Product details
Overview
DMS3014SFGQ-7 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET with integrated Schottky diode in PowerDI3333-8 package, qualified to AEC-Q101 for automotive use. It delivers 14.5mΩ RDS(ON) at VGS = 10V, 9.5A continuous drain current at TA = +25°C, and features low QRR (8.0nC) and low VSD (0.4V typ.) for high-efficiency DC-DC converter switching stages.
For engineers reviewing the DMS3014SFGQ-7 datasheet, DMS3014SFGQ-7 pinout, DMS3014SFGQ-7 application, or DMS3014SFGQ-7 equivalent, key selection criteria include its monolithic DIOFET architecture, AEC-Q101 qualification, thermal resistance of 63°C/W (with 1-inch² copper), and compatibility with 4.5V gate drive in space-constrained automotive power management designs.
Technical Context
This MOSFET integrates a power MOSFET and Schottky diode on a single die using Diodes Incorporated's patented DIOFET process, eliminating external body diode conduction losses and reducing reverse recovery charge. Its gate threshold voltage (1.0–2.2V) enables robust 4.5V logic-level drive while maintaining low shoot-through risk due to optimized Qg/Qgs ratio (45.7nC total gate charge at 10V).
The device operates across –55°C to +150°C junction temperature range and is rated for 100% UIS (unclamped inductive switching) with 45mJ repetitive avalanche energy. Its PowerDI3333-8 package provides 33% board area reduction versus SO-8 and achieves 7.1°C/W junction-to-case thermal resistance for high-density thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - supports 24V automotive rail systems with margin against transients |
| RDS(ON) | 14.5mΩ @ VGS = 10V - enables <1.4W conduction loss at 9.5A, critical for thermally constrained backlight drivers |
| ID (continuous) | 9.5A @ TA = +25°C - sustains peak load currents in 12V/24V DC-DC buck converters |
| QRR | 8.0nC - reduces switching loss during body diode commutation in synchronous rectifier replacement applications |
| VSD | 0.4V typ. @ IS = 1A - lowers forward conduction loss vs. standard MOSFET body diode (typically >0.8V) |
| RθJA | 63°C/W (with 1″² copper) - allows 2.1W power dissipation at +70°C ambient without forced cooling |
| trr | 12.9ns - minimizes dead-time requirements and improves light-load efficiency in high-frequency (>500kHz) converters |
Pinout & Package
Package: PowerDI3333-8, surface-mount, thermally enhanced 8-pin leadless package with exposed drain paddle; dimensions 3.30mm × 3.30mm × 0.80mm; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 5, 6, 7, 8 | Drain (D) | Seven parallel drain terminals connected to internal die and exposed thermal pad - provide low-inductance, high-current path and primary heat transfer route to PCB |
| 4 | Gate (G) | Single gate input with 1.3Ω typical Rg - enables fast, controlled turn-on/turn-off with minimal gate driver stress |
| - (exposed pad) | Source (S) | Internally connected source terminal tied to bottom-side thermal pad - requires soldered connection to PCB ground plane for electrical and thermal integrity |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic DIOFET integration | Single-die MOSFET + Schottky eliminates discrete diode placement error, reduces layout parasitics, and cuts BOM count by one component |
| Low Qg/Qgs ratio | 45.7nC total gate charge with only 5.0nC gate-source charge - suppresses cross-conduction in half-bridge configurations at >1MHz switching |
| AEC-Q101 qualification & PPAP support | Fully automotive-qualified with documented reliability testing (HTOL, TC, UHAST) - meets Tier-1 supplier sourcing requirements for production programs |
| 100% UIS rated | Withstands unclamped inductive energy up to 45mJ - eliminates need for external snubbers in motor driver or solenoid control circuits |
| Green, halogen-free construction | Meets JESD201A Class 2 whisker resistance and RoHS 2 (2011/65/EU) - compliant for global automotive OEM shipments without material declaration exceptions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3016LFD-7 | 30V, 16.5mΩ @ 10V, PowerDI3333-8, but no integrated Schottky; higher VSD (0.95V) | Lacks monolithic Schottky - requires external diode for synchronous rectification, increasing layout complexity and losses | Select when cost sensitivity outweighs efficiency gain and external diode integration is acceptable |
| IPB120N04S4-02 | 40V, 2.0mΩ @ 10V, TO-263-3, higher current (120A), but larger footprint and no AEC-Q101 documentation | Not AEC-Q101 qualified; lacks PPAP support and automotive reliability data - unsuitable for production vehicle programs | Select only for non-automotive industrial prototypes where ultra-low RDS(ON) justifies larger package and compliance gaps |
Compared with DMN3016LFD-7 and IPB120N04S4-02, DMS3014SFGQ-7 uniquely combines AEC-Q101 qualification, monolithic Schottky integration, and PowerDI3333-8 space efficiency - making it the only option that simultaneously satisfies automotive PPAP, synchronous rectifier loss targets, and PCB area constraints below 12mm².

FAQ
Is DMS3014SFGQ-7 suitable for synchronous rectification in 48V automotive systems?
No. Its 30V VDSS rating limits use to 24V nominal systems with transient margin. For 48V architectures, Diodes offers the DMS3022SFGQ-7 (40V) or AP21917 series, which maintain the same PowerDI3333-8 footprint and DIOFET integration but with higher breakdown voltage.
What is the maximum recommended gate resistor for 1MHz switching?
A 3Ω gate resistor is validated in the datasheet for 1MHz operation with 5.5ns tD(ON) and 24.4ns tR. Using >5Ω increases switching time and conduction loss; <2Ω risks ringing and overshoot due to low Rg (0.26–2.34Ω) and 2296pF Ciss, requiring careful PCB layout with short gate traces.
Does the exposed thermal pad require solder mask opening?
Yes. The datasheet specifies a minimum 3.25mm × 3.25mm solder mask opening over the exposed drain pad to ensure full solder fillet formation and optimal thermal transfer. Omitting this reduces RθJA performance by >25% and risks voiding AEC-Q101 thermal validation.
Can DMS3014SFGQ-7 replace SO-8 MOSFETs without layout changes?
No. Although both are 8-terminal packages, PowerDI3333-8 has different pin mapping (7-drain/1-gate vs. SO-8's 4-drain/1-gate/3-source), smaller footprint (3.3mm² vs. 15mm²), and requires thermal pad soldering. Direct replacement demands PCB redesign, including new pad stack, stencil aperture, and thermal relief patterns.
