Small-outline MOSFETs deliver low losses at low gate-drive voltage

For applications requiring a low footprint and threshold voltage with high thermal performance, Zetex Semiconductors’ is offering six new low-voltage MOSFETs in surface-mount packages, including SO-8, SOT23 and a leadless package measuring just 2mm x 2mm.

The ZXMN2F34MA, in a DFN322 package, is rated to 20V and has on-resistance of 60mΩ at 4.5V gate-to-source voltage and 120mΩ at 2.5V. The device displays enhanced thermal performance compared to larger devices of similar ratings, with around 40% lower package thermal resistance enabling cooler running and improved power density. Its mounted height of 0.85mm combines with the small footprint to help designers save PCB area in space-constrained power-conversion and power-management applications.
