Product details
Overview
DMS3014SFG-7 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET with monolithically integrated Schottky diode (DIOFET), housed in PowerDI3333-8 package. It delivers 13 mΩ RDS(ON) @ VGS = 10 V, 9.5 A continuous drain current at TA = +25°C, and 100% UIS avalanche rating - optimized for high-efficiency DC-DC converters and backlighting power stages.
For engineers reviewing the DMS3014SFG-7 datasheet, DMS3014SFG-7 pinout, DMS3014SFG-7 application, or DMS3014SFG-7 equivalent, key selection criteria include its low 14 mΩ RDS(ON) @ 4.5 V gate drive, 8.0 nC QRR, 2.34 Ω max Rg, and AEC-Q101 qualification - critical for automotive-grade power management where body-diode switching loss and board-area constraints matter.
Technical Context
This MOSFET employs Diodes Incorporated's patented DIOFET process to co-integrate an N-channel MOSFET and Schottky diode on a single die, eliminating discrete body-diode conduction losses. Its 0.4–0.55 V VSD and 12.9 ns tRR directly reduce reverse-recovery energy in synchronous rectification and buck converter freewheeling paths.
The device features a 7.1 °C/W RθJC, enabling thermal coupling to PCB copper planes, and supports 12.2 A pulsed drain current (t < 10 s) under enhanced layout conditions. Gate charge parameters - Qg = 45.7 nC @ 10 V and Qgd/Qg = 6.4% - indicate fast, shoot-through-resistant switching at high frequencies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - maximum blocking voltage for 12 V input rail applications with margin against transients |
| RDS(ON) | 13 mΩ @ VGS = 10 V - enables ≤1.3 W conduction loss at 10 A, critical for thermally constrained DC-DC stages |
| ID (continuous) | 9.5 A @ TA = +25°C - supports >10 W output power in compact buck regulators without forced air |
| QRR | 8.0 nC - reduces body-diode switching loss by >70% vs. standard MOSFETs, improving light-load efficiency |
| VSD | 0.4–0.55 V - low forward drop of integrated Schottky minimizes freewheeling conduction loss in synchronous rectifiers |
| RθJA | 63 °C/W (with 1-inch² copper) - allows 2.1 W power dissipation at ambient, supporting high-density power module layouts |
| Qg | 45.7 nC @ VGS = 10 V - balances gate drive strength and switching speed for 500 kHz–1 MHz operation |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 5, 6, 7, 8 | Drain (D) | Seven parallel drain terminals connected to internal MOSFET channel and Schottky cathode - provides low-inductance, high-current path and thermal conduction to PCB |
| 4 | Gate (G) | Single gate input with 1.3 Ω max Rg - enables stable 10 V gate drive without external series resistance in most PWM controllers |
| Source (S) | Source (S) | Internally tied to Schottky anode - forms common reference for both MOSFET channel and integrated diode; requires low-impedance source trace routing |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET-with-integrated-Schottky applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3016LSD-13 | RDS(ON) = 16 mΩ @ 4.5 V; no AEC-Q101 qualification; QRR = 12.5 nC | Targeted at commercial-grade DC-DC converters only; lacks automotive reliability validation | Select when cost sensitivity outweighs automotive qualification and higher QRR is acceptable |
| DMT3006LPS-13 | RDS(ON) = 6.5 mΩ @ 10 V; TO-252 package; no integrated Schottky; RθJA = 70 °C/W | Requires external Schottky for synchronous rectification; larger footprint and higher thermal resistance | Select when lowest RDS(ON) is primary goal and board space/thermal budget allow TO-252 |

FAQ
Is DMS3014SFG-7 recommended for new designs?
No - Diodes Incorporated explicitly marks DMS3014SFG as "NOT RECOMMENDED FOR NEW DESIGN" in its official datasheet (DS35594 Rev. 7-3). While fully functional and supported for existing production, engineers should evaluate newer alternatives like DMS3014SFGQ (AEC-Q101 automotive variant) or next-generation DIOFETs for new projects to ensure long-term supply and feature alignment.
What is the thermal performance difference between FR-4 with minimum pad and 1-inch² copper layout?
Thermal resistance drops from RθJA = 131 °C/W (minimum pad) to 63 °C/W (1-inch² copper), enabling 2.1 W power dissipation versus 1 W. This 112% increase in thermal capacity allows sustained 9.5 A operation at ambient temperatures up to +70°C without heatsinking - critical for sealed industrial enclosures.
How does the integrated Schottky affect gate drive requirements?
The integrated Schottky does not alter gate drive voltage or timing requirements - VGS(TH) remains 1.0–2.2 V and Qg is unchanged. However, its low VSD (0.4–0.55 V) eliminates reverse-recovery delay, allowing gate drivers to turn on the MOSFET earlier in the dead-time window without shoot-through risk - simplifying timing margin analysis.
Can DMS3014SFG-7 be used in linear regulator applications?
No - its Safe Operating Area (SOA) curve shows DC current limitation of 7.6 A at TA = +70°C, and RDS(ON) increases significantly with junction temperature (1.6× at 150°C). The device is optimized for switching operation; linear use would exceed thermal limits and cause premature failure due to lack of SOA derating for continuous conduction.
