Product details
Overview
DMTH10H030LK3 from Diodes Incorporated is a 100V, 28A N-channel enhancement-mode MOSFET in TO252 (DPAK) package, featuring 30mΩ RDS(ON) at VGS = 10V and rated for continuous operation up to +175°C. It delivers low conduction loss and fast switching for high-efficiency DC-DC converters and LED backlighting in automotive and industrial power management systems.
For engineers reviewing the DMTH10H030LK3 datasheet, DMTH10H030LK3 pinout, DMTH10H030LK3 application, or DMTH10H030LK3 equivalent, key selection criteria include its AEC-Q101 qualification, 100% unclamped inductive switching rating, thermal robustness at 175°C junction temperature, and low QG (33.3nC) for optimized gate drive efficiency.
Technical Context
This MOSFET employs planar trench-gate technology to achieve low RDS(ON) while maintaining rugged avalanche performance (EAS = 85mJ, IAS = 7.5A). Its gate threshold voltage (1.4–3.5V) enables reliable turn-on with standard logic-level drivers, and its body diode exhibits low forward voltage (1.3V at 20A) with controlled reverse recovery (QRR = 51.9nC).
The device is characterized for operation across –55°C to +175°C ambient, with RDS(ON) normalized to ≤1.3× typical at 175°C. Thermal resistance from junction-to-case is fixed at 2°C/W, enabling predictable heatsinking in compact PCB layouts using FR-4 with 2oz copper and recommended pad dimensions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 100V - Supports input rails up to 80V DC-DC stages with 20% safety margin. |
| RDS(ON) | 30mΩ @ VGS = 10V - Limits conduction loss to ≤12W at 20A, critical for thermally constrained designs. |
| ID (TC = 25°C) | 28A - Sustains high-current switching in synchronous buck converters without derating. |
| QG | 33.3nC - Enables efficient 1MHz+ switching with <1W gate drive power using 5V logic drivers. |
| TJ max | +175°C - Certified for under-hood automotive and industrial environments without forced cooling. |
| EAS | 85mJ - Withstands repetitive inductive energy spikes in motor drives and solenoid control. |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive power electronics including HTGB, HTRB, and UIS. |
Pinout & Package
Package: TO252 (DPAK), surface-mount, single-die N-channel MOSFET with exposed drain pad for thermal conduction. Molded green compound, UL 94V-0 rated, 0.33g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal (S) | Low-side return path; connects directly to ground plane for minimal loop inductance in switching nodes. |
| Pin 2 (Gate) | Control terminal (G) | High-impedance input requiring <1µA leakage; sensitive to ESD but compatible with 3.3V/5V microcontroller outputs. |
| Pin 3 (Drain) | Power output terminal (D) | Exposed metal tab - electrically connected to drain; must be soldered to large copper area for thermal dissipation and electrical isolation. |
Key Features
| Feature | Design Value |
|---|---|
| 100% Unclamped Inductive Switching (UIS) | Rated for 7.5A avalanche current and 85mJ single-pulse energy - eliminates need for external snubbers in relay/motor drive circuits. |
| Low QG/QGD ratio | QGD = 5.1nC / QG = 33.3nC → 15.3% - reduces Miller-induced shoot-through risk and improves hard-switching stability. |
| High-temperature RDS(ON) stability | RDS(ON) increases only ~1.3× from 25°C to 175°C - maintains predictable efficiency over full operating range. |
| AEC-Q101 qualification | Passed HTGB (1500h @ 150°C), HTRB (1000h @ 175°C), and UIS - validated for automotive power modules and engine control units. |
| Green RoHS-compliant construction | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); matte tin annealed leadframe ensures MIL-STD-202 solderability. |
Applications
| Automotive Body Control Module (BCM) | Industrial DC-DC Buck Converter |
|---|---|
Use Scenario: Driving 12V solenoids and relays in door lock, headlight, and HVAC actuators. IC Role / Device Role / Timing Role: High-side or low-side power switch controlling inductive loads with integrated flyback energy handling. Use Value: Eliminates external freewheeling diode and clamping circuitry due to 100% UIS rating and robust body diode (VSD = 1.3V @ 20A). |
Use Scenario: Primary switch in 48V-to-12V isolated or non-isolated buck converter for factory automation PLCs. IC Role / Device Role / Timing Role: Main power FET operating at 300kHz–1MHz with synchronous rectification support. Use Value: 30mΩ RDS(ON) and 33.3nC QG enable >95% efficiency at 20A load while maintaining thermal margin at 85°C ambient. |
| LED Backlight Driver (Automotive Display) | Telecom Power Supply (Hot-Swap Circuit) |
Use Scenario: Constant-current switching regulator for 24–48V LED strings in instrument cluster and infotainment displays. IC Role / Device Role / Timing Role: PWM-controlled high-side switch regulating LED current via feedback loop. Use Value: +175°C rating allows placement near heat-generating display drivers without thermal throttling or derating. |
Use Scenario: OR-ing and hot-swap protection in redundant 48V telecom power shelves. IC Role / Device Role / Timing Role: Load switch with fast turn-off (<28ns total switching time) to prevent backfeed during insertion. Use Value: Low RDS(ON) minimizes voltage drop during steady-state operation; fast tF = 8.1ns limits fault propagation during transient events. |
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 |
|---|---|---|---|
| DMTH10H025LK3 | Lower RDS(ON): 25mΩ @ 10V; identical package, voltage rating, and AEC-Q101 qualification. | Higher conduction efficiency at high current; slightly higher gate charge (35.5nC vs. 33.3nC). | Select when minimizing I²R loss dominates over gate drive power or cost sensitivity. |
| IPB120N10N3 G | 100V, 120A, TO263 package; RDS(ON) = 9.5mΩ @ 10V; higher current capability but larger footprint and no AEC-Q101. | Requires larger PCB area and heatsink; suitable for non-automotive high-power supplies where qualification is not required. | Choose only if system demands >28A continuous current and automotive qualification is unnecessary. |
Compared with DMTH10H025LK3, this part trades 5mΩ lower on-resistance for marginally higher QG; compared with IPB120N10N3 G, it offers AEC-Q101 compliance and DPAK compatibility at the expense of current rating and package size.

FAQ
Is DMTH10H030LK3 suitable for high-frequency switching above 500kHz?
Yes - with QG = 33.3nC and QGD = 5.1nC, it supports clean 1MHz switching when paired with a 1Ω gate resistor and 5V driver. Measured tR = 7.0ns and tF = 8.1ns confirm suitability for hard-switched topologies with minimal overlap loss.
What is the maximum allowable PCB copper area for thermal performance in TO252?
Per datasheet Note 6, a 1-inch square (25.4mm × 25.4mm) 2oz copper pad reduces RθJA from 69°C/W to 42°C/W. Larger copper areas yield diminishing returns; thermal simulation shows optimal benefit up to ~30mm × 30mm with thermal vias to inner layers.
Does the body diode support synchronous rectification?
No - the intrinsic body diode has VSD = 1.3V at 20A and tRR = 37.9ns, making it unsuitable for synchronous rectification. External Schottky or MOSFET-based synchronous rectifiers are required for high-efficiency secondary-side switching.
Can DMTH10H030LK3 replace DMTH10H025LK3 without layout changes?
Yes - both share identical TO252 package outline, pinout, and thermal pad geometry. The 5mΩ RDS(ON) difference does not affect mechanical fit or solder profile, though gate drive strength should be verified for worst-case VGS(TH) variation (1.4–3.5V).
