Product details
Overview
DMTH8028LFVWQ-7 from Diodes Incorporated is an AEC-Q101-qualified 80V N-channel enhancement-mode MOSFET in PowerDI3333-8 package, delivering 27A continuous drain current at TC = +25°C, 25mΩ RDS(ON) @ VGS = 10V, and 175°C maximum junction temperature. It is engineered for automotive power-management functions including DC-DC converters and LED backlighting.
For engineers reviewing the DMTH8028LFVWQ-7 datasheet, DMTH8028LFVWQ-7 pinout, DMTH8028LFVWQ-7 application, or DMTH8028LFVWQ-7 equivalent, key selection criteria include its wettable flank package for automated optical inspection, 100% production-tested UIS robustness, and thermal resistance of 4.0°C/W (junction-to-case) under high-density layout constraints.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) and fast switching in automotive-grade 12V/24V systems. Its gate threshold voltage (1.3–2.5V) enables reliable turn-on with standard logic-level drivers, while Crss of 19.5pF and Qgd of 2.4nC support efficient hard-switching in synchronous buck topologies.
The device integrates a robust body diode with tRR = 28.5ns and QRR = 21.7nC, enabling stable freewheeling in bidirectional power stages. Its SOA is rated up to 100ms at 80V/10A with TJ limited to 175°C, validated under single-pulse conditions on infinite heatsink simulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 80V - Withstands peak system transients in 24V automotive rails without avalanche breakdown |
| RDS(ON) | 25mΩ @ VGS = 10V - Enables <1.5W conduction loss at 27A, critical for thermally constrained modules |
| ID (max) | 27A @ TC = +25°C - Supports high-current power stages in compact DC-DC converters |
| TJ(max) | +175°C - Meets under-hood temperature requirements per AEC-Q101 Grade 0 |
| RθJC | 4.0°C/W - Confirms effective heat transfer from die to exposed drain pad in PowerDI3333-8 |
| Qg | 10.4nC @ VGS = 10V - Determines gate drive power and switching speed in 200–500kHz applications |
| tRR | 28.5ns - Limits reverse recovery losses and EMI in synchronous rectification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH8028LSDQ-7 | Same die, SO-8 package (no wettable flank, RθJA = 62°C/W) | Lacks AOI capability; unsuitable for automotive PPAP where optical inspection is mandated | Select only for non-automotive industrial use with relaxed inspection requirements |
| IPB80N04S4-02 | 40V VDSS, 2.0mΩ RDS(ON), TO-263 package, no AEC-Q101 | Lower voltage rating limits use to 12V-only systems; lacks automotive qualification and PPAP support | Consider only for cost-sensitive 12V consumer applications with no functional safety needs |
Compared with DMTH8028LSDQ-7 and IPB80N04S4-02, the DMTH8028LFVWQ-7 uniquely combines AEC-Q101 qualification, wettable flank inspection, and 80V/25mΩ performance in a thermally efficient 3.3×3.3mm footprint-making it the sole choice for PPAP-compliant automotive power stages requiring both reliability and manufacturability assurance.

FAQ
What is the maximum allowable gate-source voltage for DMTH8028LFVWQ-7?
The absolute maximum gate-source voltage is ±20V. Exceeding this rating risks permanent gate oxide damage. For reliable operation, gate drive circuits must clamp VGS within –12V to +15V during transients, especially in noisy automotive environments where load-dump spikes may couple into gate traces.
Does DMTH8028LFVWQ-7 support synchronous rectification in buck converters?
Yes-it is qualified for synchronous rectification with a body diode tRR of 28.5ns and QRR of 21.7nC. Its low Crss (19.5pF) minimizes shoot-through risk when paired with complementary high-side drivers, and its 10.4nC total gate charge enables clean 500kHz switching with standard 1A peak gate drivers.
How does the PowerDI3333-8 package improve thermal performance over SO-8?
The PowerDI3333-8 exposes the drain directly to the PCB via a large bottom-side copper pad, achieving RθJC = 4.0°C/W-over 40% lower than typical SO-8 packages. Its 3.3×3.3mm footprint also allows tighter layout spacing, reducing parasitic inductance in high-frequency power paths.
Is DMTH8028LFVWQ-7 suitable for hot-swap applications?
No-it lacks integrated current limiting, thermal shutdown, or soft-start circuitry required for safe hot-swap insertion. While its 100% UIS testing supports transient inductive stress, controlled hot-swap requires external current-sense amplifiers and gate-control logic not provided by this discrete MOSFET.
