Product details

Overview

DMS3014SFGQ-13 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 R_DS(ON) at V_GS = 10V, 9.5A continuous drain current at T_A = +25°C, and features low Q_RR (8.0nC) and low V_SD (0.4–0.55V), enabling high-efficiency DC-DC converter and backlighting power stages.

For engineers reviewing the DMS3014SFGQ-13 datasheet, DMS3014SFGQ-13 pinout, DMS3014SFGQ-13 application, or DMS3014SFGQ-13 equivalent, key selection criteria include its monolithic DIOFET architecture, AEC-Q101 qualification, thermal resistance (R_θJA = 63°C/W with 1"² copper), and 100% UIS-rated ruggedness - all critical for automotive power management reliability.

Technical Context

This MOSFET integrates a power MOSFET and Schottky diode on a single die using Diodes Inc.'s patented DIOFET process, eliminating parasitic body diode conduction losses. Its gate threshold voltage (1.0–2.2V) enables compatibility with 3.3V/5V logic-level drive, while low Crss (120pF) and Q_gd/Q_g ratio suppress shoot-through risk in high-frequency synchronous rectification.

The device operates across –55°C to +150°C junction temperature range and is rated for repetitive avalanche energy (E_AR = 45mJ, L = 0.1mH). Its PowerDI3333-8 package provides 7.1°C/W R_θJC, enabling efficient heat transfer to PCB copper without external heatsinking in space-constrained automotive modules.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	30V - supports 24V automotive rail systems with margin against load-dump transients
R_DS(ON)	14.5mΩ @ V_GS = 10V - reduces conduction loss to ≤1.4W at 9.5A, improving thermal headroom
V_SD	0.4–0.55V @ I_S = 1A - lowers reverse recovery loss vs. standard body diode in buck freewheeling
Q_RR	8.0nC - cuts switching loss during body diode commutation in hard-switched topologies
R_θJA	63°C/W (with 1"² copper) - allows 2.1W continuous dissipation at T_A = +70°C
I_AR	30A - ensures robustness against single-pulse inductive fault events in motor drivers
C_iss	2296–4310pF - enables stable gate drive design with <5.5ns turn-on delay at R_G = 3Ω

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
DMN3016LFD-13	30V, 16mΩ @ 10V, same PowerDI3333-8 package but no integrated Schottky; higher V_SD (1.2V typical)	Lacks low-loss freewheeling capability - unsuitable for synchronous rectification where Q_RR matters	Select only if Schottky integration is unnecessary and cost is primary constraint
DMTH3004LPS-13	30V, 4.0mΩ @ 10V, PowerSO-8 package; higher thermal resistance (R_θJA = 70°C/W) and no AEC-Q101 rating	Higher performance R_DS(ON) but not automotive-qualified; larger footprint increases board area by 3×	Prefer for industrial non-automotive DC-DC where qualification isn't required and lower R_DS(ON) justifies size penalty

Compared with DMN3016LFD-13 and DMTH3004LPS-13, DMS3014SFGQ-13 uniquely combines AEC-Q101 qualification, monolithic Schottky integration, and 14.5mΩ R_DS(ON) in a compact 3.3mm × 3.3mm footprint - making it the only choice for thermally constrained, safety-critical automotive power stages requiring low Q_RR and robust avalanche handling.

FAQ

What is the maximum continuous drain current at 100°C ambient temperature?

At T_A = +100°C, the maximum continuous drain current is 5.8A when mounted on FR-4 with 1-inch square copper plate (per Note 7, PD = 2.1W, R_θJA = 63°C/W). This value is derived from thermal derating curves in the datasheet and assumes no additional heatsinking beyond the specified PCB layout.

Does DMS3014SFGQ-13 require a gate resistor for stability in 500kHz switching applications?

Yes - a 3Ω gate resistor is used in the datasheet's dynamic test conditions (t_D(ON), t_R). For 500kHz operation, a 2.2–4.7Ω resistor is recommended to damp ringing and limit peak gate current, given its Q_g = 45.7nC and C_iss = 4310pF maximum; values outside this range may cause overshoot or slow turn-on.

Can this MOSFET replace a discrete MOSFET + Schottky diode pair in an existing design?

Yes - the monolithic integration matches the electrical behavior of a discrete pair but with reduced layout area, lower parasitic inductance, and guaranteed matching between MOSFET and Schottky parameters. Pin-compatible replacement is possible in PowerDI3333-8 footprints; verify gate drive voltage compatibility (V_GS(TH) = 1.0–2.2V) and adjust gate resistor if needed.

Is the exposed drain paddle electrically connected to pins 5–7?

Yes - the exposed drain paddle is internally connected to pins 5, 6, and 7 (all labeled "Drain" in the pin configuration diagram). It must be soldered to a large copper pour serving as both thermal sink and power node; no isolation is required or permitted per mechanical drawings and thermal test conditions.
