Product details
Overview
DMTH4014LPDWQ-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET rated for 40V VDSS, 15 mΩ RDS(ON) @ 10V, and 43.6A continuous drain current at TC = +25°C in PowerDI5060-8 package. It is AEC-Q101 qualified, PPAP-capable, and designed for automotive power-management functions including DC-DC converters and LED backlighting under high-ambient-temperature conditions up to +175°C.
For engineers reviewing the DMTH4014LPDWQ-13 datasheet, DMTH4014LPDWQ-13 pinout, DMTH4014LPDWQ-13 application, or DMTH4014LPDWQ-13 equivalent, this part supports high-reliability automotive designs requiring robust UIS performance, low conduction loss, fast switching (tR = 5.7 ns), and thermally stable operation across -55°C to +175°C junction range.
Technical Context
This dual MOSFET integrates two matched N-channel silicon devices in a single PowerDI5060-8/SWP (Type UXD) package with exposed drain pads for thermal efficiency. Its gate threshold voltage (VGS(TH) = 1.0–3.0 V) enables compatibility with 3.3V and 5V logic-level drive, while low input capacitance (Ciss = 733 pF) and gate charge (Qg = 10.2 nC @ 10V) support high-frequency switching in synchronous buck topologies.
The device features 100% production-tested unclamped inductive switching (UIS) with EAS = 20.5 mJ and IAS = 11.7 A, ensuring ruggedness against transient energy in automotive load-dump and inductive kickback scenarios. Its RDS(ON) remains stable over temperature - normalized to 1.2× at +175°C - enabling predictable thermal design in engine bay or headlamp modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40 V - Maximum drain-source blocking voltage for 12V/24V automotive systems with margin against transients. |
| RDS(ON) @ 10V | 15 mΩ max - Enables ≤0.6W conduction loss at 20A, critical for thermally constrained DC-DC converter PCBs. |
| ID (TC = 25°C) | 43.6 A - Sustains high peak currents in motor drivers or LED boost stages without derating. |
| Qg @ 10V | 10.2 nC - Reduces gate-drive power and enables efficient operation with standard MOSFET drivers (e.g., UCC27531). |
| TJ Range | -55°C to +175°C - Certified for under-hood applications where ambient exceeds 125°C. |
| EAS | 20.5 mJ - Confirmed energy-handling capability during inductive turn-off, eliminating need for external snubbers. |
| RθJC | 3.5°C/W - Low junction-to-case resistance enables direct heatsinking via exposed drain pad on copper plane. |
Pinout & Package
Package: PowerDI5060-8/SWP (Type UXD), surface-mount, thermally enhanced with dual exposed drain pads. Dimensions: 5.15 × 6.40 mm footprint, 1.00 mm height, 0.097 g weight. UL 94V-0 molding compound; matte tin annealed terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| S1 | Source of Channel 1 | Low-side return path for first MOSFET; electrically tied to exposed drain pad D1/D2 for thermal conduction. |
| D1 | Drain of Channel 1 | High-current output node; connected internally to exposed drain pad for minimal thermal resistance. |
| G1 | Gate of Channel 1 | Control input for first channel; requires <3V threshold activation and <10.2nC total charge for full turn-on. |
| S2 | Source of Channel 2 | Independent source terminal for second MOSFET; enables dual-switch configurations (e.g., half-bridge, dual-phase sync buck). |
| D2 | Drain of Channel 2 | Second high-current output; isolated from D1 but shares same thermal pad for simultaneous cooling. |
| G2 | Gate of Channel 2 | Independent control input; matched threshold and timing characteristics to G1 for synchronized switching. |

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 |
|---|---|---|---|
| DMTH4014LSDWQ-13 | Same die, SO-8 package (not thermally enhanced); RθJA = 62.6°C/W vs. 3.5°C/W case-to-junction. | Limited to lower-power applications (<10W dissipation); unsuitable for under-hood mounting without heatsink. | Select only when board space allows SO-8 footprint and thermal budget permits higher junction rise. |
| IPB80N04S4-02 | Single-channel 40V TrenchMOS; 2.0 mΩ RDS(ON) but larger TO-263 package; no AEC-Q101 documentation provided. | Requires two discrete devices for dual functionality; lacks integrated dual-channel timing matching. | Use only if ultra-low RDS(ON) is prioritized over integration, footprint, and automotive qualification assurance. |
Compared with DMTH4014LPDWQ-13, the DMTH4014LSDWQ-13 sacrifices thermal performance for legacy SO-8 compatibility, while IPB80N04S4-02 offers lower on-resistance but introduces layout complexity, qualification uncertainty, and no inherent channel matching - making the PowerDI5060-8 dual device optimal for space- and reliability-critical automotive power stages.

FAQ
Is DMTH4014LPDWQ-13 suitable for 3.3V logic-level gate drive?
Yes. With VGS(TH) ranging from 1.0 V to 3.0 V and RDS(ON) = 25 mΩ max at VGS = 4.5 V, it fully enhances using standard 3.3V microcontroller outputs. Gate charge of 5.2 nC at 4.5V ensures fast, low-power switching without external level shifters.
What is the thermal performance difference between PowerDI5060-8 and SO-8 packages?
PowerDI5060-8 delivers RθJC = 3.5°C/W due to its exposed dual drain pad, whereas SO-8 equivalents like DMTH4014LSDWQ-13 have RθJA = 62.6°C/W on FR-4. This enables >10× higher power dissipation in the same PCB area without heatsinks, critical for automotive under-hood use.
Does DMTH4014LPDWQ-13 include body diode specifications?
Yes. The integrated body diode has VSD = 0.9–1.2 V at IS = 20 A and tRR = 11.9 ns at dI/dt = 400 A/μs. These values support synchronous rectification and freewheeling in buck and flyback topologies without external Schottky diodes.
How is AEC-Q101 qualification verified for this part?
Diodes Incorporated subjects DMTH4014LPDWQ-13 to full AEC-Q101 stress tests including HTGB, HTRB, TC, UHAST, and UIS, with production lot testing per PPAP requirements. Qualification data, test reports, and failure analysis records are available upon request for automotive program validation.
