Product details
Overview
DMTH4014LDVWQ from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET rated for 40V VDSS, 15 mΩ RDS(ON) @ 10V VGS, and 27.5A ID at TC = +25°C, housed in a wettable-flank POWERDI® 3333-8 package. It is AEC-Q101 qualified, PPAP-capable, and designed for high-reliability automotive power stages including wireless charging transmitters and synchronous rectification in DC-DC converters.
For engineers reviewing the DMTH4014LDVWQ datasheet, DMTH4014LDVWQ pinout, DMTH4014LDVWQ application, or DMTH4014LDVWQ equivalent, this part supports high-temperature operation up to +175°C, delivers low conduction loss with 12.8 mΩ typical RDS(ON), and features 100% production-tested UIS robustness - critical for automotive load switching and power management design validation.
Technical Context
This dual N-channel MOSFET integrates two matched silicon die in a single POWERDI® 3333-8/SWP (Type UXD) thermally enhanced package, enabling compact half-bridge or dual-switch configurations. Its gate threshold voltage (1–3 V) and low input capacitance (750 pF Ciss) support fast, efficient PWM control at 10V or 4.5V logic levels.
The device exhibits stable RDS(ON) over temperature (±15% variation from −55°C to +175°C at VGS = 10V), and its 7.8°C/W RθJC enables direct thermal coupling to PCB copper planes. Body diode recovery (tRR = 11.3 ns, QRR = 9.5 nC) is optimized for synchronous rectification in high-frequency buck and boost topologies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH4014LSDQ-7 | Same silicon die, but in SO-8 package with standard gull-wing leads; no wettable flanks; RθJA = 62°C/W (vs. 57.5°C/W for POWERDI) | Lacks AOI-compatible terminations; unsuitable for high-reliability automotive SMT lines requiring solder-joint inspection | Select only if legacy SO-8 footprint compatibility is required and thermal margin permits higher RθJA |
| IPB80N04S4-02 | Single-channel 40V TrenchMOS, 2.0 mΩ RDS(ON), TO-263 package; higher current (80A), no AEC-Q101 qualification | Not dual-channel; requires two devices for same functionality; lacks PPAP documentation and automotive change control | Use only in non-automotive industrial applications where cost-per-amp dominates and qualification is not mandated |
Compared with DMTH4014LDVWQ, the DMTH4014LSDQ-7 sacrifices AOI capability and thermal performance for legacy packaging, while the IPB80N04S4-02 offers lower RDS(ON) but fails to meet automotive qualification, dual-channel integration, or wettable flank requirements - making DMTH4014LDVWQ the sole fit for AEC-Q101-compliant dual-switch designs with production-grade inspection.

FAQ
What is the maximum allowable gate-source voltage for DMTH4014LDVWQ?
The absolute maximum VGS is ±20 V per the datasheet's Maximum Ratings table. Operation beyond ±20 V risks permanent gate oxide damage. For reliable 4.5V logic-level drive, a 12V gate supply with active clamping or Zener limiting is recommended to maintain margin against transient overshoot.
Does DMTH4014LDVWQ support parallel operation of its two channels?
Yes - both channels share identical electrical characteristics (RDS(ON), VGS(TH), Qg) and thermal coupling via the common package substrate. Parallel use is supported for increased current capacity, provided gate drive impedance and PCB layout symmetry ensure balanced current sharing.
How is the wettable flank feature implemented in the POWERDI® 3333-8/SWP package?
The package exposes vertical sidewalls of the copper leadframe along all four edges, plated with matte tin annealed over copper. This allows solder to wick up the side surfaces during reflow, forming visible fillets that automated optical inspection systems can validate for solder joint integrity and coplanarity.
Can DMTH4014LDVWQ replace a single-channel MOSFET in an existing design?
It can replace one channel when used as a drop-in single-switch, but its dual-channel architecture is best leveraged in new designs requiring space-constrained half-bridge or dual-load configurations. Unused channel must be properly terminated (gate tied to source, drain floating or tied to safe potential) to avoid unintended conduction.
