Product details
Overview
DMTH10H032LFVWQ-7 from Diodes Incorporated is an AEC-Q101-qualified 100V N-channel enhancement-mode MOSFET in PowerDI3333-8 package, delivering 30 mΩ RDS(ON) at VGS = 10 V and 26 A continuous drain current at TC = +25°C. It operates up to +175°C junction temperature and supports automotive backlighting, DC-DC converters, and power-management functions.
For engineers reviewing the DMTH10H032LFVWQ-7 datasheet, DMTH10H032LFVWQ-7 pinout, DMTH10H032LFVWQ-7 application, or DMTH10H032LFVWQ-7 equivalent, key selection criteria include its wettable-flank PowerDI3333-8 package for optical inspection, 100% production-tested UIS robustness, and AEC-Q101 qualification with PPAP support.
Technical Context
This MOSFET uses a trench-gate silicon process optimized for low RDS(ON) and fast switching in high-reliability automotive power stages. Its gate threshold voltage (1.3–2.5 V) enables compatibility with 3.3 V and 5 V logic-level drive, while its 6.3 nC total gate charge at VGS = 4.5 V supports efficient PWM control in compact DC-DC topologies.
The device integrates a body diode with 0.8–1.0 V forward voltage at 6 A and exhibits 94.6 nC reverse recovery charge - critical for synchronous rectification and flyback snubber design. Thermal resistance RθJC = 3.3 °C/W enables direct thermal coupling to PCB copper planes in space-constrained modules.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL100N10F7 | 100 V, 3.2 mΩ RDS(ON), TO-263 package, higher current but larger footprint and no wettable flanks. | Requires manual optical inspection; unsuitable for ultra-thin modules due to height and thermal pad access limitations. | Select when higher current density is needed and board space allows TO-263 mounting with external heatsinking. |
| IXTP110N10T | 100 V, 11 mΩ RDS(ON), TO-220 package, non-AEC-Q101 rated, no PPAP support. | Lacks automotive qualification and change control documentation - limited to industrial or consumer-grade designs. | Choose only for cost-sensitive non-automotive applications where AEC-Q101 compliance is not required. |
Compared with STL100N10F7 and IXTP110N10T, the DMTH10H032LFVWQ-7 uniquely combines AEC-Q101 qualification, wettable flank inspection capability, and PowerDI3333-8's low-profile thermal efficiency - making it optimal for space-constrained, safety-critical automotive power stages where manufacturability and qualification traceability are mandatory.

FAQ
What is the maximum continuous drain current at TC = +100°C?
The DMTH10H032LFVWQ-7 supports 18 A continuous drain current at case temperature +100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits imposed by package RθJC = 3.3 °C/W and silicon safe operating area constraints under sustained conduction.
Does this MOSFET require a gate resistor for automotive PWM operation?
A gate resistor is recommended to dampen ringing caused by parasitic inductance in the gate loop. With 1.2 Ω typical gate resistance and 11.9 nC total gate charge, a 5–10 Ω series resistor ensures controlled 10–20 ns rise/fall times while preventing shoot-through in half-bridge configurations.
Is the body diode suitable for synchronous rectification in DC-DC converters?
Yes - the body diode has 0.8–1.0 V forward voltage at 6 A and 31.5 ns reverse recovery time, enabling use in non-synchronous or quasi-synchronous buck converters. However, for full synchronous rectification, an external Schottky or MOSFET with lower VF and QRR is preferred to minimize conduction and switching losses.
How does the wettable flank feature improve manufacturing yield?
The wettable flank geometry exposes vertical sidewalls of all three terminal types (D, G, S) to solder paste, allowing automated optical inspection (AOI) systems to verify solder fillet formation and joint integrity - reducing field failures from voided or insufficient solder joints in high-vibration automotive assemblies.
