Product details
Overview
DMT3003LFGQ-13 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET qualified to AEC-Q101, with RDS(ON) = 3.2 mΩ @ VGS = 10 V, 100 A continuous drain current at TC = +25°C, and PowerDI®3333-8 package. It serves as a high-current synchronous rectifier or power switch in automotive DC-DC converters, backlighting drivers, and power-management modules.
For engineers reviewing the DMT3003LFGQ-13 datasheet, DMT3003LFGQ-13 pinout, DMT3003LFGQ-13 application, or DMT3003LFGQ-13 equivalent, this part supports design validation for AEC-Q101-compliant automotive systems requiring low conduction loss, robust unclamped inductive switching (100% production-tested), and thermally efficient board-level integration in space-constrained layouts.
Technical Context
This MOSFET employs trench-gate silicon technology optimized for low QGD × RDS(ON) figure-of-merit (FOM), enabling fast switching with minimal gate drive energy in high-frequency DC-DC topologies. Its 2 Ω·mm² RθJC thermal resistance and exposed drain pad support direct heatsinking in compact automotive modules.
The device features a 16 A avalanche current rating (IAS) and 250 mJ single-pulse avalanche energy (EAS), validated per JEDEC JESD24-1. Gate threshold voltage (VGS(TH)) is tightly specified at 1–3 V, ensuring reliable turn-on with standard 3.3 V or 5 V logic-level controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum drain-source blocking voltage compatible with 24 V automotive battery systems and 12 V rail regulation. |
| RDS(ON) | 3.2 mΩ @ VGS = 10 V - Enables ≤0.64 W conduction loss at 40 A, critical for thermally constrained DC-DC converter designs. |
| ID (continuous) | 100 A @ TC = +25°C - Supports high-current output stages without parallel devices in 300–500 kHz buck converters. |
| QG | 44 nC @ VGS = 10 V - Low total gate charge reduces driver power demand and enables efficient operation with integrated gate drivers. |
| RθJC | 2 °C/W - Thermal path from junction to case allows direct mounting to PCB copper pour or heatsink, sustaining >60 W dissipation. |
| EAS | 250 mJ - Confirmed avalanche ruggedness ensures reliability during load dump or inductive flyback events in automotive power stages. |
Pinout & Package
Package: PowerDI®3333-8 - Thermally enhanced 8-pin surface-mount package with exposed drain pad (pins 4, 5, 6, 7, 8) for low-impedance heat transfer and 33% smaller board area vs. SO-8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Source | Common return path for load current; electrically tied to internal source metallization and thermal pad on bottom side. |
| 2 | Source | Parallel source connection to reduce package inductance and improve current sharing in high-di/dt applications. |
| 3 | Gate | Control terminal with ±20 V maximum rating; low input capacitance (Ciss = 2370 pF) minimizes driver stress. |
| 4–8 | Drain | Exposed copper drain pad (pins 4, 5, 6, 7, 8) provides primary thermal and electrical path to PCB ground plane or heatsink. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) × QGD FOM | Enables high-efficiency, high-frequency (>1 MHz) switching in automotive DC-DC converters without sacrificing thermal margin. |
| 100% production-tested UIS | Guarantees avalanche robustness across full production lot-no screening required for safety-critical automotive power stages. |
| AEC-Q101 qualification & PPAP support | Validated for automotive use with full change control, IATF 16949 manufacturing, and traceable lot documentation. |
| PowerDI3333-8 footprint | Reduces board area by 67% vs. SO-8 while delivering 3× higher thermal performance-enables denser ECU and ADAS module layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPB180N04S4-02 | 40 V VDSS, 1.8 mΩ RDS(ON) @ 10 V, TO-263 package, higher RθJA (40 °C/W) | Higher voltage margin but larger footprint and lower thermal efficiency; requires external heatsink for >50 A operation. | Select when 40 V system margin is mandatory and board space permits TO-263 mounting. |
| STL220N3LLH6 | 30 V VDSS, 2.2 mΩ RDS(ON) @ 10 V, PowerFLAT 5x6 package, no AEC-Q101 certification | Lacks PPAP documentation and automotive qualification; suitable only for industrial-grade non-safety systems. | Choose only for cost-sensitive non-automotive applications where AEC-Q101 compliance is not required. |
Compared with IPB180N04S4-02 and STL220N3LLH6, DMT3003LFGQ-13 delivers optimal balance of AEC-Q101 compliance, thermal density (2 °C/W RθJC), and board-area efficiency-making it the preferred choice for space-constrained, high-reliability automotive power stages.

FAQ
What is the maximum allowable gate-source voltage for DMT3003LFGQ-13?
The absolute maximum gate-source voltage is ±20 V, as specified in the Absolute Maximum Ratings table. Operation beyond this range risks permanent gate oxide damage. For reliable 12 V gate drive, a 15 V clamp or Zener protection is recommended to prevent overshoot during fast switching transitions.
Does DMT3003LFGQ-13 require a gate resistor for automotive applications?
Yes-a series gate resistor (typically 2–10 Ω) is required to dampen ringing, limit peak gate current, and control dV/dt during turn-on/turn-off. The device's 0.6 Ω intrinsic gate resistance and 44 nC total gate charge make external resistance essential for EMI control and MOSFET longevity in noisy automotive environments.
Can DMT3003LFGQ-13 be used in parallel configurations?
Yes, but only with matched gate drive layout and current-sharing resistors. Its positive temperature coefficient of RDS(ON) (normalized increase to 1.5× at 150°C) supports inherent current balancing; however, layout asymmetry must be minimized to avoid thermal runaway in multi-device arrays.
Is the PowerDI3333-8 package lead-free and RoHS compliant?
Yes-the device uses matte tin annealed over copper leadframe and conforms to EU RoHS 2015/863/EU, with bromine and chlorine <900 ppm each and antimony <1000 ppm. It is also halogen- and antimony-free per Diodes' "Green" definition, certified to UL 94V-0 flammability rating.
