Product details
Overview
DMT10H032LFDF-7 from Diodes Incorporated is a 100V N-channel enhancement-mode MOSFET in U-DFN2020-6 (Type F) package, delivering 32mΩ RDS(ON) at VGS = 10V and 6A continuous drain current at TA = +25°C. It features 100% production-tested UIS robustness, 0.6mm profile, and 4mm² PCB footprint-optimized for compact, high-efficiency power switching in battery-operated systems and solid-state relays.
For engineers reviewing the DMT10H032LFDF-7 datasheet, DMT10H032LFDF-7 pinout, DMT10H032LFDF-7 application, or DMT10H032LFDF-7 equivalent, key selection criteria include its low-profile U-DFN2020-6 thermal performance (RθJA = 75.2°C/W with 1-inch² copper), 4.5V logic-level gate drive capability, and validated avalanche energy (EAS = 25.3mJ).
Technical Context
This MOSFET employs a trench-gate silicon process optimized for simultaneous low RDS(ON) and fast switching. Its gate threshold voltage (1.3–2.5V) enables reliable turn-on with 3.3V/4.5V microcontroller outputs, while Crss of 6.9pF and Qgd of 3.1nC support efficient hard-switching operation up to several hundred kHz.
The device integrates a low-VSD body diode (0.8–1.0V at 6A) with tRR = 31.5ns and QRR = 94.6nC, enabling synchronous rectification and bidirectional current handling in half-bridge configurations without external Schottky supplementation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 100V - supports 48V industrial bus and 60V automotive load-switch applications with margin |
| RDS(ON) | 32mΩ @ VGS = 10V - limits conduction loss to ≤1.15W at 6A DC, critical for thermally constrained PCBs |
| ID (max) | 6A @ TA = +25°C - enables direct drive of solenoids, relays, and LED arrays without heatsinking |
| Qg | 11.9nC @ VGS = 10V - determines gate driver current requirement (~12mA avg for 1MHz switching) |
| EAS | 25.3mJ - ensures survivability during inductive load turn-off transients (e.g., motor coils, relay coils) |
| RθJA | 75.2°C/W (with 1″² copper) - allows ~1.1W dissipation before exceeding 125°C junction limit at 25°C ambient |
| tRR | 31.5ns - minimizes reverse recovery losses in synchronous buck or half-bridge topologies |
Pinout & Package
U-DFN2020-6 (Type F) is a 2.0mm × 2.0mm × 0.6mm leadless surface-mount package with exposed drain pad for thermal enhancement and six terminals arranged in dual-row configuration. Pin 1 is marked by chamfered corner per Diodes Inc. standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Source terminal (S) | Low-side return path; connects to ground or low-voltage rail in common-source switch |
| 2 (Gate) | Gate terminal (G) | Control input; requires <2.5V threshold margin for reliable 3.3V MCU drive |
| 3 (Drain) | Drain terminal (D) | High-side connection to load; electrically tied to exposed thermal pad |
| 4 (Drain) | Drain terminal (D) | Second drain connection; parallel path to reduce package inductance and improve thermal spreading |
| 5 (Source) | Source terminal (S) | Secondary source connection; reduces source loop inductance for improved EMI and switching stability |
| 6 (Source) | Source terminal (S) | Third source connection; enhances current sharing and solder joint reliability under thermal cycling |
Key Features
| Feature | Design Value |
|---|---|
| 0.6mm profile | Enables integration into ultra-thin portable electronics (e.g., wearables, IoT sensors) where height clearance <0.7mm is mandatory |
| 100% UIS tested | Guarantees minimum 25.3mJ single-pulse avalanche energy across 100% production units-no screening required for ruggedized designs |
| 4mm² footprint | Reduces PCB area by >50% vs. SO-8 equivalents while maintaining comparable RDS(ON) and thermal resistance |
| Lead-free & halogen-free | Complies with RoHS 3 (2015/863/EU) and JEDEC J-STD-020 Level 1 moisture sensitivity-eliminates reflow concerns and supports green manufacturing |

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 |
|---|---|---|---|
| DMT10H032LPSQ-7 | Same die, PQFN-2020-6 package with larger thermal pad and different pinout (3-drain/3-source symmetry) | Higher thermal performance (RθJA = 62°C/W) but requires revised PCB layout | Select when board-level thermal budget is tighter than 1.1W and layout revision is feasible |
| DMTH10H032LFD-7 | Same RDS(ON), but in U-DFN2020-6 (Type D) with non-exposed drain pad and lower UIS rating (EAS = 18.5mJ) | Lower cost but unsuitable for unclamped inductive loads without external protection | Select only for resistive or lightly inductive loads where avalanche stress is absent |
Compared with DMT10H032LPSQ-7, this part trades thermal margin for drop-in compatibility; compared with DMTH10H032LFD-7, it delivers superior ruggedness at identical footprint-making it optimal for safety-critical load switching where layout changes are prohibited.

FAQ
What is the maximum continuous drain current at 70°C ambient?
The DMT10H032LFDF-7 supports 5A continuous drain current at TA = +70°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the U-DFN2020-6 package on standard FR-4 with 2oz copper; performance improves to 6A with enhanced copper area per Note 6.
Does this MOSFET require a gate resistor for 3.3V MCU drive?
No external gate resistor is required for basic turn-on with 3.3V microcontrollers, as VGS(TH) ranges from 1.3V to 2.5V and typical Rg is 1.2Ω. However, a 10–22Ω series resistor is recommended to dampen ringing and control dV/dt during fast switching in noise-sensitive environments.
Is the exposed drain pad electrically connected to the drain terminals?
Yes-the exposed thermal pad on the bottom of the U-DFN2020-6 (Type F) package is internally connected to the drain (D) terminals (pins 3 and 4). It must be soldered to a large copper pour tied to the drain net for optimal thermal and electrical performance.
Can this MOSFET replace a TO-252 DPAK device in existing designs?
It can replace TO-252 devices functionally but not mechanically-U-DFN2020-6 has 2.0×2.0mm footprint versus TO-252's 6.5×6.2mm, requiring full PCB redesign. Thermal performance differs significantly: RθJA is 75.2°C/W (with 1″² copper) vs. ~60°C/W for TO-252, so power handling must be re-evaluated per layout.
