Product details

Overview

DMTH8028LFVW-7 from Diodes Incorporated is an 80V, 175°C-rated N-channel enhancement-mode MOSFET in PowerDI3333-8 package, delivering 27A continuous drain current at TC = +25°C, 25mΩ R_DS(ON) @ V_GS = 10V, and 41mΩ @ 4.5V - optimized for high-efficiency DC-DC converters and backlighting power stages.

For engineers reviewing the DMTH8028LFVW-7 datasheet, DMTH8028LFVW-7 pinout, DMTH8028LFVW-7 application, or DMTH8028LFVW-7 equivalent, key selection criteria include its wettable flank package for automated optical inspection, 100% production-tested UIS robustness, and thermal resistance of R_θJC = 4.0°C/W enabling high-density thermal management in space-constrained power designs.

Technical Context

This MOSFET employs a trench-gate silicon process to achieve low R_DS(ON) while maintaining fast switching performance: t_D(ON) = 7.1ns, t_F = 8.6ns, and Q_g = 10.4nC @ V_GS = 10V. Its body diode exhibits t_RR = 28.5ns and Q_RR = 21.7nC under IF = 7.5A, di/dt = 100A/μs conditions.

The device operates across -55°C to +175°C junction temperature range with 12.5A avalanche current (IAS) and 23.4mJ EAS rating at L = 0.3mH. Its PowerDI3333-8/SWP package features exposed drain pad for low thermal resistance and matte tin–annealed terminals compliant with MIL-STD-202 solderability standards.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMTH8028LFVWQ-7	Automotive-grade variant (AEC-Q101 qualified); identical electrical specs and package	Required for automotive OEM designs needing PPAP documentation and extended temperature validation	Select when full automotive qualification and traceability are mandated
DMN3028LFG-7	30V V_DSS, 2.8mΩ R_DS(ON) @ 10V, SOT-23-6 package - lower voltage, higher current density, smaller footprint	Suitable only for ≤12V input applications; not interchangeable due to voltage rating mismatch	Choose for cost-sensitive, low-voltage consumer electronics where 80V capability is unnecessary

Compared with DMTH8028LFVWQ-7, the base part lacks AEC-Q101 certification but offers identical performance and supply chain flexibility; versus DMN3028LFG-7, it trades off voltage headroom for thermal robustness and higher current handling in constrained layouts.

FAQ

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

The DMTH8028LFVW-7 supports 19A continuous drain current at TC = +100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the PowerDI3333-8 package under typical PCB mounting conditions with 2oz copper thermal bias, ensuring safe operation without exceeding TJ = +175°C.

Does this MOSFET require a gate resistor for reliable switching?

A gate resistor is recommended to control dV/dt and prevent oscillation, especially in high-frequency (>500kHz) applications. The device's R_g = 1.1Ω internal gate resistance and Q_g = 10.4nC suggest a 2.7Ω external resistor balances switching speed and EMI, matching the test condition used for t_D(ON) and t_F characterization.

Can DMTH8028LFVW-7 be used in linear regulator configurations?

No - this MOSFET is optimized for switching operation, not linear mode. Its Safe Operating Area (SOA) curve shows limited DC capability: at V_DS = 20V, maximum continuous current drops to ~3A due to thermal constraints. Linear regulation would exceed R_θJA limits and risk thermal runaway without active cooling.

Is the PowerDI3333-8 package compatible with standard reflow profiles?

Yes - the package meets IPC/JEDEC J-STD-020 Level 1 moisture sensitivity and is qualified for lead-free reflow up to 260°C peak temperature. Its matte tin–annealed terminals comply with MIL-STD-202 Method 208, and the suggested pad layout (X3 = 2.600mm, Y2 = 1.650mm) ensures reliable solder joint formation under standard profile ramp-soak-reflow cycles.
