Product details
Overview
DMT31M6LPS from Diodes Incorporated is an N-channel enhancement-mode power MOSFET in PowerDI®5060-8 (Type K) package, rated for 30V VDSS, 1.35mΩ RDS(ON) @ VGS = 10V, and 150A ID at TC = +25°C. It serves as a high-current synchronous rectifier or main switch in DC-DC converters for server VRMs and GPU power stages.
For engineers reviewing the DMT31M6LPS datasheet, DMT31M6LPS pinout, DMT31M6LPS application, or DMT31M6LPS equivalent, key selection criteria include its ultra-low RDS(ON) at 4.5V gate drive, 100% unclamped inductive switching rating, and thermally optimized exposed-drain PowerDI package for high-density board layouts.
Technical Context
This MOSFET uses trench-gate silicon technology to achieve low Qgd × RDS(ON) figure-of-merit (FOM), enabling fast switching with minimal conduction loss. Its gate threshold voltage (1–3V) supports both 5V and 3.3V logic-level drive, and the integrated body diode exhibits 37.2ns reverse recovery time at 500A/μs dI/dt.
The device is characterized for operation from –55°C to +150°C junction temperature, with RθJC = 1.2°C/W enabling direct thermal coupling to PCB copper or heatsinks. Its SOA curve supports single-pulse operation up to 160A with 10μs pulse width under VDS = 15V conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Maximum drain-source blocking voltage before avalanche onset |
| RDS(ON) | 1.35mΩ @ VGS = 10V - Enables <1.5W conduction loss at 100A continuous current |
| ID (TC = 25°C) | 150A - Continuous drain current rating when mounted on infinite heatsink |
| Qg | 123nC @ VGS = 10V - Total gate charge determining driver strength requirement |
| RθJC | 1.2°C/W - Junction-to-case thermal resistance enabling efficient heat transfer via exposed drain pad |
| EAS | 325mJ - Avalanche energy rating confirming robustness in inductive switching applications |
| tRR | 37.2ns - Body diode reverse recovery time supporting high-frequency synchronous rectification |
Pinout & Package
Package: PowerDI®5060-8 (Type K), surface-mount, thermally enhanced with exposed drain pad. Molded green compound, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 (Drain pads) | Drain (D) | Eight parallel drain terminals connected to large exposed copper pad - primary thermal and current path |
| Pin 1 (top-left corner marker) | Source (S) | Left-side source terminal - used for gate drive reference and low-side sensing |
| Pin 2 (adjacent to Pin 1) | Gate (G) | Single gate input - requires <123nC charge for full enhancement; low Rg = 0.94Ω aids switching speed |
| Remaining S pins (3–8 on left side) | Source (S) | Additional source connections - reduce source inductance and improve current sharing in paralleled configurations |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(ON) at 4.5V | 2.4mΩ - enables use with 3.3V or 5V PWM controllers without gate boosting |
| 100% UIS-rated | 25.5A IAS, 325mJ EAS - guarantees safe operation during inductive turn-off transients in buck converters |
| Thermally optimized package | RθJC = 1.2°C/W - allows >100W power dissipation with minimal ΔT across junction-to-pad interface |
| Green, RoHS-compliant construction | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb) - meets automotive and industrial environmental compliance mandates |
| Low Qgd × RDS(ON) FOM | Qgd = 24.5nC, RDS(ON) = 1.35mΩ - reduces switching loss and improves efficiency in 500kHz+ DC-DC stages |
Applications

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 |
|---|---|---|---|
| DMTH3010LPS-13 | 30V VDSS, 1.1mΩ RDS(ON) @ 10V, but only rated for 120A ID at TC = 25°C | Lower current handling limits use in >130A phases; identical PowerDI5060-8 footprint | Select when lower RDS(ON) is prioritized over peak current capability |
| IPB017N10N5ATMA1 | 100V VDSS, 1.7mΩ RDS(ON), TO-263-7 package, RθJC = 0.7°C/W | Higher voltage rating sacrifices conduction efficiency at 30V; larger footprint and different thermal interface | Choose only if system requires 60V+ blocking margin or existing TO-263 layout reuse |
Compared with DMTH3010LPS-13, DMT31M6LPS delivers +25% higher continuous current capacity while maintaining sub-1.4mΩ on-resistance; versus IPB017N10N5ATMA1, it trades voltage headroom for 30% lower RDS(ON) and 20% smaller board area in 30V applications.

FAQ
What is the maximum allowable gate-source voltage for DMT31M6LPS?
The absolute maximum VGS rating is ±20V. Operation beyond this risks irreversible gate oxide damage. Recommended gate drive is 4.5V to 10V for optimal RDS(ON) and switching loss trade-off; 12V drive is permissible but offers diminishing returns above 10V due to gate charge saturation.
Can DMT31M6LPS be used in parallel configurations?
Yes - its low RDS(ON) tolerance (typical 1.1mΩ, max 1.35mΩ) and matched thermal coefficient support current sharing. Use Kelvin source connections and symmetrical PCB layout with equal-length gate traces; derate total current by 15% for thermal imbalance in 4+ device arrays.
Does DMT31M6LPS meet AEC-Q101 requirements for automotive use?
No - the DMT31M6LPS is not AEC-Q101 qualified. Diodes offers automotive-grade variants (e.g., DMT31M6LPSQ-13) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening; consult Diodes' automotive product definitions page for qualification status.
What is the recommended PCB pad layout for thermal performance?
Use the official PowerDI5060-8 (Type K) pad layout from Diodes' package outline document: 4.9mm × 5.8mm exposed drain pad with ≥8 thermal vias (0.3mm diameter, 0.8mm pitch) connecting to inner-layer copper planes. Minimum 2oz copper on top/bottom layers and 1-inch² thermal pad on secondary layer required to achieve RθJA ≤ 50°C/W.
