Product details

Overview

DMT3008LFDF-7 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET in U-DFN2020-6 package, featuring 10mΩ R_DS(ON) at V_GS = 10V, 12.0A continuous drain current at T_A = +25°C, and low 1.0–3.0V gate threshold voltage. It serves as a high-efficiency power switch in compact DC-DC converters and load switching circuits.

For engineers reviewing the DMT3008LFDF-7 datasheet, DMT3008LFDF-7 pinout, DMT3008LFDF-7 application, or DMT3008LFDF-7 equivalent, key selection criteria include its 10mΩ on-resistance at 10V drive, 4.5V logic-level compatibility, 0.6mm profile for space-constrained PCBs, and AEC-Q101 readiness for automotive-grade reliability validation.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(ON) while preserving fast switching performance: t_D(ON) = 3.8ns, t_F = 3.6ns, and Q_g = 14nC at V_GS = 10V. Its body diode exhibits V_SD = 1.2V at I_S = 2A and t_RR = 18.4ns under 100A/μs dI/dt.

The device operates across –55°C to +150°C junction temperature range, with R_θJA = 60.8°C/W (with 1-inch² copper pad) and R_θJC = 13°C/W. Its U-DFN2020-6 (Type F) package enables high thermal efficiency in ultra-thin applications without exposed thermal pad.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel MOSFET switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN3016LFG-7	R_DS(ON) = 16mΩ @ 4.5V (vs. 16mΩ), same U-DFN2020-6 package, but higher Q_g = 17nC	Marginally lower efficiency in 3.3V-driven PWM circuits due to higher gate charge	Select when cost sensitivity outweighs 15% higher switching loss at 1MHz
AO3400A	SO-23 package (3.0mm × 1.4mm), R_DS(ON) = 28mΩ @ 4.5V, higher R_θJA = 170°C/W	Requires larger PCB area and derating above 65°C ambient; not suitable for ultra-thin designs	Choose only if legacy SO-23 footprint compatibility is mandatory

Compared with DMN3016LFG-7 and AO3400A, DMT3008LFDF-7 delivers superior power density (4mm² vs. 4.2mm² and 4.2mm²), lowest R_DS(ON) at both 4.5V and 10V, and best thermal performance in space-limited industrial and automotive modules.

FAQ

What is the maximum safe operating temperature for DMT3008LFDF-7?

The device supports junction temperatures from –55°C to +150°C. With a thermal resistance of 60.8°C/W (on 1″² copper), it can sustain 1.3W power dissipation at +70°C ambient before reaching T_J = 150°C. Derating is required above 70°C ambient per the datasheet's R_θJA curve.

Does DMT3008LFDF-7 require a gate resistor for stability?

Yes - a 4.7Ω gate resistor is used in the datasheet's switching characterization (t_D(ON), t_F). This value suppresses ringing caused by gate-drain capacitance (Crss = 53pF) and parasitic inductance. For 3.3V MCU drive, a 10Ω resistor is recommended to limit peak gate current and prevent overshoot.

Can DMT3008LFDF-7 be used in automotive applications?

While not pre-qualified to AEC-Q101, Diodes states this part is manufactured in IATF 16949-certified facilities and supports PPAP documentation. Customers must perform their own stress testing per AEC-Q101 Rev D; the 150°C T_J(max), 30V V_DSS, and robust package make it suitable for under-dash BCM and lighting modules.

How does the U-DFN2020-6 package affect solder reflow yield?

The U-DFN2020-6 (Type F) has no exposed thermal pad and uses NiPdAu plating compatible with standard SnAgCu reflow profiles. Diodes specifies J-STD-020 Level 1 moisture sensitivity, eliminating bake requirements. Recommended stencil aperture is 0.12mm thick with 1:1 opening to avoid bridging on 0.65mm pitch.
