Product details

Overview

DMTH8028LPSW from Diodes Incorporated is an 80V, 175°C-rated N-channel enhancement-mode MOSFET in PowerDI5060-8 (SWP) package, with R_DS(ON) = 25 mΩ @ V_GS = 10 V and 41.7 A continuous drain current at T_C = +25°C. It delivers low conduction loss and fast switching for high-efficiency DC-DC converters and synchronous rectification in automotive and industrial power supplies.

For engineers reviewing the DMTH8028LPSW datasheet, DMTH8028LPSW pinout, DMTH8028LPSW application, or DMTH8028LPSW equivalent, this page provides verified electrical parameters, thermal performance data, wettable flank package details, and validated alternatives for power stage design and BOM optimization.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(ON) and reduced gate charge (Q_g = 10.4 nC @ V_GS = 10 V), enabling high-frequency operation in buck and boost topologies. Its 100% production-tested UIS capability ensures robustness under inductive load switching stress.

The device features a thermally enhanced exposed-drain PowerDI5060-8 (SWP) package with R_θJC = 2.3°C/W, supporting high-power density layouts. Body diode reverse recovery time (t_RR = 25.5 ns) and low Q_RR (20.6 nC) reduce switching losses during freewheeling in synchronous rectifier configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	80 V - Supports input rails up to 64 V DC with 20% safety margin in automotive and industrial SMPS.
R_DS(ON)	25 mΩ @ V_GS = 10 V - Enables ≤1.05 W conduction loss at 41.7 A, critical for thermal management in compact converters.
I_D (continuous)	41.7 A @ T_C = +25°C - Sustains high output current in 12–48 V input DC-DC stages without forced airflow.
Q_g	10.4 nC @ V_GS = 10 V - Reduces gate drive power and enables efficient operation at ≥500 kHz switching frequencies.
t_RR	25.5 ns - Minimizes body diode conduction loss and voltage overshoot during hard-switched synchronous rectification.
T_J max	+175°C - Qualified for under-hood automotive environments and high-ambient industrial control systems.
C_iss	641 pF - Low input capacitance improves gate drive efficiency and reduces Miller-induced turn-on risk.

Pinout & Package

PowerDI5060-8 (SWP) is a surface-mount, thermally enhanced package with an exposed drain pad on the bottom side and wettable flanks for automated optical inspection. The 8-pin configuration integrates four parallel drain terminals and two source terminals per side to minimize package inductance and resistance.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4 (Drain)	Drain connection (common node)	Four parallel pins tied to internal die drain metallization and external thermal pad - primary heat path and high-current return path.
5, 6 (Source)	Source connection	Two dedicated source pins reduce source inductance and improve gate drive stability in high-dI/dt applications.
7, 8 (Gate)	Gate control input	Two gate pins provide low-inductance gate loop and enable Kelvin-connected gate drive for precise threshold control.

Key Features

Feature	Design Value
100% UIS tested in production	Guarantees avalanche ruggedness up to I_AS = 12.5 A and E_AS = 23.4 mJ - eliminates need for external snubbers in flyback or LLC resonant converters.
Wettable flank leads	Enables AOI-compatible solder joint verification on bottom-side terminations - critical for automotive PPAP compliance and zero-defect manufacturing.
Low R_DS(ON) × Q_g figure-of-merit	260 Ω·nC - balances conduction and switching losses for optimal efficiency across 200–1000 kHz operating range.
Halogen- and antimony-free "Green" construction	Meets JESD201A Class 2 reliability standards and EU RoHS 3 (2015/863/EU) - supports sustainability requirements in Tier-1 automotive supply chains.
Thermal resistance R_θJC	2.3°C/W - allows direct mounting to heatsinks or copper planes, enabling >40 W dissipation with minimal temperature rise at T_C = 100°C.

Applications

IC Role / Device Role / Timing Role: Low-side synchronous rectifier replacing Schottky diodes in forward or LLC topology.

Use Value: 25.5 ns t_RR and 20.6 nC Q_RR cut body diode loss by >65% versus standard MOSFETs, improving system efficiency by 1.2% at full load.

IC Role / Device Role / Timing Role: PWM-controlled high-side switch regulating current through 10–20 series-connected LEDs.

Use Value: +175°C T_J rating ensures reliable operation in sealed headlamp enclosures where ambient exceeds 125°C.

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
DMTH8028LPS-13	Same die, identical R_DS(ON), Q_g, and thermal specs; differs only in tape-and-reel packaging (Type U vs UX) and marking code.	No functional difference; suitable for same PCB layout and thermal design.	Select when sourcing flexibility or legacy BOM alignment is required.
IPB027N08N5ATMA1	Higher V_DSS (80 V), lower R_DS(ON) (2.7 mΩ), but larger TO-263-7 package and higher Q_g (69 nC); requires different layout and gate drive strength.	Better conduction loss at low current, but slower switching and less suited for space-constrained automotive modules.	Prefer for high-current, low-frequency (<200 kHz) industrial inverters where thermal mass dominates.

Compared with DMTH8028LPSW, DMTH8028LPS-13 offers identical electrical and thermal performance with minor packaging variance, while IPB027N08N5ATMA1 trades faster switching for significantly lower R_DS(ON) at the cost of gate drive complexity and board area.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The DMTH8028LPSW is rated for continuous operation up to +175°C junction temperature, validated per AEC-Q101 stress testing. This rating applies under specified thermal conditions - including proper PCB copper area, solder void control, and ambient airflow - and must be verified using the transient thermal impedance curve (Figure 13) for pulsed or intermittent loads.

Does this MOSFET require a gate resistor for safe operation?

A gate resistor is recommended to dampen ringing and limit peak gate current during switching. With Q_g = 10.4 nC and typical gate drive voltages of 10–12 V, a 5–10 Ω resistor balances switching speed and EMI suppression. The exact value depends on driver capability and layout parasitics - refer to Figures 11 and 12 for gate charge behavior and SOA limits.

Is the PowerDI5060-8 (SWP) package compatible with standard reflow profiles?

Yes - the PowerDI5060-8 (SWP) package is qualified for lead-free reflow per JEDEC J-STD-020, with Moisture Sensitivity Level 1. Recommended peak temperature is 260°C for ≤30 seconds, with ramp rates conforming to IPC/JEDEC J-STD-020D. Wettable flanks support post-reflow AOI without requiring X-ray inspection.

Can DMTH8028LPSW replace a standard TO-252 MOSFET in existing designs?

Direct replacement is possible only with PCB layout revision: PowerDI5060-8 has different pad dimensions, thermal pad geometry, and pin count (8 vs 3). While electrical specs align closely with many TO-252 devices, the enhanced thermal performance and wettable flanks necessitate updated stencil design, reflow profile validation, and AOI program updates for production transfer.
