Product details
Overview
DMTH8008SPSWQ-13 from Diodes Incorporated is an AEC-Q101-qualified 80V N-channel enhancement-mode MOSFET in PowerDI5060-8/SWP package, delivering 7.8mΩ RDS(ON) at VGS = 10V, 92A continuous drain current at TC = +25°C, and rated for operation up to +175°C junction temperature-designed specifically for high-reliability automotive DC-DC converters and load switches.
For engineers reviewing the DMTH8008SPSWQ-13 datasheet, DMTH8008SPSWQ-13 pinout, DMTH8008SPSWQ-13 application, or DMTH8008SPSWQ-13 equivalent, key selection criteria include its 100% production-tested UIS capability, low RDS(ON) enabling high-efficiency power conversion, thermal robustness in under-hood environments, and PPAP-supporting IATF 16949 manufacturing traceability.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low conduction loss and fast switching in high-temperature automotive power stages. Its 1.5°C/W RθJC enables efficient heat transfer to the PCB copper pad, while the integrated body diode supports synchronous rectification and freewheeling in buck and half-bridge topologies.
The device features gate charge values of Qg = 34nC (VGS = 10V), Qgd = 12nC, and Ciss = 1950pF at VDS = 40V, supporting controlled turn-on/turn-off timing with minimal Miller-induced shoot-through risk in high-frequency (>200kHz) DC-DC applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 80V - Withstands transient overvoltage spikes common in 48V automotive systems without breakdown. |
| RDS(ON) | 7.8mΩ @ VGS = 10V - Minimizes conduction loss in high-current paths (e.g., <1.2W loss at 40A). |
| ID (TC = +25°C) | 92A - Supports high-power load switching and converter primary-side current handling. |
| TJ Operating Range | –55°C to +175°C - Enables deployment in engine bay, transmission control, and ADAS ECU locations. |
| EAS | 80mJ - Sustains unclamped inductive energy during fault conditions without failure. |
| Qg / Qgd | 34nC / 12nC - Enables predictable gate drive sizing and reduces switching loss in PWM-controlled stages. |
| RθJC | 1.5°C/W - Allows direct thermal coupling to PCB copper, eliminating need for external heatsinks in many designs. |

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 |
|---|---|---|---|
| STL220N6F7AG | 60V VDSS, 1.7mΩ RDS(ON), PowerFLAT 5x6 package, lower voltage rating but superior on-resistance. | Restricted to 24V/48V systems only; unsuitable for 80V transients in 48V+ architectures. | Select when system max VDS ≤ 60V and ultra-low RDS(ON) is prioritized over voltage margin. |
| IXTQ80N25P | 250V VDSS, 25mΩ RDS(ON), TO-220 package, higher voltage rating but larger footprint and no AEC-Q101 certification. | Lacks automotive qualification and thermal performance (RθJC = 1.2°C/W but no exposed pad optimization). | Choose only for industrial non-automotive 80V+ applications where qualification and miniaturization are not required. |
Compared with STL220N6F7AG and IXTQ80N25P, DMTH8008SPSWQ-13 uniquely balances 80V robustness, AEC-Q101 compliance, and thermally optimized PowerDI5060-8 packaging-making it the only qualified option for space-constrained, high-temperature automotive power stages requiring both voltage headroom and production traceability.

FAQ
What is the maximum continuous drain current at TC = +100°C?
The DMTH8008SPSWQ-13 supports 65A continuous drain current at case temperature +100°C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limitations of the PowerDI5060-8 package and must be validated against actual board layout and airflow conditions using the provided RθJC = 1.5°C/W and transient thermal resistance curves.
Is the body diode suitable for synchronous rectification?
Yes-the integrated body diode has VSD = 0.8–1.2V at IS = 14A and tRR = 43ns, enabling use in synchronous rectification within buck converters. However, external Schottky diodes or dedicated synchronous MOSFETs may offer lower forward drop in high-efficiency designs above 95% target efficiency.
Does this part require a gate driver IC for automotive 12V logic control?
No-its VGS(TH) range of 2–4V allows direct drive from standard 3.3V or 5V microcontroller GPIOs, though a dedicated gate driver (e.g., TC4427) is recommended for >200kHz switching to ensure fast, low-loss transitions and mitigate shoot-through in half-bridge configurations.
How is moisture sensitivity managed during reflow soldering?
The DMTH8008SPSWQ-13 is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to reflow. Standard lead-free reflow profiles (peak 260°C) are supported, and the matte tin annealed terminals ensure reliable solder joint formation per MIL-STD-202, Method 208.
