Product details
Overview
DMTH6005LK3-13 from Diodes Incorporated is a 60V, 90A N-channel enhancement-mode MOSFET in TO252 (DPAK) package, featuring 4.5mΩ typical RDS(ON) at VGS = 10V and rated for continuous operation up to +175°C junction temperature. It delivers low conduction loss and fast switching performance for high-efficiency power conversion in automotive body control and engine management systems.
For engineers reviewing the DMTH6005LK3-13 datasheet, DMTH6005LK3-13 pinout, DMTH6005LK3-13 application, or DMTH6005LK3-13 equivalent, key selection criteria include its 1.5°C/W RθJC, 47.1nC total gate charge at 10V, 100% unclamped inductive switching rating, AEC-Q qualified automotive variant (DMTH6005LK3Q), and TO252 thermal pad layout compatibility.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) while maintaining robust avalanche capability (EAS = 98mJ, IAS = 14.8A). Its gate threshold voltage (1–3V) enables direct drive from 3.3V/5V logic with sufficient noise margin, and its low Qg/Qgd ratio supports high-frequency synchronous rectification.
The device integrates a fast-recovery body diode (tRR = 40.4ns, QRR = 49.7nC) and exhibits stable on-resistance over temperature (±15% variation from −55°C to +175°C at VGS = 10V), making it suitable for thermally constrained under-hood environments without derating penalties.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60V - Supports 48V nominal automotive and industrial bus systems with 20% safety margin. |
| RDS(ON) max | 5.6mΩ @ VGS = 10V - Enables ≤0.25W conduction loss at 70A continuous drain current. |
| ID (TC = 25°C) | 90A - Package-limited continuous current with adequate heatsinking on PCB copper pad. |
| RθJC | 1.5°C/W - Enables direct thermal coupling to heatsink or metal-core PCB for high-power density designs. |
| Qg | 47.1nC @ VGS = 10V - Determines gate driver power requirement and switching transition time in hard-switched topologies. |
| EAS | 98mJ - Specifies single-pulse avalanche energy handling without failure under inductive load turn-off stress. |
| TJ max | +175°C - Qualified for under-hood automotive applications per AEC-Q101 requirements. |
Pinout & Package
DMTH6005LK3-13 uses the TO252 (DPAK) surface-mount package with exposed drain pad for thermal and electrical connection. The three terminals are arranged in standard DPAK orientation: Gate (left), Source (center), Drain (right, tab-connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Gate) | Control electrode | Receives 0–10V logic-level signal; requires <0.66Ω gate resistance for optimal EMI and dV/dt control. |
| S (Source) | Reference node for gate drive and current return path | Common source connection for half-bridge or low-side switch configurations; ties to power ground plane. |
| D (Drain) | Main current output terminal | Connected to exposed copper pad on underside; must be soldered to ≥1in² 2oz copper for 100W dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| +175°C rated junction temperature | Enables operation in engine bay or powertrain modules without thermal derating below 125°C ambient. |
| 100% unclamped inductive switching (UIS) tested | Guarantees reliability in DC-DC converters with freewheeling inductors where clamp circuits are omitted. |
| Low Qg/Qgd ratio (47.1nC / 12.5nC) | Reduces Miller-induced shoot-through risk and improves controllability in high-side synchronous buck stages. |
| RoHS-compliant, halogen- and antimony-free "Green" construction | Meets EU Directive 2015/863/EU and automotive OEM environmental compliance requirements. |
| AEC-Q101 qualified variant available (DMTH6005LK3Q) | Provides traceable qualification data for automotive production programs requiring PPAP documentation. |

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 |
|---|---|---|---|
| IXTP50N10P | 100V VDSS, 5.0mΩ RDS(ON), TO-220 package, no AEC-Q qualification | Higher voltage margin but larger footprint and inferior thermal resistance (RθJC = 2.0°C/W) | Prefer when board space permits and >60V transients are expected; avoid for automotive under-hood use. |
| STL220N6F7 | 60V VDSS, 3.2mΩ RDS(ON), PowerFLAT 5x6 package, AEC-Q101 qualified | Lower RDS(ON) but smaller thermal pad area limits power handling to 75W (vs. 100W for DMTH6005LK3-13) | Select when PCB real estate is constrained and peak power <75W; verify layout thermal relief matches spec. |
Compared with IXTP50N10P and STL220N6F7, DMTH6005LK3-13 uniquely balances 100W power capability, TO252 manufacturability, and AEC-Q-ready qualification-making it optimal for cost-sensitive, thermally demanding automotive power stages where both reliability and thermal performance are critical.

FAQ
What is the maximum continuous drain current for DMTH6005LK3-13 at 100°C case temperature?
The datasheet specifies 70A continuous drain current at TC = +100°C. This value reflects thermal limitation of the TO252 package under realistic PCB heatsinking conditions-not silicon capability-and assumes proper copper pad layout per Diodes' recommended footprint.
Does DMTH6005LK3-13 require a gate resistor for stable operation?
Yes-a gate resistor between 5Ω and 22Ω is recommended to dampen ringing, limit peak gate current, and control dV/dt during switching. The device's 0.66Ω intrinsic gate resistance alone is insufficient to prevent oscillation with typical PCB trace inductance and driver output impedance.
Is the exposed drain pad electrically connected to the drain terminal?
Yes-the TO252 package's large exposed copper pad on the bottom side is internally bonded to the drain metallization. It must be soldered to a dedicated PCB copper pour tied to the drain net for both thermal conduction and current carrying capacity.
How does the body diode performance compare to discrete Schottky diodes in synchronous rectification?
The body diode has VSD = 1.2V at 20A and tRR = 40.4ns, which is slower and higher forward drop than most Schottky diodes-but its integration eliminates layout parasitics and enables precise timing control in synchronous gate drivers, yielding net system efficiency gains above 200kHz.
