Small-signal MOSFETs in ultra-small SOT883 outperform larger rivals

The PMZxxxxN series of small-signal MOSFETs from NXP Semiconductors offer an ultra-small SOT883 package measuring 1.0mm x 0.6mm with 0.5mm profile, featuring best-in-class switching speed and very low on-resistance for small size and high power efficiency.

The devices achieve comparable power dissipation and performance to SOT23 devices but occupy only 14% of the PCB space. By using Quad Flat Non-leaded (QFN) package technology, these new transistors not only save board space but also reduce or eliminate parasitic effects associated with electrical and thermal resistivity of leads. This combination of superior thermal performance with on-resistance of less than 0.65Ω at 2.5V supports higher current-carrying capacity than other similarly-sized MOSFETs. The new series also achieves turn-on times between 12-16ns and turn-off times between 17-24ns, enabling high-frequency operation for increased efficiency and smaller filtering components.
