Product details
Overview
DMTH4008LPS-13 from Diodes Incorporated is a 40V, 175°C-rated N-channel enhancement-mode MOSFET in PowerDI5060-8 package, optimized for high-efficiency power switching with 8.8 mΩ RDS(ON) @ VGS = 10 V, 64.8 A continuous drain current at TC = +25°C, and robust 100% unclamped inductive switching (UIS) rating-used in BLDC motor drives and automotive-grade DC-DC converters.
For engineers reviewing the DMTH4008LPS-13 datasheet, DMTH4008LPS-13 pinout, DMTH4008LPS-13 application, or DMTH4008LPS-13 equivalent, key selection criteria include RDS(ON) vs. temperature stability, junction-to-case thermal resistance (2.7°C/W), +175°C operation capability, and PowerDI5060-8 layout compatibility for high-current PCB thermal management.
Technical Context
This MOSFET employs a trench-gate silicon process to achieve low on-resistance while maintaining fast switching (tD(ON) = 4.3 ns, tD(OFF) = 16.7 ns) and low gate charge (Qg = 15.3 nC @ VGS = 10 V). Its body diode exhibits tRR = 20.2 ns and QRR = 8.9 nC under 10 A/100 A/μs conditions-critical for synchronous rectification and freewheeling in hard-switched topologies.
The device is qualified per AEC-Q standards for automotive reliability and features a green, halogen- and antimony-free molding compound (UL 94V-0), matte tin-annealed terminals, and moisture sensitivity level 1-enabling lead-free reflow without preconditioning. Junction-to-case thermal path is optimized via an exposed drain pad for direct heatsink coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40 V - Maximum blocking voltage before avalanche; supports 24 V and 36 V nominal bus systems with margin. |
| RDS(ON) | 8.8 mΩ @ VGS = 10 V - Enables <1 W conduction loss at 30 A, reducing thermal load in compact power stages. |
| ID (TC = 25°C) | 64.8 A - Continuous current rating when case temperature is maintained at 25°C via heatsinking. |
| TJ Range | –55°C to +175°C - Fully specified operation up to 175°C junction temperature for under-hood automotive use. |
| Qg | 15.3 nC @ VGS = 10 V - Determines gate drive power requirement; enables efficient 500 kHz+ switching with standard drivers. |
| RθJC | 2.7°C/W - Thermal resistance from junction to exposed drain pad; allows precise heatsink sizing for thermal design. |
| EAS | 25.7 mJ - Avalanche energy rating confirms ruggedness during inductive turn-off transients without failure. |
Pinout & Package
Package: PowerDI5060-8 - thermally enhanced surface-mount package with exposed drain pad (8-terminal configuration), UL 94V-0 molded plastic, 0.097 g mass, and JEDEC-compliant footprint for high-current PCB routing and thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control terminal; requires ≤±20 V drive; low input capacitance (Ciss = 1088 pF) minimizes driver loading. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH4008LPSQ-13 | Automotive-qualified variant (AEC-Q101); identical electrical specs but with extended traceability and PPAP support. | Required for OEM automotive production; not needed for industrial or consumer designs. | Select when automotive qualification documentation and lot-level test reports are mandatory. |
| IPB180N04S4-02 | 40 V, 180 A, 2.0 mΩ RDS(ON); TO-263 package; higher current, lower RDS(ON), larger footprint. | Suitable for higher-power inverters (>10 kW); requires larger PCB area and different thermal interface. | Choose only if system demands >100 A continuous current and can accommodate TO-263 mechanical constraints. |
Compared with DMTH4008LPSQ-13, the base part lacks automotive documentation but offers identical performance and cost advantage for non-automotive use; versus IPB180N04S4-02, it trades lower RDS(ON) for smaller size and lower gate charge-ideal for space-constrained 30–60 A applications.

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The DMTH4008LPS-13 supports 45.8 A continuous drain current at TC = +100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits of the PowerDI5060-8 package and must be verified against actual board-level thermal resistance and ambient conditions using the provided RθJC = 2.7°C/W value.
Does this MOSFET require a gate resistor for safe operation?
A gate resistor is recommended to dampen ringing and control dV/dt during switching-typical values range from 2.2 Ω to 10 Ω depending on drive strength and layout parasitics. The device's low gate resistance (Rg = 2.6 Ω) and 15.3 nC total gate charge make it compatible with standard 1–2 A peak gate drivers without external buffering.
Is the PowerDI5060-8 package compatible with standard reflow profiles?
Yes-the PowerDI5060-8 is qualified for lead-free reflow per J-STD-020 Level 1 (MSL 1), meaning it can withstand standard Pb-free peak temperatures up to 260°C without preconditioning. The matte tin-annealed terminals ensure reliable wetting and intermetallic formation during standard SAC305 soldering processes.
How does the body diode performance compare to external Schottky diodes?
The integrated body diode delivers VSD = 0.8 V (typ.) at 10 A and tRR = 20.2 ns-comparable to medium-voltage Schottkys but with tighter parameter distribution and no separate component placement. While Schottkys offer lower forward drop, this MOSFET's body diode eliminates extra BOM items and simplifies layout in synchronous rectifiers where gate timing controls conduction.
