Diodes Incorporated has announced the availability of the first in a new generation of discrete MOSFETs. The DMN3012LEG delivers increased efficiency in a smaller package to provide significant cost, power, and space savings in a wide variety of power conversion and control applications.

The DMN3012LEG integrates dual MOSFETs in a single package measuring just 3.3x3.3mm and reduces the board space requirement by up to 50% compared to a typical two-chip solution. This space saving benefits a range of applications using point of load (PoL) and power management modules. The DMN3012LEG can be used in DC/DC synchronous buck converters and half-bridge power topologies to reduce the size of power converter solutions.

The 3D structure of the PowerDI 3333-8 Type D package helps to increase overall power efficiency, while the high voltage and current ratings make it widely applicable. The fully-grounded pad design delivers good thermal performance, allowing the total solution to run cooler. The high switching speeds and efficiency of the process used also minimize the need for large inductors and capacitors.

The DMN3012LEG integrates two N-channel enhancement mode MOSFETs, making it well suited for synchronous buck converter designs. Using a lateral diffused MOS (LDMOS) process, it combines fast turn-on and turn-off delay speeds of 5.1nS and 6.4nS for Q1, and 4.4nS and 12.4ns for Q2.

The device has maximum on-resistance (RDS(ON)) figures of just 12mΩ at Vgs=5V for Q1 and 6mΩ at Vgs=5V for Q2. The DMN3012LEG can accept a 30V drain-source voltage with ten volt gate-source, while supporting five volt gate drive.

The DMN3012LEG is available now priced at $0.589 each in 1,000 piece quantities.
