Product details
Overview
DMTH4014LPD-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in PowerDI5060-8 (Type C) package, rated for 40V VDSS, 15mΩ RDS(on) @ 10VGS, and 43.6A continuous drain current at TC = +25°C. It operates up to +175°C junction temperature and supports high-efficiency DC-DC converters, backlighting, and power management functions where low conduction loss and robust UIS performance are critical.
For engineers reviewing the DMTH4014LPD-13 datasheet, DMTH4014LPD-13 pinout, DMTH4014LPD-13 application, or DMTH4014LPD-13 equivalent, key selection criteria include RDS(on) at 4.5VGS (25mΩ max), 100% production-tested UIS capability, thermal resistance RθJC of 3.5°C/W, dual-channel layout for space-constrained synchronous rectification, and AEC-Q101 readiness for automotive-adjacent industrial designs.
Technical Context
This dual N-channel MOSFET integrates two matched silicon die in a single exposed-drain thermally enhanced PowerDI5060-8 package, enabling synchronous buck converter topologies with shared gate drive and minimized PCB footprint. Its 175°C-rated silicon ensures stable operation under sustained thermal stress in enclosed power modules.
The device features low input capacitance (Ciss = 733pF) and fast switching (tR = 5.7ns, tF = 1.8ns), optimized for high-frequency (>500kHz) DC-DC conversion. Body diode recovery (tRR = 11.9ns, QRR = 9.28nC) supports efficient hard-switched and quasi-resonant applications without external Schottky supplementation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40V - Maximum blocking voltage before avalanche; suitable for 24V nominal input systems with 50% transient margin. |
| RDS(on) @ 10VGS | 15mΩ max - Enables ≤1.5W conduction loss at 43.6A, critical for thermally constrained 12–24V power stages. |
| RDS(on) @ 4.5VGS | 25mΩ max - Ensures usable channel enhancement with standard 5V logic-level gate drivers in compact DC-DC designs. |
| TJ max | +175°C - Allows direct mounting on hot surfaces (e.g., motor control heatsinks) without derating in industrial environments. |
| UIS Rating | 100% production tested - Guarantees robustness against inductive energy spikes in solenoid drivers and motor phase-legs. |
| RθJC | 3.5°C/W - Enables direct thermal coupling to copper pour or heatsink, supporting >35W dissipation with minimal ΔT. |
| Qg @ 10V | 10.2nC - Low gate charge reduces driver power loss and simplifies gate drive design for high-frequency PWM. |
Pinout & Package
Package: PowerDI5060-8 (Type C), surface-mount, thermally enhanced with exposed drain pad (pins D1/D2 tied internally to thermal pad). Molded green compound, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| S1 | Source of Channel 1 | Low-side return path for first MOSFET; electrically isolated from S2 unless externally connected. |
| D1 | Drain of Channel 1 | Connected to exposed thermal pad; primary current path into channel 1; requires full-solder coverage for thermal integrity. |
| G1 | Gate of Channel 1 | High-impedance control terminal; driven by dedicated gate driver or controller output for independent switching. |
| S2 | Source of Channel 2 | Independent source node for second MOSFET; enables dual-phase or complementary topology implementation. |
| D2 | Drain of Channel 2 | Second exposed-drain connection; shares same thermal pad as D1 but electrically isolated; supports parallel or half-bridge use. |
| G2 | Gate of Channel 2 | Separate gate input allowing asynchronous or synchronized control of second channel without crosstalk. |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Automotive LED Headlamp Driver | Industrial DC-DC Buck Converter |
|---|---|
Use Scenario: High-brightness LED arrays powered from 24V vehicle battery with PWM dimming and overvoltage protection. IC Role / Device Role / Timing Role: Dual-channel synchronous rectifier and high-side switch in buck-boost architecture; handles 30A peak load current per channel. Use Value: 15mΩ RDS(on) minimizes heat generation in confined headlamp housing; 175°C rating prevents thermal shutdown during prolonged high-beam operation. | Use Scenario: 48V-to-12V intermediate bus converter in programmable logic controller (PLC) backplane. IC Role / Device Role / Timing Role: Primary power switch pair in interleaved synchronous buck stage operating at 300kHz with 180° phase shift. Use Value: Matched dual die ensures balanced current sharing; low Qg (10.2nC) reduces gate driver losses and EMI across both phases. |
| Medical Imaging Power Supply | Smart Building Lighting Controller |

IC Role / Device Role / Timing Role: Output synchronous rectifier in forward converter secondary side; operated in continuous conduction mode. Use Value: 100% UIS-tested body diode withstands leakage inductance spikes during MOSFET turn-off; low VSD (0.9V typ.) improves light-load efficiency. | Use Scenario: DALI-compatible LED driver module with integrated dimming, surge protection, and thermal foldback. IC Role / Device Role / Timing Role: Dual-channel high-side switch controlling separate warm-white and cool-white LED strings.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH4014LPS-13 | Same die, PowerDI5060-8/SWP (Type UXD) package with thinner profile (0.735mm max height vs. 0.61mm) and modified pad layout. | Better suited for ultra-low-profile assemblies where Z-height <0.8mm is mandatory; slightly higher RθJA due to reduced copper area. | Select when board thickness constraint overrides thermal optimization needs. |
| DMN3029LSD-13 | 30V VDSS, 2.9mΩ RDS(on) @ 10V, SO-8 package; lower voltage rating but significantly lower on-resistance. | Optimized for 12V systems only; unsuitable for 24V+ transient conditions; lacks 175°C rating and UIS certification. | Choose only for cost-sensitive 12V consumer applications where ambient temperature stays below +125°C. |
Compared with DMTH4014LPS-13, the -13 variant offers superior thermal performance via Type C's larger thermal pad contact area; versus DMN3029LSD-13, it trades lower RDS(on) for higher voltage robustness, extended temperature range, and production-validated avalanche immunity-critical for industrial and transportation-grade reliability.

FAQ
What is the maximum continuous drain current for DMTH4014LPD-13 at 100°C case temperature?
The maximum continuous drain current is 30.8A at TC = +100°C, as specified in the Absolute Maximum Ratings table. This value assumes proper PCB thermal design with 2oz copper and thermal vias to maintain case temperature at the stated limit; exceeding this current without adequate heatsinking risks thermal runaway.
Does DMTH4014LPD-13 support logic-level gate drive?
Yes-its RDS(on) is guaranteed at 4.5VGS (25mΩ max), making it compatible with standard 5V logic outputs and microcontroller GPIOs without external level shifters. Gate threshold voltage ranges from 1.0V to 3.0V, ensuring reliable turn-on with 4.5V drive while maintaining noise immunity.
How is thermal performance validated for this dual MOSFET?
Thermal resistance is characterized as RθJC = 3.5°C/W (junction-to-case) and RθJA = 62.6°C/W (junction-to-ambient, FR-4, 2oz copper). These values are measured per JEDEC standards using calibrated test boards; the exposed drain pad must be fully soldered to a minimum 1-inch² copper area with ≥6 thermal vias for RθJC compliance.
Is DMTH4014LPD-13 qualified for automotive applications?
While not AEC-Q101 certified out-of-box, Diodes states that automotive-grade versions are available upon request with PPAP documentation and IATF 16949 manufacturing. The base part shares the same die and process as qualified variants and meets key automotive requirements including 175°C operation, 100% UIS testing, and halogen-free construction.
