Product details
Overview
DMNH3010LK3-13 from Diodes Incorporated is a 30V, 55A N-channel enhancement-mode MOSFET in TO252 (DPAK) package, featuring 9.5mΩ RDS(ON) @ VGS = 10V and 11.5mΩ @ 4.5V, rated for continuous operation up to +175°C junction temperature, and qualified to AEC-Q101 - used in high-efficiency DC-DC converters and automotive power management.
For engineers reviewing the DMNH3010LK3-13 datasheet, DMNH3010LK3-13 pinout, DMNH3010LK3-13 application, or DMNH3010LK3-13 equivalent, key selection criteria include RDS(ON) at low gate drive (4.5V), UIS ruggedness, thermal resistance (RθJC = 2.5°C/W), AEC-Q101 qualification, and TO252 thermal pad layout compatibility.
Technical Context
This MOSFET employs trench-gate silicon technology optimized for low conduction loss and fast switching with controlled Qg (37nC @ 10V) and low Crss (138pF), enabling high-frequency synchronous buck operation. Its 100% production-tested UIS capability supports robust inductive load handling without external snubbers.
The device's RDS(ON) exhibits <5% variation from −55°C to +175°C at VGS = 10V, and gate threshold voltage (VGS(TH) = 1.0–2.5V) remains stable across temperature, ensuring reliable turn-on in wide-ambient automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Maximum drain-source blocking voltage; defines safe operating range in 24V automotive and 12V industrial systems. |
| RDS(ON) @ 10V | 9.5mΩ - Enables ≤10W conduction loss at 55A; critical for thermally constrained DPAK PCB layouts. |
| RDS(ON) @ 4.5V | 11.5mΩ - Supports logic-level gate drive from 3.3V/5V controllers without level-shifting circuitry. |
| ID (TC = 25°C) | 55A - Continuous drain current rating under ideal heatsink conditions; derates to 40A at TC = 100°C. |
| RθJC | 2.5°C/W - Junction-to-case thermal resistance enables direct copper-plate mounting for high-power dissipation. |
| EAS | 75mJ - Avalanche energy rating ensures single-pulse inductive switching survivability without clamping diodes. |
| AEC-Q101 | Qualified - Validated for automotive powertrain and body electronics per stress test requirements (HTOL, TC, HTRB). |
Pinout & Package
Package: TO252 (DPAK), surface-mount, 3-terminal plastic case with exposed thermal pad (Drain-connected). Molded green compound, UL 94V-0 rated, 0.33g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control input | Receives gate drive signal; requires ≤20V absolute max; 2.4Ω gate resistance limits dV/dt-induced ringing. |
| 2 (Drain) | High-side switch node | Connected to internal die backside; electrically tied to exposed thermal pad for low-inductance heat path. |
| 3 (Source) | Power return / reference | Serves as local ground reference for gate drive; must be routed with low inductance to minimize shoot-through risk. |
Key Features
| Feature | Design Value |
|---|---|
| +175°C rated operation | Enables deployment in engine bay, transmission control, and under-hood modules without derating penalties. |
| 100% UIS tested | Guarantees avalanche robustness in flyback, boost, and motor drive circuits with unclamped inductive loads. |
| Low Qgd/Qgs ratio (5.9nC/6.1nC) | Reduces Miller-induced false turn-on during high-dV/dt commutation, improving hard-switching reliability. |
| Halogen- and antimony-free | Meets automotive OEM green material specifications (<900ppm Br+Cl, <1000ppm Sb) without compromising solderability. |
| Matte tin finish | Ensures consistent wetting and intermetallic formation on FR-4 and heavy copper PCBs per MIL-STD-202. |
Applications
| Automotive Body Control Module | Industrial DC-DC Converter |
|---|---|
Use Scenario: High-side load switching for LED headlamps and HVAC actuators in 12V/24V vehicle electrical architecture. IC Role / Device Role / Timing Role: N-channel high-side switch controlled by microcontroller GPIO with charge pump or bootstrap gate driver. Use Value: 11.5mΩ RDS(ON) at 4.5V enables direct drive from 5V MCU outputs; 175°C rating avoids thermal shutdown during prolonged lamp-on cycles. |
Use Scenario: Synchronous rectifier in 300kHz, 12V-to-5V buck converter powering FPGA I/O rails in factory automation PLCs. IC Role / Device Role / Timing Role: Low-side synchronous FET replacing Schottky diode to reduce conduction loss and improve efficiency. Use Value: 9.5mΩ RDS(ON) cuts resistive loss by >60% vs. 40V Schottky; fast tF = 10.7ns minimizes dead-time losses. |
| Automotive Infotainment Power Supply | LED Backlight Driver |
Use Scenario: Input protection and reverse polarity protection in 12V infotainment head unit power entry stage. IC Role / Device Role / Timing Role: N-channel MOSFET configured in ideal diode configuration with external controller for low-loss OR-ing. Use Value: Low VGS(TH) (1.0–2.5V) allows precise turn-on control; 100% UIS testing prevents failure during load dump transients. |
Use Scenario: PWM dimming switch in 24V LED backlight for commercial displays and medical monitors. IC Role / Device Role / Timing Role: High-speed switching element modulating current through LED strings at 1–20kHz. Use Value: Fast tR = 19.6ns and tF = 10.7ns ensure clean PWM edges; low Coss = 190pF reduces switching loss at high frequency. |
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 |
|---|---|---|---|
| STL130N3LLH6 | 30V, 130A, 2.8mΩ @ 10V, PowerFLAT 5x6 package, RθJC = 1.4°C/W - lower RDS(ON) but higher gate charge (55nC). | Requires larger PCB area and more aggressive gate drive due to higher Qg; better suited for high-current, low-frequency inverters. | Select when peak current >80A and thermal interface allows smaller footprint; avoid if gate drive is limited to 5V logic. |
| IRLML0030TRPBF | 30V, 2.1A, 50mΩ @ 4.5V, SOT-23 package, RθJA = 260°C/W - much lower current rating and higher RDS(ON). | Only suitable for sub-1A loads; lacks AEC-Q101 qualification and UIS rating. | Use only for space-constrained, low-power bias rails; not a functional replacement for DMNH3010LK3-13 in power switching roles. |
Compared with STL130N3LLH6 and IRLML0030TRPBF, DMNH3010LK3-13 uniquely balances 55A current capacity, 4.5V logic-level drive, AEC-Q101 compliance, and TO252 thermal performance - making it optimal for mid-power automotive and industrial switching where board space, gate drive simplicity, and reliability are jointly constrained.

FAQ
What is the maximum allowable gate-source voltage for DMNH3010LK3-13?
The absolute maximum VGS is ±20V per the datasheet's Maximum Ratings table. Operation beyond this risks permanent gate oxide damage. For reliable 10V drive, use a gate clamp (e.g., 15V Zener) or regulated gate driver to prevent overshoot during fast switching transitions.
Can DMNH3010LK3-13 be used in a high-side configuration with 12V supply?
Yes - but requires a gate drive voltage ≥10V referenced to the source terminal. In high-side operation, a bootstrap or isolated gate driver is necessary to lift the gate above the drain potential; direct 12V MCU drive is unsafe unless source is near ground (i.e., low-side configuration).
Is the exposed thermal pad electrically connected, and how should it be handled on the PCB?
The TO252 thermal pad is internally connected to the Drain terminal. It must be soldered to a large copper pour tied to the drain net for thermal and electrical integrity. Use ≥3 thermal vias (0.3mm diameter) under the pad to inner ground/power planes to achieve specified RθJC and RθJA performance.
Does DMNH3010LK3-13 have integrated ESD protection on the gate?
No - the device has no built-in gate ESD protection diodes. External gate protection (e.g., 12V TVS or RC snubber) is recommended in systems exposed to handling or system-level ESD events, especially in automotive assembly environments per ISO 10605.
