Product details
Overview
DMT10H032LK3-13 from Diodes Incorporated is a 100V N-channel enhancement-mode MOSFET in TO252 (DPAK) package, rated for 26A continuous drain current at TC = +25°C, with RDS(ON) of 32mΩ @ VGS = 10V and 48mΩ @ VGS = 4.5V, optimized for high-efficiency DC-DC converters and LED backlighting power stages.
For engineers reviewing the DMT10H032LK3-13 datasheet, DMT10H032LK3-13 pinout, DMT10H032LK3-13 application, or DMT10H032LK3-13 equivalent, key selection criteria include its 100% production-tested UIS capability, low Qg (11.9 nC @ VGS = 10V), junction-to-case thermal resistance of 3.4°C/W, and AEC-Q101 readiness for automotive-grade power management designs.
Technical Context
This MOSFET employs planar trench-gate technology to achieve low RDS(ON) and fast switching dynamics. Its gate threshold voltage (1.3–2.5V) enables compatibility with 3.3V and 5V logic-level drive, while the 104A pulsed drain current rating supports robust transient handling in synchronous buck topologies.
The device integrates a body diode with 31.5ns reverse recovery time and 94.6nC QRR, supporting efficient freewheeling in hard-switched converters. Thermal design is enabled by its 3.4°C/W RθJC and validated 25.3mJ single-pulse avalanche energy (IAS = 13A, L = 0.3mH).
Key Specifications

|---|---|
| VDSS | 100V - Supports input rails up to 80V DC-DC converters with 20% margin |
| RDS(ON) | 32mΩ @ VGS = 10V - Limits conduction loss to ≤5.1W at 26A |
| Qg | 11.9nC @ VGS = 10V - Enables <100ns turn-on with 3Ω gate driver |
| EAS | 25.3mJ - Withstands unclamped inductive switching events without failure |

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 |
|---|---|---|---|
| DMT10H032LQ3-13 | Same die, QFN-8 (3×3mm) package with enhanced thermal performance (RθJC = 2.5°C/W) | Better suited for space-constrained, high-power-density designs requiring bottom-side cooling | Select when board area is limited and thermal interface to PCB is optimized |
| IPB100N10N3 G | 100V, 100A, TO-263 package; RDS(ON) = 9.5mΩ @ VGS = 10V; higher Qg = 65nC | Higher current capacity but slower switching; requires stronger gate driver | Select only when peak current >30A is required and switching frequency <100kHz |
Compared with DMT10H032LK3-13, the DMT10H032LQ3-13 offers superior thermal resistance in a smaller footprint, while the IPB100N10N3G trades faster switching for higher current handling-making the DMT10H032LK3-13 optimal for mid-power, high-frequency DC-DC and backlighting where balance of RDS(ON), Qg, and cost is critical.

FAQ
What is the maximum safe operating junction temperature for DMT10H032LK3-13?
The absolute maximum junction temperature is +150°C, and the device is characterized over -55°C to +150°C. Derating begins at TJ > 125°C per Figure 5 and Figure 6; sustained operation above 135°C requires active thermal management due to RDS(ON) increase and reduced UIS margin.
Can DMT10H032LK3-13 be driven directly from a 3.3V microcontroller GPIO?
Yes-it has a gate threshold voltage range of 1.3V to 2.5V, ensuring reliable turn-on at 3.3V. However, full enhancement (to achieve 32mΩ RDS(ON)) requires ≥4.5V VGS; for optimal efficiency, use a dedicated gate driver or level shifter when operating at high current or high frequency.
Is DMT10H032LK3-13 qualified to AEC-Q101?
Diodes states that "for automotive applications requiring specific change control (i.e., parts qualified to AEC-Q100/101/200…) please contact us or your local representative." The DMT10H032LK3-13 is built on an AEC-Q101-capable process and uses IATF 16949-certified facilities, but formal AEC-Q101 certification requires customer-specific PPAP documentation.
What is the recommended PCB pad layout for thermal performance?
Per Diodes' suggested layout for TO252, use a minimum 1-inch² (25.4mm × 25.4mm) 2oz copper pad connected to the drain tab via multiple thermal vias (≥6 × 0.3mm diameter). Pad dimensions should match D = 6.10mm and E = 6.58mm outlines, with solder mask defined to maximize thermal transfer.
