Product details
Overview
DMT8012LFG-13 from Diodes Incorporated is an N-channel enhancement-mode MOSFET optimized for high-efficiency power management, featuring 80V V(BR)DSS, 16mΩ RDS(ON) @ 10V VGS, and 35A ID at TC = +25°C in a POWERDI®3333-8 package. It serves as a synchronous rectifier or primary switching element in DC-DC converters where low conduction loss and fast switching are critical.
For engineers reviewing the DMT8012LFG-13 datasheet, DMT8012LFG-13 pinout, DMT8012LFG-13 application, or DMT8012LFG-13 equivalent, key selection criteria include its 4.2°C/W RθJC thermal resistance, 34nC total gate charge at 10V, 100% UIS-rated ruggedness, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This MOSFET employs advanced trench-gate technology to achieve low RDS(ON) while maintaining controlled Qgd × RDS(ON) figure-of-merit (FOM) of ~72 mΩ·nC, enabling efficient operation in hard-switched and synchronous rectification topologies. Its gate threshold voltage (1.0–3.0V) ensures compatibility with standard 3.3V and 5V logic-level drivers.
The device integrates a robust body diode with 30.2ns trr and 34.6nC Qrr, supporting high-frequency flyback and buck converter operation. Thermal design is facilitated by its low junction-to-case resistance and thermally enhanced POWERDI®3333-8 package, which delivers 30W power dissipation capability at TC = +25°C.

|---|---|
Use Scenario: Replaces Schottky diode in secondary-side synchronous rectification of isolated 12V→3.3V/5V buck-boost converters. IC Role / Device Role / Timing Role: Low-side N-channel switch synchronized to primary-side PWM timing; conducts during freewheeling phase. Use Value: Reduces forward voltage drop from ~0.4V to <50mV at 12A, improving efficiency by ≥3% over full load range. | Use Scenario: High-current switch in constant-current LED driver for automotive instrument cluster backlighting (12V input, 350mA × 12 strings). IC Role / Device Role / Timing Role: PWM-controlled current sink; modulates LED brightness at 1–20kHz with minimal thermal rise. Use Value: 16mΩ RDS(ON) limits power dissipation to <2W at 12A peak, enabling single-device solution without heatsink. |
| Industrial 24V Input Buck Converter | Server VRM High-Density Power Stage |
Use Scenario: Main switching FET in 24V input, 12V/30A output buck regulator for PLC I/O modules.

FAQ
What is the maximum continuous drain current rating for DMT8012LFG-13 at TC = +70°C?
The maximum continuous drain current is 28A at TC = +70°C, as specified in the Absolute Maximum Ratings table. This rating assumes proper PCB copper area for heat spreading and accounts for RDS(ON) increase with junction temperature. Derating curves in Figure 5 confirm 28A aligns with 150°C TJ limit under steady-state conditions.
Does DMT8012LFG-13 support logic-level gate drive?
Yes-it has a gate threshold voltage range of 1.0V to 3.0V and delivers 14mΩ RDS(ON) at VGS = 6V, enabling direct drive from 3.3V or 5V microcontrollers without level-shifting. However, full 16mΩ spec is guaranteed only at VGS = 10V, so 6V operation requires verification of worst-case RDS(ON) in thermal design.
How is the POWERDI®3333-8 package thermally superior to SO-8?
The POWERDI®3333-8 features an exposed drain pad directly bonded to PCB copper, achieving 4.2°C/W RθJC-over 3× better than SO-8's typical 15°C/W. Its 3.3mm × 3.3mm footprint also reduces parasitic inductance by ~40%, improving EMI performance in high-dI/dt switching applications.
Is DMT8012LFG-13 suitable for automotive infotainment power supplies?
Yes-its AEC-Q101 qualification, −55°C to +150°C operating range, and 100% UIS rating make it appropriate for 12V-input buck converters powering infotainment SoCs. The low Crss (10pF) prevents false turn-on during load dump transients, and green packaging complies with automotive ELV directives.
