tD(ON) = 3.5ns, tF = 11ns) under 20Ω gate resistance and 30V drain conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60V - supports input rails up to 48V automotive systems with margin against transients |
| RDS(ON) | 85mΩ @ VGS = 10V - enables <170mW conduction loss at 2.5A, critical for thermally limited SOT23 layouts |
| ID (max) | 2.5A @ TA = +25°C - defines maximum steady-state load capability on standard FR-4 with thermal vias |
| Qg | 12.3nC @ VGS = 10V - determines gate driver current requirement and switching energy loss |
| RθJA | 110°C/W - specifies junction-to-ambient thermal resistance with optimized PCB layout (2oz copper + thermal vias) |
| VGS(TH) | 1–3V - ensures reliable turn-on with 3.3V microcontroller GPIO without level-shifting |
| Ciss | 606pF - impacts high-frequency gate drive impedance and EMI behavior in switching nodes |
Pinout & Package
SOT23-3 package: compact surface-mount outline with 2.9mm × 1.3mm footprint, 0.008g mass, and UL 94V-0 molded green compound. Moisture sensitivity level 1 per J-STD-020.

| 2 (Gate) | Control terminal for channel conduction | High-impedance input requiring <12.3nC charge for full enhancement; sensitive to ESD |
| 3 (Drain) | Power input/output node | Handles 60V blocking and 2.5A conduction; connects to switched rail or inductive load |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive temperature range (−55°C to +150°C) and PPAP-ready manufacturing |
| Low RDS(ON) at 4.5V | 120mΩ enables direct drive from 5V MCUs without gate boosting in power management functions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN6075SFG-7 | Same die, but in SOT23-6 package with separate Kelvin source pin | Enables accurate current sensing and reduced gate-drain coupling in precision power stages | Select when layout allows larger footprint and measurement accuracy outweighs size constraints |
| NTMFS4C06NT1G | 60V, 3.2A, 52mΩ @ 10V; SO-8FL package; higher current, lower RDS(ON), larger thermal mass | Better suited for >2.5A loads and sustained 1W dissipation without thermal derating | Choose for non-space-constrained industrial or commercial designs needing higher current headroom |
Compared with DMN6075SQ-7, DMN6075SFG-7 offers improved gate control fidelity at the cost of board area, while NTMFS4C06NT1G trades miniaturization for higher current capacity and thermal robustness - making the DMN6075SQ-7 optimal for AEC-Q101-compliant, size-sensitive automotive modules below 2.5A.

FAQ
Is DMN6075SQ-7 suitable for high-frequency switching above 1MHz?
No - while its 3.5ns turn-on delay and 11ns fall time support operation up to ~500kHz, the 606pF input capacitance and 110°C/W thermal resistance make it unsuitable for stable 1MHz+ operation without significant derating. For >1MHz applications, consider devices with lower Ciss and enhanced thermal performance such as the DMN3029LSD-13.
Does DMN6075SQ-7 require a gate resistor for automotive ESD protection?
Yes - although not internally protected, its gate oxide is rated for ±20V, and automotive environments demand external series gate resistance (typically 10–47Ω) plus TVS clamping to suppress ISO 10605 transients. The 1.5Ω intrinsic gate resistance helps damp ringing but does not replace external protection.
Can DMN6075SQ-7 be used in high-side switch configurations?
Yes - it can function as a high-side switch when driven by a bootstrap or charge-pump gate driver that supplies VGS ≥ 10V relative to the source. However, its 3V max VGS(TH) and lack of integrated level-shifting require careful driver selection to ensure full enhancement during cold-cranking (6V battery).
What is the maximum allowable PCB copper area for thermal vias with DMN6075SQ-7?
Per Diodes' recommended layout, up to 12 thermal vias (0.3mm diameter, 0.5mm pitch) connecting the drain pad to a 1-inch² internal or bottom-layer copper pour reduce RθJA from 157°C/W to 110°C/W. Exceeding this count yields diminishing returns due to via thermal resistance saturation and solder wicking risks.
