Product details
Overview
DMN3029LFG-13 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in POWERDI3333-8 package, rated for 30V VDS, 18.6mΩ RDS(on) @ 10V VGS, and 8.0A continuous drain current at 25°C. It delivers low conduction loss and fast switching for high-efficiency DC-DC converters and LED backlighting circuits.
For engineers reviewing the DMN3029LFG-13 datasheet, DMN3029LFG-13 pinout, DMN3029LFG-13 application, or DMN3029LFG-13 equivalent, this device supports compact power management designs requiring AEC-Q101 qualification, 100% UIS rating, and thermally efficient 33% board-area reduction versus SO-8.
Technical Context
This MOSFET employs planar trench-gate technology to achieve low RDS(on) while maintaining controlled gate charge (Qg = 11.3nC @ 10V) and fast switching (tD(off) = 19.5ns). Its 100% Rg tested gate resistance ensures consistent turn-on/turn-off timing across production lots.
The device operates across –55°C to +150°C junction temperature range and is qualified to AEC-Q101 standards. Thermal resistance of 62.5°C/W (with 2" × 2" 2 oz Cu PCB) enables stable performance in space-constrained automotive and industrial power stages.

FAQ
What is the maximum continuous drain current at 70°C ambient?
The DMN3029LFG-13 supports 6.3A continuous drain current at TA = +70°C when mounted on a 2" × 2" FR-4 PCB with 2 oz copper (Note 6). This derating reflects thermal resistance of 62.5°C/W and junction-to-ambient temperature rise limit of 80°C above ambient.
Is the POWERDI3333-8 package lead-free and RoHS compliant?
Yes. The DMN3029LFG-13 features matte tin annealed over copper leadframe, fully compliant with EU RoHS Directive 2011/65/EU and halogen/antimony-free "Green" specifications (<900ppm Br, <900ppm Cl, <1000ppm Sb).
Does this MOSFET require a gate resistor for safe operation?
A gate resistor is recommended to dampen ringing and control dV/dt. With Qg = 11.3nC and typical gate driver output impedance, a 5–10Ω series resistor ensures stable 100ns-scale switching transitions and minimizes EMI in high-frequency DC-DC applications.
Can DMN3029LFG-13 be used in linear mode (constant-current regulation)?
No. This MOSFET is optimized for switching operation only. Its Safe Operating Area (SOA) limits linear-mode use to short pulses (<100µs) at low VDS; sustained linear operation risks thermal runaway due to positive RDS(on) temperature coefficient and limited SOA at high VDS/ID.
