Product details
Overview
DMTH45M5SFVWQ-13 from Diodes Incorporated is an AEC-Q101-qualified 40V N-channel enhancement-mode MOSFET in PowerDI3333-8/SWP package, delivering 5.5 mΩ RDS(ON) @ VGS = 10 V, 71 A continuous drain current at TC = +25°C, and rated for operation up to +175°C junction temperature - designed for automotive backlighting, DC-DC converters, and power-management functions.
For engineers reviewing the DMTH45M5SFVWQ-13 datasheet, DMTH45M5SFVWQ-13 pinout, DMTH45M5SFVWQ-13 application, or DMTH45M5SFVWQ-13 equivalent, key selection criteria include its wettable flank package for automated optical inspection, 100% production-tested UIS robustness, low Qgd × RDS(ON) figure-of-merit, and IATF 16949-certified manufacturing with PPAP support.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low conduction loss and fast switching in high-temperature automotive environments. Its gate threshold voltage (2.0–3.5 V) enables reliable turn-on with standard 3.3 V or 5 V logic-level drivers, while the 1.5 Ω gate resistance supports controlled dV/dt and EMI management in hard-switched topologies.
The device integrates a robust body diode with 61.3 ns reverse recovery time and 52.1 nC QRR, enabling efficient synchronous rectification and freewheeling in buck, boost, and half-bridge configurations. Thermal design is enabled by RθJC = 2.9 °C/W and RθJA = 42 °C/W on FR-4, with the exposed drain pad providing direct thermal path to PCB copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40 V - Maximum blocking voltage for 12 V/24 V automotive bus systems with transient margin. |
| RDS(ON) Max | 5.5 mΩ @ VGS = 10 V - Ensures ≤14 W conduction loss at 71 A, critical for thermally constrained modules. |
| ID Continuous | 71 A @ TC = +25°C - Supports high-current power stages without external heatsinking when mounted on ≥1″² 2 oz copper. |
| Qg | 13.2 nC - Enables <5.4 ns turn-on delay with 3.5 Ω gate resistor, suitable for 500 kHz+ switching. |
| EAS | 21 mJ - Confirmed avalanche energy rating ensures survivability during inductive load switching faults. |
| TJ Range | −55°C to +175°C - Validated operation across full automotive under-hood temperature envelope. |
| Wettable Flank | Yes - Exposed side terminals enable automated optical inspection (AOI) of solder joint integrity on SMT assembly lines. |

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 |
|---|---|---|---|
| STL135N4LF8AG | RDS(ON) = 3.8 mΩ @ 10 V, but rated only to +150°C; no wettable flank; Qg = 22 nC. | Better conduction loss at lower temp, but unsuitable for under-hood >+150°C zones; AOI not supported. | Select if thermal budget allows lower TJ and optical inspection is not required. |
| IPB180N04S4-02 | RDS(ON) = 1.8 mΩ @ 10 V, TO-263-7 package, RθJC = 1.4 °C/W, but no AEC-Q101 certification stated in public datasheet. | Higher current capability (180 A), but lacks PPAP documentation and automotive qualification evidence. | Select only for non-safety-critical industrial applications where AEC-Q101 is not mandated. |
Compared with STL135N4LF8AG and IPB180N04S4-02, DMTH45M5SFVWQ-13 uniquely balances +175°C operation, wettable flank AOI compatibility, and AEC-Q101/PPAP readiness - making it the preferred choice for thermally demanding, volume automotive production where traceability and visual process control are mandatory.

FAQ
Is DMTH45M5SFVWQ-13 qualified for automotive use per AEC-Q101?
Yes - DMTH45M5SFVWQ-13 is fully AEC-Q101 qualified, manufactured in IATF 16949-certified facilities, and supported by PPAP documentation. It undergoes rigorous stress testing including HTGB, HTRB, UHAST, and 100% UIS screening to meet automotive reliability standards.
What is the thermal resistance from junction to case (RθJC) and how should it be used in layout?
RθJC is 2.9 °C/W, measured from junction to the soldering point on the exposed drain pad. To achieve this value, the PCB must provide ≥1″² of 2 oz copper connected directly to the drain pad via multiple thermal vias - critical for sustaining 71 A continuous current without exceeding +175°C junction temperature.
Does DMTH45M5SFVWQ-13 support logic-level gate drive?
It has a gate threshold voltage range of 2.0–3.5 V, allowing turn-on with 3.3 V or 5 V microcontroller outputs. However, full RDS(ON) specification (5.5 mΩ) requires VGS = 10 V; for logic-level operation, RDS(ON) rises to ~12 mΩ at VGS = 4.5 V - acceptable for lower-current applications but increases conduction loss.
How does the wettable flank feature improve manufacturing yield?
The wettable flank exposes vertical sidewalls of pins 1 (G) and 8 (D) for solder meniscus formation during reflow. This enables automated optical inspection (AOI) to verify solder fillet height and wetting quality - reducing field failures from insufficient solder joints in high-vibration automotive assemblies.
