Infineon introduces the first 15 V trench power MOSFETs with OptiMOS™ 7 technology in PQFN packages

Munich, Germany – 28 November 2023 – The ever-increasing power demand in data centers and computing applications requires advancements in power efficiency and compact power supply design. Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) responds to trends on the system level by introducing its new OptiMOS™ 7 family, industry’s first 15 V trench power MOSFET technology. The OptiMOS 7 15 V series primarily targets optimized DC-DC conversion for servers, computing, datacenter, and artificial intelligence applications.

The product portfolio includes the latest PQFN 3.3 x 3.3 mm² Source-Down, with bottom- and dual-side cooling variants in standard- and center-gate footprints. The portfolio also includes a robust PQFN 2 x 2 mm² variant with a reinforced clip. The OptiMOS 7 15 V technology is specifically tailored for DC-DC conversions with low output voltages, particularly in server and computing environments. This advancement aligns with emerging shifts towards high ratio DC-DC conversion in data-center power distribution.

Compared to the established OptiMOS5 25 V, the new OptiMOS 7 15 V achieves a reduction of R _DS(on) and FOMQ _g by ~30 percent, and FOMQ _OSS by ~50 percent by lowering the breakdown voltage. The PQFN 3.3 x 3.3 mm² Source-Down package variants provide a more versatile and effective PCB-design. Furthermore, the PQFN 2 x 2 mm² package provides a pulsed current capability higher than 500 A and a typical R _thJC of 1.6 K/W. By minimizing conduction and switching losses and incorporating advanced packaging technology, thermal management becomes easy and effective, setting new benchmarks both for power density and overall efficiency.

Availability

The OptiMOS 7 15 V product portfolio can be ordered now and is available in two package sizes: PQFN 3.3 x 3.3 mm² Source-Down variants and PQFN 2 x 2 mm². More information is available at www.infineon.com/optimos-7-15v.
