Product details
Overview
DMTH4005SPS-13 from Diodes Incorporated is a 40V, 100A N-channel enhancement-mode MOSFET in PowerDI5060-8 package, rated for +175°C operation and optimized for high-efficiency power conversion in automotive body control and engine management systems. It delivers 3.7mΩ RDS(ON) at VGS = 10V, 49.1nC total gate charge, and 100% unclamped inductive switching (UIS) capability.
For engineers reviewing the DMTH4005SPS-13 datasheet, DMTH4005SPS-13 pinout, DMTH4005SPS-13 application, or DMTH4005SPS-13 equivalent, key selection criteria include high-temperature junction rating, low conduction loss at 50A–100A DC current, thermal resistance of 1°C/W (junction-to-case), and compatibility with 10V gate drive in space-constrained DC-DC converter designs.
Technical Context
This MOSFET employs trench-gate silicon technology to achieve ultra-low RDS(ON) while maintaining robust avalanche ruggedness (EAS = 132.3mJ). Its 100% UIS qualification ensures reliable operation under inductive load switching transients common in motor drivers and solenoid controls.
The device features a thermally enhanced PowerDI5060-8 package with exposed drain pad for direct heatsinking, enabling 150W power dissipation at TC = +25°C. Gate threshold voltage (2–4V) supports standard 5V/10V logic-level drive without requiring level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40V - Maximum blocking voltage for 12V/24V automotive rail applications with margin against load-dump transients. |
| RDS(ON) max | 3.7mΩ @ VGS = 10V - Enables ≤3.7W conduction loss at 100A, critical for high-current DC-DC phase legs. |
| ID continuous @ TC = 25°C | 100A - Sustains full-rated current when mounted on heatsink, supporting high-power body electronics modules. |
| Qg | 49.1nC - Low gate charge reduces driver power demand and switching losses in 100–500kHz converters. |
| TJ max | +175°C - Qualified per AEC-Q standards for under-hood environments including engine control units. |
| RθJC | 1°C/W - Enables precise thermal modeling from junction to heatsink interface in compact power modules. |
| EAS | 132.3mJ - Confirmed avalanche energy rating allows safe operation during inductive turn-off without snubbers. |

FAQ
Is DMTH4005SPS-13 qualified for automotive applications?
Yes, DMTH4005SPS-13 meets JEDEC reliability standards referenced in AEC-Q200 for passive components and is designed for automotive environments. For full AEC-Q101 qualification-including stress testing and lot traceability-the pin-compatible DMTH4005SPSQ-13 variant is available and recommended for production automotive systems.
What is the maximum continuous drain current at 100°C case temperature?
The datasheet specifies 100A continuous drain current at TC = +25°C and maintains 100A up to TC = +100°C (Note 6). This reflects its thermal design: with RθJC = 1°C/W, it sustains full rated current across a wide case temperature range when properly heatsunk.
Can DMTH4005SPS-13 be driven directly by a 3.3V microcontroller GPIO?
No. With a gate threshold voltage range of 2–4V and requiring 10V for full RDS(ON) specification (3.7mΩ), a 3.3V GPIO cannot fully enhance the device. It would operate in linear region with high conduction loss. A gate driver or level shifter supplying ≥10V is required for efficient switching.
Does the PowerDI5060-8 package require special PCB layout considerations?
Yes. The exposed drain pad must be connected to a large copper pour (≥250mm² recommended) with ≥6 thermal vias (0.3mm diameter) to inner ground/power planes. Suggested pad dimensions (X1=4.10mm, Y2=3.81mm, G1=0.82mm) are provided in the datasheet to ensure mechanical reliability and optimal thermal transfer.
